Hi guys need some expert advice been struggling with this for weeks and dont know where to go next.
Story starts that a bought a 2005 a5 2.0 tdo blb (140) with what I was told needed a turbo.
Got it home to find that she needed more than a turbo, the head was away and she was pressuring the water enough to cause a fountain out the open water bottle. I could also hear the chain on the balance shafts that I read so much about.
Decided that the engine would cost too much to repair and bought a passat BKP (140) to swap the engine into. picked up the passat and drove it 280 miles home. Good engine driving well.
So both cars still starting I remove both engines and build the Passat engine into a A4 engine (brackets sump oil pickup rocker cover auxiliaries and there mounts) and while I was at the replaced the hex drive for the oil pump. new clutch etc
Used the A4 injectors and injector loom as they are different.
Fitted engine and she wouldnt start and checked VCDS. No faults that should stop her starting but live data not showing engine speed and the rev counter doesnt move when cranking.
Found out the crank pick up wheel also does crank position and needs fitted with a special tool to ensure its at TDC so borrowed 1 of these and fitted a new crank seal and changed from passat crank sensor which had been working with the a4 crank sensor just in case the passat 1 was different.
Rebuilt engine and refitted it but still the same thing. she turns over no problems but doesnt even sound like shes trying to start (no fuel) still no crank signal checked the plug on the crank sensor and it has a GND 5v and a 1.4v with and without the sensor connected is this right?
Probing the signal wire while cranking I couldnt get a signal out. Bought a new sensor and tested it on the bench and cant get a signal out of it either I tested it by moving the old pickup ring in front of the sensor with 5v applied and connected to a oscilloscope.
On VCDS if I look at measuring block i think it was 52 it a shows crank and cam speed and a sync value. the cam speed goes straight up and the crank remains at 0 then after a few seconds of cranking it goes to up but then the cam goes to 0 and the sync value goes up. I cant remember exact values right now but I can get them.
On a happier note I opened the headlights and removed the orange lens and fitted projectors that I think look very good. I'll post photos when I get them refitted.
