Right then, everything has been ok since goin through the puddle. However, I may have a different
problem.
On Saturday 13th, I went through that puddle, and a few minutes later the engine management light came on. Later during the night, it went off on its own. Anyway, I ran VAG COM the next day, and it read a mis-fire on cylinders 1, 2 & 3.
Took Ian's advise (and that of others) and ran it for a bit.
Anyway, this Saturday (20th), I got up and the engine management light was on. Got leigh at JBS to run it, and it said something about "an open circuit, cylinder 2" or something like that. Cleared the fault, and that was that. However, it's decided to come back on this evening after finishing work!
Not sure if it's the same
problem as saturday 20th, or something else. My vag com is being poo.
