first of all i will try and cover all info required for you guys to give me some feedback.
my car is a 02 1.8t AUM re-mapped by total vag
and catch can is fitted.
right first here are some VAGCOM codes.
VAG-COM Version: Release 409.1-S
Control Module Part Number: 06A 906 032 HJ
Component and/or Version: 1.8L R4/5VT 0002
Software Coding: 11500
Work Shop Code: WSC 78644
Additional Info: WAUZZZ8L021015835 AUZ7Z0A1987682
2 Faults Found:
16825 - EVAP Emission Control Sys: Incorrect Flow
P0441 - 35-10 - - - Intermittent
17535 - Fuel Trim: Bank 1 (Mult): System too Rich
P1127 - 35-00 - -
after reading up on fuel trim on the ross-tech site, i found that the MB32 readings are of some use. so here u go:
idle O2adapt 0.6%
run O2adapt -25.0%
(these should not exceed +/- 10% Apparently - being rich and + lean)
the conclusion i have come to is that its either the MAF ( as stated on ross tech site) or a boost leak causing it to run rich at elevated RPM
im quite new to this diagnostic stuff so any help is very welcome
