335D now has DPF problems!
Discussion
Two days ago the familiar beep to tell me (i assumed) low fuel happened but to my horror it was this time a message saying DBF blocked but able to drive the car. There seemed to be 3 possibilities, the above and also reduced power and unable to drive. Well the message disappeared on the M1 but re-appeared once back in town. Looking up the price of a new one produced a £2,400 shock and so i have tried to regenerate the thing. Running through town yesterday in a 40 mph limit mainly, i selected 3rd gear and left it there for 20 minutes. I didn't notice anything going on other than unnaturally high revs. After 20 minutes i did a few flat out 20 to ?0 (ahem) mph runs and the light went out. This morning when cleaning the car i noticed the tailpipes absolutely covered with black soot. Can i assume that a regeneration has taken place and that the light might stay out for a while? Has anyone else forced a regeneration in their BMW derv? Cheers.
Hi,
I had a DPF issue on a 330D. I bought a Wi-fi OBD2 adapter and Carly for BMW. Total cost was about £50. My root cause was engine thermostat which I had replaced at an indie garGe.
DPF regent is built into Carly. I had it running real time and saw the engine temp go to about 98 degrees, even on the motorway. But...it worked. Soot reduced to pretty much zero with ash at about 12g. The car now manages itself - I drive to my office once a week, about a 220 mile round trip.
If you’re in Northamptonshire or Warwickshire, can let you use it?

Do you think it’s got anything to do with the remap you had with Simon at EMaps? 350bhp increases fuelling etc
No the 535d i had was remapped at just 2,000 miles by DMS for example with no issues, although i sold it just before it reached 53,000 miles in fairness. None of my other re-mapped diesels have had DPF issues. It's simply a mixture of the car being 12 years old, 60,000 of the 77,000 miles may well have been very low rev work, seeing as the car is so high geared and lazy when pootling and could even be the thermostat i have recently been told. I will see how it goes now but i've never seen the tailpipes so black as they were yesterday so a regeneration i would say took place and cleared a shed load of soot and ash. Unless it was a psychological thing the car seemed to go a lot better this morning when i was out and about early.As I’ve said on here several times before, using high revs will not enable a DPF regen, quite the opposite in fact, as regen will be shut off if the engine revs are too high.
Regen requires several key factors and components to be working prior to it taking place, amongst them is a certain quantity of fuel in the tank, all glow plugs (and their control relay) to be working, the engine temperature to be within specified parameters, all the various pressure differential and temperature sensors to be functioning correctly, the DPF and cat to be above a certain temperature AND the car to be driven at a steady state for approx 20 minutes at defined rpm. Only then can DPF regen take place.
If your tailpipes are black, I’d suggest you most likely cut the regen short by stopping the car ...
With the right diagnostics kit you should be able to establish when the last regen took place, as it’s logged in the car’s ECU.

That is very interesting ,what is the defined RPM though ,,,I do a lot of motorway in my 330d but I rarely go over 2000 RPM as that is 90 mph,,,,,,I had read/heard that to regen you need higher revs than that so every few weeks I will on the motorway go up and down the rev counter using the Paddles for a few miles am I wasting my time then?Regen requires several key factors and components to be working prior to it taking place, amongst them is a certain quantity of fuel in the tank, all glow plugs (and their control relay) to be working, the engine temperature to be within specified parameters, all the various pressure differential and temperature sensors to be functioning correctly, the DPF and cat to be above a certain temperature AND the car to be driven at a steady state for approx 20 minutes at defined rpm.

What a strange answer. He didn’t say Simon hadn’t remapped it, he said he didn’t believe remaps caused such issues Screen shot of it

Thanks for the input. Well the light has not re-appeared thankfully. It occurred with the tank about an eighth full and after a month of on and off turbo issues. Simon at E Maps said that he has found DPF problems with cars which have been having turbo trouble and to me that makes sense too as the car won't be working hard at very reduced revs. The low fuel may have been a factor. The car is going wonderfully well now but i notice the tailpipes are a little more sooty than usual so whether i stopped the regeneration mid-stream i have no idea.

Would it be beyond possibility for diesels to have a message that says REGENERATION TAKING PLACE so that we know? If it can tell me a seat belt isn't on and that my DPF is partially or fully blocked, that my offside rear light has gone out, etc etc surely it can tell me this important information?
@grindle, I was thinking the same thing the other day about a light coming on the dash to indicate a regen taking place, I work in Distribution for a supermarket & I know the tractor units have a light that comes on to indicate a regen is taking place, so I don’t see why the same thing can’t be used on cars. The dpf on a tractor unit is massive & the heat from them is unbelievable.

My point is very clear you have remapped this car by. Simon at E Maps per the statement in your garage profile. The question is has that added to the issue/shortened the life by it over fueling etc? You don’t know nor would anyone else unles it was stripped down on a test bed to see but it might be more than a coincidence.
Classic Welshbeef. At no point has he said it wasn't mapped.Welshbeef said:

Could it be the case that remapping has increased the likelihood of DPF failure due to what remapping does increase boost and increase fuelling
Possibly, who knows. What was all the gibberish with taking screenshots of his profile to prove something that noone was disputing?yajeed said:

Good detailed post, just a slight alteration that might be useful to some is that you can have a glow plug error and still regen. Mine does anyway... it wouldn’t when it was the controller at fault tho.Regen requires several key factors and components to be working prior to it taking place, amongst them is a certain quantity of fuel in the tank, all glow plugs (and their control relay) to be working, the engine temperature to be within specified parameters, all the various pressure differential and temperature sensors to be functioning correctly, the DPF and cat to be above a certain temperature AND the car to be driven at a steady state for approx 20 minutes at defined rpm.
