I bought a 1997 Passat TDI wagon for $600. Test drove it & no issues but on the way home it went into limp mode. When I started the next day, issue was gone then came back on. I believe it has happened 3 times & all at freeway speeds. No check engine lights. The motor has 267k on it. Power on it when not acting up I am more than impressed with. I took my Edge 2 controller and plugged it into the TDI but it does not seem to read the boost and was no VW to select, just had to clic VidMate k "other". Not sure if there is an upda Mobdro te that can do more, I will look. The car had some motor work a little over 30k ago: Crankshaft, rod bearing set, crackshaft gear, front & rear seal, main bearing set, lower timing cover, clutch disc, release bearing, oil pan gasket, boot, connecting rod bolt, seal/flange, timing cover. There was some screws, bolts & lube too. The other thing is 5th gear is out. Where do I start on troubleshooting? I will buy a code reader if it helps. If so what would be a good one with out breaking the bank?
