Yes if the car has a "deleted" DPF then it's going to smoke.  That's the whole reason for the DPF (diesel particulate filter): to eliminate smoke, soot and ash from the exhaust.  MPG will go up with the DPF removed because most cars don't run heavy enough loads to keep the catalyst in the DPF filter hot enough to burn the collected soot and ash off, so the engines go in to a regeneration cycle.  Regeneration raises the RPM of the engine high enough to keep exhaust temps hot and air flowing for the regen cycle.  The second part of the regen cycle is diesel fuel is pumped into the exhaust pipe through a fuel injector located in the DPF, and then a glow plug ignites the fuel.  The goal is to raise the exhaust temperature high enough to cause a chimney fire, which will burn all the ash and soot from the DPF filter.  The goal temperature is at least 600 C/1100 F, so the recommendation is to never allow a regeneration cycle while off road, in a garage, or somewhere else near anything that could ignite at 1100 F.  Dumping fuel straight into an exhaust pipe and then lighting it on fire makes the the overall fuel efficiency go down.  

Regeneration happens more frequently if the engine is allowed to idle, such as just idling for heat or AC or going through city traffic.  It happens less frequently under heavier loads, such as high speed driving or going through the mountains since the natural temperature of the exhaust and engine combustion itself is going to be higher and therefore produce less soot (and will also help burn off existing soot) under these conditions.  

Performance would go up with the DPF removed if the DPF was removed after it clogged up for whatever reason.  It is possible to clean a DPF off the vehicle by using an air wand at 150 PSI assuming nothing too terrible got into the DPF.  Turbo failures which typically dump large quantities of oil into a DPF can render it unsalvageable but even these can occasionally be saved by first baking them in an industrial kiln to boil the oil off (This has to be done carefully because oil vapors can damage kiln components).  

The other technology I mentioned, SCR, is Selective Catalytic Reduction.  This works by injecting what they politely call DEF or AdBlue into the tailpipe, after the DPF.  DEF or AdBlue is simply urea in liquid form in a specific concentration (32.5% urea to 67.5% water).  Urea is exactly what you think it is, but is produced in a laboratory rather than in a liver for this purpose.  I'm not sure why, it seems dairy farms would be able to produce quite large quantities of urea without any laboratory help.  The urea combines with the NOx molecules and then splits into nitrogen, water and carbon dioxide.  I'm not sure why the Volvo was pumping oxygen out too, I may have misunderstood what he was saying.  

Sorry I'm late on this. Thats a brilliant write up. Thank you so much.

Hi Richard

Mercedes, and possibly other diesels use AdBlue as well. I know about the Mercedes because my daughter had one which needed a top-up.

I'm fairly sure it's on her latest car as well, a diesel Range Rover Evoque.

Learning, learning, all the time !!

John

Hi John,

Yes I (now) know a bit more. Many manufacturers adopted it early. It is now mandatory. BMW adopted it with all 2018 diesel models onwards.

I'm not sure of European requirements for emissions, but if your car has a functioning DPF and SCR system and no mechanical failures the tips on your exhaust pipes should be incredibly clean no matter what you dump into the fuel tank.  I worked for a company with 300 diesel powered (80,000 pound GVWR) trucks, the only time the exhaust tips got dirty after SCR and DPF was introduced was if a turbo failed and overloaded the DPF.  We never put anything in the tanks other than #1 or #2 ULSD diesel fuel, depending on the weather.  We even had a Volvo rep come check the VN370 tractors with a machine to test emissions - the results were the exhaust was not only cleaner than the air going into the air intake, it contained enough oxygen that you could breathe it.  

 

Increased Cetane levels and cleaner injectors -  always good though

Interesting. I belong to a BMW meet and greet club here in the UK. I made a big point about this when we last met. Each and every diesel car had soot (in varying degrees) in their tail pipe.

PS Just noticed what you say re: DPF. Most I know have had them removed (£1,000 fine in UK). They are, for some reason, the one's that smoke. I believe mpg is better BUT performance is unaffected despite dealer claims.

No, sorry guys. Select what you are going to do in IDrive - just hover above the selection, don't click on it. Now go to one of the buttons I have highlighted. Hold the number you wish to assign as a shortcut. You will get an OK (or something like that).

So say you assign number 1 as your home setting on satnav, simply press button 1 as shortcut. I'm not sure how this works in earlier versions. My model is 2016. I'v set all the numbers up to different things. It is helpful.

Hope this helps. If not, I will try and take some pics.

Thanks Dave. Yes, agree will need to be very careful. I have come across Rim Protectors. They are fixed in place with glue and, of course, are an issue when tyres are replaced.

