After laughing at the stealers for Ł82 per sensor i bought from German ebay. All was fine got the sensors today and they work lovely.
But my other (original 2) now don't seem to sense at all.
I have put the new ones at each end of the bumper, so original in the middle 2 holes - does this make any ods???
Also just realised the sensors are different numbers;
original = 4b0 919 275f, new ones = 7h0 919 275f
Apparently these are the same part, can anyone confirm??
Any light shed is very welcome...
