In my ever continuing hunt for an odd fault on my 1.4 petrol I've finally managed to get the following fault code using VCDS lite:
>>>>>>
Control Module Part Number: 036 906 034 Q
Component and/or Version: MARELLI 4LV 3720
Software Coding: 00051
Work Shop Code: WSC 02138
Additional Info: WAUZZZ8ZZ1N034323 AUZ7Z0Y1669105
1 Fault Found:
17961 - Barometric / Manifold Pressure Signals: Implausible Correlation
P1553 - 35-10 - - - Intermittent
>>>>>>
The issue I have is that when the engine is warmed up a bit, driving with light load the EPC comes on and most of the times also anti-skid and ABS fault. Previously it hasn't recorded any fault codes on the engine, only ABS, but I finally caught the above. I never get any faults when chugging along at motorway speeds.
Done so far:
Cleaned and adapted the throttle.
Replaced the Lambda control probe.
Checked the function of the cannister valve.
Checked spark plugs.
Cleaned the EGR valve.
Is there a pressure sensor on the intake and if so, where is it located?
Any ideas are most welcome, the garage is booked for the next few weeks so there's time to fiddle...
