Hi guys, I mot'd a 54 plate bmw 318 yesterday and it failed on a slightly high co reading of around .60. the customer had a diag done which came up with low cat effieciency so he replaced the catalyst and also the lambda, brings it back to me and i leave it running for 20mins to get hot then do the test, first time round it wasnt any better and the second time I had a go it was slightly better, Going to get him to give it a proper beating before he brings it in again to make sure it is red hot. Hoping that this will do the trick. if it doesnt just wondering what should be done next to get it through?

As a worker in a responsible skilled roll within a skilled trade why am I paid so poor??

They still have all the stuff on to say they have been tested. I take it only has one lambda probe.

Got the service tech to drive it like he stole it and it got hot enough and went through. Thanks

You maybe getting confused with these BMW models,non of them should be reved to what you are saying diring the test only those revs stated in the book or on the ega database should be used.
The BMW the op is referring to will not be the one your thinking of ,even if a tech thrashed it to a inch of its death ithe bmw will never ever pass the part of the lambda test never mind the co part if it was the lean burn motor.
Take a look at the link and look at the BMW "s depending on the engine some have out of the norm lambda limits
Good point though as testers can be caught out unless the correct model is selected

Hi guys thanks for the replys, On this occasion it was a normal lambda reading beemer!!! I know about the other ones as kept failing them when we had a fleet of them coming in, Think the limit was 4.0 on the Co. This was a normal bmw. 0.2co, and it was left running for a few mins to get to operating temp but just wasnt enough, 8min road test was enough.
