TDI wagon, Its back from the dead

I started driving the TDI in May after my ankle recovered. I only made it a couple weeks before my Injection Pump crapped out on the freeway on the way home in a very bad place to be stranded on the shoulder.

I started gathering parts for repairs. I was lucky and found an Injection Pump from a newer 2002 TDI ALH engine at the U pull junkyard. There is a swap procedure on the TDI forum for swapping to the "newer" ALH injection pump.

I also did the timing belt, tensioner, fuel filter, thermo tee, fuel lines, and even replaced the third injector with the needle sensor, since I was getting codes for that as well.

All is better and it is up and running great. Now no codes, no flashing light

Drove it to work today for the first time since May and I hit 60.0 mpg on trip in. My scan gauge may need recalibrating since it was calibrated to the old messed up IP, but it runs a hell of a lot better. No surging or shudder and it finally cuts off fuel flow to 0.01 gph whenever coasting.

Now that I may be driving this again regularly, I am going to repaint it.
