Hi All,

Looks like thermostat has failed - temp gauge fluctuates, temp sensor replaced issue still seen. Does anyone know if I need to replace the whole housing or if I can source & replace the element as there seems to be 3 screws on the outside of the housing where I guess the element is located ?

Any advise would be helpful.

Thanks

Jamie

Just the thermostat. It comes with a replacement sealing rubber ring. It's easy to replace ... use the search faciliity of the Forum. I replaced mine recently and I did it without even needing to drain-down the coolant!

Thanks David - did a search earlier and most results relate to the TDi and the posts for FSi relate to swapping out the whole housing. How much did you purchase the part for - looks to be around £70 ?

Quite sure you can change the thermostat without the housing, be cautious with the housing, they get soft with age and are easy to damage beyond repair. Did you change the correct sensor? Does the temperature in VCDS follow what's happens on the dash?

Got it wrong and deleted my original post after reading Nick's reply

Also found this rather basic workshop guide on stat replacement


Cheers Spike

I vaguely remember the workshop guide recommending to remove the gearbox mount and suspend the engine on an engine hoist to give better access to the thermostat housing, which is a bit over the top but i will admit the thermostat is a PITA to get to...

It is indeed. I don't have fond memories of doing that, particularly as it didn't need doing and turned out that it had been done the year before! Would definitely drop the engine a bit next time as that mount is quite easily undone.

The better news for you is that I still have the undamaged 2014 manufactured part. Would £30 posted suit you?
