EDC / P0471 / P2BAD (300CDI / W461)
EDC light came on again.
Scanned. 4 instances of P2BAD ("Fault code not found in database) and P0471 ("Exhaust Pressure Sensor A Circuit Range / Performance").
DPF differential pressure sensor recently replaced, about three weeks ago.
Any insight?
Thanks.
Have you tried cleaning the EGR valve?
We assume this has lasted the 6 years from when you had the problem!!
Thanks for updating.
I recommend and advocate the use of fuel carbon cleaning additive every fourth tank full to keep DPF and connected issues at bay. Our Garage uses either Forte or in my opinion better still is BG Products additives:

Other brands include Liquid Moli, Wynn's, STP,
HYDRA DPB-100- Diesel Power Blast - Fuel Injector Cleaner with Diesel Additives and more these are just some examples. There are more intense cleaner about but requires Garages to perform the cleaning.

Cost equivalent to GBP45 approx.
You mean $450 USD. 400GBP !! But it's done.
I get it now. Its Hong Kong dollars, at approx 10:1
