help! My engine check light always on!
Audi A4,1999
Engine check light is on!
I get the code from AutoZone
it says:
Troubshooting P1858
Transmission transfer case contact plate 'c'
short circuit to ground
Transmission transfer case contact plate 'D'
Open circuit
Also Troubshooting P01102
The PCM determined that the mass air flow input is lower than expected for the current engine operating conditions.
Coud anybody tell me what is the real problem? is it serious? How can I fix these problems?
Thanks a lot!
