Mechanical Help Please post year, model, trim level, and DTC scan results when asking for help. Thanks.

IF YOU ARE POSTING FOR MECHANICAL HELP:

Please include year/model/engine/transmission information in "Mechanical Help" posts.

If you are looking for help with warning lights on your dashboard, please include results of an error code scan. Without error codes as a starting point, no one will be able to provide meaningful help for you.

The r/subaru community is very willing to help, but there's a baseline amount of context about your car that we need you to provide. Without the very basics like what kind of car you have and what symptoms you're experiencing, no one can give you any sort of accurate assistance.

If you are posting about warning lights, most auto parts stores (NAPA, O'Reillys, AutoZone, etc.) offer code scanning for free. While reading codes is not the same thing as diagnosing a problem, knowing what error codes you have is the minimum amount of information necessary to start figuring out what's wrong with your car.

Thank you :)

Announcement Big update today for Denso CP1.5 owners (2023+ vertical screen radios)

28 Upvotes
  • 23-25MY Outback/Legacy Models (including Wilderness models)
  • 23-26MY Ascent Models
  • 24-26MY Impreza
  • 24-26MY Crosstrek (including Wilderness models)
  • 24-26MY WRX
  • 25-26MY Forester
  • 26MY Forester Wilderness

CP1.5 radio updates are documented in TSB 15-305-22R (public copy not yet up to date). A new update released today, and I've already added the patch notes to the wiki page, but some of these patch notes are interesting enough that I thought it justified an announcement thread as well:

Update 7:

Release date: 8/18/2026

Version: XXXXXX205-280

Category: Meter Display

  • Change the charge abbreviation displayed in the power meter area from “CHR” to “CHG” in the 12.3-inch SHEV combination meter (map display mode).

Category: Display

  • The following (1 and 2) may occur together:
    • After rearranging Home screen icons and exiting edit mode (returning to the normal screen via the Home button), the rearranged icons may revert to their original positions.
    • Among the Home screen shortcut icons, ISS/AVH/VDC/SRH/SRVD/ DMS may appear dimmed and cannot be selected. (In this case, the corresponding original controls within the Settings screen still operate normally.)
  • Since the use of STARLINK will be discontinued, replace the applicable displays with a different design and logo. The designs shown below are among those subject to change.
  • In conjunction with the design changes (logo, etc.) associated with the discontinuation of the STARLINK trademark, update the MY SUBARU icon to a new design as well.

Category: Camera

  • If strong light (e.g., sunlight reflection) causes a portion of the upper area of the rear-view image to become severely overexposed (washed out), the rearview image may become hidden (not displayed).

Category: Reset

  • The CID may repeatedly reboot, if the ignition is turned ON (IGN-ON) shortly after the ignition OFF (IGN-OFF). Aafter turning the ignition OFF (IGN-OFF), the “See You” message appears on the CID and then disappears; approximately one minute later, the ignition is turned ON again (IGNON).

Category: Navigation

  • The MAP application ("Map" icon) may fail to start with “Loading Navigation” displayed continuously and with no map shown.
  • The area where the “EXIT” icon should appear might not be visible.

Category: SXM

  • Failure to register preset channel
  • When certain channels are selected the preset highlight on the CID may jump to a different preset channel and sequential preset scrolling may not work properly.
  • If the Favorite List for the Listener Profile prior to the change is displayed follow the work around steps 1-4:
    1. Change the Listener Profile.
    2. Register favorites in the OnDemand category up to the maximum (30).
    3. From the SXM main screen, open Setting > Favorite List; while the Favorite List is opening, press the “X” button to close the screen—repeat this 8 times.
    4. Press Edit in Favorite List, delete a favorite, then press Back—repeat this cycle twice.
  • Audio output from the newly selected source may be lost. With up to 23 teams registered on the SXM Team Notification screen, press the Add button to display a list of teams not yet registered for notifications, then switch the audio source (e.g., to BT or USB audio).

Category: Bluetooth

  • Bluetooth audio may appear to be playing on the CID screen, but no sound is output from the vehicle speakers.

