Hooper, what kind of price are you hearing for a new intake manifold? Retail is ~$800 according to realOEM. I would think cleaning a "walked in the door" manifold should/could be done for $200 or $300. I know, I know, pipe dream but I'm still going to ask.

I really hate just about everything about F30 328s. After 9000+ miles, I feel qualified to make the assessment.
ouch. i guess i should not be complaining as i've only had a loaner for just over a month.. been told the intakes should be produced on 2/8.

I remember it being around $700 from online locations. I would be surprised if the price is less than that, even though it ought to be more in the price range you figured ($200-$300) or less. If the cleaning included the valve cover, which is also plastic with intake ports in it ($300 online) they would be starting to get somewhere, but honestly unless the cleaning includes the head, valves, and all intake paths, they are spinning their wheels

"Carbon cleaning is approx. $1500.00 plus taxes, this includes sending out the intake and valve cover to clean out the ports, and cleaning the 12 intake ports for carbon and all new gaskets."

This is what my SA said.

well, that says to me that the cylinder head is cleaned. For $1500 it could be worse, $1500 every 50k miles as a maintenance issue is not horrible if you know you have to plan for it.

I was at the dealer today. I asked their top master tech if they had anything for dealing with carbon on the D. Without hesitation the answer was a resounding NO.

On top of this you need to add the cost of cleaning or replacing the intake manifold. Also if not in the $1500 you will need to add a few $hundred for new head bolts. They're not reusable on a gas engine and doubt they are reusable on a diesel with even higher compression.

My buddy who works at an indy shop just texted me this:

"We are starting to see a lot more diesels at the shop now. Lots coming in with frozen urea reservoirs and EGR valves stuck open with carbon!"

Anyone know the torque specs on the intake manifold cover?

Edit: I think it is 15nM/11 lb-ft

I read that a bit differently. I read it as removing the intake manifold and valve cover to send out for cleaning and then cleaning out the intake ports on the head, but not actually the valves or anything else on the cylinder head itself.

From the latest replies, this may be a BMW Canada only thing, or perhaps just a service that this particular dealer is using, since they are sending the parts out for cleaning.

I asked my SA who I'm friends with about what would happen if I have the carbon buildup in the 50-60K mile range. He said he doubts I'll have it by the way I drive however if I do they'll clean the intake and heads. I asked again clean and not replace, and he said no they'll clean it that they've been doing cleanings on these for a while now here.

The dealership is Nalley BMW just outside Atlanta in Decatur, GA.

Is it certain that he wasn't just lumping the process for the gassers in with the diesels even though the flow pattern is different?

No the guy's name is Bevan and he's a hardcore car guy (drive a '13 M3). I stop by and we BS car stuff just for fun. He gave me the entire rundown on the diesel before I even bought it. He wanted to make sure I knew about all the carbon/EGR issues they can have. We recently spoke about the possible carbon buildup if it happens and what they would do to fix it. Being a huge car guy myself and having above average mechanical knowledge I trust this guy and what he says.

Good, well since I live just north in Maryland I know where to go to get my CB cleaning done. Just as long as it doesn't happen when you guys have freezing rain or an ice storm.

I was just talking to a svc manager whether they had any official recommendations on how to avoid that build up (they don't), but one thing he did mention (and I don't know how true that is) is that the diesel fuel below VA is generally better bc "there are less additives in it that are mixed in for the heavy equipment in the colder northern states". Certainly an interesting hypothesis..

I did the prepaid maintenance plan. I expect that this maintenance will be included. It is no different than changing dirty oil and filters.

Yea except this isn't a BMW maintenance item. The car is going to need to be under warranty to get BMW to cover it. Induction system cleaning isn't part of the BMW maintenance plan. Re-read your extended maintenance coverage and you'll see what is and is not covered. I agree on all cars they should do some sort of induction cleaning at 50-60K miles but when BMW's planned service life is 100K mile they don't care. Its up to the owner to maintain their vehicle to last beyond the planned service life.

I'm currently having my Dad get this from his (http://www.bgprod.com/catalog/diesel...#bg-product-13 and http://www.bgprod.com/catalog/diesel...#bg-product-12) BG Rep so I can try it out on my car. I don't have the carbon issue yet but I prefer (assume you do too) to do preventative maintenance so I don't have problems down the road.

its quite the racket, if you bring it in for issues coming from carbon buildup they try to tell you its a maintenance issue, but if you have a maintenance contract the carbon cleaning isnt considered maintenance

Interesting find. I wonder how effective it is. The idea is obviously sound. Let us know how it goes!

There is an art and a science to getting your car maintained.
