So, I took my truck in today for the ever persistent P20EE. They completely screwed up and didn't even acknowledge the new TSB released last week:
I got a copy of the technician's sheet and he completely misdiagnosed it. I am calling them tomorrow so they can get the SCR catalyst ordered for me, this is getting ridiculous. Here are the mechanic's notes:
-Performed diagnostic and testing DTC P20EE-00-SCR NOX
-Test DEF System for leak
-Tested Quality DEF - concentration by spectrometer
-Tested DEF System, injector and pump for fluid quantity test (removed injector and measured volume DEF (29ml, OK)
-Performed SCR healing procedure (stationary DESOT and highway driving over 55mph)
-Retested for DTC. No DTC this time.
-After test DEF refill DEF tank 5 GAL. DEF
So essentially, all they did was clear the code and test the DEF system (which passed). According to the TSB they should have replaced the SCR catalyst if the DEF system checked out. Why the hell would they not apply the TSB? I am starting to get fed up with this dealership's service department.
To top it off, my service advisor forgot to tell me my car was ready, so I called in at 5:30 (after he'd left) and they said it was all set and said he should have called me. And to top that off
They wanted to charge me $50 for the 5 gal of DEF (which they never called to have me OK). I told them to pound sand and that I didn't authorize the work. Threatened to call the cops if they didn't give me my keys, and that got them moving
If you live in MA, AVOID Central Jeep for service. I'll be going elsewhere from now on, even though they are 10 mins away.
