Engine Managemt Light On, Won't Change Up Into Top Gear

[dalboy]

I have a 2001 2.3 V6 auto. The engine mamagement light has been on for a while now, even after service and 3 auto electricians. It will not go into top and drives in 3rd gear. Still drives well but obviously drinks petrol.

It has been cleared by gearbox specialist and for short time worked, discounting a gearbox problem. However the light returns and so does the problem. The fuses have been checked, new battery and new alternator fitted.

Don't want to throw good money into a car work abt £1K.

 

 

Any ideas please otherwise it is the scrappy.

 

Thanks

check all the coils are ok a missfire causes a colleration (timming) problem with autobox. If the bonnet is badly fitted on the vr6 24v rain water goes down coils and shortens there life.

 

most problems are easily deduced using vagcom do a forum search & buy a lead.

_{Brake Light switch has also known to be a culprit. I believe it utilises two electrical tracks and has been known to impact on the engine management system and subsequently the gearbox getting incorrect signals from the ECU.}
