Stealership clueless after 2 weeks

Longsmith · 07-29-2019, 04:42 PM

08 335i MHD mod. I had my cabin air filter off and engine cover off for a week or so. Went to reassemble and afterwards it would turn over but not crank. Idrive was giving me every possible malfunction code. Couldn’t communicate with computer until I Messed with wiring harness and removed the air filter and covers again. Then I had a chance to clear codes and it started right up. Did this a few more times but had it towed To the dealership. It’s been 2 weeks. They replaced the DME but couldn’t communicate so they replaced the pins on wiring harness and still can’t communicate. They are just replacing shit now. Do I have to pay for all the shit they replaced that wasn’t the problem? Also side note. 2 month old OEM battery is apparently dead now too but covered under warranty. Not sure what drained it .

Yeah, dude, n54 is another forum, but I respect your pain. I once had a 335i N54, and bought a 2011 E90 M3 with no regrets. Hopefully you can too!

If you authorized the work then you have to pay for it.

would turn over but not crank? are you clarifying that the engine is not seized? no crank means the engine does not turn over. if you authorized repairs/diagnosis you are responsible for it.....

Why did you leave the engine cover and air filter off anyways? Was this outside? Hope not.
