Hi Guys

Mk3 TDCI (115)

Temperature gauge was showing erratic readings - would take ages to get to normal operating temperature then would drop down back to 60c and then just keep moving between 60 and 90c.

I have changed the thermostat and the cylinder head sensor and changed the coolant but problem hasnt gone away - No idea what else it could be short of the actual dash display being faulty ?

Any ideas?

Thanks

what about rad sensor??

this is usually down to the second stat playing up, its knows as the oil cooler stat.

Yep spot on - I replaced the Oil Cooler thermostat which cost me £23 and it now works perfectly!

glad you got it sorted
