Starting problems - TDC or Immobiliser??

Hi, I have a Clio Grande 1.2 X reg with an intermitent starting problem. On more than one occasion the engine will turn over but not fire. This is regardless of whether the engine is hot, cold, been left overnight or been left for 5 mins. Breakdown told me it was an immobiliser problem, and Renault have told me (over the phone) it sounds like a TDC problem. I have read that a TDC is hard to diagnose on a diagnostic test, so am after some advice as to whether this sounds like an immobiliser problem or a TDC . Renault have quoted 121 for a diagnostic and refit of a TDC ?
Many thanks . . .

It sounds like a TDC issue. The TDC is located at the left of the engine above the bellhousing and is held in place by 2 x 10mm bolts. Remove it and clean the end with a rag (it's magnetic and collects small bits of metal, impeding the signal) after cleaning replace and try again. If it needs replacing it's a 30min job and costs about 20 -30 for a sensor.

Hi Melly - may be worth having the TDC sensor cleaned as some members have success just by removing the sensor and giving it a good clean - a new sensor is around 28 - if you could fit it yourself it would be cheaper than the cost of the dignosis.

Being a relatively cheap component I'd say it was worth changing it anyway. I cleaned the Meganes TDC sensor rather than replacing it - but I'm a tight git