I did check this out with BMW themselves. I'm assured wheels and tyre sizes are correct. So why does the rim stick out so far making it so easy to kerb?

OK have approved the post. Pop over and say hello when you get a chance:

Lovely car BTW

Interesting post here. Yes, I get that are selling something:

https://blog.amsoil.com/what-is-cetane-and-why-does-it-matter

I have used the following since I bought the car almost 2 years ago. Absoluetly no smoke and my tail pipes are completely clean. No black soot or anything. They are just silver coloured the way they were made. It cleans and also increases Cetane levels. Don't OD since too much Ceatne is not good!

On my last MOT the guy (who I know) said that my emissions were very low for a diesel. Happy Days.

Is this a problem you are suffering? What is meant by Sept.21, 2010?

I picked this up from a friend recently. Certain settings in IDrive, which you use a lot, (for me) like home on SatNav, Tyre Pressure monitoring and existing destinations in SatNav + Sports settings can all be saved as shortcuts. Just hold the appropiate button down until you get the OK.

Hi Martin,

These are worth a look. Have used them a few times. Some nice stuff they have:

Been watching this thread....So are new Euro 5? 6? petrol engines subject to the similar diesel DPF issues? Sounds the same to me, in which case, short runs in a petrol driven car will suffer the same effects as a diesel? My word, those that rule, are really trying to bugger up car lovers enjoyment.

I'm 60 next year and looking to buy my final car. It will almost certainly be an older one not subject to this current restrictive crap we suffer.

Welcome Kev. My wife has a fistfull of dollars and is waiting to change her car. I wouldn't let her buy online without a road test and check over. Seems you  have been lucky and car is all good.

Happy BMW motoring....

Lovely. Introduce yourself first, please.

As Dave said, you need to have that option in the first place before they will fold. It's an optional extra from new. BTW, they are door mirrors. Wing mirrors went out with the ark 🙂

I didn't realise BMW used ADBlue. Thought it was a VW thing, I the found this:

Some reading but a lot of help there, nonetheless.

Stephen,

I hear what you say but, to be honest, its not a particuarly "special" car. Glasses Guide has it, in first class condition, and at 100k - at around £4,995 retail. There's one here, and lots more on AutoTrader:

No, I don't think Series 3 would fit. There's quite a few on the River:

I feel for you, I really do. Apologies for my abscence of late BTW (long story).

I keep all our keys in, as Dave says, Farady boxes/bags.

Is there a Cd Changer hidden behind panels? Sorry, just searching for ideas. Were any fuses removed? That may mean they intend to come back for more.

Hope you manage to resolve ASAP. Hide those keys away BTW.

Morning Richard

As I understand BMW introduced "Smart Charging" in around 2005/6 (could be earlier in some markets) this seems to coincide with Stop/Start systems and the introduction of AGM batteries.

The smart charging system is only supposed to charge the battery when it needs it. As I understand if the battery is either wrong type or not registered everything works but the battery will become over charged which can cause system damage and or kill the new battery pretty quick.

On my brother inlaws E61 I used INPA/ISTA just tell the car it has a new battery size/type and click OK, we followed a good old Youtube how to. I am not aware of there being another way (onboard system), that doesn't mean there isn't though as I haven't checked. BMW say it is to help reduce emissions and extend component life!! The old cynic in me says they want to keep hold of your wallet for longer, thankfully my X5 predates most of this stuff.

Dave

Thanks Dave. Much appreciated.

I didn't know they replaced Vanos Seals on Wheeler Dealers ..... what model BMW was it they were working on?

Only recently saw the program. Ant was mechanic. Pretty sure is was an M3 (E46??)

Morning William

You will need Diagnostic  programs like BMW 1.4.0 or INPA/ISTA don't know about Carley for BMW and iCarsoft as I haven't used them.

Registration is straight forward 

Dave 

So Dave, do you physically fit battery first then register? Is there a way to register without using an app?

There's a few out there:

Vauxhall Cresta and the Hillman Imp. Those were the days 🤣 - the ones where it was a 50/50 gamble whether your car would start 🤪 Having said that they were the height of sophistication compared to my Grandfather's Morris 8.

My dad had a 1600E MK2 Cortina. Always kept it so clean. He died when I was 14 and at the time we lived in Wales. My mum wanted to come back to her family so we moved. We left that car in the garage. I pleaded with mum to try and sell it but she just said it wasn't worth much!.....Funny thing is I can still remember the reg no. KBL 820D

I use BimmerCode a lot and that won't do it either. Is there a really simple way?
