Drove the car this morning and all was fine, although we went through alot of water (not deep). Got in the car tonigt to pick the kids up and the EML came on and i could tell after only about 20mtrs that all was not fine.
Could this be the amount of water i went through in the morning or a tad more serious....

 

what model any mods etc

 

Its an 04 sti uk ppp, several mods, currently running about 343/350, car has never missed a beat. car was mapped by B rawle..

 

Can you read the code like on a Classic?

Given the link with water I would suspect some damp on a connector?

 

as pete has said its likely to be a damp connector. start by resetting the ecu, if the eml lights up again read the code.

Had this with mine earlier this week, except she actually stopped and refused to start not just put the warning light on!

Sent her off the the garage who took it apart and put it back together and she fired up and is running fine for now so looks like water in one of the connectors.

Despite the fact that the EML was on, the car refused to give the mechanic any specific problem code so bit of a a weird one.

I would suspect you have a similar issue. Go easy for a few days I reckon.

No codes chaps, it is booked in tomorrow morning so will see then, i left it running today for an hour or so just to get some heat in the bay to dry it but still the light is on......odd
