Sea Foam is basically kerosene. Doing the treatment has hardly any value besides the smoke show coming out of the exhaust. Its snake oil for profiteers.

We have done several BMW diesels. The worst a E39 530D on 165,000km we removed 900g of carbon soot from the EGR and manifold alone. The performance gains and change in fuel consumption where great.
We will be launching for diesel cars soon and I will be in the position to give more information.

Its only for the vehicles fitted with direct injection Naturally aspirated and turbo.

So on our X35 motors. Is it just the head inlet that gets done, or do you also clean the inlet manifold as well?

The inlet manifold on all X35 cars we have done are clean. There was a specific car that had the turbos fail that we needed to clean out some oil from the inlet and intercooler but that is very circumstancial and not the norm.

So will Cleo check all that on my car before he starts the job?
P.s, i have tried calling Cleo, he is a difficult man to get hold of. Hopefully my email to him will get through!

Nope its conventional injection. Only long term issue with your car is oil sludge in the cylinder head under the valve cover area. I had a good look at one, pity I didn't take any pictures.

Are people using meth showing less build up?

Most people have not used meth on the car from new. The cars with meth generally show worse build up. The reason for this is the meth actually wets the existing carbon and more fumes are trapped against it.
If you look at a average meth plume when spraying and divide that into the cylinders its not much liquid going in to think it is able to clean.
We have done a few cars now that run meth daily and it will be nice to see if they can manage to keep the carbon build up at bay.

There is a shop opening mid month in Jacobs. On the N55 I recommend it gets done around 60,000km for the first time unless the car is chasing records and needs all the help it can get.
I was doing some reading on this the other day...
it is a real problem with Direct Injected engines with no real solutions at present besides cleaning every so often...
there is talk of producing oils that will limit this buildup but no word on if it is even possible...
what is agreed is that DI is going to become the standard engine configuration and this problem needs to be solved to make DI reliable and efficient... would be really funny if water injection held the key to fixing this

Hi
My Cooper S has 56 000km and the oil looks like this inside. The car is about one month out of motorplan and just started smoking excessive white smoke.
Do you think this is carbon buildup as well? The dealer says this is normal.
I understand it is now after warranty period, but is the dealer not being negligent for not picking this up and bringing it under my attention even if they dont cover this as a repair?

I cannot comment in raged to the white smoke, carbon build up on valves has not caused white smoke on the 200 odd cars we have done to date.
If what you are showing me is the oil filler cap then it is normal to a extent for cars with a deep recess in the cap to have some carbon collection whichnis basically oil fumes that have solidified at the highest point.
In regard to deposits on your valves they will definitely be there causing performance issues both in power and fuel consumption.
