Hy everyone My CDI 220 54 plate, is reading those 2 codes P0471 (exhaust pressure sensor "A" circuit range performance) and P2A00 sensor circuit range/performance (bank 1 sensor 1) Please can anyone advice me what it means and What I need to do about it
Also when I drive it around it feels like there isn't any power from the engine
Many thanks

Just googling the codes seems to point to it being a sensor for the exhaust back pressure for the dpf filter. But I'm sure someone a lot more knowledgeable will say whether or not it's likely to be that. If it has a dpf do you give it a good run every now and then preferbly I believe high revs for a few miles to get it nice and hot and clear it out.

If it's the DPF, then you could try a bottle of Forte DPF cleaner, it's a great product
