honestly i'd ditch the shop, unless you really like them. it cost me $850 to have a full timing belt kit installed (so i can't imagine why it'd cost way more for a pump install), and that's even in a beetle. at the point of having them send to rebuild, and then install id probably just find a used one and have it installed. What exactly makes you think it's bad? also how many miles do you have on the car?
it's at right at 200k
I just had my TB done 150 miles ago or about 2 months ago, the car has been sitting since then. For some reason, all german shops are expensive where I live. My visit to the local shop was out of convenience, they quoted me the above prices and another one quoted me $1400 to get a timing belt done. I have a shop off the TDI list(SMS European if you're near SoCal) that has been nothing short of amazing, with awesome communication and reasonable prices but they're 100 miles away from me.
Basically what makes me think it's bad is, one day and I noticed it struggled to start then I looked under and there was a puddle of diesel leaking from the IP, I started it to see where the leak was coming from and it was from the injection pump. So I ordered the two seals and VAGCOM to replace the leaking ones, I got everything in and seated and I couldn't quite get the injection quantity low enough, so I had it towed to said local shop and they may/may not have messed with the IP settings(they killed the battery in the process, hopefully not the starter) but it literally runs the same and is smoking a lot and revving really high or same as before.
Now I ordered a resealed pump from Canadacatalyst and I'm just waiting till I have time to take the car down south to have the resealed IP installed.
