unfortunately Skoda UK takes a dimm view of techs helping this forums users so you'll find it hard to get a definitive answer from someone that really can help you... i wont rant on about Skoda UK's obvious dropping of the dogs danglies though.

Note: the above is my own view and not that of Briskoda.net as a community forum.

As you found, there are plenty of posts about this DTC across the range of VAG cars. The most common cause would appear to be a faulty temperature sensor. The original troublesome black one was modified - the new one is green. I assume your friend fitted the latter as a replacement? If he has access to VAG-COM, he could log coolant temperature with the engine running and see if the readings show any problems. Sorry, but I can't advise which Measuring Block that is.

... yeah ...he fitted the green one .....

well... i'll just have to "look around" forums :P

have a Happy Christmas !
