You can´t know what I know and don´t know, so no need to apologize.. :) I can´t get too much information about this issue.. Yes, I know that timing is normal to advance, but I guess not this much to set this 00550 code that I am getting. If I set the base timing at idle so it is perfect, and...

Update: Today I have set my timing so it is/was spot on, on the blue line in the middle. But, it seems to be a lot more jumpy than what it have been before. If I restart the engine, sometimes it jumps up to almost too advanced, and wait a couple of minutes, it´s too retarded. But in measuring...

Thanks for all the answers! It´s really helpful! I didn´t trust the TDC mark on the flywheel because it wasn´t lining up with the injection pump. So, I took out the glowplug from cylinder 1, and found TDC that way. The 0 is not visible anymore in the indicator hole, but I thought that the...

I have since my last post checked if I have had any valve/piston contact. And I don´t believe so, I can´t see any cracks on the lifters, and I have removed all glow plugs and rotated the engine a couple of revolutions. I have also checked my old markings, and they seem to be on the same place...

TDC

Thanks! I will try to set the timing this week. How do you mean more or less centered? If I look through the pulley I can only see a bolt and a nut, not a hole that is oval... Or do you mean on the other side, on the pump side? But no, I have never loosened those bolts, when I replaced the...

Yes, that was of course my first thought! And, indeed it was fuel gelling in the filter. But since then I have drained my tank completely dry, cleaned the pump sender unit, replace the fuel filter. The problem is not resolved. After that, I did try to run it from a fuel can, just a hose, from a...

TDC

Hello! I own a VW Passat 1.9TDI Syncro from 1999, which has a AFN engine. I have been chasing down a 00550 code which is "00550 - Start of Injection Regulation: Control Difference". It has been running quite okay, but when the temps has been lower it has been running quite rough, and sounding...

0 and line, which one to trust?

TDC?
