hello all, I recently retired from the Army and bought a used 2015 Q7 for my wife to have a nice daily driver. We got about 20k enjoyable miles out of it and then it went into limp mode on me driving back home from Columbus. Couldn't get above 2k RPM, but ran normal besides that. Check engine light cam on and the curly spring symbol that I relate to glowplugs. Had it scanned at a buddy's shop and it said EGR. Went to Audi dealership and bought a new one, installed. Got about 50 miles out of it, then it all happened again; check engine, limp, EGR codes. Took it to Audi and dropped it off. They had a look and said I must have gotten a bad EGR from them, they replaced, free of charge. I'm happy. Drive it home and the same thing happens again! Drop it back off at Audi and they look and look. They had my Q7 for a total of 2 months! They finally call and say it's the EGR cooler and it would be $4000 for them to replace. I laughed at them and then picked it up and waited another month to get it into a Euro luxury car specialist shop to replace the ERG cooler for $600 and I bought the EGR cooler from an Audi dealer online for $600. I get it back today and the Sonofab$^&% does the same thing on the way home!! I don't really know what to do now. Has anyone had these problems? Could it be whatever tells the ECU that the EGR/cooler is bad? ECU? I'm lost here and hoping someone has had the same problem and won.
standing by! thanks, Matt
