Need help - just cut out completely on me - wet ecu?

[clubby]

Hi i have a ibiza cupra and twice the car has just cut out completely on me.when i try to start it again it just keeps turning over,no engine man lights come on.when i leave it 15 0r so mins it starts up again and everything sweet???.the only thing i think might have to do with it is were the brain is water is getting in and once i had all sorts of lights flashing,but i dried it out and was ok after that.is there anyway of covering the brain so water doesnt get in seems a really bad place for it to be..any help would be great as near went into another car as power steering and all cut out...thanks bill

i guess by brain u mean ecu? if so then i just tied a plastic bag round it to keep it dry

Don't seal the ECU in a bag, they will sweat and induce condensation

My ecu had let water in, then it froze which messed it up! Had to get the ecu repaired (expensive), so I've put a plastic cover over it to divert the water from running directly onto the box and instead drips off underneath. Theres obviously a design fault, because there is no way that simply washing your windscreen should result in water dripping directly onto the ECU!

so where exactly is the ecu on a leon cupra tdi 04 ? . I've been trawling through threads here trying to find answers to my car's bizarre eletrics behaviour . Windows wind themselves down spontaneously , indicators flash , central locking can't make up it's mind . All apparently the result of passenger and rear footwell getting a right old soaking this winter . Mate in the local garage thinks the water is buggering up the ecu somewher in the floor . So where do I start digging boys ?
