Guys please help! Have an Audi A5 2015 Done 70000 miles. Few month ago engine light came on went to garage. Connected to computer guy wanted to do self regeneration but there was no reading from EGR he said previous owner could have turned it off or done delete. Not long after another fault came on with ad blue System fault . we decided to delete ad blue and remap the car. Day after the particulate filter fault came I was told to drive in high speed to help clear it out which didn’t work, after we had someone who cleaned DPF as filter was quite blocked. But he couldn’t clear the engine fault. Went back to remap people he has put in system that dpf filter was brand new even tho it wasn’t and cleared check engine light. After 2 days check engine light came back on , I went to another garage we fought problem was in software they have put causing the p2002 fault in dpf filter as it wasn’t new but cleaned . So the guy redone everything car regenerated itself and got correct numbers for dpf reading after regeneration, cleared check light. But same thing happened again 2 days after. The p2002 code still there but no reading from egr , he thinks its the egr cooler causing problem but also confused as it doesn’t read any pressure from it . So he suggested first to put back basic audi software on the car with ad blue problem and see if the p2002 comes back . When he tried basic audi sowtwwre it said Ad blue 0milage and car was not starting. So then he done remap - put their own software with ad blue delete and turned off egr valve to see again if P2002 comes back. Day later it came back again. Our engine gets also hot quite quick. Within 2-3 minutes it’s already showing 90 degrees
And Now we have two options open up car and see if EGR cooler is blocked or delete EGR ad blue and gutt of and delete DPF as we have been told by few mechanics if you delete one thing it’s best to delete all things together otherwise that can cause more problems. Please help with suggestions and solution!!!!
