My VW Transporter is in limp mode. Glow lamp blinking and engine lamp orange. I runned vcds Van throwing p24b3 and p2463. The soot content is 72% and it won't accept forced regen. What means heater control for particulate sensor? Is that the control unit in picsScreenshot_20260126_180114_Gallery.webpScreenshot_20260126_180245_Gallery.webp? Or is the heater somewhere else?

Please post the following

1) Full VCDS Auto-Scan​
2) Engine blockmap - Ignition ON/engine OFF
3) Engine blockmap - Engine running at idle​

Morning, I could only read blockfiles with marking CAN. I dont know if this is correct? Attached filesThank you

Possibly your VCDS cable is an older one (9+ years) as they can't read data of controllers using UDS protocol - as T6 engine?
Only HEX-V2 and HEX-NET have the UDS capability.

Obviously - because ECU thinks the DPF is overloaded with soot - as it seems DPF regeneration haven't happen for a while. Normal distance between DPF regens happen every 200-300 km. The limit for soot mass is 45 g.

Thaank you very much for your time. aprichieted. Probably change dpf then?
 
There are a number of criteria that must be met to do the regen - engine temp, fuel level (above 1/4), no Fault codes present, soot level not too high (above 40g maybe).

If you can trick the van to think everything is met then it might work

This is the list on my van for a standard regen, so probably doesn't need all of them for a forced regen. I'm sure MMI will add more information.

Fuel level above 1/4 is not true. My van can start e regen with the fuel in the red zone.

While I have never tried to see if a regen happens below 1/4 tank of fuel, I have seen it documented in quite a few places. Nice to know that soemone has tested it though thanks @Skyliner33

I suppose a forced regen might require a bit of trial and error, and would be good to have it documented.

Documented 🤨 ?
On T6 criteria to allow regen to start is fuel low light not on. I would expect running regen isn't stopped by fuel light but still haven't managed to time a regen to stretch over from no fuel light to fuel light on.

However, a few members have reported that the regen starts even with fuel low warning light ON.

Yeah my T6 has always been happy to do a regen whatever the fuel level.

Post in thread 'DPF warning lamp with poor fuel economy'

Regen is not about speed but revs.
2000 - 2500 rpm is fine. It will regen at idle but takes longer.
Start stop is auto disabled during regen
Less than 1/4 it’s inhibited on older software. Newer software reduces this, but not sure what new limit is. Mine doesn’t seem to care about fuel level now, just gets on with it.

If it’s doing something different then something is not right.

If you never let it finish then it will always feel like it is trying to regen.

Mine does not start a regen when fuel low light is on (below)

Part 4 - Other observed changes with the ECU update​


Relaxed soot accumulation limits for DPF regeneration​

Before update DPF regeneration was initiated at soot level (calculated) of 24.0 grams. The DPF regeneration was finished when soot level (calculated) was reduced down to 6.0 grams. By taking advantage of still hot exhaust gases the soot level could go even as low as approx. 5 grams - because of so called passive regeneration.​
​
For the updated ECU software the limits are respectively 30 grams and 9 grams - thus approx. 17% more "space" for soot (21...​

Either replacement or could try cleaning. Anyways, the reason for not regenerating needs to be resolved.

Would resetting value in measuring block 068 to 30% and then try a forced regen help?
Click to expand...
I don't think yours even have those measuring blocks? It would be under engine adaptations.
 
I can confirm that trick reset the value 72 to zero and then do forced regen for me worked. Of course after finding l had to open security acces S12345. The blinking of glow plug lamp and engine orange lamp disappeared Car runned like hell again for 3 km then the engine lamp comes on again. Not the Glow lamp thanks God. Scanned the car again and found the same fault for part ash sensor. Probably only a new one to 250 euro will cure it. Opinions?
