Coolant Problem Multivan T5 2005 - faulty sensor?? Water pump failure??

Did a quick search of the VW T4 Forum - VW T5 Forum engine forum and found many threads on failed oil coolers.
Here is a couple that have the same symptoms as yours:
Oily in the expansion tank - VW T4 Forum - VW T5 Forum
2006 T5 130 Auto oil on top of coolant - VW T4 Forum - VW T5 Forum

It doesn't prove this is what's wrong with yours, but you may find these very interesting.

Cheers for that BrianJ. The bottom one could have been written by me! No overheating with mine either so praps not the head gasket after all!

I think it is worth trying a fix which is more simple, more likely and cheaper in case by chance it fixes it, rather than performing the equivalent of open heart surgery. If all else fails then you still have the head removal as a final resort. Good luck.
