This is a bit of a story, but I am running out of ideas and would love some input. I have a Octavia mkII vRS Tai (2012) I was driving home on the motorway and suddenly at the bottom of a hill, on the way up, I noticed that my car didn't respond to the throttle. The glowlight flashed and as I limped to the nearest exit, the engine died. I had a ****ty code reader that gave me P0321 (crankshaft) and P0326 (turbo sensor) right after the incident. I turned the car off, tried starting it and it just cranked. Then after 5 minutes it started but stuttered whilst idling. We towed it to our local mechanic and it's been there since. We changed the crankshaft sensor first, as the symptoms pointed to that. We also checked the wires from the sensor to the ECU but that didn't solve the problem either. The car cranked for 5-10 seconds before starting at this point. Later I found a thread about someone changing the MAP-sensor and he had identical issues but that didn't help either. We've also changed the camshaft sensor and the belt. I went to my mechanic today and he said it just cranks, and it doesn't want to start at all. And now it seems that it throws out different engine codes during different occasions. He has a theory about the diesel particle filter being clogged up or outright withered to ****. I have no idea what to do, so any suggestions or guidance is greatly appreciated. Thanks!
