Hi, I have a dpf blocked error code which I believe is caused by a failed g450 sensor. Just wondering if anyone knows the measuring block numbers to view sensor data, ie dpf pressure, soot levels, ash content etc. I think this is an early dpf model and advanced measuring blocks is greyed out on the vcds.

BTW I think the 2.7 tdi is just a short stroke version of the 3.0 tdi.

Any help greatly appreciated.

Just to update this thread in case it helps other 2.7 owners

It turned out that the soot level had risen above the threshold (See measuring blocks 107 for thresholds) once this has been exceeded (you can view ash and soot levels in MB 104) then a forced regen is needed (01 engine coding 11 and enter 10016 as a code) View measuring blocks 100, 101, 102, 104 to see what is going on. The process lasts about 40 mins and temperatures in the exhaust reach nearly 700 deg c !! This worked for me so hope it helps fellow 2.7 owners. BTW oil ash Max level for the BPP engine is 0.46 mine was only 0.24 so is fine.
