111S ECU failure - what to do?

Recommended Posts

It turns out my Elise has been filling its ECU with water, it now doesn't work.

Does anyone either know anywhere that can repair (is that possible?)

The conformal coating has mostly protected it except the big chip just above the centreline on the left (below the tidemark) in the photo.

Or does anyone who knows the whereabouts of an S2 111S  ECU (A117M0109F, different from non 111S) for sale (new or used)?

@jonnyboy recently had one repaired, I think?  May be able to point you in a direction.  They are hard to get hold of used!

Many people go aftermarket with a programmable ECU such as Emerald.

Thanks for your prompt replies, and very sorry for my lack of response. I'm new to the forum and haven't yet trained my spam filter to let notifications through :(

I'll have a go with multicare...
