Title: only just bought my mk4 gti 2.0 and engine/exhaust warning lamp is on already.
Post by: marmalade86 on 12 April 2011, 22:42

Hi hope someone has a few ideas or suggestions.
as the subject says iv got the engine/exhaust warning light on after only driving around for 2 days.
the exhaust seems in good nick to the naked eye and sounds normal.
the engine dos not have any obvious leaks or funny noises either, i may have put slightly too much oil in but not excessive as it was coming up the dipstick.
but i would imagine that the oil pressure lamp would come on for that not engine management.

its been suggested that it may just be due for a service but im not sure.

again any help would be great

Could be a Lambda issue but you need to get it scanned for fault codes as a 1st step.

Had my baby checked out and you were right the lambda sensor had completely stopped,so was drinking petrol like it was pop!!

unfortunatley the garage cracked some water bottle or something with a spanner so its had to stay in overnight to wait for a part.
good call tho
 :cool:
