I have a warning which has come up several times although Jaguar recalled the vehicle for a ad blue upgrade

it keeps telling me that the ad blue is contaminated when I cannot see how

Gas anyone else had this issue by the way Jaguar tell me that to resolve this I need to replace the tank which costs around £800

Maybe worth running some fresh AdBlue through the system.

There are fake batches being sold and also if they are stored in direct sunshine it can degrade the fluid (Petrol Station forecourts as an example)
