Had these 2 pop up on Golf 1.8T, car has been very jerky when cold...

17705 - Pressure Drop between Turbo and Throttle Valve (check D.V.!)
P1297 - 35-10 - - - Intermittent


17545 - Fuel Trim: Bank 1 (Add): System too Rich
P1137 - 35-10 - - - Intermittent


I guess the 1st one is referring to a split hose etc? Although i have looked and cant see anything??

I would suspect the MAF sensor for faults like that. Especially if you can't find any split hoeses.

Its probably reading the air flow incorrectly, causing too much fuel to be injected and the lambdas to read the rich A/F mixture.

I would try and clean it first, clear the codes and see how it runs then...

Sounds like a plan, cheers mate.
