I had a bad battery and took the 335i to the dealership. They replaced the battery (2 trips and I had to take it to autozone to have it tested to prove it them). I drove the car about 200 miles home and lost power on the way home. The engine ran but it was really down on power and I had to keep it in a lower gear.

I pulled over and killed the car about 50 miles later and restarted it and things returned to normal. This is one of the codes that I pulled using the Bavarian:

29DC:
29DC Cylinder injection switch-off
Error will cause a warning light
Error is not currently present
Test conditions have not been completed
Short circuit or signal interruption

The car has a dinan stage II and cat back on it. It does not feel the same. A little weak and has some lag to it.

Thoughts? Anyone else had something like that happen to them?

29DC:
29DC Cylinder injection switch-off
Error will cause a warning light
Error is not currently present
Test conditions have not been completed
Short circuit or signal interruption
EXPLANATION: Fuel pump code
FIX: Normally requires fuel pump replacement

Well, I guess that answers it. Now getting the dealership to do it. I wonder if the dealer will have to reflash the ECU leading to the Dinan software have to be reflashed?

Called Dinan and the dealership. I am taking the car in next week. If they replace the HPFP the software on the ecu will be updated which means taking a 500 mile trip to update the Dinan tune.
