Just an idea, but have you checked your throttle body? Usually it will throw codes if it's not aligned correctly, but sometimes if the battery dies the throttle body can lose it's place. The throttle body is in charge of air flow, so if it's not letting any air in the chambers, that could cause it to not start.

Thank you so much for commenting on this thread! I really really appreciate it!! He DOES use an OBD-II tool. But if you think about it, since it's a compression issue, do you really think there's a code that there's a code to just tell you what needs replaced to fix a compression issue? I feel like that's a problem that the sensors can't really pick up on... but what do I know x_x

He replaced the plugs and it would not start. It was doing the same exact thing as it was before he had replaced the plugs: engine would crank, you could hear it, but it would not fire. The car would not start.

Jenn, see if this sounds right. The car was running. You left the dome light on and drained the battery. The transmission felt like it was slipping. The car wouldn't start. Those are the symptoms? Right? Somehow your mechanic thinks the cause of this is a stretched timing belt and loose tensioner and spark plugs? I repeat, find a new mechanic.

I will TOTALLY relay the idea to him and let you know what he says. I am so anxious about this entire situation. I love my car to death!!!

): I'll definitely consider the idea... do you have any idea what it could be?

soulstep is on the right track. BUT, the mechanic must VAG-COM it to know for sure. the car's computer will tell him OBD-II may/probably will not. If he can't VAG-COM it then seriously you need to find a mechanic who can. Good luck.

I believe you need VAG-COM to correctly do a throttle body alignment anyway. If you don't know anyone with a VAG-COM, try reading through this article and see if any of the posters have one near you. https://www.audiforums.com/forum/vag...ag-com-140752/

Oh thank you!!! I appreciate your suggestions!

Haha thanks so much!!
