Hi Gareth,
To clarify, for any individual car, are all the wheel sensors the same? It looks like there could be one for FL + RR and a different one for FR + RL wheels.
PiM is a few quid cheaper, when including AD shipping cost.
However, I am a bit confused about part numbers. I believe the official Bosch part number for the NSF sensor should be 0265007930, this is listed on the PiM website, but on the AD website, the number is 0265007728. The PiM website suggests the ..930 part replaces the ...728 part; if that is the case, perhaps the AD website is selling old stock, could perhaps the ..930 be an updated model?
Surprised anyone gets confused :).
