Has anyone priced the carbon cleaning (walnut blasting) at local dealers? I have an 07 335i with 50k and I suspect carbon build up. I'm getting a slightly rough idle despite new plugs and HPFP.

Any idea if CPO covers the cleaning? From what I hear it is nearly impossible to throw a code from bad buildup.

+1 Neighbor. My car needs a carbon clean as well.

When I had my 335i. I did a carbon cleaning at a shop for $150 if I remember correctly. Was not walnut or seafoam. They had the system that hooked up to a connection in the head and exhaust, and ran chemicals. I did alot of research and found it and saw that a shop I trusted, Hillmuth of Columbia, had it. I reset my mpg and ran it for a week prior to it, about 1k mile, and an after test. Engine ran smoother and I went from 22 mpg to 25 mpg with my mix of city and highway driving habits.

I am in desperate need of carbon cleaning as well and everything I have read on the subject says that chemical cleaning doesn't work.

+4 I need it to at 56k now....and cannot get the pictures of gunked N54 valves out of head.

I was thinking of approaching BMW of Sterling and ask them if they'd give a "group" rate for walnut blasting. They typically charge $800-$900.

I'd be willing to pay ~$500 for the walnut blasting.

Whaddya think?

Guys,

My BMW tech buddy can do this here at my shop for $400. His method will not include walnut shells but I can guarantee the same result. PM me if you're interested.

so i know in theory all this cleaning is a great idea, but realistically, has anyone noticed a difference? MPG can be iffy depending on driving conditions and driving style so im taking that with a grain of salt

mr5 did a dyno and apparently gained 10whp... the thread is here somewhere but it could be a factor of the conditions

What actually will he do? Is this chemical, some hand cleaning?
$400 may be a good price depending. My dealer will do a chemical cleaning for $200 and local shop for $150, so it would be nice to know.

i have a friend who charges 295$ and told me takes 3 hours. He did my brother-in-laws M3 and no more check Engine light. i don't know if this is related as i am not mechanically inclined in such things. But if anyone on this of the State is looking, I have a source. PM me for his number. Thanks!

You are in, Rich. I will confirm tomorrow, but there is a good chance that we can have the shell blaster here on Saturday. I'll report back once I know for sure.

[O HELLA BMW]

how many times has your bmw tech buddy cleaned the valves on the N54?

As long as they get clean, the method doesn't matter to me. That stuff is nasty looking from the pics I've seen of other cars.

Adam, as we talked about earlier, put me down for the 12 to 1 slot.
