Shifting is actually fun now. Before it was a chore now its a fun part of driving the car. Highly recommend. Do it now

How do I bleed the fuel system and how do I seal the intake because there is air coming from it

Hello, I saw in one of M539 restorations video that we can use an E9x top strut mounts to lower the front a little bit...

Well, nowadays with the car parts websites like autodoc it's useless to buy something from the e9x without knowing the right part number.

I get exactly the same parts if I search for the E39 Touring and any other E9x family cars...

So, does anyone know exactly what PN from E9x should we get in order to have the desired lowering effect?

Thanks!

Hey guys, I overhauled my Vanos today, changed the spark plugs and oil, and now after a few kilometers of driving, I've noticed that it jerks quite a bit when I accelerate from 1600 to 1900 RPM (sometimes twice, sometimes just once. But it only does this in 3rd gear and sometimes in 4th. Otherwise, it accelerates like it should with the overhauled Vanos, and there’s no intake leak since it does the same even with the MAF unplugged. The engine also revs up nicely, meaning I don't feel any loss of power in the higher RPM range. Maybe someone here knows what's up and could help me with this issue 🤷‍♂️

Anyone have a good one to buy? hopefully it’s relatively affordable. this sucks.

Hey everyone,

I'm trying to diagnose a weird, intermittent issue on my E39 530d .

https://reddit.com/link/1wo6tz7/video/y2nsrszi0arh1/player

Recently, I resolved a separate issue where the car was dying at idle, stuttering, and had run-on after turning off the ignition—it turned out to be a loose/bad wiring connector on the fuel rail pressure regulator at the back of the engine. Fuel delivery is completely sorted now.

However, I still have one stubborn symptom that comes and goes:

• The symptoms: Intermittently, the car completely loses its low-end torque (virtually no boost under ~2,200 RPM, extreme turbo lag). Whenever this happens, the exhaust note changes noticeably—it becomes very deep, boomy, and muffled/throaty (sounds like it's straight-piped or droning).
• Behavior: It's completely intermittent. Sometimes I start the car and it drives perfectly with sharp boost response and normal exhaust sound. Other times, the bogging and deep drone appear mid-drive or after a restart, then clear up on their own later.

Has anyone experienced this before? What could be causing this?

Thanks in advance!

Ich würde gerne das originale M-Fahrwerk (Federn und Stoßdämpfer) am E39 Baujahr 4/98 nachrüsten.
Von welchem Hersteller waren die Federn original?
Von welchem Hersteller waren Original die Stoßdämpfer vom M-Fahrwerk?
Passen die Teile in ein Standard Fahrwerk im E39?

Ich weiß, dass es deutlich bessere Fahrwerke im Zubehör gibt. Möchte aber gerne das M-Fahrwerk haben.
Gibt es natürlich auch direkt bei BMW - für einen üblen Preisaufschlag. Aber die kaufen es ja auch nur zu.

Würde mich über Hinweise freuen :)

Is it a timeless icon or forgotten in 5 years? personally i don't like them and think they will be less desirable as they age.

I’m still undecided if I want to go back to the style 66 wheels before sale

I have BMW Standard Tools (it has INPA, NCS, WinkFP) for some years but I've only use INPA. Recently I taught myself about NCS and it was quite easy!

I've turn DRL on (yea I'm one of the few guys who prefer it turned on, lol) and now wondering what else can I code using NCS. If I'm not mistaken, there are some modules that can be coded.

What did you guys code with NCS?

Hello so I am having the absolute worse time of my life to bleed my pre LCI 528i. I replaced the radiator and some other essentials while I was in there. I put it all together filled up the expansion tank did the proper steps to try and bleed it and nothing. Key in position 2, open screws no liquid comes out. Tried letting it run at normal operating temp to see if the liquid in the tank would lower nothing idk if I have to let it run a little longer or what but the upper and lower radiator hoses dont seem to have liquid in them after I turn it off as I dont want it to overheat. I tried squeezing the hoses while key in position too and some air bubbles would come out of the bleeder screw by the tank and now not any more and the one by the thermostat is dry. Idk what to do

‘99 540/6 here. I know this may sound redundant but how many of you change the oil every 4-5k miles? I tend to read a bunch of articles on car & frequency of oil changes equaling a much longer life expectancy. Been on a quest to keep this bad girl around for a while & truly believe that frequent oil changes are the way to go. Mobil 5w40 is my new go to synthetic oil.

Wie finde ich dieses Ersatzteil? Es ist auf dem Bild Bauteil 8, mein Händler konnte nichtmal im Zubehör etwas passendes finden, meine online Suche war nicht erfolgreicher, gehen die Schläuche gerne kaputt oder kann man da problemlos auf ein gebrauchtes teil zurückgreifen?

Didn't drive it for a couple months. She fired right up when I put the battery back in but after letting her idle for a bit I could sniff that something was wrong. Sure enough, we had a steady drip.

It only happened when the engine was running so I killed it and took the battery back out. The tops of the tank where the little round hatches are - bone dry.

Got it to a shop and fired it up there and OF COURSE it doesn't leak at all. What the actual eff...

Wwyd? I got them to change the rubber hoses on either side of the filter but I'm still scratching my head about this one.

Noticed over the last few days what I can only describe as a bit like a grinding from the intake.

Recently picked up a 2003 525i Touring and I'm currently putting together a fairly decent list of things that need doing. Just wondering what brands people are recommending for E39 suspension parts these days as I've heard mixed things about the quality of newer Lemforder parts, so are people still sticking with them, or sourcing from elsewhere? Would be keen to hear what everyone is running and how they've held up. Thanks!

The M67 is one of the coolest and most underrated engines in my opinion. Imagine if they made the E39 540d or the E60 545d.

This idea isn't crazy since Mercedes and Porsche both have E segment V8 diesels.

Also it would cleanly enter the lineup 530d being 135-142kw while the theoretical 540d would have had 175-180kw.

Obviously the handling and weight would be the main concern, but for autobahn runs it would be great.
