Can anyone help?
I have a mk3 with a high temp. readout yet the engine is running at what seems to be normal temp. Fan kicks in but only on 1st stage setting. If you take the top of the expansion vessel the water is not boiling consistent with the temp. readout on the guage.

Has anyone had the same problem? Can you give me any advice? I would be very grateful!

Many thanks in advance!

Joe
