Red face Re: The tdc sensor .... or coils?

Seek out Probe Distributors - they are Essex way
but also have an outfit in Preston (under a different name)
The coils to an improved design in 2009, did carry a three warrantry. Also with the TDCs, are much lower cost than most suppliers. They do a next day service.
Personally I have no business connection- only bought from them. These ignition specialists supply numerous units for many marcs.

Finally on to my favorite hobby horse.
If you only replace one coil , the others usually fail later like a domino affect. Replacing all with Renault parts is eye watering. But this action makes sense, if a good replacement can be obtained.
In the past like on road side recovery call outs, most cars have a quick repair done. The occupants delighted to be on their way.
' Out with the faulty coil - In with the new one.'
Five/ten minutes at most (once the truck arrives & diagnosed which coil - one of four but usually No.2!)
However it is also best practice to remove the spark plug from the particular cylinder & clean it.
Should the breakdown be on a dark, wet wintry night/day
-THEN do this secondary clean/gap check ASAP. This driver following professional advice will clean them all.
Reason being when a coil fails it causes extra load on the other cylinders and messing up of the plug attached to the faulty unit. Naturally there are other problems with cars other than coils !
