Hi all, I have a 97 Jetta TDI with manual trans has 195000mi it was well taken care of found a lot of reciepts in the glove box and it was a 1 owner going by the carfax. : I just purchased the car and about 15 miles later the CEL came on and I've been trying to figure out what's going on. When I test drove the car I thought there was a turbo issue because I did have a 2000 automatic back a few years ago and it just seemed under powered. Further down the road going uphill it would drop to 30MPH then on the flat 70 was about tops. I got to the autozone they scanned it and came up with the P0380 and P1550. I came on here and looked into it and took out the computer and replaced the vac line in there and checked to see if the wastegate was working and all was good. Found a crack in the intake hose and was so happy thinking all would be great but it's the same. I have an old scanner not the vag-com it came up with codes of P1252 and the 380 again and pending codes of P0605 and P1144. Then a few days later I changed the fuel filter and well it's all still the same. I just ordered a timing belt kit and a harmonic balancer because it does have the bad belt squeel. I have not taken the valve cover off to check the timing of all three places (cam, pump, trans/crank) so that's what I'm doing tomorrow. Any other things I need to look for before getting really frustrated with this thing? N75?? timing off? Thanks to everyone and I'll let you all know what I do and what works.
