Fault code P2029-002, running rich
Hello all, I am experiencing some fault codes related to the engine running rich. When i first start the engine it is shaking and the rpm drop below 900 and lots of smoke is coming out of the exhaust (smells like gasoline and sometimes black smoke) Fault codes:
P2029-002 1/2 State: Historic Self-adaptation of mixture formation at lean stop(Tendency of engine towards rich)
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
P2061-002 2/2 State: Historic Alternator serial interface, Mechanical fault
The exhaust is giving lots of smoke even when it is warmed up, it smells only gasoline and the fuel consumption is quite unusual. I am attaching some photos of the o2 sensors within my diagnostic tool. These values are after starting up the engine and the coolant is approximately 40 degrees Celsius. I am also experiencing a P2061-002 code related to the alternator, it only appears if I turn really sharp for example like parking, it only appears for 10 seconds and then disappears. The engine is charged correctly and I do not experience voltage drops. What can be the reason for these problems? Is it the o2 sensors or the lines under the air filter box? Please help as I need to fix it for my MOT.
