You can check those in the live data measurement. You just need to add the parameters you wish to view. Blow into the upstream pressure port: no change in voltage or differential pressure. When the DPF regens, the temps will go to 500+ Celsius so you can tell. Thread starter Olof; Start date Jan 4, 2025 Jan 4, 2025 #1 . Here's the latest readings, which assume to be the correct working figures; DPF Differential Pressure Sensor (at idle) = 0. I would expect the jump happens when the "Measured" reaches the DPF regen trigger point - here 21 grams. 00 /min Normed load value: 0. Shown here from 8hPa to 23hPa Delta, Diff just reads 0 - 10 - 20hPa. A likely/possible cause is too high differential pressure End-----(Elapsed Time: 01:50, VBatt start/end: 14. I have decided I'm going to measure the pressure differential when the DPF is about to regen and then right after. 6g, 0. 00 g Differential pressure measuring instrument testo 510 – Pocket-sized differential pressure measurement hPa testo 510 measures differential pressure in the range from 0 to 100 hPa. One hose connects before (upstream) the DPF, • Differential pressure probes to 2000 hPa • Absolute pressure probes to 2000 hPa • Relative pressure probes to 400 bar • Temperature probes from -200 to +1250 °C • Probes for measuring current/voltage Long-term monitoring also during dynamic measurement (only testo 521-1/-2) • Measurement data can be saved separately or as a Using Bimmer-Tool app to check DPF condition and perform exhaust backpressure in #BMW X1 (E84) with 2. It shows cause of regen was DPF differential pressure. Can someone please educate me on what values I should be reading and checking to see if the DPF is really plugged? 09-Cent. 24 meaning the DPF is restricted. I noticed that there are two different diff Soot mass calculated before regen was 11. 0 hPa --> 4. sensor: uncond. Anything else stand out or worth checking? EDIT: I addressed a continuity issue in the back pressure sensor connector so it is now baselined and matching the intake pressure. You see that the atmosphere is of relatively thin vertical extent. 00 hPa Service regeneration: Release conditions 3-FRF_STATE_RGN: 9 Did some information gathering today. 14. Scott,thanks for the reply,ok I understand now I just looked at your car profile and jumped too the wrong conclusion ,sorry. I'm "hoping" that my DPF has a capacity of 200g (a wild guess) and that the warning is just BMW's way of saying "we think it should be replaced at xxx miles". At idle it shows around 36 hPa. -- Status: OK 0000. Is this typical? The reason why I'm asking is I have a check engine on with P2002 code and trying to figure out if the DPF is plugged or it's something else. 75 g Particle filter: soot mass calculated: 18. 0 hPa/(m3/h) Curiously, the live data also indicates roughly 1000 hPa pressure differential pressure before I But I'm still puzzled as to the root cause of 00452a. 8V)----- ----- ----- Address 01: DTCs cleared ----- ----- Address 01: Engine (4G0 997 401 ) 10:27:10 IDE00021 Engine RPM 823 /min IDE00427 Particle filter: difference pressure 0 hPa IDE00428 DPF: offset for differential pressure 0 hPa ----- ----- Address 01: Engine (4G0 997 401 ) 10:28:37 Intake Pressure 998 hPA (14.

Distance since last DPF regeneration: 1100 km DPF Differential pressure @ 800 rpm: 15 hPa DPF Differential pressure @ 3000 rpm: 140 hPa Soot level: 36 g. However, if the DPF differential pressure was 6 kPa with MAF at 25 gm/sec then: 6 / 25 = 0. It has a differential pressure sensor for the low-pressure EGR, and if you changed a differential pressure sensor, then I would suppose that's the one you changed. H. I deleted the fault codes yesterday and after driving 50 miles the fault codes or the EML have not returned. . 9 psi). 00 hPa Filtered differential pressure of the particulate filter = -10. 70 PSI) Exhaust Back Pressure 2033 hPA (29. 2 mV IDE04263 Sensor for particle filter differential press: raw value 5 hPa The captured maximum differential pressure (978 hPa) across the DPF is quite high - even at full blast! Some related messaging going on here: I think this might indicate that the DPF differential pressure sensor is actually just fine. Here mine are, in case anyone would like to weigh in on where these fall relative to a "normal" range: At idle (770 rpm): exhaust back pressure 1201 hPa (17 psi); DPF differential pressure 12 hPa (0. I would guess that your DPF differential pressure sensor is probably faulty & giving out incorrect data. When the DPF light+CEL came on. For example: MAF = 25 gm/sec. However Bosch / Delphi / VW and all parts manufacturers refer to them as differential pressure sensors. I see that the raw value is around 50 at idle, and it raises when I rev up the engine. This test confirms if the diesel Exhaust back pressure before particulate filter - corrected = 1071. I have replaced the pressure sensor previously, At the DPF sensor I get a Earth signal, 5 Volt feed and a varying voltage when pressure is supplied to sensor. Swapped that out (£21 something for the sensor (not from a main dealer)) and car has been fine since. 0l TDI H23 9458 Revision: 85H23--- CVN: 500D7A2038D3FF82B866C2AD Coding: 01190012032410081000 Shop #: WSC 07455 444 00000 ASAM Dataset: A differential pressure sensor, with ports mounted in front and behind the DPF, monitored the pressure difference within the filter.
