Thanks, will post up my findings here. I'm leaning towards the ignitor or a bad ECU, outside chance coil packs/MAF.

I haven't had my friend over with the oscilliscope to do the testing.
However, I did this - started car, let idle. Car cut out between 20-30minutes. Felt the ignitor, it was hot/warm. - let car cool down, prob 30 mins. Started car, cut out immediately. Felt ignitor, it was cold. This is making me consider it isn't the ignitor. 2nd thing I did was pull the TOMS ECU. I found brown liquid stuff on one connector of the 5 connectors of the TOMS ECU. I thought this would be the problem. So I clean up the connector, and put in a STOCK ECU inside this time. Car still cut out. Damn. I took apart the TOMS ecu, didn't see any components leaking. Odd. Spoke to my mechanic, said check sparks, HT leads, ignitor, coils. He then said I'd have to check the fuel pump after this... I will hopefully check by next week, although if we presume something is heating up and failing, then it tend would rule out the ignitor as this was stone cold and the car still failed to start. The car then started fine the following morning. It could still be the ignitor of course but it's an outside chance. And I think I can rule out the ECU also. |

On the US-spec Mkiv TT, the intake air temp sensor is part of the MAF, and is tested by checking the voltage between THA and E2 of the ECM connector...as well as the resistance between pins 3 and 4 on the MAF. All of this is in your TSRM.

Thanks I'll check that too. Haven't done anything with the car, I need to allocate a day for testing and get my friend over.
