A6 C8 50 TDI question from a newbie 🙂

[ianw5704]

Orange engine warning light came on recently & local VW / Audi / Merc specialist ID'd as NOx sensor B (ref part No = 4q0907807e) but can only source replacement part via Audi dealer?
Does this sound correct .........or some other lower cost options available?
Expert help / advice would be much appreciated.

Shouldn't it be 4K0419091E .. you can buy these at AliExpress for 200,- as I have recently done!

Ali express, buy Chinese once and then buy genuine later.

You're right, after messing around for 2 months with Chinese sensors it didn't work after all and after buying the Audi original it was fixed in a jiffy!

We all have to learn the hard way, human nature.

Because of the price difference it was worth trying ; 200,- vs 800,- and the Chinese stuff could be returned anyway and it did not affect the cars driving performance.

If at all possible I won’t buy ANYTHING Chinese, unless unavoidable. I will pay more such as my new very expensive made in NL Phillips shaver or simply go without

You will be surprised how much comes from Asia that you are not aware of..

I don’t have a problem with Asia per se, my issue is with the Chinese Communist Party and specifically Ping Pong the mad. My Phillips razor said made in the Netherlands so must at least conform to EU country of origin rules.

Philips DAP (domestic appliances) are fully produced in Asia .. but I understand your point of view, XI JP isn't my best friend either!
