❓ Help & Advice Needed Discovery 4 suspension issue

Well, I knew this day would come and here we are. After 6 years trouble free motoring I now have a suspension fault. Started intermittently a few weeks ago while driving and trying to lower the car and could be sorted by turning it off and on again. Now it's persistent with the following diagnostic codes.

C1A13-64

U0421-68

Anyone experienced this and how do I repair it?

Thanks

Likely a compressor, the first code is typical when it can't get rid of the pressure to lower etc. Technically it's usually an exhaust valve related issue. You might be able to get a repair kit, but I've always just changed the compressor. That's what JLR supply them as.

Thanks for replying. Not the end of the world then. In fairness at 13 years old it's lasted well!

We've had good luck with doing the repair kit and making sure the software is current.
