Does the sensor go into the main block under the distributor and coolant bleed valve housing ?

Didn't see the thread but - WD40 will sort out damp start problems, if that is indeed what has been caused by your wash-down.

Just FYI, I've only ever used WD40 to clean my engine bay, and the car starts fine afterwards as it's both a solvent and a water repellent. WD40 is recommended in the Haynes manual to get the car to start if the engine is very damp.

I've only experienced damp start issues with a worn-out dizzy cap and rotor arm at about 80-90K on the clock IIRC. However, as you've changed both of these this can't be the cause. Very likely water ingress somewhere if it started after the wash.

Spray liberally around dizzy, leads and other exposed plugs. Definitely worked for me when I was experiencing problems, but changing the dizzy hardware sorted them all out permanently.

Perfect I did use some wd40 that evening so guess that helped
Just now seems to every now and then when I come to a stop the revs die down to like 500rpm then after a few seconds back to normal but never did it before and rev counter bounces at times even when still and idling ??
Did change get fuel filter the other day too and seems to use more fuel then before but no leaks
Much appreciated

check the connections to your alternator are tight.

the dip is sometimes a drop in current, and seeing as yours has had a swim by the sounds of it. It may not be working at 100%.

Just seen this post - my 216i Cabby in Malaysia developed an annoying rough idle and a miss/hesitation at low speeds - turned out to be the plugs leads had failed - a new set of plug leads and it was perfect again.
