I've tried a search but no luck.

Can owners please let me know if there are any "known" issues with the engine?

Any links to the "DPF" issue? what is the issue and why does it fail etc?


Is the 335D twin turbo like the 335i?....what's the engine number? i.e N54, N52 etc?...any geeky information most welcome!...

Thinking of getting one. Owners please comment on the engine.

Haven't driven a 335i, although here's Evolve's view on the differences between a 335d & 335i (both stock).

cheers for that!...

..not really looking at comparing the i v/s d

but mostly want to know about the 335D engine...from a buyers perpective.

What issues have owners had with their 335D?

I am on my third 3 litre diesel (2 530d Sport and my 355d Sport) , and my missus has a Golf 2.0 tdi (manual) having come from a lifetime of petrol (m3 and m3 csl plus many more) so here are my thoughts...

its all about the 'torques' , as Clarkson would say - and lots of them. Initially it takes a bit of getting used to - i think that the immediacy of the petrol 'urge' sometimes seems to be missing, but i think that is often the gearbox more than anything, and of course the rev limit is pretty low. There never seem much point going above about 5500 rpm.

But of course they just pull and pull from about 1200 rpm and the engine characteristics (imho) are better suited to an auto box so its basically just plant right foot and keep it there . And if you are not in the mood for frantic driving it can be lazy and economical.

I had a sport gearbox on my last 530d, with paddles, and that was programmed a bit more for the hooligan (me) , and the one in my 09 335d is quite sporty too (also with paddles) and love that too.

Dont get me wrong - the 335d will never be an M3, but then an M3 won't give close to 40mpg on the motorway and 26mpg around town. It's a compromise i guess but it really does shift when asked.

My problem is that I do actually miss having the sound of a petrol. I have never heard a diesel that doesnt sound like a taxi at some point in its life - especially on cold mornings - although its not as bad as some make out - and a sports exhaust doesnt really improve the situation much?

I cant really comment on any issues with the engines - mine have always been sort of 3 years old and less than 60k miles

Of course now i have halved my annual mileage I am thinking i will end up back with an M3 .. but thats another story

Forgot to mention - if you are lacking performance in a 335d a remap is [relatively] inexpensive and achieves monster improvements. A friend ran a 335d with nearly 700nM and that was faster than the CSL's we used to own

[Cyprio]

ah okay,

I haven't had any issues at all with my one, but then I've only had it for a few months, though it does get used every day - and this is the problem!

Every day I do a shortish journey, not long enough for the car to get up to proper operating temperature, and this apparently is one of the causes of dpf issues. There are ways of getting around this i.e removing the dpf (pretty obvious) but it's something I personally wouldn't do just in case there were any warranty issues.

Another thing - these 335d's are not that brilliant with fuel consumption (well, let's say my one isn't) I never get more than around 25-29 mpg unless on a long run, although this should be expected, they are 3 litre twin turbo's after all.

Hope this helps (a bit).

My vehicle is a US-spec 2011 335d. The engine is the M57N2. This is probably not the same engine as the Euro spec. Ours is rated at 265hp; I think the Eurospec is 286hp. As mentioned above, the car has an abundance of torque, basically always at hand. It has a different sound. From the cabin it growls; from the outside it is rather quiet. My mileage is as shown below. Thats an average of 70% city 30% highway. The best I got over a mostly highway trip was 37.1. I think it is capable of around 40mph, but haven't had a series of all day driving on the motorway. People with around 50K or so on the odometer have had a combination of injector and carbon buildup issues and so other emission-related issues. No final consensus on cause or remedy. Some thoughts are (1) drive it hard; (2) have intake cleaned (i.e., walnut-shell blasting) at around 40k; (3) use the best fuel you can find; (4) maybe use a good fuel additive (but be careful which one you pick because our vehicles do not have a water separator/remover).

Frankly I love the car. I drove the 335i sport and thought it was great, but wanted the diesel. As has been said, you can really turn the thing into a monster if you want for not that much money. In the US the max cost just for the tune alone would be under USD 1300. And you can get some of the reputable piggyback plugins for under USD500.

They are pretty reliable Kev mate, nothing really to worry about apart from the boost hose issue.

Is this for you or a friend?

hi, i bought an 09 335D two months ago, chopping in an 06 335i. inital impressions, whilst good, are for me mixed. i find the initial longer gearing a bit of getting used to, and admittedly miss the I`s earlier turbo bite. using sport gets aruond this to some extent, and provides almost ballistic accelleration from 1500 revs or so. on a motorway overtaking at say 70 is near instantaneuos, the car just surging effortlessly past, well anything. i do mostly town/low mile driving, but bought it because i thought i`d be doing much more soon. DPF may be a problem if i don`t, mine has 23500 miles, so previous owner didn`t average much either.i also have , ithink, 225 19" wheels, and have crashed into various holesrecently, so that may be trouble also.MPG whilst better than the I is poor, 23 aruond town, but here at least diesel is cheaper than super unleaded.i suffer from a foot injury due to a car accident and find the throttle heavy compared to the I, prob. not an issue for you.power delivery is linear compared to petrol, but once you get that, it certainly is awesomely quick.for me though, petrol slightly more fun. enjoy.

