as stated in an earlier thread (is this normal), i had my lambda changed due to bank one running rich, as well as coilpack done - when one went down... yet my exhaust emissions warning light has come back on... AGAIN. I do have some split breather pipes that are getting changed later this week, and have queried about the PCV system in the other thread. Could the fault of the PCV system/split oil breather be sending this light back on, it's coming on about a week after everytime its reset. There are no new error codes on the diagnostics, and the fact its back after having what the problem was diagnosed as fixed, its really starting to f*** me off and annoy me.
Are there any errors that have been know to occur on the 1.8T that will trigger the exhaust emissions light, but without showing up as a fault code? I'm really stuck, and don't know what to check next!
Incredible frustrated
