I feel for ya bud. No way if want to own this car outside of warranty.

I hate to say it but I'd take bit to the dealer. At least then you have a 2 year warranty on all parts and labor. Not many independents are proficient on the bmw diesels yet.

Interesting that you got the throttle body off without needing to pull tube. I like to do it in part to inspect how much oil is carrying up the charge pipe.

Sorry your issue has went from bad to worse. Good luck with dealer.
thanks man. apparently it could be the red flexible boost hose thats leaked oil- according to a google search. apparently a puma case open about it so im seeing if dealer can look at that.

also i think i misspoke- i had to take the top part of charge pipe off- wher eit connects to throttle body but not the lower part at bottom of engine

yeah man id have to agree with you. no point really towing anywhere else as i also need a courtesy car... so ill have to suck it up and pay the $1k to get egr installed and then another $5-600 for intake manifold cleaning and then who knows what else...

i do have 3.5 year warranty left on the veh but its aftermarket- not from BMW... and thy cover notthing to do with "regular maintenance" which they classify anything to do with carbon buildup.. and nothing to do with emissions.. which is what thy classify the egr valve to being.

Well, right on schedule, my SES light went on at 54,000 miles. I have a 2010 CPO 335d. I have owned it for about a year and the only problem I have had is a leak from the oil return line to the turbo. Fortunately my dealer is located in a town with a lot of wealthy earth nuggets who are inclined to buy diesels, i.e., the dealer repairs a lot of 335ds. To state the obvious, the SA (a very good one) simply stated "you don't own a 335d without a 100K warranty" period, full stop.

Like a lot of other people on this thread, I am car guy and I drive my 335d hard but I also take care of it. The 335d is an unusual, fantastic car...I sometimes wonder how the hell the product development team at BMW got a 425 ft/lbs 3 series approved for the US market. Unfortunately, the 335d is also a unique AND highly engineered car with all the associated problems. Yes, I know they have been selling diesels in Europe for years but there is no doubt that the development of the computerized engine control and the clearly half-assed emissions system did not fully factor in CA air regs, US diesel quality, etc.

When you boil it down, we are all have a variation on the same problem...fuel, carbon, emissions issues. For what it is worth, and as many of you already know, BMW has carbon deposit issues with its recent gasoline engines as well. Cold comfort.

My two cents: politely go into the dealership loaded for bear. Tell them that they need to look at the DDE first not last. If they want to pull the head and replace the injectors, fine, knock yourself out. Also make them look at the turbos. The oil return line and vacuum lines are a problem especially when the car is driven hard. My gut tells me that a lot of 335ds have fouled turbos that will fail.

Finally, do not for one second assume the SA knows more than you do about your car. Avoid getting a young SA unless he is a nerd that appreciates diesels. As in any profession some of the dealer SAs are terrific and many are god awful. If you treat a good SA decently they will advocate on your behalf...if you don't, plan on driving your loaner for several months. Ask to speak with the mechanic directly. You'll be able to tell how much they know about diesels very quickly.

In the next 18 months many, many 2009-2011 335ds are gonna break 100K and lose warranty coverage. BMWNA is not going to be able to ignore us.

well said! keep us posted with your car since your techs will probably know more about diesels than mine up here in canada- not many diesels come by here.

also update for mine- they said the intake manifold needs carbon cleaning- i already had this done. $900 i spent and now theyre saying but we didnt send out the head... we just walnut blasted while it was on engine still???... i was pissed... and not ready to pay to send it out now to do same thing i thought they already did...

also the EGR valve that they said failed? they replaced my EGR back in 2012 already... i said they are replacing that for free since its their part that failed within 2 years... and im waiting to hear back from them- want my $600 diagnosis cost reinbursed. i paid $600 to diagnose and they come back saying its the same 2 issues we already knew about and i already paid them to fix? thats unacceptable

Few days ago I went through every single available BMW SIB for the M57Y, not a single one of them was to address the soot/carbon build up. There were SIBs for DDE replacement. Only one remotely related was EGR vavle update, since the old vavle was prone to sticking from carbon build up.

Either the 335d issue is not "big enough" yet, or BMW NA is not taking an active role since the market for the 335d is relatively small. However they (BMW ENGINEERING) are fully aware of the common issues with the 335d. Regardless, if they don't start to acknowledge this, they can say good bye to the diesel market in the US. Audi and MB make fantastic diesels now.

