Hello everyone,

It all started few months ago... while accelerating the glow plug started flashing and the car went into the limp mode. Apparently the fuel pressure to low... I'm thinking upsss it will cost a lot but took the car to Audi Peterborough for diagnostic and it came up with fuel pressure regulator. Ok, not that bad. got it replaced but problem still there...

Few days later I'm driving on the M11 and it happened again but this time I had lots of smoke from underneath the hood. Pulled to the side, opened the hood and I could not believe when I saw a injector return pipe being disconnected from injector and injectors holding plates ( sorry, I don't know how it is called) being lose. Tightened them, return pipe back in injector cable tied - problem solved and never came back for few months.

Last week...

Glow plug flashing, limp mode, engine management light light up... OBD Eleven and what ? EGR Valve...
I have tried to clean it but no luck...

So, I have had it removed and decoded from ECU. While doing it I thought it might be a good idea to do stage 1 at the same time...

Got the car back on Tuesday. Drives better, but... Wednesday morning glow plug flashing, limp mode again... I have scanned it with OBDELeven and lots of different codes, majority of them from Gateway, but also the fuel pressure fault came back and I had a fault P0651 - Sensor Reference Voltage B Circuit Open.
I had them deleted and the car was fine. On my way back to work I have decided to scan it again and then I've realised there is one code which it will always come back.

U10C000 - Control Module for instrument panel insert on optical data bus No Comunication

Also, P0651 came back yesterday with few other faults but they all seems to look similar as all have a codes U111300

If that is not enough today when I started the engine my left xenon went off... It came back after 1 hour drive and restarting the engine but first started flashing and the fully lighted up. I've had the xenon bulbs replaced 3 months ago so they are new.


Can anyone help me please and guide me what could be an issue ? Is this something what garage have done to the ECU ? They claiming it is a wiring problem... and they have not got anything to do with it...

Is this just a coincidence ?

Please help.

Please see the full log when P0651 occurs :

As a next thing I can say my cruise control is faulty :(... It is switching off on its own and pressing the clutch wont disengage it...
 
Also wondering if there's any water damage to a module somewhere.

Car needs a good check over.

Whereabouts are you located?
 
Hi mate, thank you for your replay.

I’m in Northamptonshire.

From what I know there was no water damage to the car.

A Remapping spec from sheffield is saying is a wrong software.

I’ve spoken to the garage and They will revert the software and will see if the codes will go away...
 
ECU remap wrong software or another module?
