Dblock Posted April 22, 2014 Report Share Posted April 22, 2014 Have you tried vagcom too? Was your original TB DBW or cable? Quote Link to comment Share on other sites More sharing options...
sam7986 Posted April 25, 2014 Author Report Share Posted April 25, 2014 I haven't tried vagcom but I'm considering buying one,Are those codes useless?The original throttle body wasnt cable so a a straight swapI rang the guy who sold me the engine and he read the ECU part number out to me, it was all the same bar the last two letters... They were different would this be the case? The engine is 2 years newer than the car its going into Quote Link to comment Share on other sites More sharing options...
Dblock Posted April 25, 2014 Report Share Posted April 25, 2014 The codes aren't useless but vagcom can give you a better idea. Does your engine have a MAF or MAP sensor? Quote Link to comment Share on other sites More sharing options...
sam7986 Posted April 25, 2014 Author Report Share Posted April 25, 2014 Its got an map sensor as far as I'm aware, there was this little pipe PIC taken from another thread..But the end of it snapped off, I have another but didn't think it would make such an impact, would the ECU numbers being different be the issue? Or would it not fire at all?Thanks for your help Quote Link to comment Share on other sites More sharing options...
Dblock Posted April 25, 2014 Report Share Posted April 25, 2014 I don't know about this engine BUT in other cars having the MAF not in the right place or not even in the intake would make it do that. In another car I had which had a MAP sensor if it was unplugged it would go crazy and die as you say. It should still fire but I personally think that is the most likely culprit. The MAP or MAF sensors know air flow etc and without them the car doesn't know what it's doing. Hopefully someone with more knowledge can help.

Dblock Posted April 25, 2014 Report Share Posted April 25, 2014 How hard would it be for you to get a working MAP sensor in? Quote Link to comment Share on other sites More sharing options...
sam7986 Posted April 30, 2014 Author Report Share Posted April 30, 2014 thanks for the help, it turned out to be a bad crank sensor inside the gearbox, the phenom ring wasn't at TDC when the engine was... heres a pic of it timed up for those who didnt know Quote Link to comment Share on other sites More sharing options...
