Total System Crash!

[Muggle]

My apologies in advance, because this post is a bit of a marathon.

 

For the last few years my car, a 2006 2.0L C5 Exclusive, when it is cold like now, sometimes warns me that there is a DPF problem or my steering system isn't working, but I've always treated them as random notifications, because of 1. the general reputation of french car electronics 2. because if I turn the ignition off and start again, all is fine and 3. because they never happen when the weather warms up.  

 

However, I was coming home 3 nights ago when everything on my car just died (cruising in a 50mph zone, no acceleration). It was a bit hairy in total dark with no lights, apart from on the dash, because the driving lights (set to auto) died at the same instant. When I had pulled in to the side, I tried the lights manually and they worked fine.  I gave it a few moments, turned the key and everything was perfect again.

 

I was around 5 miles from home, so I drove off a bit warily and a few miles later it happened again - I was about a mile from home now. This time it wouldn't start at all. I called the breakdown to tow me home, but cancelled it 30 minutes later because I had tried the key again and the engine started as normal - no errors on the dash display.

 

So, this being a technical matter, I took it to a local KwikFit and let the Mastertech play with it for a day. He couldn't locate a particular part that needed replacing, but gave me a whole list of fault codes and said they pointed to a BSI meltdown and that I needed a new BSI at around £900. It was beyond his skill set, so I took the car home.

 

Now, when the engine is started, it still runs fine, but the engine amber light is on, as is the anti-skid light, plus the following dash messages:

'Speed control system faulty',

'ESP/ASR system faulty'

'Depolution system faulty'

 

This is the list of codes the Mastertech gave me:

U1208 - engine speed info value received incorrect

U2006 - no engine speed info

U2005 - no vehicle speed info

U1213 - vehicle speed info value receive incorrect

U1105 - no com, steering wheel angle sensor/no signal

U1205 - steering angle

U1208 - data invalid engine ECU value received incorrect

U1113 - no com with ABS no signal

B`932 - PDC

U3905 - aux

P0336 - engine speed coherence

 

Can anyone help me or is it time to look for a my next car?

Odd electrical problems are sometimes due to a low battery voltage. Without the engine running you should measure about 12.5 to 12.7 volts.

 

Cutting out when the engine warms up could be a faulty crank shaft sensor.

 

I think the steering angle sensor is built in to the comms 2000 switch unit under the steering wheel - if this is faulty it would also affect the esp/asr.

 

The vehicle speed probably comes from one of the abs sensors so maybe there is a problem with one of these.

 

Depollution system can refer to anything related to engine emmisions and not necessarily the dpf.
