I posted on OhioVW.com for anyone local with a VAG-COM and found someone... He came by yesterday and pulled the codes from my TT. My CEL was on, so he pulled the codes, cleared the CEL and pulled them again... the CEL is still off as of now, but here is what I'm getting... ( deleted the parts with no faults)

So, that all stayed clear, or is there something there you need help with?

 

More or Less, I was just looking for any ideas as to which part this might be? Could it be something really small?

2 Faults Found:
01279 - Longitudinal Acceleration Sensor (G251)
27-00 - Implausible Signal
01279 - Longitudinal Acceleration Sensor (G251)
57-00 - Electric Circuit Failure

 

and no, the CEL is still not on... but I do have the codes listed, dispite it's not being on

 

None of those codes will trigger a cel. As for the abs code, it sounds like a possible sensor failure. Not very common but ive seen it a couple times. I would clear it and see if it comes back. With the hvac code, i would run basic settings 1 and 2. If they run ok i would worry about it. There probably isnt a problem with the system. As for the central locking code, its probably an alarm triggered by one of the interior monitoring sensors. Personally none of those codes are serious and most of them can come up when there is nothing wrong with the vehicle. I would clear them all and look into them further if they return.

 

Is that something that is run from the VAG-COM?

Actually, I think its bigger than that. No matter if the car is locked (from key fob or buttons inside the car) or if the alarm is even on, the passenger door opens right up. It still sets the alarm off (75% of the time) but the passenger door does not lock.

Probably something only the dealer is going to be able to look at, huh?
