Exhaust warning light - update: problems! - RESOLVED!

(1/6) > >>

stealthwolf:
Managed to get the warning light for the exhaust come up today for the first time. Car's been fine, with no unusual changes in the last few days or so. It didn't come up this morning when I went to work but came on an hour later when I had to go somewhere else.

No obvious changes in the characteristics of the car.

Sooo....did a VCDS scan (posting just the relevant bits):

Looking these up alludes to problems with either the fuel pressure sensor itself or the pump (or both!).

Anyone had a similar problem come up? How long did it take to sort?

bacillus:
Have you had your the fuel pressure sensor changed?

btw you should update your vcds to the release dated 11-09-09

stealthwolf:
Nope. Other than an air filter change, car has been unmolested since I bought it 12 months ago.

JPC:
Not remapped either?

bacillus:
I think you need to get the fuel pressure sensor changed in the first instance if you don't want to use the dealer for whatever reason.
