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

last year my Q5 went into limp mode while on the highway, glow plug dash light came on and was flashing. The result was a bad EGR cooler and the dealer replaced under warranty. I had 66k miles at the time. Took the dealer 5 days to fix and they gave me a loaner car.

Can’t confirm that I had the same code as I didn’t have my OBDeleven at the time to check it.

I’d try flashing your car back to stock, drive for a bit and hope the dealer doesn’t flag you TD1.
