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 .[:(]

ASR light

Sounds like the problem my car had (same code)- does your asr/abs pump (left front of engine compartment) run constantly until your light comes on? I had to replace the pump/hydraulic unit as the old one had an internal leak and would not build pressure, causing the faulty pressure sensor code. New one is some ungodly price (~$3500 CDN) but thankfully I found a used (and hopfully good) unit.
