Nos

The battery was disconnected for a full day when gearbox was removed to push out stuck crankshaft sensor. So ECU had enough time to reset. As for monitoring there are loads of data that can be monitored and without knowing, it would be like looking for a needle in a haystack. I have tried to do that while driving but there is nothing that pops out.

I can try to do live data but need to know what to look for. Any tips? engine is just over 100k. Tensioner, slides, sprockets were all replaced with the chain. I have looked at pipework and could not find anything, I'll get through it again and also brake servo vacuum hose.

Sparks plugs are new. I do no think that the problem is with ignition coils as the engine would not run smoothly and this is not the case. It revs up fine till the red line while stationary.

Hi All, Over 3 months ago 1.2 AWY started giving me troubles as it starter losing power and going into limp mode at 3k RPM Quick connect to VCDS initially showed lambda that was replaced but no improvement. Reading this forum found that it could be bad compression or timing chain. Compression checked and all cylinder showing ok. Timing chain was also replaced but still same problem. Couple weeks ago the engine light came on and VCDS showed speed sensor error. Cleared error but if I revved engine while stationary the error would comeback and it would not rev over 4k RPM. So had to replace the crankshaft sensor. The sensor was seized and broke off while trying to take it out. This meant the gearbox has to come out to to get it replaced. Anyway the sensor was replaced. There are now no errors in VCDS. The car revs fine while stationary upto red line but still goes into limp mode while driving at 3k. Any suggestions? I have nothing to grab on, the engine runs smoothly while idling or being revved but cannot find why it goes into limp mode while driving. Are there any tests that I could perform? Thank you

This week I noticed that my clutch pedal sometimes is getting stiff/hard to press. Only noticed this while driving not when still. It never happened two times in a row. The biting point has not changed and it does not slip. Any suggestions or ideas what to check? Do not want to get stranded in the middle of nowhere. Engine 1.6TDi CAYC 105 PS Thanks
