they went on my mk4 gti but luckily i`ve only got 2 lambda sensors, i wouldn`t of thought all 4 were gone,i only had one gone but replaced both just in case ,the car was a bit sluggish when driving it round but only used it for a few day`s. now got the engine light on again which is lean feul on bank 1 which is just a plug change i hope
