In January I took my 05 sport diesel in for the Transmission and TC flash. Dealer burned the ECU unit I think? Said I needed a new one?? I have been waiting for a replacement part. In the meantime the milage has gone south and the battery will be dead after two days. Check engine light stays on. Get lots of black smoke out the tail pipe. The dealer said it was OK to drive the Jeep. Anyone have any problems like this? Any suggestions would be appreciated.
This has been a problem on '05 CRD's. when they get the new TCM it most likely won't take the new flash. They used another customer's '06 CRD as a host to clone the TCM for mine.
Keep an eye on your oil consumption as the excess black smoke is likely caused by sucking oil through the air intake. This causes a chain of events that plus-up the works. You may want to look at the MAP sensor in the intake manifold for excess carbon build-up. I would also assume you have a CEL with the excess black smoke, possibly for EGR function?
