i have a problem with my co% being .6 too high for german standards the lambda and the oxygen pump has been changed can someone help me please as i need to get it through its roadworthyness test
|
Once again; a perfectly sound oxygen sensor bites the dust. Have the fault codes been read and all the sensor readings checked - particularly the coolant temp?
What's the engine code on this one? Was this tested at idle or higher revs?

thanks for replying screwloose, the test consisted of an idle test and at higher revs the engine code i have found out is ape with german garages i dont think they have machines which have codes as the mechanic took 2 days trying to find out what the problem was and the temperature on the test sheet was 60 degrees if that makes any difference i hope you will be able to help me on this one as the car is costing me more and more without any change
cheers

Getting the codes read is the essential first step and nothing should have been changed until that had been done. That's virtually fraud.
If the garage hasn't got a code-reader, then they are not competent to work on modern cars - take it to one that has.
The temp on the test sheet would likely be the oil temp.
