CIM failure?

[richcc]

Hi there looking for a bit of help or advice with regards to a 2.2L 2004 Vauxhall Signum.

Basically the car drives great apart from an intermittent electronics fault. This happens sometimes when driving or more commonly when the car is parked up and switched off.

Basically when driving the problem presents by a big fat spanner service signal presenting in the centre of the dash and then ABS, battery and engine warning lights all come on very quickly followed by all lights (in odometer) going out and losing all the dash instruments, indicator stalks, windscreen wipers etc from the column.

The car will continue to drive with no loss of power to the engine. As soon as you stop the car you can't then restart as the ignition signal is not being accepted. The car will then sit for 2-12 hours and then work again. Sometime the same error occurs (without the warning lights of course) and the car simply will not start in the first place. Obviously a massive pain, so did some research and found it was likely to be the CIM unit that was failing so have taken to Vauxhall to confirm which they now have.

There diagnosis was new CIM as a start and then inspect further to ensure problem was solved, however this was for a pretty large sum of money and frankly with other work I need to complete completely uneconomical.

Basically I was wondering on the off chance that anyone out there had a cheaper solution to maybe try prior to selling for parts or whether its best to get rid and get a new car. Or whether maybe someone could give me some pointers to replace the unit myself and find a kind soul who could recode when into the car (as I believe it won;'t just slot in and work).

Thanks

Even if it is the CIM at fault, you can pick up a tech2 cleared one for about £40 ish.. Someone would probably charge about £40-£60 to fit and program it in using your original keys

Thanks for the help guys, Dom will take a look at the abs plug tomorrow and see if that helps. If not will definitely get in touch about replacing the unit as sounds like can be done a lot cheaper than the garage quoted me!!
