Mine was changed just before Christmas for the princely sum of £14.61. Took about 30 minutes to fit. Only ever seemed to fault when the temperature was really cold (never when it was warm).
3 months on, and having driven through December temperatures of -17°C, it's not come back on once. I also know 2 other GTI owners have exactly the same problem, also cured with a new expansion tank.

Hey matey, I spoke to VW Gilders in Sheffield the other day
asking for a sensor in the expansion tank and was told nothing
listed on the system :scared: and that a new expansion tank
had no sensors that came with it :scared:
Where did you get yours from and what is the part number please
matey, the warning light and check coolant message comes
on all the time now and is doing my head in :confused:
any help would be appreciated,
Cheers,
Damo

I think what you need is a new expansion tank
1K0 121 407 A
as all i can see from the etka system is a plug connector to go into the expansion tank..
I am guessing though and am not 100% sure. £9.10 plus vat but prices will have changed so probable around the £15 mark inc vat
Hope this helps :happy2:

Did you get it sorted Damo ?

Not yet, been to and spoke to 4 different VW garages
and know one can shed any light on it or doesn't know lol
think I need the connector off the loom that plugs into
the coolant bottle, I asked if I needed the wires but again
the staff are not very helpfull :surprised:
Norbreck21a:
Damo,
Really can't understand what the problem is they are having ?
Here's the bottle with the connector shown
Here's the connector on the bottle
The corresponding connector from the car
and finally, the "sensor" inside the bottle (the 2 prongs) which comes compelte with the bottle on the part number I gave you
Dealers eh, why do they make it so hard ?
