Hello everyone,

So, I went to leave work this evening and my 2006 A4 2.0T Quattro wouldn't start. The starter was turning over as expected, but there was no ignition. Given that the starter was going and the electronics were working, I would guess it's not a battery issue. Are there any known issues I should be aware of? Does anyone have any tips or recommendations on other things to check before I have it towed to the shop? Unfortunately, my warranty expired 2000 miles ago. D'oh!

Thank you in advance for any help you can provide!

Dont have a clue w/o being there or having codes, but, if it turns out to be a big ticket item, you just might get AoA to at least split the cost since its just out of warranty.

 

Hey Jim,

Thanks for the tip. It certainly doesn't hurt to ask them to help pay for it.

Welcome... any chance on getting some codes? Could be something simple like the crank sensor..

 

If the fuel pump control module fails your vehicle won't start. The module controls the transfer fuel pump that is located in your gas tank. I don't know if this would set a code if it fails, but is a likely solution.

 

when you get in the car turn the key on but dont crank it, listen for the fuel pump towards the back of the car. if you dont hear it try pulling the lil orange cord locating in the truck behind the right truck lining, there shouuld be a round circle next to the trunk opening lift it and the orange pull ring should be there. its a safety feature that cuts off the fuel pump if you get in a crash to keep it from spreading gas. it may have triped some how. pulling the pull ring reconnects the fuel pump.. hope this helps..

 

Hello everyone,

We were able to find some codes and it pointed to an ignition module. Upon further inspection, one of the ignition packs was fried as well as the connector on the wiring harness. Now comes the tricky part. I've found instructions to fix the connector on the wiring harness, but Audi isn't willing to sell the parts. They're not busy right now so it's either a $1300 wiring harness or $500 in labor for them to fix the car. I'm wondering if anyone has alternate part sources that they would recommend.

We're specifically looking for the little metal connectors in step 5 of this thread:

In general, we need to work on the entire housing, but the metal connectors are especially hard to find. Does anyone have any recommendations on a good spot to find these parts?

FYI: Here are pictures of the fried connector:

Hey everyone,

So..after pulling some strings with a friend at a large dealership, I was able to get the part numbers I needed which allowed me to order the proper connectors for the ignition coil connector.

The final step was a blown fuse in the ECU. Fortunately, the entire repair was around $200 in parts. They think the ignition coil fried after being exposed so to some water. Moral of the story...never let a friend clean your engine if they help in detailing your car. Water and ignition coils do not mix. The weird part was that it took almost a for the connector to the ignition coil to fry. Oh well...lesson learned!

P.S. I apologize for rekindling an old thread...but I wanted to document the full problem in case anyone else had a similar issue.

 

"cleaning" the engine bay is the worst idea ever. i've never done it and never will.