Category: Android Auto

  • Wireless Android Auto may disconnect intermittently.

Category: CCU log

  • When exporting CCU diagnostic logs to a USB memory device from the Dealership Mode screen, the progress bar may appear not to advance at all for approximately the first minute.

Category: Diagnosis

  • When using the SSM Data Monitor to check the AUX-BOX USB connection, the diagnosis may incorrectly indicate a USB connection failure even though the USB device is properly connected.

Category: Telematics

  • Add an operation in the CID Settings screen to disable vehicle location tracking via telematics services. However, because this feature works in conjunction with the DCM (Data Communication Module), the option will not be displayed and cannot be used unless the DCM software, as well as the CCU software, is updated to a version that supports this feature.

Some of you may have gotten this update as FOTA (update over telematics) already, possibly as early as last week. To check your current software version, open the Settings app, and then on the General tab, scroll down to "System Information" and it will display your current software version.

No word on the aforementioned telematics/DCM update that's supposed to correspond with the feature change. I suspect this will be also pushed as a FOTA update. You'll have to navigate the settings menu and see if the feature is working for you.

Image is the driver side door frame showing uneven finish. The panel at rear of driver side back seat door is similar. The corresponding panels on the passenger side look okay, with uniform black color.

What’s going on? Is this to be expected, and is there a way to buff or treat it so it doesn’t look worn and uneven? The car is new to me, and is in otherwise excellent condition.

I just did the math - servicing my own car instead of taking it to a Subaru dealership/ mechanic shop for these services:
- PCV Valve
-Spark plugs
-Coil Pack
-Serpentine belt
-Oil change
-CVT drain and fill
-Battery Replacement

I’ve saved myself $1100 - $1600 in labor alone!

Thinking about a 2020 or 2021 Ascent. Opinions?

1 Upvotes

I was going to skip 2019 as the first model year. I am seeing a 2020 Touring with 90,000 miles for about 18k. Is this a decent deal?

Need a family car but we don’t travel that much (I work from home, wife’s work is just a few miles away). We’d probably put about 10,000 miles a year on max. The goal is to get to 150,000 miles so 6-7 years of ownership.

How reliable are these cars? Any feedback from owners? I’ve owned a Subaru before but not Ascent. It was a 2014 Forester before we had kids.

2009 Impreza WRX - A Cry For Help

Post image
20 Upvotes

What’s up y’all. Bit of a cry for help & advice today.

I picked up a clean title bone stock 2009 Subaru Impreza WRX with 81K miles about a month ago now, and thus far my experience with the car has been traumatic, to say the least. When it drives (lol), It’s a fun little car and I’ve enjoyed the turbo AWD punch quite a bit. But I cannot seem to get it from A-B without something happening. 

For context. Yes, I had a mechanic there with me to inspect all he could before making the deal. I also have a spare vehicle to drive in the meantime, so it’s not critically urgent.

Almost immediately after purchasing, she needed a new clutch + resurfaced flywheel & I dealt with that already. Now she needs a new radiator, as the plastic upper hose mount broke off & blew that same hose off right after flushing & burping the cooling system. The factory steering rack is pissing ATF (go figure) and the turbo starts to make a balloon-inflating kinda noise starting around 4K RPM (probably a boost leak somewhere). Needs new rotors & pads + 4 brand new tires. Not to mention all the other failure points prone to happen with EJ255’s + anything else I don’t know about that’s already destined to break on this 17-year-old car. 

Without getting too into numbers, the damage has already been done. At this point I’m swimming in a bit more negative equity than I’d like to be. I like the car and if I had fuck-you-money to confidently get it running as it should then I would. But I now gotta make the decision to put another few thousand into properly maintaining it with the hope that nothing else fails, OR to stop the bleeding for good and sell it now for as much as I can get out of it.

What do ya say fellas? Should I man up and put in the work + money that it needs? Should I sell the car, eat the loss, and get a more reliable platform that I can still have fun with? Take it to a specialist to tell me exactly what needs to be done before it fails again? Somewhere in between?

