Right, I'll go through this one from the top, from day one of ownership.
Sunday (in October), Picked up car, 53 plate Black Signum 2.0T Elite, full spec with literally almost every extra fitted to it (electric everything+Nav etc). 76k miles, full history (main dealer bar the last oil service @76k), non factory but reputable LPG conversion (BRC) fitted by a well known installer in Manchester.
Monday (next day) wife takes it to work, steering wheel light and traction control light come on, so she brings it back for me to look at, but I can't find any problems after restarting it. Drives faultless either way.
After a while, maybe two weeks, the same happens again, so I get the car booked in for a Tech 2 at a VX specialist in Nottinghamshire, 21 fault codes stored (xenon levellers, steering angle sensor, misfire, low fuel, low battery all the usual crap really) so I got a full reset done and was told if it happens again its more than likely the CIM, assuming the car drives ok when its all lit up like christmas.
Over the next 2 months or so, the traction control light, steering light and loss of speedo happen occasionally, until just after Christmas, the whole dash starts to go nuts, ABS, TC, Battery, Fuel lights all start flashing, rev counter, fuel gauge and speedo start going wild, but the car still drives perfect (on petrol or gas, that doesn't seem to affect it).
Eventually, just before we had the car booked in for another test, wife goes to work, and the car won't start, just nothing when the key is turned, ignition comes on but no starter click or anything. After constant switching on and off repeatedly, it finally starts, and carries on starting and driving as normal (but dash lights and clocks still going nuts). But the same eventually happened, managed to get started and drove to VX specialist.
So this friday (yesterday 27th Jan) get a new CIM module from VX main dealer (GL code on the original, DL code on the new one - apparently this is the new up-issued part for my car, and the parts guy did show me on the screen "services GL/GN code") and had it fitted by the same VX specialist, full tech 2 reset and code of both keys etc. On the way home after all work is complete and tech 2 carried out, traction control light and steering light come on, so take the car back.
After another tech 2 test, steering angle sensor showing at fault, so this is re-calibrated to clear and reset the codes and sensor.
After 24 hours, we get the traction control light and the steering light again, shortly followed by the dash lights and clocks going mental just as they did before the new CIM was fitted.
So basically, I'm nearly £300 out of pocket with the same fault, so has anyone got any ideas or advice I can have, as the cars going back in on monday for more investigation, but I'd like to know what I'm looking at here, we've only just really got the car and both love it, so I'd really like to get it fixed properly. Any help would be appreciated greatly.
Cheers all!!! Rob
