Hi issue with 4.4ltr diesel range rover 2010 model limp mode. DPF restriction-soot accumulation bank 1 and exhaust gas recirculation temp sensor A circuit low, these are the codes that come up l have changed the sensor and the exhaust ones same fault and codes coming up l disconnected the sensor from the exhaust and the car reved up normal then went back into limp mode after about two seconds any ideas thanks


if the ECU thinks the DPF is blocked then it won't allow full engine power so I'd suggest;

taking the car for a long drive where you can keep the engine rpm up over 2000 rpm for around 30 mins this will get plenty of heat into the system and get the system into re-gen mode

if that doesn't help then consider

or even removing it completely as you'll still pass MOT's fine without it, the key thing is to have the ECU re-programmed so its no longer looking for it


On cars where the DPF is removed then typically you get more power and more mpg as it restricts the exhaust even when new

Hi tried running the car only goes into limp mode the temp sensor would also make the dpf think it is full l need to sort the issue with the temp sensor not do away with the dpf

Hello Dave

the temp is low because the DPF is clogged up

hence no exhasut flow

if it won't go fast enough to get some work / heat into the exhaust then you have no option but to remove the DPF filter then to replace or clean it
