Hi my partners car (audi a3 cabriolet 2010 2ltr) keeps going in limp mode, I've had the fault codes read and they are coming back with p0112 and p2463 I've had teraclean out and it shows the dpf isn't blocked. The car won't even go into a forced regen. I've also tried replacing the MAF sensor but with no luck, can anyone help? Thanks
