Adblue alarm and mileage countdown  VF73ABHZTHJ705766 - 2017 Grand Picassa Adblue alarm. Citroen dealer Southampton identified fault p2a00 nox sensor failed and replaced injector and sensor. The total cost was £1100 and having researched similar problems with other C4 owners, I hoped to obtain a refund as there is an extened warranty in place. However, informed by Citroen that warranty only covers adblue tank and so no refund was available. The car has a low mileage of 12, 825 miles but due to age of the car warranty not applicable. Sad that a known issue is not viewed more favourably. Not impressed and out of pocket. By ChrisLitton  On Thu May 15 2025, 09:57am
