Stomp Test?

[Wschnitz]

I've figured my check lights been on long enough and that i should do this "stomp test" for engine codes. But how do you do it? I looked in both engine sub forums and general technically and cant find it. I may just be dumb, but if someone could kindly help me I'd be grateful.

So if your car is an 87 do you need to have a dealer check or what?

Only the 173 DME (and later) as found on 1988 and later 325i/is/ic cars support the stomp test. Prior to that a diagnostic system is required to recover fault codes from the DME. On the cars that support the stomp test, the idle and WOT switches in the TPS must be working.
