So i got a code on vagcom..17536 p1128 system too lean..and limp mode..car has 160 000 kilometers and i belive o2 sensors are never changed
17536/P1128/004392 - Fuel Trim; Bank 1 (Mult): System too Lean
Possible Symptoms
Malfunction Indicator Light (MIL) active
Possible Causes
Mass Air Flow (MAF) Sensor faulty
Oxygen Sensor Control faulty
Oxygen Sensor(s) faulty
Fuel Injector(s) faulty
Possible Solutions
Check Mass Air Flow (MAF) Sensor
Check Oxygen Sensor Control
Check Oxygen Sensor(s)
Check Fuel Injector(s)
It seems that there is no vac leak as gauge is showing -0.8 bar vac. Gauge is connected on a t piece between DV and intake mannifold.
MAF also seems ok..reading around 3.5 g on idle..and 148g on redline.(used to be 153 though)
I checked block 032 and i thing there my problem so i just need confirmation..
Both lambda values were 0%...for 5 min, or 10...then i started to drive and it changed to 0.9 and 0.6%...then, after 5 mins of driving it changed to -2.1 % and 11.7%..
So those values change very slowly..every 5 mins..and i read that it doesnt supose to do over 2%...
Would all this mean that my front O2 sensor is dead?
I also noticed that my coolant temp cant get over 85 celsius...and i also noticed droping even more while going fast..like 75 celsius...
