Did anyone try cleaning theirs AQS ? I gave mine a wash down with IPA , not had any issues since.

Can you give us a run through of how you cleaned this?

Sprayed the entire sensor in IPA. Not had the issue since.

Did you leave it insitu or remove for cleaning? Might try some contact cleaner myself.

I just found this on AliExpress:

€21.75 | Car Air Quality Sensor 5QJ907643 For VW PASSAT B8 Golf 8 MK8 Tiguan For Audi Q4 Q5 For Skoda Seat Kodiaq 5Q0907643D 5QJ 907 643

Works like a charm, OEM part for chinese market

Hey guys, i have the same problem with my superb. I can only find 5q0907643F from Vemo and Aic. They should be compatible right? On autodoc it says that they are not compatible with superb 3v5.

So right now i dont have a clue which sensor to buy. I wanted to order 5q0907643F from VEMO but it says its not compatible.
