Hello buddy.

Only being new to the BM scene and diesel scene to, I've searched this subject on a number of forums. From what I understand the best practice is to find a company that removes the DPF internals rather than add a pipe as the MOT stations have been told to visually inspect the DPF to make surfeit has one. Obviously adding the new pipe will fail the MOT.

Your find numerous mixed reviews on this subject, where many will argue that it's there for a reason! I'm not a mechanic and or a engineer to discuss the aspects of why its there and the complete purpose but I do understand why it's there and what it does. Perhaps do the same as I did first and just research a few other forums.

Apparently it doesn't make any difference to the remap!? My 330d is remapped and still has the DPF and goes like stink. So something to consider.

Sorry if I'm informing you of info you already know.

thanks for the reply I have searched a few places and everyone seems to give quiet positive reviews about the DPF removal. not bothered about if for mot tbh just I know how common they can be to fail and I am wanting to get the car remapped and thought I might as well do it before remap. the car is only on 50,000 miles but its not in regular use so just a bit worried about it getting blocked up and fitting doesn't cost anything for fitting cause I am a mechanic, but just wanting to get other peoples on views on company's to use. who did you get your's mapped by seen a few people get there's done by angel tuning.

I bought the car done and used a trust worth friend of mine, who specialises in high performance cars. He's based in Coventry. I just told him the car I earned, age and colour. Once he got one I let him do his thing to it, one of which was the re map.

I just made sure it wasn't generic and wasn't pushing the car to the limits. It's now tastefully quick without loosing the prestige it deserves.

Just found this and thought it would answer some of your questions.

Not sure if I'm allowed to do this and apologies if I'm not, copied it from another forum where the chaps selling the pipe. Thought the other info on the benefits would aid.

BMW M57N2 x35d DPF removal downpipe

Requires software upgrade, this is the downpipe only.

The Diesel Particulate Filter on the below BMW models is renowned for blocking and requiring replacement at a cost in the region of £1400. When faulty the DPF causes substantial loss of power and impacts fuel economy dramatically. This is a fix and forget solution!!!

Coverage 3 Series 5 Series 6 Series X3 X5 X6

E90, E91, E92 E60, E61 E63, E64 E83 E70 E71

335d (M57N2) 535d (M57N2) 635d (M57N2) X3 3.0sd (M57N2) x5 3.0sd (M57N2) X6 35dX (M57N2)

March 2006 to Current November 2005 to Current May 2006 to Current March 2006 to Current January 2007 to Current January 2007 to Current

Direct replacement on part numbers - 18307807474, 18307796215

Anyone throughout the UK and Europe can now purchase our DPF removal pipe for this vehicle and release the true potential of this incredible engine.

Performance and economy software available up to 360bhp!!! Please enquire for details...

Very Important

Fitting this downpipe without the correct software upgrade will result in premature turbo failure. In order to disable the function of the DPF and align the turbo pressure to the new downpipe our software upgrade is essential. This service is available throughout the UK at a cost of £399 or alternatively the complete DIY package is available here.

What's in the package?

3" Bore downpipe with machined stainless steel turbo fitting, uprated stainless flexi section, milled fittings for lambda and temperature sensors.

This downpipe is a direct bolt-on replacement for the Diesel Particulate Filter and downpipe that are fitted to the car from the factory.

Built for performance, economy and longevity!

Performance - You will enjoy reduced turbo lag and a noticeable performance difference throughout the entire rev range, the original downpipe exits the turbo with an immediate restriction. The DPF is designed to collect the particulate matter (soot) in the exhaust and then at extreme temperatures, burn the deposits off into ash. This poses a restriction in the exhaust system and by design induces excessive temperatures which have a direct effect on your turbocharger and intake temperatures. Removal of this filter will result in an excellent improvement in fuel economy and when coupled with the performance software, the new behaviour of the vehicle is remarkable. Turbo life will be extended and turbo lag will be substantially reduced.

Economy - You will experience a 5-10 mpg improvement over the original DPF depending on your driving style and software selection.

Longevity - Your upgraded downpipe is over-engineered in 316 Marine Grade Stainless Steel and the flexible coupling in 304 Grade Stainless Steel, flanges are laser cut for a perfect fit and finish, your new downpipe should outlast the life of your vehicle. You should also expect extended turbo life as a result of reduced turbo temperatures.

How does it fit? - This downpipe was carefully developed using the Genuine BMW factory item as a template and tested on the vehicle, improvements were made to flow where possible. Every downpipe is hand made using a jig ensuring a perfect fit every time.

Noise - There is no noticeable difference to the sound of the exhaust on mild to medium throttle levels. At full throttle the whistle of the turbo is more audible.

MOT - Removal of the DPF on the listed BMW models has no effect on the MOT smoke test. Your engine will produce a more complete combustion and has been tested to pass the MOT smoke test without any issues. Petrol cars differ as they are subject to a full emissions test.

Quality - Our exhaust components are built with over 20 years experience in all kinds of fabrication and welding you can be assured that the quality of your new performance downpipe will be second to none!

      Folding mirrors

      Morning Damion I would say yes to the software update (but a Dealer will charge £££) this should be in iDrive try My Vehicle, Vehicle Settings, Doors/Key, then scroll down to mirrors and check Fold Mirrors when Locked If that doesn't work you need help from someone with a BMW capable diagnostic package (ISTA/INPA) to check if it is in a hidden menu. Be aware BMW are making it harder and harder to tinker with the cars mainly after 2019 year so you should be OK Dave

      Centre console iPhone charger

      Morning Rob His was in the car when he brought it and is OEM (car is BMW 330e 2019) apparently works well with his iPhone but not with our daughters Android phone. You could talk to your Dealer but make sure your wallet is in a protected spot 😁 as I have know idea of cost ££££. If BMW are fitting them then there will be Retro fit kits out there from the Far east so worth looking at the Auction sites but I have no knowledge of quality other than the screen in the X5 failed and I replaced it with a complete Android unit from Ebay at less than a 1/3rd of the BMW quote. Truly plug and play allows switching between the OEM CiC and Android gives better GPS and many other programs and has been totally reliable for the last 3 years (that's killed it ) Me I don't spend long enough in the car for my phone to need charging these days 😅 While the X5 has Android Auto and Carplay I have to say like a lot of gadgets they are rarely used. Bluetooth is the only thing I see as an essential Good Luck with the search for a solution Dave

      Folding mirrors

      My X6M has folding mirrors, operated from the normal button, situated on the drivers door arm rest. They don’t fold in when I set the alarm, having read the manual, there’s a setting in the idrive to activate this function but when I scroll down the menu, this option isn’t there. Can the software be updated to add this feature, surely if the button is there and the mirrors are folding ones there must be a solution, or am I missing something completely Thanks in advance
