I had a problem with the TDC sensor on my Kangoo, removed it, cleaned the little metal tip, problem went away for a few weeks. Trouble was, the tip was hardly dirty and I couldn't see why 'cleaning' it made much difference. In the process, of course, I removed and reattached the plug, and it could well have been this that made the difference.

When it went wrong again I didn't bother removing the sensor but followed the mechanic's advice, along with some contact cleaner - I haven't had a problem for about 10 months now.

I know these TDC sensors are relatively cheap, but it would be nice to know how many are replaced completely unncecessarily, and whether what is actually fixing the problem is just unplugging and plugging the contacts!
Thanks lucy, i gave my TDC a clean (like yours it didn't seem especially dirty) and gave the connecting prongs a little bend. Haven't had the problem in a month. It used to start around 50% of the time, so this is a great improvement.

I followed the instructions in the Haynes manual & the only trouble I had was getting my spanner in such a tight space (after removing the air filter). But keep at it & you'll get there.
Thanks all for the help
