This may be stupid or a very big question, but why are there different ECUs for manual and automatic engines ?

There's 4 different ECU's that are fitted to the 75 and ZT:
NNN100692 MK1 manual NNN100720 MK1 Auto NNN500340 MK2 Manual and Auto NNN100693 Replacement made by Bosch for X-Part to replace the NNN100692 after worldwide stock of new 692's were completely depleted As you can see the MK2's use the same ecu, mainly as a cost cutting measure so they only had to stock one part They altered the tune assemblies so that the manual and auto could share the same ECU on the MK2.

Just re installed and everything back to normal.
Fired up as normal, no problem - but not counting my chickens just yet! Need to take it back the 190 miles to my dad next week as it's due for MOT on the 18th - then the week after it'll be coming all the way back to Wales again, as my fathers moving back here permanently. I'll be chuffed if it's sorted, especially as I only borrowed it (at the end of November!) as I needed an auto after breaking the 5th metartarsal in my left foot.. It never rains... If it fails again Russ I'll be in touch

I used this to clean it up:-
But I suspect any half-decent alcohol based electrical cleaner would do the same job. I've also used some rubber strip around the edge inside the metal case, using the screws to clamp it down to (hopefully) protect it in the future, should the same thing happen again. Myself, I'd only use WD40, GT85 or similar on the connectors at the top, and only once they have been connected back to the ECU.

As Ben says above electrical contact cleaner or IPA to clean the board.
Don't spray WD40 or any other maintenance or protection product on the board, this can cause all sorts of problems they can be more trouble than they're worth. Both Brian and myself have had ECU's that have failed due to various products being used on them. Check the drains regularly and do the spy hole mod to make it easier to do is normally all that is required Russ

Just done a 35 mile round trip shopping run; no problems, all good.
So fingers crossed for the run over to Bedford next Friday.... By the way, Russ what do you think about "plastic bagging" the board in the metal case? Do you know if any of the IC's run warm or hot at all? Just thinking of more waterproofing for the future, although I'm hoping the rubber strip I used might well be waterproof enough. It doesn't go across the top edge where the main interface is, but should still provide some much needed protection to a good level. Can't believe no-ones thought of it before, TBH! Even putting some silicone around the face where the two halves of the case join would be a good idea, too, I think.

There is also a atmospheric pressure sensor on the board so the case cannot be totally sealed otherwise it won't work correctly Russ
