70/30 hwy/city. My commute is 37 miles each way with most of that being high traffic highway.

Carbon build up issue yes or no? Yes

Additional info:

Msg from BMW tech: "swirl flap linkage was binding and a large amount of carbon build is present"

I bought my D in June 2012 with 20k on the odo. I did nearly double that in the 6 months since.

With that in mind, I did some Internet searches (most pointed here and 'fest) and when the SES returned, I asked the tech to check for carbon/oil build-up or metal filings as that many parts dying in succession sounded fishy to me.

Here are the codes, dates, parts and comments from my 3 trips leading up to and including the carbon build up removal. The text has been reformatted by me to be more readable. Fault codes and things I thought important are in bold.

Complete test plan for faults and complete inspection for leaks with smoke machine. No air leaks present. Per test plan, replaced charge air temperature sensor, cleared fault memory and drove vehicle overnight.

Rechecked faults and found 3FF1 fault returned. Per fault data, inspect air pipes for oil residue indicating air leakage. Found oil residue on both charge air pipes.

Complete test plan again and select air leaks as fault.

Replaced both intake charge air pipes: Intercooler to EGR and Intercooler to turbocharger then cleared fault memory and test drove vehicle again. No faults returned

----------------------------
40,024 miles

Summary: SES back on due to swirl flaps binding, incorrect air flow through manifold

Service Notes: Intake manifold swirl flaps are binding and causing incorrect air flow through manifold causing air mass fault

VOR intake manifold for Tuesday / Fedex failed to deliver on Tuesday

Connect Battery charger to vehicle and complete vehicle test. Fault stored in DDE: Air Mass Fault. Complete test plan for fault. Test intake air temperature sensor and mass air flow sensor. No Fault.

Smoke test engine and intake system, no leaks present.

Removed engine covers and intake manifold to inspect swirl flaps. Found linkage was binding at some spots

Ordered intake manifold.

92575 - Installed New intake manifold
51372 - Cleared fault memory and test drove vehicle overnight

I'm racking up about 8k miles per month right now, so things should happen fast!!

Any ideas why this light came on??

It's probably because in my mind I know I paid over 50K for the car and feel if I sell it for the 28K its worth right now I'd be annoyed for a few years. I just came back home from a two hour visit to a local Audi dealership to test drive some cars. I was very close to signing the paperwork on a new S4 but ended up walking away. I realized I'm just concerned and should not do anything. I like to keep my cars for 150-200K miles before moving onto another. Will my 335D make it? Probably not.

The 335d's problem: My 2010 335d with 43K is in the shop having its head replaced for the third time. The only reason I took it in was for the check engine light coming back on over and over. Yes, I've had all the recalls done except this new one I keep reading about regarding the torque? The service advisor said there are no open recalls on my VIN. I drive this car 35 miles a day with a good mix of highway and city. I fill up at Shell which offers a higher cetane (I can't remember if it's 45 or 48). I drive hard on occasions and normal during traffic.

After having the EGR update done to my car I assumed this problem would be resolved.

Sorry for the venting but I'm annoyed with BMW and this car. I'm also thinking about selling the X5D i purchased for my parents just because it has the same engine. The days of diesels running past gas engines is long gone with all these new emissions and low cetane. I'm starting to think my 2010 328I will outlast my 335d.

My question to everyone on this forum: After having your EGR update done have you had your head replaced due to carbon buildup? How many of you are worried about this issue after the warranty period? I have an extended warranty but what about after that? I'm angry about purchasing a car that is somewhat has a short life.

Oh, and after talking to my tech he suggested I change my oil more often. How the heck would that help with carbon buildup?

On a side note. I wish bentley would make a service manual for our engine! When you look up information on the 335I or any older e46's you have people posting "How to's" left and right. On our cars its mostly "crap, its getting a new head"

My 2009 335d has only 24,000 kms on it but two months ago they replaced my air intake manifold due to carbon build-up. Thankfully I had bought extended warranty a few weeks before that because it would have cost me almost $2000 after parts/labour. I only owe $3,000 on the car so right now I have no real issues and love it but I do know where your rage stems from. Trust me. I know.

If issues persist, I know of a local guy that can do a DPF delete. I'll do the whole removal of EGR and right down to the urea if I have to.

Like I said though, could be anything and nothing too serious like getting into limp mode due to the hard acceleration.
