hi all,
long time no see, anyway just thought I would add to the multitude of posts regarding this fault, and checking howto videos on youtube which I have been scrutinizing up down and sideways.
After a couple of months of intermittent M and S flashing, (off and on to clear) then on the first start of the day, after about 5 min driving start flashing (off and on to clear) then it finally crapped out to limp home and just wouldn't clear even using icarsoft I had to do something.
I followed all the cheap checks I could do, basically checking for continuity on all the leads by unplugging from the headers, xyzswitch and solenoid socket, these were good, didn't bother with the xyz switch apart from a slight rearrangement of the drain and plug to attempt to clear any water ingress.
Found a slight oil trace on the engine ecu, cleaned it out with wd40 and ordered a new injector loom as a matter of course, but have not fitted it yet due to postal strikes.
but none of these resulted in clearing the fault.
Lots and lots of rain here over the last few days, so after it dried up, entered from the passenger side and found the carpet edge sopping, followed all the wet under the passengers seat, and found the transmission ecu had a load of gunge under one corner, after a struggle I managed pursuade it to break loose (as the bracket nuts were rusted solid, took it out for inspection and found it had corroded one corner so out came the trusty wd40, squirted plenty into the ecu and let it soak, dismantled the plug and checked that (it was clean) checked continuity of the harness that was ok, and went in to order a second hand one off of ebay, again just in case, went out and fitted the drained dried ecu, and tested it but again to no avail.
Finally the first thing to arrive after the strike was the ecu, so fitted that that evening and went in and hugged and kissed er indoors as it all worked after clearing codes.
Needless to say, my way of approaching the problem more than likely had people throwing hands in the air, but this small stuff is not my area, I deal in machinery that needs 3 ton chain blocks, 5-1 reducers for torquing down, as well as sledge hammers and 10 foot poles for reluctant nuts.
After all this the only main gripe I had was that all the official fault code lists and solutions I have read, not one did I find that had a solution for solenoid valve 1 2 or 3 monitoring (s/c to ground or o/c) but then again I strongly doubt they would have had this particular solution anyway.
Quite a long post just to give another thing to check, yes I could have bought a replacement ecu and just randomly tested it to see if it worked but I like to see a fault before doing anything.
hope it helps someone
