Had Adblue issues with my 2016 Disco Sport after 5 years without issue. Adblue counter dropped from 14,000 Km to 900 km left overnight. The the countdown clock, 830 Km to engine shutdown. Main dealer said they cleaned the tank and sensors and reset the computer. Fault reappeared three weeks later. Main dealer then did a PCM(?) reset which fixed the problem for now (fingers crossed). However they did not check the DEF injector which seems to be a common source of the fault.
I was charged for the repair each time, second time round seemed like an imposition. Main dealer explained that they were only allowed to investigate the fault one step at a time and finish the repair once the fault disappeared. I feel that they should investigate the fault in full to ensure that the customer is not a repeat visitor for the same fault, paying for each visit to have the recurring fault fixed. What part of premium product, premium customer service are they missing?
