ALH in to a 2000 Audi TT FWD - Completed!
Folks,
I've always liked the Audi TT and wished that they came with a diesel engine. Over the past couple years, I've been searching for an early Audi TT with a bad motor. I finally found one the week before Thanksgiving. The car is in great shape but the timing slipped a couple years ago. The previous owner had the car in their garage with the intent of fixing it at some point. They needed the space in their garage, so they decided to sell it. Here it is on the ride home:
I see in the past couple of month Toby_B did an Audi TT conversion and Bobob729 is in the process of doing one.
My donor car is a 2002 Golf ALH with an automatic. The car is totaled, but the engine is good. I have a 5 speed transmission from my 2005 Beetle that has the .658 5th gear I pulled when I installed a 6 speed from Ryan_P.
I'm just getting ready to pull the engine out of the Audi. After that I'm going compare the wiring between the Golf and the TT to see what all needs to be changed before I drop the ALH in the Audi. Here's the Audi in my "Blue Sky" garage (outside):
And a picture of it with the transmission removed:
I'll post more as things progress.
Update...Update...Update...Update....
This past weekend I finally had everything put back together.
Rather than post at the end, I'm updating my first post: The Audi TT with the ALH is running! I put the motor and transmission in a couple weeks ago and have been putting everything back together since then. I'm using the ALH downpipe and all the piping for the turbo/intake. I had to drill two holes to mount the fuel filter on the passenger side support. I filled the fuel filter with a can of diesel purge and then used my mighty vac to pull fuel up to the filter from the tank. Got in the TT and turned it over and it started after 5 seconds of cranking. Yea!!! Scanned with VCDS and everything looks good. Next up I'm doing new tie rod assemblies, ball joints, strut bushing/bearings, lower control arm bushings, brakes. What a blast to drive!!!!
A couple random thoughts:
1) Wiring was a challenge since my Audi was a very early 2000 and the wiring diagram did not match the Bentley. I emailed them but the only response I received from them was "we have everything from Audi". My response: no you don't. I traced the engine harness side to figure out what wires to move.
2) I could have used the fuel pump relay to act as relay 109 IF I would have traced the engine side wiring first (rather than use the "useless" Bentley wiring diagram)
3) Make sure you take notes and check everything.
4) Seat all electrical connectors.
This has been a lot of work but fun. I'm going to drive it for a couple months, then upgrade the injectors, exhaust, intercooler, and then get it tuned. What a neat car!
