That is usually a sign that the head gasket has gone.  When oil and water mix you get a.....that colour sludge.

hmmm, would indicate that the head gasket is going - of course it could just be condensation.

Is the car using more water then usual??

you can expect a little gunk in this cold weather especially if your driving short journeys due to condensation but that seems loads....

Yeah well did think head gasket but I have heard that it can be normal to get some gunk from short journeys

I have it as well but not to that level. I'd go with condensation but there does seem a lot...

I'd clean if off and use the car a bit more see if it still occurs

I bought my car last year and then the mayonnaise started. I too thought **** but it didn't/doesn't use any water. This disappeared when the weather warmed up. I do a 64 mile round trip commute so it gets nice and warm and I check my oil weekly and this week there is a sign of mayonnaise appearing again although not as bad as yours. Clean it all out and monitor it but like already mentioned it's ok unless your loosing water.

It will be condensation as the car is not heating up to full temperature. Keep an eye on the coolant level etc just incase it is the beginning of hgf. If i were in you're position i'd do an oil service on the car and monitor the results.

my cousin brought a mk4 gti 3 years ago, when we was viewing it i see the same amount of gunk as you got there... i straight away said walk away, it was a good price and it was exactly what my cousin wanted so he chanced it after speaking to his mate and said alot of the gti's do suffer with condesation/gunk build up, it was at 192k and its now at 230k and still going strong, if i was you... clean it up and see how you go... hopefully it be nothing to worry about :happy2:

There is your likely problem. The best and most enjoyable way to reduce the white goo is to perform an Italian tune up once a week :)

Nothing to worry about, usually caused by short journeys, or driving like an old woman
