Hi All,
Been enjoying my 535D for a while now but have 3 issues that started on the car.

First I am getting an error in INPA about rough control idle.
4B10 rough controller

So I check the injectors and actual/nominal values which are below.

Injector Cold Idle

2500rpm (Air Mass looks wrong)

The idle is rough on the car and in extreme cases the engine will vibrate enough that a passenger would notice.
The car appears to drive fine apart from at random times it will slowly build up speed, and others it will kick forward rapidly.

Secondly...
The "pressure converter" listed here as number 1 that drives the turbo waste gate, its at the very back of the engine.

When i stop the engine you can hear this converter clicking rapidly, if you touch it you can feel it vibrating.
I got a new one and also check the vacuum hoses again (there new silicon ones) and also verified the wastegate it controls is working correctly and not stuck.
BUT the noise still remains and its not after every drive, but about 70% of the time it happens.

Thirdly

A46B No LVDS Signal

This error is constantly on even after a reset, I have no apparent issues from this one but would like to get it cleared.

And this one (Info Error)

41ED cyclic Authentification

Again not a clue what this is, but is also won't clear.


Has anyone got or had these problems, I think it affecting the car as sometimes the lift is erratic, it builds up slowly sometimes, and then other times it just accelerates rapidly.

Thanks In Advance,
Mark

Anyone any advice?

Thanks

Hi Everyone,
Has anyone any clue about the errors above?

Thanks.

Still have got no where with these issues.

Hello mate, Have you had any joy on this?

I have the rough idle fault showing and same passenger 'noticing' symptom. I have posted on this and another forum - one chap said to check the vac pipes on the engine mounts....

Greetings,

I got a 535D with the same symptoms! Does anyone have any updates on this issue or any recommendations of what it could be?
