Hi all,
I have a big problem with my car currently. It's a '99 Golf Mk4 1.9 GT TDi.
I was driving down the road at about 60mph yesterday and all of a sudden the engine started running really rough, with lack of pick up. At which point I moved into the inside lane, and got off at the next junction. Unfortunately the lights at that junction were on red, and as the engine reached idle it just died. Tried cranking to no avail. The AA were called and got me home safely. I loosed the 3 bolts on the injection pump spocket and adjusted the timing slightly...that got the car going (albeit roughly). I then hooked up the car to Vag Com and it showed the basic timing way out of spec (off the chart, showed 255). After many hours of messing around (on the basis that maybe the timing belt had jumped a tooth), I managed to get the timing back into spec (70 ish on the chart). The engine just about starts but there is loads of smoke coming out of the back and it's really rough, like it's firing on 2 cylinders. There's also a lot of vibration from in the engine bay, like it's going to rip out of it's mountings at any point. Hence it's just stuck at home now. To get the timing back in I had to move the belt 2 teeth whilst adjusting the 3 bolts on the injection sprocket. I assume it must be right now because the timing is only showing slightly advanced (in the graph). So I don't know what to do. Could the timing still be out if it shows right in Vag-Com, or could the injection pump be broken for that matter? Totally stumped.
A question that I'm not sure of the answer to: Is there only one place in the entire injection pump 360 degree thing that would show within range of the tdi timing graph on vag-com? I am wondering whether I have adjusted it totally incorrectly but got it in spec (according to the graph only) I say this because it smokes like a chimney when I turn the engine on!
Any advice or recommendations on what the problem could be would be appreciated.
Thanks,
Adam
