Got the sensors today but the wrong ones.
at first I thought I have been sent wrong ones but when I checked ebay order they are what I ordered.
I just put in part number 07Z906051A when searching for them and ordered the genuine Audi ones that came up for a good price without double checking the number so have bought 079906051A. I can replicate the results on ebay, searching for 07Z bring up both 07Z and 079. Looking at some aftermarket sensors they are listed as compatible with both 079 and 07Z and also 03G. The difference is 1 mounting hole on 079 and 2 holes on 07Z but since aftermarket parts are listed as compatible with both so electrically they should be the same. I am also not sure they are original Audi, they do have part number on but came without any packaging and were a bit cheap for OEM.
Not sure what to do now, if they were easily accessible under bonnet I would give them a try but considering the work involved I don't really want to mess around. But not doing them tomorrow would mean to wait till next weekend
