Title: V6 Fault code difference
Post by: guncharmer on 08 March 2010, 14:10:40

Hello,whats the difference between the V6(cable)motronic 2.8.1 and the V6(DBW) ME 3.11 fault codes. I assume the latter is drive by wire(DBW) and seems to be related to Y26SE and Y32SE engines.So which cars/models had which and was one discontinued and replaced by the other and if so why and when.? Am just intrigued to know as currently i dont!
I can see one has 2 or 3 digit codes and one has 4 and am guessing they have different ecu`s

In around 2000 when they introduced the facelift models it changed to DBW which is indeed as you say Drive by Wire...all models before the facelift versions werent DBW (except I think the diesels)

For the petrol engines....

Later V6 engines Y26, Y32 are OBDII compliant so give the 4 digit codes.

Earlier V6 ...  2.5, 3.0 were OBD-1 so give a 2 or 3 digit code

Change happened when they went from cable to DBW ..

Not sure where the 4 pots fit in to be honest .. :)

and I know nothing about the oil burners at all .. :)

Omega V6

Started with Motronic 2.8.1, then 2.8.3.  Moved over to 3.1.x in 2001 with the introduction of 2.6/3.2


2.0 was a 2 digit code up to around 96, then 4 digit. 2.2 (petrol and diesel) was always 4 digit.

2.5TD was always 2 digit in UK