They are solid but there are a few things to be aware of

The actuators on the turbos can stick leaving no boost. Doesn't cause damage and they are replaced under warranty. Almost all 335ds get this at some stage. Mine were done and the vacuum pipes as I pushed for them to be done under warranty.

The red boost pipe can leak mine never has again a simple fix

As with all diesels the dpf can clog and fail early if you don't monitor temps. If temps are ok they can last 120k

If the engine runs too cold they can fail after 50k

I've monitored temps for the last 2 years and I've noticed them fall from 86, to 83 to 80. This happens as the thermostats gradually stick open letting too much coolant to flow. Again not damaging but if the temps fall below 78c the dpf won't purge, clog up and fail eventually/early.

I changed mine before this 78c cut off point so try to check running temp via hidden menu. Mine were done at Darren wood for 220 quid. Now runs at 91c solid instead of 80 and they even tested my dpf back pressure for me and its only 4mB at idle and the upper tolerance is 20mB - so good running temps and you will be fine.

No other issues I'm aware of that are common.

[rsmallwo]

red boost pipe - common but cheapish

turbo actuators - not so common, costs £4-500

autobox failure - rare but megabucks

dpf pre 120k miles failure - uncommon, can be removed and run without for a few hundred or a new one is a grand+

fuel breather pipe - rare, only on pre 07 cars, £300

[zltm089]

cheers guys...

gona do some reading on the red boost pipe and dpf...

been on here long enough to know about the mighty torque of the 335D ;-)

[mistryn]

Mine is the M57 engine, I think the turbo wise they are pretty strong as they are not electronically controlled unlike other models - they operate by vacuum/actuators

Main things to look out for -

Red boost pipe, look just below the airbox and shine a torch through. If there is signs of oil on the outside of the pipe then it can be a simple fix/expensive. Cheap fix would be to replace the top and lower seals, all in about £14 from BMW and can be done DIY if you have ramp/jack. More expensive would be to replace the pipe all together (only advised if the original pipe is split) as it is circa £160.

IMO the above occurs partly due to the oil breather pipe not being replaced at intervals. Even though BMW say the newer type oil breather is a lifetime product, it can get blocked imo and cause pressure to build up and oil to leak around the pipe/inlet manifold
http://www.e90post.com/forums/showthread.php?t=699581

Another common problems is actuators, there are 2 for the turbos and one EGR. the 2 turbo actuators tend to fail at some point due to the heat build up around the area, parts alone are circa £140 and couple hours labour time to fit. While you are there you might as well get the vac hoses replaced as again these do perish due to heat

EGR Thermostat/main stat - these are the common faults for poor engine running/economy and DPF problems if not monitored. Good old boffins at BMW did not see fit to incude a temp gauge so to the uknown driver they would not know the engine temp = poor running = engine not warming up = dpf not regenarating = DPF woes. again parts is circa £70 plus coolant and couple hours labour time (again DIY possible)

Manifold Absolute Pressure sensor (MAP) - this often gets overlooked when there is a hesitantcy at around 2.5k revs, cheap and simple to fix

I loved the torque or my 335d, the auto box is a bit lazy though. I had red boost hose done and vacuum pipes done under warranty. Apart from that it was bullet proof and it had some right stick that motor. Averaged 32mpg with remap. Ran a 13.3 at Santa pod, beaten by mega with a 13.2.

Mega's best was 13.3 mate.

As has been said running temperature is important to DPF regeneration, but it isn't the only reason DPF gives issue. A lot of the issue is short runs and incomplete regenerations, or just no conditions to regenerate in daily use.

It is one reason I've gone back to petrol, the times I've overshot on trips, to get a complete regeneration in the 330d, doesn't sit well with me. Anything less than 15 mile trips are not really long enough to suit these engines.

What sort of driving and conditions are you going to be using it? Note that regenerations take place every 300 - 600 miles and need about 8 - 10 miles (once hot) to complete. Winter time that can mean around 10 miles ahead of a regeneration even starting, so 20 miles (at the right time) to keep issues at bay.

Great engines, but think it over, as the petrol engine may be the more suited for your use.

bloody hell....


Guys do you know if these issues apply to the 320d as well???

DPF issues can be common, later N47 2.0d engine doesn't have the same EGR setup as the M-series engines, so a bit more reliable for ECT it seems. But depending on what build period, N47 can have other issues including timing chain failures, which can trash the engine.

Another issue with non ideal DPF use is oil dilution. Guy from my local recovery garage was telling me that DPF issues are now one of their biggest failures across the makes. Local use of diesel engines is not a good idea. He recommends shortening the service intervals to a lot of their customers, and advises customers to get driving, give the engines a chance. Worst case, he has drained 9-litres of diluted oil from a 4.5-litre sump, due to ECU trying to get a DPF regeneration. Has seen a con rod through the crankcase, due to oil dilution and engine going on to self destruct, and has a special area at their garage with fire protection equipment for forcing regenerations. BMW are not immune from these extreme issues.

Use the diesel correctly and there are few issues, but get it wrong and many are cursing the day they moved to 'economical' diesel motoring.
