Hi all
Bought a new black and a new blue coolant temperature sensors for my Golf today, black one fits fine and my temperature gauge now works

On removing the blue one, as i expeced its seen far better days, very rusty where the previous owner didnt have antifreeze in it! Anyhow i went to put my new blue GSF one in there and its too big! it wont sit in the whole properly

Anyhow i rang my local vw garage for them to tell me that the part in NLA. this is obviously absolute crap as i have searched on here and found people who have replaced theres with genuine. Anyhow my question is where can i get one that fits? If main dealer is the only option, whats the part number?
cheers
