a friend bought (as is) 1996 C280 which has the following problems:

1- ASR, ABS lights always ON when engine is on. although car does NOT go into limp mode and both systems are working.

2- Speedometer won't work.

3- Odometer frozen at certin milage.

the dealer told him it is a faulty ASR control Module. so he bought a used one for $500 and nothing changed.

any idea??????
