Management light to Ad blue

[Dave q5]

Hi 

I have had trouble with ad blue on my Q5 2015 a year ago the garage changed the filter and now the fault has come back and the garage says it is the sensor this time at a cost of £500 +labour and vat can anyone advise

Hi realistically I know Audi have a sense of humour with these thing but that sounds way out of town, I would definitely get a second opinion and a code, at least you can find out exactly which sensor it is and as they have a propensity for using the same sensors on a lot of VAG cars you will probably find the one sensor cheaper for for another model, I would hazard a wild guess its the Nox sensor.

Hi try deleting the codes but keep a note of them and publish on here so we stand a better chance of diagnosing the fault, that price though is wrooooong.
