Many have.. mostly documented under the various CBU threads. Opinion is it's expensive, it works at treating the symptoms, but fails at addressing the root cause.

From where?! You can only get that kind of pricing if you had a gasser in a group buy.

Melonbread, the unspoken hint here is that the process for our D engine is different than that for the petrol engine, largely due to architectural differences for lack of a better word. Hence, the $250 price likely will not apply to you.

He will need other adapter wands for the 335d as the intake runs are differently shaped than that of the gassers. Once he does his first CBU cleaning on a 335d, he'll double that $250 price point.

I have done it. There are lots of photos close by.
It is a slow, tedious process, but not hard. The walnut blast is just part of the work. You need to send the intake out for cleaning, not blast the valve cover and give that an acetone scrub, clean the EGR, and then have the mass rebalance done to reset the injectors. Change the boost hose seals if they are leaking. You have it all apart anyway and those a just a few bucks. Also change all the easy vacuum hoses, which is cheap when all the parts are already disassembled. |
