Post by: alex160 on 25 June 2009, 18:27: i had exactly the same fault code on my golf on monday, so i ordered a bank 1 oxygen sensor off of VW, i had a good look on the exhaust manifold and the exhaust system and i only have one lamba sensor on my car, just before the cat. I fitted the new sensor today and car is now driving perfect. No more idle and running lumpy issue and my average mpg is now around the 40 mark instead of the 30 :)

Post by: dubcruiser on 25 June 2009, 19:19: You already have a thread running on this?? Why have you started another?? :rolleyes:

Just a suggestion, but why don't you ring the dealers? They will give you the correct part number from the VIN number which you can see in the bottom of the windscreen....

Post by: Phil18t on 25 June 2009, 21:14: it will always say bank 1 on a 4cylinder car, and sensor 1 is usualy the 1st sensor upstream and sensor 2 is the bk 1 downstream. hope that helps?.
Title: Re: which lambda sensor???
Post by: chol_gti on 25 June 2009, 21:22: so sensor 1 is the 1 behind the manifold???
Title: Re: which lambda sensor???
Post by: Phil18t on 25 June 2009, 21:31: yeh the 1 infront of the cat. if yours has 2 then you have 1 b4 the cat and 1 after it. upstream and downstream.

in my experience buy cheap, buy twice

if it was my car i'd get a genuine part - you know it will fit properly first time and you'll have a proper warranty on it too
