Right - more of a nightmare. I'm REALLY pissed off to be honest after just speaking to the mechanic. I've got rid of my glow plug problems, it was just the plugs. The only problem I've noticed, apart from the lights on my dash & the error log, is that my car is taking MUCH longer to start than usual. Apparently it seems OK to the mechanic though. It takes 10 or so seconds to start. It used to take 1 second, like my brothers Leon TDi. My car: Seat Leon Cupra TDi 1.9 150PS 2004. VAG-COM Log: -------------------- Address 01: Engine Controller: 038 906 019 KG Component: 1,9l R4 EDC 0000SG 5342 Coding: 00002 Shop #: WSC 06402 VSSZZZ1MZ4R103021 SEZ7Z0D2464989 1 Fault Found: 16706 - Engine Speed Sensor (G28): No Signal P0322 - 35-00 - - Readiness: N/A -------------------- Figured I'd start with a new sensor. Phoned a garage near me. Spoke with him a few times now. Every time I speak to him he tells me that he doesn't think it's the "Vehicle Speed Sensor" as he calls it. I agree to take my car in. He runs it through his computer (not VAG-COM, dunno what). He phones me and tells me it's the Crankshaft Positioning Sensor not the Speed Sensor... like he thought. He replaced the Crankshaft Positioning Sensor today (with an aftermarket sensor). Didn't fix the problem. Now he's given me some options: Get a genuine part because my car might not like the aftermarket part although it would be the first time he's seen it. If the genuine part fixes the problem then he'll send the aftermarket sensor back for a refund as it would have not fixed the problem. If the genuine part doesn't fix the problem then I'm stuck with a bill for 2 sensors I don't need. ECU could be failing. (Although everything else is OK...) He DIDN'T mention that he could have changed the wrong sensor or that it might be worth changing the speed sensor. Sounds a little bit to me like the he should have just changed the damn speed sensor, being as though that is what VAG-COM is saying, not the damn positioning sensor which VAG-COM hasn't complained about. Does anyone have any insight?
