Hi, started throwing the code 2a27 over the last couple of days. Anyone know what this code means or how to fix it? I know you'll probably say "logs" but I don't have them yet. I'll try to get some soon.

That's a catalytic converter code. Catless downpipes? If not, then one of your cats may be clogged up\toast.

It's a cat code but can dig thru Bentley to see if I can find info if Pcode provided. Headache to look for it manually

True, could be an O2 also.

It is actually an O2 (#2) code from the generic fault description. Something about reading during shift.
Poorly translated German description. Pre cat? Post Cat? During shift? None of that available but could probably find with the PCode.

Tweedles, update after you scan with non generic fault code reader

I wasn't catless before, decided to just play it safe and order catless DPs. Just ended up ordering them earlier than I would've. Thanks for the advice!
