Lit up like an Xmas tree - transfailsafe

[chilliwilli]

Just picked up the X from Park Ave BMW in Maywood NJ. Per SA, water pump, valley pan and battery were replaced...fault memory was cleared, she was test driven and all systems are a go. Well, not even 15 minutes after my departure, the SES light re-appeared. What could this possibly mean?

Had it not been for an engagement i was committed to, i would've turned right back around to drop her off. I will drop off first thing Monday morning...and they better not even consider charging me a penny or it's on like donkey kong!

They shouldn't give you any problems when you bring it back, most of us stand fully behind our work. The only way they could try charging you is if it is a fully unrelated problem, and just happened with bad timing. But from the sounds of it, likely not.

Crossing my fingers and toes ...

On another note...was going to do some detailing today including lightly washing and wiping engine components. Should i stay clear until SES warning is diagnosed?

I don't see where that would hurt anything. Even if they ask about it you just tell them you washed it down after the light came back on so it is unrelated to that.

I'd be curious as to what faults were stored when you had it in the dealer a month ago, when you spent $4k. You could call the dealer and have them fax you a copy of the diagnosis report, then you would not only know every fault that was stored in the vehicle, but also what the tech did when in tester diagnosis.

The indy reviewed my service invoice and says the dealer did zero to address the "trans failsafe" issue. It seems they addressed other matters but not the main issue. The faults the indy is pulling are for MAF and transmission control module (EGS). Any thoughts? I'll post the fault codes when the indy sends to me.

Does that dealer know what they're doing?! I love it when you take it in for a rough idle and they say $4K later ... your transmission has now been rebuilt! I'd be in their face like .. like ... ayayai!

Dealer just called and said they shred all diagnostic records when cars are picked up. How convenient ...however, here are the codes the indy is pulling with their scanner. It's not the OBDII...

- (048)30 Converter lockup clutch excessive slip
- (002)02 Pressure actuator II

They're gonna do a full diagnostic and circle back tomorrow.

So it seems the following are potential culprits that "may" need replacement:

-Torque Converter
-EGS
-MAF

Tech said she hasn't been driven hard so the trany "may" be ok but one or possibly all of the above "may" have to go. For those of you that care i'll update.

So after a thorough diagnosis and a number of test drives, they were unable pinpoint the source of the trans failsafe warning. They checked fluids and internal components and all seems fine

However, there was an issue with the MAF so it was replaced. The MAF issue started with the stealer...they left the MAF loosely connected after service... ...I found out after a 4 hour trip to Boston, when i checked under the hood for a mysterious whistling sound. One of the MANY reasons i'll never return to the stealer unless i buy a new model. Anyhow, they performed a final test drive when dropping her off at my parking garage and still couldn't replicate the trans failsafe issue. They suggested i monitor and communicate any odd behaviors.
