[Fletcher]

What are the service intervals then?? as 12k sounds a lot.

 

[TomBear]

TDC Sensor mate. Had these problems with mine.

Under the bonnet underneath the throttle body there is a sensor on a banana shaped holder with 2 bolts either side. It should have a blue top as this is a common problem on them and the new part is blue. Old part is black. If its black, get it changed asap as its faulty and a common problem. You need the sensor and the wiring loom, about £25-30 from renault.

If its blue then take it off and give it a clean up with carb cleaner, see if that helps.

the TDC sensor sits on the top of the bell housing to calculate the position of the crankshaft, it reads engine speed and allows the ecu to change injector openings with changes in engine rpm.

Basically tells the ecu when to fire, as its got to be when the crankshaft is at a certain position and obviously if its not feeding this information back, the ecu doesn't know when to fire so it doesn't.

Hope this helps mate, it is a common problem on the Mk2 Ph1 1.2 8vs

cheers this seems like a problem with mine! im gonna do this next sat! ... do i actually need to take it off fully, and if so, do i need to re position it so it sensors correctly, or does it just sit in one position ?
