I have a 2014 Q7 TDI with fault P245B00 Exhaust Gas Recirculation Cooler Bypass Control Circuit Range/Performance. I have 28500 miles and I have the Kerma tune installed. With the tune I don't think I can use the warranty. Is anyone familiar with this fault? I only found one other mention of the fault and that person replaced the cooler under the warranty. I usually do my own repairs and I am looking for any info that might be helpful.
Thanks
