Hello, I've recently got an ABD up and running in the mk3 (2f) polo. The block is an ABD, rehoned, washed out, new rings and bearings. The head is the ABD one, casting marks and sharp inner radius to valves smoothed out. GT cam, new valve oil seals and various other seals. Gt injection set up. It seems to run well but once up to temperature, when accelerating in the medium to high revs, the oil light starts to flash. If I lower the revs it might go off but it will come back on in medium revs, after a while it will just stay on and only go off if I turn the ignition off and start it back up again. None of it appears to affect the performance, just the oil light comes on and I can't figure out why So far I've: Tested the oil pressure - around 0.25 bar at idle, around 1.8 bar at 2000rpm and doesn't rise above that with higher revs. Replaced both oil pressure sensors, seperately, neither made a difference. Chopped off old pressure sensor wiring connectors, stripped wire back and fitted new ones. Checked the oil breather pipes for kinks and blockages - cleaned the seperator on the block during rebuild. None of this has solved the issue. If I ground the yellow wire (high oil pressure I believe) then the light wont come on at all. Only issue is I've tried both old and new sensors and the problem comes back. The old sensor is off my AAV engine and is 1.4 +/- 0.2 bar, the new one is 1.8 +/- 0.2 bar from ECP. It may be related or it may not but I cant get it to idle perfectly either, sometimes it will idle around the 920 area but other times more like 1000 - 1100. I've done ignition and idle to the GT timing guide on here but had to wind the idle screw down as far as it would go. Ignition timing is spot on. Another thing is the two white wires for the lambda probe pulled out their socket and both being white I'm not sure which way round they're meant to be so I've had to put them back without knowing if they're the right way round, is there a multimeter test I can do to figure that out? Any suggestions would be appreciated. Thank you. Joe.
Eslund posted a topic in Engine, Transmission and ExhaustWell, after one problem comes another.. Got my Polo 6N2 -00 up and running after 6 months of trial and error.. The Cathalytic converter was clogged. Not the first thing one checks.. :) Anyway, went over to the MOT, got a remark that the exhaust was leaking just a bit (where i changed the converter) Used the car for almost a month, before I got around to fixing the exhaust. Was planning on doing some welding, but solved it antother way. However, I removed the battery clamps anyway. After the exhaust was fixed, and the clamps was back on, it was time to start it up.. I thought.. DIdnt really wanna start, was chewing on the starter for about 20-30 seconds before it actually started,, When it did, the oil lamp was flashing, and no reaction from the tacho. Checked oil and oil preassure, and all was good, so drove it from the garage to a friend of mine.. Started it again outside his house, and all was working fine agin..?? Had a coffee, started it again, and the same crap was back again.. Been going on like that for a couple of days now. Some starts it´s ok, and some starts ends up with no tacho and flashing oil lamp, and an errorcode in the ECU.. The error code i get is the Engine Speed Sensor. It always starts sooner or later, but its pretty annoying to have it like this.. :/ From what I´ve been able to find it seems like the fuel pump relay gets signal from the speed sensor, and when there is no signal, the fuel pump doesn´t wanna run. (explains the problem with starting it) Also, some people indicate that it could be a ground fault. Question is, what ground where? I went around the engine bay, but couldn´t find any ground cable between engine and chassie. Aren´t there supposed to be one? Or is it grounded another way? Any other ideas or thoughts?
