Nox sensor- part number last 2 letters

Post by greg1990caddy »

Hi everyone
I need to replace nox sensor on my caddy.
Part number is vw 04L907805 AT, there is only 1 on ebay with exact numbers and letters.
There are plenty of sensors with the same part number but the last 2 letters are different, could be QQ, KE.
It looks exactly the same. What do the two last letters mean? Are they all the same? Could I buy a QQ or KE part? Or should I stick with my exact part number?
Thanks

Often you will find the suffix on a part like a sensor is for things like mounting points of cable lengths. It's difficult to say IFA different part numbers will be compatible without trying both side by side.

I’ve just recently replaced my Nox sensor on my 2018 van , got it from a website called Xenons 4 u .
Thought I’d made a mistake buying from them at first because there correspondence is terrible 😂 but turned up next day , 10 mins to fit , engine management light goes out happy days !
Been on two months now and so much cheaper than VW.
