I bought a 2020 CPO to replace my 2019 that got crushed by a tree. Silly me, I didn’t have the dealer check to see that the PRG controller had been updated. The battery died while I was installing a hitch. I tested the current and sure enough it doesn’t time out. The original TSB says the update part is 63350XC10B. I’m shopping on eBay rather than spending 2 hrs driving, twice, even if they would cover it. I see there are versions up to 10D. Does it matter which one I get?
