EPC light is on :( Help please

Post by BruceBanner » Mon Oct 08, 2012 6:32 pm

Hi,

Drove to Walsall last week parked up all was fine. Came to start up an hour later and noticed an orange light 'EPC' remained illuminated.

So drove half a mile stopped, switched off waited about 30 seconds and restarted, but light still on. But the car was driving and behaving normally? Later an engine shape in yellow also came on.

Next day took it to my local mechanic who plugged in his diagnostics, it stated : Ecu checksum error. He cleared it but it came back as soon you switched the car off and then back on again :thumbsdown:

So took it in to Halesowen Audi today. Came up with same thing. They said there are 2 ECUs and BOTH Need replacing, at a cost of nearly £1500 :x. The service guy said its probably to do with the remap, so taking it back to Doug as soon as I get a chance. But did explain I had the remap about 18 Months ago and all has been fine.

As well as this, my drivers light has been flickering and the going off for a while now (resulting in a bulb shape with a cross through it appearing in the DIS)so had that looked at also - put down to the bulb needs replacing. So any bulb suggestions would also be welcome!

Any one had or heard of a similar problem? Your feedback would be much appreciated.


Thanks :biggrin3:

Thanks mate, any info would be appreciated. I don't fancy shelling out 1500 quid!

Also hoping Doug can sort it, if any one can he should be able too!!

I doubt both ECU's would need replacing - must be something else surely.
Keep us updated pal
Gone but not forgotten boohoo !!!
