Unsolvable problem?! 2008 Touareg 2
Hey all-
Brand new to the forum, so apologize if I am posting in the wrong area, or missing relevant information. I am desperately seeking help as I cannot find the issue. Here's the run down.
I have a 2008 Touareg 2, V8, 4.2L.
I bought it used (~95k miles) and almost immediately had an issue. #5 is misfiring. Since then, it has been in the shop 10-12 times with no resolution. Here is what I have done so far:
Through all this, #5 is still misfiring. The dealership is out of options, suggesting that the ECU is faulty and needs to be replaced ($1600) or they need to swap the #5 injector with #1 to see if that is the issue (~$1000+). Neither of these options sound reasonable because a) the ECU was already tested and b) the injector is brand new, yet the exact problem (#5 misfire) has persisted before and after the injector replacement.
What the hell do I do?!?

- Put in all new plugs/coils
- sent the ECU to SIA electronics in Chicago for testing - no errors
- replaced the injector with a new injector on #5
- swapped #1 for #5 (plugs/coils)
- checked the harness (dealership said they did this, but not sure if they did or are just tired of me)

Welcome to the forum.
You don't say where you live?
You need to get your motor scanned (preferably with VAG-COM\VCDS) for any error codes logged in the ecu and post them, that will save a lot of guessing.
