Does anybody now if these unis can be opened and cleaned ie the oil that wicks its way up the wiring loom and into the ecu. AA

You do not have to open it up,buy a few tins of lighter fuel and give it a good wash, then put it somewhere warm to dry out.

it will be OK after that, the oil does not harm the components

Are you serious? I don't know how much one of these ecu's cost but I don't fancy filling it with lighter fuel! surely there must be a safer way than that?regards AA

You fill it full of lighter fuel,shake it around and empty, do it one more time, then place it some where warm to dry out.

I have been using that stuff for 40 years, it will dissolve and clean off any oil contamination.

Short of a ultrasonic cleaning tank with a similar fluid there is nothing else.

If you open the unit then you can use lighter fuel and a paint brush. then spray the board with clear lacquer.

I would never joke on a serious post

yea i took mine apart and cleaned it with electrical switch cleaner, I would certainly go with tv's method and also use a bit of compressed air to ensure terminals are completely dry/clean

I also cleaned back my wiring loom and dried it out and then used a copious amount of seam sealer on the wires just before they enter the ecu to act as a barrier in case the same thing happens again..basically created a blocade type blob..u could try using silicone..ie instant gasket, and now keep a check on the loom every week or so..

How did you open up the ecu and get inside? also as far as I am led to believe the oil comes up between the copper core of the wires and the insulation so putting sealer on the outside would'nt help. I was told by one of the merc mechanics that once you fit the modified pilot bush this totally stops the oil getting into the wiring. what I want to do is get inside the ecu and clean it with board cleaner but don't want to break anything opening it.
Its the procedure of getting inside the ecu I'm after. regards AA

You do not need to open it you can just fill it and shake it.

Most of these plastic boxes can be opened

The outer casing is held to the inner..the strip with the terminals on it, by four clips moulded onto the outer box.. two clips each side near the end of the outer casing.. Right get a flat blade, ordinary kitchen butter..knife.. and be careful push it gently into the gap.. at the centre..any of the two longest sides...between the outer casing and the inner...the slight gap should be just visible.. slide the blade of the knife gently along the gap towards one end until it stops then twist the knife to prise apart the cases and u will see the clips near each end.. when u have dislocated one.. slide something .. sloped wooden or plastic part of a clothes peg? into the opened gap to keep the clip from relocating.. then slide knife back along casing to other end and repeat procedure.. then same other side and things will fall apart.. as for the sealer I bared two of the wires .. well apart.. my sealer is really an experiment..tho i do know if the problem doesnt return again i will give up checking in a few weeks.. the plan of action then is to leave the keys near an open window . ha if only

Tho personally I would still prefer tvs' method, common sense and less intrusive so less to go wrong,

TV is right, lighter fluid is harmless to most electronics, it evaporates and leaves nothing.

Buy a tin of lighter fluid, pour some into a dish, you'll see how quickly it evaporates, after a bit nothing will be left.

Its also great for cleaning bicycle chains, although my preferred cleaner for that is fresh diesel

Rightly or wrongly I opened mine this morning following extractor fans instructions. A little fiddly and I would add to XTF's instructions that there are 2 little tabs in the centre, one each side which locate up inside the lid. you have to be careful when putting the box back together ie. press the centre together with 2 fingers while pushing the 2 parts together. anyway when I got in there there was no sign of oil whatsoever, all was bone dry so I left well alone and retreated to safety. regards AA

By the way thank's for all the advice, regards AA
