Are they not able to tell you if emissions components related to the EGR system are covered under emissions warranty?


There are so many components it is almost impossible to troubleshoot the emissions system without dealer software, and even then a lot of times they throw parts at it - it should be easy to explain to a service advisor that you are throwing codes for the EGR system, its not a glow plug for example. Alternatively, find a good independent BMW diesel mechanic/shop. However, P codes tell next to nothing and you really need to run dealer level troubleshooting software (ISTA+P? I believe) as they will have test plans for the codes thrown in order to pinpoint the failing component. The EGR at the front of the engine and the EGR cooler is easy to get to if those components are failing, but again, throwing parts at it is a crap shoot - and emissions components are NOT inexpensive.


Do you live in a free state that doesn't have emissions testing for diesels? I see you're in Maryland so its doubtful. Thankfully we do, once something fails in the emissions system that is not covered under warranty, my wifes will be getting full deletes and amended tune to match.