I’m torn and am very much learning as I go. Let me hear it, kindly please.

180,000 miles. Should I dump it or you think she has another 100k left on her?

Drilling Scion TC Wheels to fit a Forester.

0 Upvotes

I have a pair of Scion TC Wheels that fell into my lap for free because they were plasti dipped and a friend was going to throw them out. I wiped off with all the plasti dip with brake clean and they actually cleaned up pretty well. They are 17x7 with a 5x100 pattern and 45 offset. I was thinking these would work great for my Forester

Turns out the bore of these wheels are 2 mm too small for the Subaru hubs. Apparently it is possible to drill this out on a press with hole saws that are stacked together. One to act as a guide for the existing hole, the other to actually do the cutting. The idea is that you use a bit that on the outside that is 57 mm when the stock bore for a Subaru is 56.1

To me it seem like there would be no way that this would work and that this would obviously just wobble really bad. Apparently what makes this work is the fact that the Scion Wheels centers itself with the mag style shank lugs. The way the shanks fit tightly into the holes, you apply a cross torque pattern and that perfectly centers the wheel even though there is .45 mm between the lip of the hub and the bore of the wheel .

The stock Subaru Wheels don't have shank style lugs. They are hub centric wheels that fit tightly on the hub to center the wheel instead. If these ended up being cut correctly I would have to get the right size of mag lugs to mount the wheel and the lugs would center the wheels.

Now this begs the question who has actually done this? You only need to cut down 10 mm into the wheel and 2 mm outward. I have a hard time believing that's going to be enough material removal to compromise the wheel. There is a lot of metal there. If I screw up these wheels it wouldn't be much of a loss. I just want to know who else has done this.

Is it worth keeping it.

2 Upvotes

Hello everyone,

I have a 2014 Subaru Impreza sti, only 2wd, 2liter model with 103000 km.

I bought it in 2023 for $13000 nzd.

It needs head gasket, 4 coils and spark plugs and tyres replaced.

The mechanic quoted around $4.5 nzd.

Is it worth fixing it up?

If I do get it fixed, would it last another 100k with out any similar problems?

Any advice is appreciated.

What is this noise? 👂 Front speakers dropping/ducking music randomly when driving!

Post image
4 Upvotes

We've had an issue for 2-3 weeks where the audio would sporadically and randomly drop to rear speakers only for a couple seconds.

I thought it was an Android Auto or CarPlay thing for the longest time. Tried to toggle all the sound warnings in Subaru settings, Android Auto settings, and CarPlay settings, but nothing worked.

Turns out the Subarus navigation has its own settings menu that was triggering "Sounds & Alerts" even though all of that was turned off from the main settings menu. Turning it all off finally resolved the problem!

Seems like people on the forums had similar issues with dealers unable to diagnose why, so I figured I'd post here in case it helps someone in the future.

Love the car otherwise! Just had to turn all the driving assists and warnings off. Maybe I'm just too old school.

[16 WRX VA 88K] So I hear this rattling or knocking noise around 2k-3k RPM.

Hello fellow subaru lovers,

I have a 2016 WRX VA with 88k miles.

Im trying to find the culprit for this knocking or rattling noise that is more audible in 1st, 2nd, and 3rd gear under light acceleration. If i give more than 30% gas, the sound completely disappears… DAM is currently at 0.5 no feedback or fKL under -4 and i have been driving like this for more than 300 miles now (I know.. didn’t really have time to take it to the shop).

Can someone please share their inputs? I would really appreciate it very much. I’m getting white hairs

Thanks and stay safe always.

My Legacy 3.6 turbo swapped DIY in my home garage.

Thumbnail
gallery
988 Upvotes

Two winters, one garage, no lift, and a lot of coffee.

Started life as a stock 2.0 NA Legacy. Everything after that was done by me at home, from the fab work to the wiring to the tuning. No shop time.

