Hi All Another evening on the car. Did the output tests, and it does actuate the throttle body. But what was strange was when I 'ended the test', it kept going. Had to turn engine off. We tested the pins on the throttle body plug. Pin 1: 2.8v, Pin 2, 5v, Pin 3, 10.3v, pin 4 0v (red/green wire). Pin 5 and 6 both 0v We couldn't find the crank sensor, but tests never showed that has an error. We checked all the fuses again and changed a few, just to try and still same. Engine turns over, but won't start (we are charging battery between). The throttle body butterfly doesn't appear to move when we attempt to start it, despite pressing the throttle. Anyone any other ideas? Please?

Thanks, we did check all the fuses. Did yours blow one of the bigger ones?

We took everyone out and tested them, but I’m wondering if we should give it another go. Engine will rotate but doesn’t start.

Is this with the vcds? I’ll have to find it. I did a test that when I pressed the pedal , it showed increased/decreased sensor setting but the throttle body didn’t move.

This is my son's abused and well used Fabia. It's been an amazing little car, until he went over a cattle grid, then soon after it died, and has refused to start ever since. Being towed home on the end of a rigid towing pole was an experience for me. Charged battery: Plugged in our old OBD reader, Originally gave P1545 error, plus one for air con (but it's had this fault for ever). Splashed out on VCDS system and we get. 18049 - Please check DTC Memory of A/C Controller P1641 - 35-00 - 17851 - Potentiometer for EGR (G212) P1443 - 35-10 - Signal too Low - Intermittent 17952 - Angle Sensor 1 for Throttle Actuator (G187) P1544 - 35-10 - Signal too Large - Intermittent 17564 - Manifold Pressure Sensor (G71) P1156 - 35-10 - Open/Short to Ground - Intermittent 17580 - Angle Sensor 2 for Throttle Actuator (G188) Signal too Low P1172 - 35-10 - - Intermittent We've cleaned the throttle body and did the reset sequence (with the VCDS). Sensors are showing as follows. This is when car is on, but obviously wont start. We've noticed as well, when you press the accelerator that the butterfly on the throttle body doesn't open. But when car ignition on or do a rest it does move and chatters into place. Hubby thinks the 'going over a cattle grid' is a big clue, but so far can't find any loose or broken connections. We're considering buying a new throttle body, but conflicting opinions across the various forums we've read at some length; seem to suggest they hardly ever fail even though the huge quantity available across the internet and the usual parts suppliers suggests there is a large market for new ones. Asking for any suggestions for what else we can check? Also can anyone suggest how we can test or prove if the throttle body is ok or dead. Found one youtube vid showing test values across various terminals, but it was for a ford one, so no idea if the same terminals would read the same on a vag one. Any help gratefully received.
