hi
we cleaned the main ecu with hot water and soap:rolleyes: we dry it very well(20min hair drier)after that using a thoot brush and aceton we eleminate some kind of stain...it fire up right after!even the sound o the engine was realy great(i use to have clak clak)!! so to be sure check your ecu unit from water and stain! the sympthome was: immo failre+abs asr vdc failre
thanks

Appreciate old thread but might help in future…

I had the exact same warning errors that you have described. My immobiliser actually came on as i was pulling out of my drive so the car was stuck in the road. Tried all the usual bits and bobs and in the end got a tow to the garage.

Turns out a loose connections in my fuse box meant I was only getting 2v of power, hence all the problems. A tighten up of the bolt and now we're all good. The connections looked tight but only when checked with a spanner was found loose! Worth a check if anybody has this problem.
