the asr light comes on after 3 mins from starting
i have a bosch kts 300 diag kit which has thrown out code 21.this ,i think refers to air cell pressure
(faulty pressure switch).the car does not go into limp home but the light remains on. could any body
point out where this pressure switch hides away.
thanks in desperation .[:(]hammy
