DPF Regeneration 530d GT
Discussion
Hello everyone,
I am new to the forum and recently acquired a 2014 530d GT.
As most of my driving is mainly done in and around town, I would like to know what to look out for in terms of DPF regens. I used to be very familiar with my E350 Mercedes, but this is new ground for me. Are there any signs of the car doing a regen like for example holding onto the gears for longer, engine/exhaust note changing etc?
I would just like to know what to look out for as to not run it into the ground.
Many thanks in advance.

Get it to full temperature and take it for a run down the motorway. If in doubt get the diagnostic done to check the DPF back pressure and that will tell you the state of the DPF and also with the right software when the last regeneration was done. They can force a regen if needed but a motorway run is a good place for it to happen. My old 330d had its original DPF at 160k without any problems but it got a regular motorway run
This is according to the indy i use.
For example in Milton Keynes you have the A5D dual carriageway with no stops that runs the length of MK - about 10 miles.
Drive up and down each way in top gear at 60ish using cruise control.
I do this whenever my car - BMW E61 530D manual - starts feeling a bit sluggish i.e the DPF starting to bung up. Works so far and performance is back afterwards.

Don’t know about the E61 but 60mph in top in my F10 530d would have been about 1250rpm. I can’t see running at that for 20 minutes having much effect. For example in Milton Keynes you have the A5D dual carriageway with no stops that runs the length of MK - about 10 miles.

Agree, rather 3rd or 4th for 10 minutes at motorway speeds, certainly not top gear
Not sure that is a good idea to my knowledge at least. I have been told doing that will have the opposite effect. The high air flow will cool down the DPF as opposed to help heat it up.The car I am sure is programmed to manage all aspects of the regen in order for that to take place. I am only missing the clue as to when it is happening. I have had the car for 600-700 miles now and no problem at all. That said I am sure it has done a regen at some point, just not to my knowledge haha.
All well and good, I will equip myself with Carly to observe the situation. Would have done it this week, but a family member has had to go into the hospital, so that takes priority.

Once you know the signs it is actually fairly obvious in my experience with my 640D these are the obvious ones:I am new to the forum and recently acquired a 2014 530d GT.

Holding gears longer is definitely obvious more so when booting it
Engine note is subtly different a bit rougher (more noticeably when cruising as the gearbox wants to still keep the revs down during that period)
Exhausts get very very hot once it is really in full flow (I mean like barely touchable)
If you stop or turn off the car the front flaps behind the kidney grills may open to allow the extra heat out (I have had this only twice in 2 years though)
MPG drops off
Carly has some good areas including Soot Mass, Ash Mass, Last Regen mileage, Average mileage between regens and does have one option for the Hex code which changes during regeneration activity.
Having had a chat with a BMW Tech, motorway speeds for about 20 minutes keeps everything happy
. Which is why I have taken the long way to work two days this week (including the weather).Not a BMW but had a workmate who ran a Range Rover Evoque diesel.
He used to travel @ 15 miles to work everyday on the motorway at @ 60mph (and back home again on the motorway), and came into work the one morning complaining that it had suddenly started driving funny, saying it felt sluggish on acceleration, the MPG was down (he used to make a daily note of his MPG - some sort of challenge to himself to try and achieve the factory results), and said that when he parked up at work, the car felt and smelt seriously hot (to the degree that he was concerned it might catch fire).
I told him it was just the DPF regenerating by getting mega hot to burn off the particles and nothing to worry about.
He wasn't totally convinced so contacted the dealership he used for servicing, only to be told the exact same thing I'd told him.
I said it should tell him about the DPF regeneration in his owners manual, only to be told: "I've never read it!"
Most sites state that to carry out a "passive regeneration", the vehicle should be driven at a sustained speed (usually over 40mph) on an A road or motorway, for at least 30~50 miles. The cooling effect of the airflow will be nowhere near enough to cool the DPF during a regeneration (As I have posted,after a 15 mile motorway run at @ 60mph, the DPF on my workmates Evoque would still be burning hot).

Pretty much all of them state you should run the vehicle on an A road or motorway on a regular basis, at speeds over 40mph (and none of them seem to suggest you need to run in a lower gear, but I have heard a BMW dealers service advisor suggest it to a customer).
