RETURN TO SENDER

Hi

 

The ole 1.8 16v's runing fine temp wise, absolutely rock solid where it should be, but today the dash temp gauge light came on. Better safe than sorry, so pulled over and called yer RAC to have a shufty. The guy said his dad has a mint MkII Golf with the same problem - temp sender unit sending inaccurate message.

 

So, he changed the engine temp sender unit (and it was corroded), but the dash light still came on. The only other thing he suggested was it could be the temp gauge inside the coolant expansion tank. But this, he said, is built within the tank and he thought you'd probably have to replace the whole thing (which doesn't sound too cheap).

 

Any ideas, or similar prob solves out there?

 

Cheers, thanks

it will be a low level warning light in the tank

If by that you mean the coolant level is low, that isn't the case - checked the coolant level and it's fine.

 

Or do you mean that the the low level warning light in the tank will actually be faulty and giving a false reading?

The coolant level sender in the bottles fail and say the coolant is low even when it isn't.

Okay, thanks for that. Is it correct that the sender inside the expansion tank is actually built into the tank so you have to replace the whole unit - ie, new expansion tank - just to replace the sender?

whole tank, but you should be able to pick up a second hand one for a couple of quid.

they're not expensive from VAG new...

 

Personally, I'd avoid the ones from GSF or Euro as the plastic weld around the middle isn't as good quality and I've had several burst in the past... :(
