Hey Everyone,

Newbie here, loved the Crossfire for years so went and got a very well looked after 2005 V6 a few weeks back. One of the best looking inside and out that I had seen.

Three weeks in and I had been driving about an hour, went over a bump and all the lights came on and the car lost power. Managed to get it into a lay-by, wouldn't start but when the key was turned every light came on, heating, radio etc and the fan every now and then would go super fast. After an hour or so it cooled down and started again but when recovery came and i drove it onto the trailer it died again.

I had no warning lights and still don't, there was no bang or anything noticeable out of place, no smoke or smells.

Got the car back today and had diagnostics done on it, not many garages work on these cars now a days so I am doing as much research as I can to see if its something that I can work on from home.

Car started up fine again this morning, no warning lights etc, I did not drive it though as I am worried whatever the issue is will still be there and it will breakdown, the diagnostics seemed first good step.

Error codes were:

IC- 1040-0000 No CAN comms with PCN
ESP - 1178-400 / 1174-400 / 1038-274 / 1022-274
TMC - 2311 - P0600 Engine can message missing
TMC - 2312 - P0600 engine cam message missing

I have seen some mentions of similar issues saying it could be the RCM needs re-soldering, am basically here for the pros as from the looks of the forum you lot know more than the garages....

Any help would be massively appreciated

Also just to add, checked all fuses (all ok), battery connections are solid and no movement, fan belt fine, yes it had a tank of fuel and coolant and no leaks of any sorts. Also I think going over the bump loosened something maybe,

Thanks in advance - all I want to do is drive her
