Ecu bleeding resin
Discussion
Hi All
My S1 is bleeding resin from the ecu.? The car has been off the road for years I purchased it cover a year ago most work is now complete, I run the engine from time too time and drive around our private cul-d-sac with no problems but have noticed I have resin running from the ecu It is not hot to the touch I can only assume the previous owner had work done on the electrics would they have sealed the unit with resin? Do I need to worry about this? I'm looking to have the old girl mot'ed in March and worried it will give me problems on the trip to the mot station.

Not very clued up on that engine but I think that is the ignition module? Expensive little buggers.
Whatever it is I don't think it should be exuding resin!
Had you left the ignition on for any time without the engine running? It may not be a problem but I know on old fashioned basic systems that will "cook" the ignition coil?

This is the second time I've noticed this, the last time and this time I ran the engine to fan temperature fan came on as normal took her for run in the street ten minutes put her back in the garage checked for any water leaks underneath and spotted the resin semi soft again hanging down,
So no ign. Left on.
Everything is working ok ?

I wonder whether that is some kind of thermal goop designed to conduct heat from the electronics to the case. If so, you can expect heat related problems probably leading to a total failure. This would be a good time to start sourcing a replacement. In the meantime, if you have any way to reorient it so the leak is at the top, that might delay the problem for a while.
I will remove the top screws and see if the unit comes apart, if so look for any obvious burning
And if possible run the engine and see what's going on in there.
If been reluctant to open it up as everything is working ok.
I know some electrics have been carried out on the car by a previous owner as all electrical alterations have been marked up on the wiring diagrams that came with the car, cold start relay removed and fitted with non bias switch and fan temp override switch, that's why I'm thinking the electrician could have opened and sealed the unit with resin? as the book says the unit can have issues with water Ingres.
Many thanks

Update
Removed the module today it still had about 10mm of resin covering the pc board and no obvious burning.
What I did find was the earth lead from the outside of the unit had parted company with the earth point at the chassis, not sure if that would make any difference?.
Cleaned up the set resin on the Inner wing run the engine for half a hour with no further
Leaking and no heat coming from the module.
As suggested I'm looking for a replacement module just in case.

I've found a not too expensive replacement part on the following website:I've replaced my ignition control module almost 2 years ago and it is still working.
