I am having to pay to replace the adblue tank as the car is 1 year too old and we serviced with a local garage.
On the warranty it states:
"The provisions of the CITROEN contractual warranties do not reduce or exclude the legal guarantee against hidden defects and the legal guarantee of conformity that benefit the consumer."
The adblue tank fault is clearly a "hidden defect" and therefore shouldn't Citroen replace for free?