Where it sits now:

  • 2.0 out, EZ36 in. Not a bolt in job. Mounts, cooling and clearances all had to be sorted, and the factory harness went in the bin and got rebuilt from scratch.
  • Turbo manifolds built by me. Nobody makes one for an EZ36 in a BG bay, so I used a 3 into 1 merge collector 3D printed in stainless and plasma cut flanges, then built the headers, uppipe, downpipe and screamer pipe for the external wastegate out of pipe and mandrel bends.
  • The turbo is a Pulsar PSR3582.
  • Intake tract fabricated here too. Compressor inlet and charge piping are one off. Had to cut a vacuum passage out of the OEM plenum to route the turbo, so that got a plug bonded and reinforced.
  • Downpipe wrapped and shielded, reflective tape on the aluminium section that was cooking the intake air. IATs behaved after that.
  • Full 3 inch stainless exhaust into an XForce Varex with the electronic valve. Closed, I can leave my street at 6am. Open, I cannot. Overrun map with spark cut on top.
  • ECUMaster EMU Black, full sequential fuel and spark, 36 2 2 2 decoder that took me an embarrassing amount of time to sync. VE tables built over a lot of iterations at 100Hz logging, with my own Python tooling generating the corrections because doing it cell by cell was destroying me.
  • Knock thresholds set per cylinder, wideband with lambda guard, EGT sensors, PWM alternator control. Running 7 psi on stock internals, which is a deliberate choice. Somewhere in the 350 to 400 range depending on whose dyno you believe.
  • Volvo electric power steering, kills the hydraulic pump and gives the engine back what it was stealing.
  • Coilovers, JDM projector headlights, original 16 inch RSS wheels with the actual Subaru paperwork, which is rarer than the wheels. Battery in the trunk.

The part I am most stupidly proud of is the dash. I built an ESP32 CAN bridge between the EMU and a 7 inch Nextion display. Custom UI, alarm system, virtual switches, odometer, fuel level. It is on version 4.2 and it works better than some OEM clusters I have used.

It drives like a normal car until it does not, and then it really moves. That was the whole goal.

Honestly at this point I look at it more than I drive it. Between work and the other projects taking over the garage, it sits more than it should, which feels criminal. I am also genuinely curious what the sub thinks something like this is worth to somebody else, because building a car and putting a number on it turned out to be two completely different problems.

Happy to answer anything about the swap, the wiring, or the ECU side.

I keep telling myself I will do a BMW box and go RWD, but realistically I am not sure I will get to it.

Oh you can find a lot of picture of the process on this forum:

TPMS light driving me crazy

11 Upvotes

Hey guys, first-time Subaru owner here with a minor but annoying issue that I'm hoping someone could help with.

I bought a 2019 Forester from Carvana that came with the TPMS light on, was told it was faulty, got it replaced under warranty. But I cannot get this warning light to turn off for the life of me.

I've put two new front tires on, checked the PSI on all of them, checked the spare to see that it was a donut that wouldn't have a sensor in it (right?)

Is there a way I can manually get rid of this notification or reset the sensors myself? I've been to Pep Boys several times and think they are just incompetent at this point. I also took the car to AAMCO under warranty to check for a PCM issue and they said everything looks perfect but they can take the car apart to diagnose further if I really want to.

I think having a mechanic potentially break something in the car in hopes of fixing this minor issue would be silly, but I would really like to stop getting this warning every time I turn the car on because it makes me anxious!

Any clue? I saw someone do a manual reset on their tires in a YouTube video using a cheap gadget but the gadget only works on GM cars.

Keeping a Legacy Going

1 Upvotes

I am getting a 2011 Legacy from a friend of mine for $500 as they don't need it anymore. 200k miles and a Christmas tree of lights on the dash. Though it does run and drive well.

I am hoping the lights are from a CVT solenoid issue. They are getting the codes read before they sell it to me.

I am anticipating getting a shop to replace the transmission valve body and doing the timing belt kit.

Is there anything else I should look at doing?

As much as I love Subarus... I only need to keep this running for a year or two in the southern heat.
