All sorted now ... car also sprung a big coolant leak the day after my original post, and had a lot of other work in the 'must get it seen to list' so took it to the local VW Specialist for:
- Oil Leak Fix (was a pressure switch + the gasket round the filter housing)
- New rocker box gasket (this was leaking at the back)
- New plastic coolant junction thingy on the front of the engine
- New alternator belt
- New power steering pump belt
- New engine thermostat (car didn't heat up enough - and ran too cold on motorways, bit of mayo in the filler cap)
- New brake fluid
- New dipstick (don't ask, it wasn't me that broke it)
Now car is toasty, and for the first time the Thermotronic heating system actually works!
For ?256 inc collection and delivery.
Now to try and convince better half that she should occasionally look under the bonnet ... and hope I don't get complaints from the neighbours for the oilslick outside our house :embarassed:
