Hello all, first off I want to apologize for the noob question, read through this thread and didn't see my question answer directly. My question: Is this a normal maintenance (50k, 75k etc) that BMW performs to vehicles? I'm assuming no.

BMW won't pay for it. It's the design of direct injection. No fuel passes by the intake valves, so you don't get any of the cleaning action. I first did it at 90k and mine were pretty bad. No tune and highway miles though. I had rough idle since 60k, but now it's gone.

if you are going to invest in this i recommend purchasing the oil catch can from burger and installing it after blasting but before turning the car on... will prevent needing to do this again so soon.

I just had my 335 cleaned by Luther at Flemings Auto in Hyattsville, MD.
Luther is a good guy and he did a great job - from start to out the door in 2 hours for $430 bucks. I highly recommend this to anyone with the N54, especially if you have an "upgraded" air filter and running a tune, you are going to get A LOT of gunk in there.

I started misfiring and now all is clear...

Hells - how many miles did you have on your car when you got this done?

so Fleming's does this? Good to know. They're the closest place to me (save for a dealership) that hasn't turned me down. I talked to Luther about something else recently but didn't think to ask about the valve cleaning.

Luther, any update on willingness/ability to perform this on the d? As stated, I'd be happy to pay for the internal inspection if you find that my car truly doesn't require any cleaning, but--as a DI engine with EGR--I honestly doubt that will be the case.

Thanks for your help!

Fleming Automotive (Luther) Walnut Media Intake Cleaning N54

I can see there have been many posts about this, but I really feel I have to add another. I was pointed to this thread by a fellow N54 owner after unsuccessfully chasing the cause of a very annoying misfire issue (and spending a lot of money in the process). At 38,000 miles my 2008 335i (N54) developed the dreaded Cylinder 5 misfire, resulting in a cylinder shutdown and shaking like an off-balance washing machine, throwing the SES light.

Leading up to this, I had noticed that at half-throttle in 3rd gear or higher, I would get the sensation that my clutch was slipping. Over a 2-month period it got progressively worse, to the point that I could trigger limp mode and an SES light on command by giving half-throttle in 3rd gear or higher, and giving more throttle at around 3,000RPM.

Long story short(er), I kept getting the P0305 (cylinder 5 misfire) error code. I replaced all 6 spark plugs with OEM, the #5 coil, and the #1 injector (was faulty). Local dealer did a key read and the injector part numbers where not known to be bad; HPFP had been replaced in 2010 prior to my ownership as part of a recall, and ECU was updated to the latest code in late 2012.

I visited Luther this morning after scheduling time with him over the phone. He performed the walnut media intake cleaning while I watched. You've seen the pictures, so I won't post mine.

Bottom line, no joke, the misfire completely went away. All hesitation disappeared, only silky smooth strong pulling power no matter what gear I was in, nor what level of throttle. Idle is now smoother, throttle response is better, and a strange clicking noise at idle disappeared. This was performed at 39,000 miles.

By the way, Luther is very friendly and courteous, and knows what he is doing. He also charges a LOT less than area BMW service shops and dealers.

Hey, Clem, are you back in action on this? If so (and youre not averse to oil-burners) let me know as I am overdue on the diesel.

Thanks!

Excuse my noob question but how would an oil catch can prevent the need for carbon cleaning? Am I reading that correct?

I would consider purchasing this before carbon cleaning if it would prevent the need to do the cleaning again.

I t will help to remove some of the oil in the intake system but will not alleviate the problem.

Without a tune, most likely you would not notice the difference. But as stated before, without this cleaning, you will start to get misfires and a multitude of other problems.

Highly recommend Luther, he did a great job. I also added a catch can to eliminate some of the oil.

Props to Luther and to anyone who can complete this process in 2 hours with a nice clean and through finish. I just completed mines and it took me several hours. Got mines pretty clean......all the way down to the valve seats. Had to change out my OFH gasket at the same time though. I completed the last two ports much quicker once I found out how to maneuver the gun. Still.....2 hours is very quick. BTW, this was performed on a 07 335i with 56k miles.