Even though I can say I have not had issues with the diesel yet, I do have a problem with no AWD option. I have already found my next diesel vehicle when my contract is done and it is not made by BMW.

Dealer just told me the wastegate on turbo is leaking and will be replaced. I guess I dodged a bullet for now. I am going to have them printout the service history as well as all the codes. I want to know what has been done to my car to date. I am little irritated given that I told the younger SA that the car had no low end punch. Very curious to see how it drives post fix.

2011 BMW 335d  [0.00]
I have a 2011 335d with 49000 miles. I haven't driven it much in 2014. I haven't had injectors replaced but this latest trip to the dealer they ended up sending the head out to be cleaned of carbon buildup. I tried with the SA to engage in discussion of getting DDE replaced but SA just said to buy the extended warranty.

Any advice on getting through to them on replacing the DDE would be appreciated. This is my first BMW. I intended to drive it 500,000 miles. Instead it might be my last BMW

I have seen some posts on additives for fuel. Is the consensus that additives will really help to prevent carbon buildup or is it just wishful thinking?

Not all DDEs are bad. It's when the dealer keeps replacing injectors to resolve SES, especially the same one more than once, then it's often the DDE, and not the injectors.

In regards to additives and carbon, I can't see how it will help at all. The fuel (with the additive) being direct injected, is downstream of the intake system.

I'm at 43k miles on our 2011 model and have yet to see an SES. Keeping my fingers crossed. No additives, maintenance by the book except Changing the oil about every 7K miles (I do in between changes myself.)

I think the carbon build up is from the soot (EGR valve) and the oil vapors in the intake (PCV valve). A fraction of the exhaust gas (before filtering by the DPF) is recirculated in the intake. Additive that reduce the soot level may help.

An oil with low volatility (Mobil 1 ESP?) may also help.

Disclosure: This is only speculation from my part!

Macan TDi. With tune it will be close to the 335D power except it will have all the things required to drive on crappy prairie roads, get similar fuel economy and performance. AWD is a must in winter and I like the idea of having a spare tire and not having to think about run flats which are a stupid idea for Canadians.

Just got the car back from the dealer post SES light.

Fault codes: 4873, 4D16

Replaced pressure converter for turbo and vac lines. Not enough vac to acuate EGR flap. Replaced all hoses to vac reservoir. Cleaned metering valve on emissions...metering valve was "caked up".

In any event, not know a lot about the codes above it is now clear to me that the smaller turbo was not providing much if any boost at low speeds. A few months ago I remember thinking the car had lost some of its low speed drivability and there was just more gravely diesel pulling from low speeds. That said, when I jumped on the gas the thing still pulled like a freight train once the bigger turbo kicked in. Long story short I should have been more insistent about having the dealer look at the turbos. The car drives one hell of a lot better around town. Engine no longer feels like it is working at low speed and the power delivery is must smoother and more linear.

UPDATE: picked up my car after yet another $1k bill... although they wanted to charge $2300 but i got it cut to 1k.

-EGR replaced under their 2 year warranty as it was their part that "failed".
-Oil cap was cracked and leaking oil thru it- that was the large oil spill i found on bottom of car.
-carbon cleaning of cylinder head and valve cover
-vacuum hose replaced
-put in stock air filter- the K&N filter they said caused issues...?

picked up the car- drives great- put a smile on my face. im hoping thats the last of the carbon issues and issues in general... but i fear its not. i'll enjoy the car for the time being tho!

--would our car benefit from a CAI system? any recommendations?

What a crock. You should have been charged zilch and gotten an apology for selling you a car with such serious design flaws. This car is about as good an investment as a boat. Wish I didn't love driving the POS so damn much...

Hope your car stays sound from here.

car drives fine still MPG is up and no stuttering on any RPM range which is a positive. jsut tired of throwing money at it. i spent $30k of aftermarket parts on my 350z back in the day and spent less on maintenance than this! and this cars stock!

Sorry man...what a drag. I'll say it again...it is amazing how these 335d chat boards have changed. 18 months ago the bulk of the posts were about which tune was best JBD vs DTUK vs Renntech. Now it is nothing but mechanical issues. BMW has a mess on its hands.
