In June my dad bought a new Fabia with the 1.2 12V petrol engine. He's done about 2,000 miles in it from new.

Couple of weeks ago, he was driving during a very heavy downpour (lots of standing water on the road, spray etc) for a few miles. He completed the journey, but after leaving the car for an hour or so, it took a long time to fire up when he returned to the car. It eventually started, and he drove home. He reported it drove fine without snatching / hesitation.

Next morning it refused to start: the starter motor turned it over happily but it didn't even cough or splutter. He called Skoda Assist, and the attending technician diagnosed water had penetrated the ECU casing (the ECU's bolted to the bulkhead).

The technician tested various loom connections to the coils packs and injectors, and eventually got it to fire up. I should add that there were no warning lights, and no faults logged in the ECU.

It's been fine since that incident a couple of weeks back, until yesterday morning when it again completely refused to start. Skoda Assist technician came out, tested various loom connections and managed to get it running, but he wasn't happy so eventually trailered it to the local Skoda dealer for more diagnostics. He believes the "ECU might need reprogramming" which seems unusual for a 2014 car.

Anyone know if this is a common problem on the 1.2 12V motor? Or any ideas what it could be?

Thanks, Craig
