Looking at your info your soot loading is 44 grams and you should have had warning from 24 grams. From how your indications came up it could be that your G450 differential pressure sensor could be faulty, need to buy a new one and adapt using VCDS before staring the engine again. I have attached a picture which shows when the different indications should be received and at what soot loading. Regen2.bmp

Hi, This is procedure for the pd engine and should be followed for a new sensor only, I have seen a comment from a tech that used sensors do not respond. You do not need to do a forced regen after replacing the sensor, you just need to adapt the sensor with the ignition on and the engine off. In VCDS you need to do the following: [select] [01 - Engine] [Coding-II - 11] Start Exhaust Pressure Sensor (G450) Adaptation 30605[Do It!] Tim

Hi Andy, I found myself also wanting to know this type of info. Some basic info is in the attached text document attached and more info can be found in the VW self study pdf at http://www.volkspage.net/technik/ssp/ssp/SSP_336.pdf. Did try to attach this pdf but the file was too big. Hope this is of help. Tim DPF_regen_info.txt

Yes you can tell the ECU that a new DPF has been fitted with VCDS. Go to 'Engine Control Module' then 'Adaptation'. From the drop down menu chose 'Carbon Mass' and follow the instructions. Hope this helps. Tim

Hi, have seen your post in the other thread. For the 1.6tdi think you may need the 059 906 051C sensor, which may explain why the sensors look different. Try http://www.ebay.co.uk/itm/GENUINE-VW-SENSOR-PART-NUMBER-059906051C-/380941072757?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item58b1db7975 they should confirm if its for your engine. Hope this helps, Tim

Still worth checking the G450 sensor. I believe from other posts that if the DPF is removed, the pressure sensor is still required to give a signal, even though the regen cycle is programmed out. I'm sure I will be corrected if I'm wrong. Tim

DPF's do have a limit on soot capacity of 60g maximum, garage should of able to check the ECU to check your soot reading. But also could be the DPF diff pressure sensor on its way out, easy to replace but needs to be adapted to the ECU (need VCDS). Tim

Hi, could just be the G450 exhaust pressure sensor which is ~£50.

Hi info was from the files attached. One file is a VCDS file for the BMN (PD engine) which lists all the field and block info and the other is DPF regen info from VAG. 170pd.txt DPF_regen_info.txt

In VCDS check field 68 block 2 (in VCDS measured values in engine) gives you the level of blockage of the filter (ash mass). For the BMN engine 60 grams is the max. Feild 75 block 3 will give you the soot loading. The soot loading will give the following sequence: Operating Status System Response 45% DPF Load Level 1 - Normal Regeneration 50% DPF Load Level 2 - Regeneration at maximum exhaust temperatures 55% DPF Load DPF lamp Regeneration from 60 km/h onwards ("See operating manual") 75% DPF Load DPF, SYS and MI lamp Torque limitation, EGR deactivation, Regeneration via VAG tester only 95% DPF Load Replace the DPF Unit Hope this helps.

Because you don't have a fault code does not mean that the DPF sensor is not faulty. Worth getting the car scanned or someone with VCDS to check the readings from it. Tim

Hi, just checked my invoice when I changed mine a couple of months back and can confirm that that is the latest version. Tim

Hi,

I only pay £170 tax for my 2008 VRS pd TDI, so same as the CR.
