This DIY (Do It Yourself) How To Video shows how to use a media blaster and walnut shell blasting media to clean the carbon (decarbon) from the intake ports and valves on the BMW and MINI turbocharged engines.. We will be performing this service on an N54 6-cylinder. The N55 will be similar. This applies to the 135i, 335i, 535i, X5 and similar models.
It is important to put the vehicle in “sleep mode” before beginning any work. This powers down all modules and computers, allowing the various sensors to be disconnected without generating faults in the systems. Perform this step as follows:
1) Place the vehicle in the position where it will be worked on.
2) Open the hood and the driver’s window. Close all other windows, doors and trunk.
3) Turn off all systems and accessories and remove the key.
4) Move the key at least 20 feet away from the vehicle.
5) Apply parking brake and place transmission in NEUTRAL (manual transmission) or PARK (automatic transmission)
6) Wait 20 minutes.
7) Once the vehicle is in the sleep mode, do activate any electrical accessories or systems (besides bumping the starter, as shown), close the hood or open the doors, trunk or windows.
With the introduction (in the US) of the N54 twin turbo 6-cylinder engines in the late 2000s (135i, 335i, 535i, X5), and now the N55 single turbo, N20 4-cylinder turbo and all the rest of the turbo and naturally aspirated “N” 4-clyinder, 6–cylinder and V8 engine family, we are seeing the effects of heavy carbon build-up in the intake ports and valves. BMW has even recognized this and has implemented a “de-carbon” program for many of these engines. The N54 and N55 3.5 twin and single turbo engines are the most susceptible to the heavy carboning (so far). BMW dealers will be happy to perform the de-carbon service for a fee of $600 to $800, and up. The de-carbon service involves removal of the intake manifold and blasting of the ports and valves with walnut shells, using a special fixture (plus a media blaster and a shop-vac).
The de-carbon service is really not all that difficult, but does require some special tools, as noted above. Bavarian Autosport has developed a full Do It Yourself (DIY) program for the de-carbon service on the N54 twin turbo engines (more to come, just ask us if you have a different model). We will provide the special adapters, media blaster, walnut shell media, replacement gaskets and full video instruction. The media blaster kit is available for purchase or rental.
