Big Problem..........

[jamesmc]

The oil has gone between the copper and plastic sheathing
so 2 things, either leave it and a little oil may get onto the MAF that will wash off, or you replace the harness.

I would leave it and maybe wash the MAF just once,,I have not heard any complaints by leaving it

I respect your knowledge, but am somewhat sceptical that the oil would migrate all the way from the gearbox connector to the MAF
By MAF I assume you mean Mass Air Flow Sensor as fitted near the front of the engine bay.

All you do is:

NOTE: Gearbox MUST be LESS than 50c or conductor plate may get damagedHand hot....

Remove metal cover (1 10E torx)
Unclip cable
Turn yellowish ring ounter clockwise until it hits stops.
This "winds" out the electrical wiring connector.
Remove connector.
Oil may run out so have a small bucket/tray under. About 1/2 L (1 pint)
Leave loom hanging to drain any migrated oil.
Undo 7mm bolt in middle of spacer.
Pull spacer out. Again watch out for oil.
Now wipe out any excess oil with rag.
Spray connector, loom and up harness sheath with electrical cleaner, brake clean etc etc.
Wipe a smear of oil on new o rings.
Wiggle spacer in (only fits one way)(keep yellow ring tag at 7 o clock unwound)
Do up 7mm bolt hand tight only.
If you have one replace O ring on electrical plug. If you dont have one front one off old spacer may fit if required from memory???
Wipe oil on this o ring area.
Push plug into spacer. It will not go right in yet.
Now whilst holding pressure on plug, wind yellowish ring back to stop from 7 to 11 o clock.
This winds connector back into spacer.

replace metal cover. Replace lost oil (coffee filter and funnel )
