Ok, so heres the thing
Removed plenum, no problems... Not one sign of the multiplug anywhere! whats that I see, nearly below the dispack
Off comes the fuel rail to get to it....
Yey!
Hang on a minute, this is not the plug! The connections are different to the one sent by Autovaux
So...
Under the car, give it a yank and yep, its the plug alright!
On the phone to Autovaux... wtf

Autovaux say that there are several different revisions that all go by the same part number... So basically they sent me 'a' sensor and did not tell me that there were several revisions and they really need the number of the current sensor. i understand that if someone rings up with a part number then hey will get what they want but when the part number has several revisions you would have thought they would ask... Anyway, they were supposed to ring me tonight to let me know if they would get one out today or tomorrow but alas, no call. Fingers crossed I get it 2mo or Thur, my car is sitting there with the fuel rail n plenum in the boot...

Not happy now...
