Jag Landrover engine warning lamp on,
After a scan P049B, A common code on many modern diesel vehicles, In this situation fortunately we had prior knowledge of the vehicle having a replacement Diesel Particulate Filter, (a leaking/cracked dpf allows soot to pass and and contaminate the low pressure EGR system) A quick check of the exhaust tailpipe can tell you if you’re wasting your time cleaning 😉
So in pictures, we removed the low pressure EGR cooler filter and what do you know it’s clogged with soot, Cleaned everything rebuilt all good 👌🏻 This is accessible mostly from the N/S wheel arch
