Try two of these;

Check your medication is green, not black

Shakey,

You're welcome. If your moniker refers to your hands, I hope you're not a surgeon

If it is the temperature sensor (you can check VAG-COM fault codes), the medication you probably require is;

• 059.919.501.A [dual temperature sensor/sender, green not black]
• 032.121.142 [retaining spring, in case you damage the original one]

hi,
looking at the engine its on the right hand side,
of the block,its got a push on block,just under the wireing block there is a push in clip it just holds the sensor in place,very easy to do,about £10 on ebay,i was told to buy the green sensor instead of black i don't know why,
hope this helps

cheers
