BMW 335i E92 injectors failure
Engine problem with a 335i E92 N54.I thought it was the High Pressure Fuel
Pump thats slowly dying(very known problem) but it turned out to be the
injectors of cilinders 1,2&3 that were failing.
BMW N54 Carbon Removal
Carbon build up on the intake valves and intake ports of the cylinder head
on a BMW 335i (N54). This video shows what this condition looks like before
and after carbon removal. These large carbon deposits will rob the engine
of power, performance and fuel economy. Sport Motoring, in Decatur,
Georgia, offers a service utilizing the factory tool, to remove these
deposits and restore performance and economy.

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
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.

BMW N54 Turbo Rattle Clanking Noise Caused By Failure Turbo Chargers
This video show how to check to see if you have the turbo rattle that is covered under an extended
warranty for 8 years 80,000 miles on many BMW's with the N54 Engine. The
rattle is caused often by a worn pivot bearing in the arm that controls the
waste gate valve. When it does not closes correctly the rattle can result.
This can also cause a check engine light and the 30FF Boost pressure too low fault.
BMW Turbo Charger Rattle Problems N54 Engine (BMW Extended Warranty For Turbo's)
This video has an example of a turbo
charger that is rattling so you can hear the noise and includes some
diagnostic checks you can perform to determine if your N54 engine has this
problem. BMW has increased the warranty on turbo chargers to 8 years 82,000 miles on all N54
engines which would be on the 135, 335, and 535 vehicles.
This video also shows a turbo and
demonstrates one failure of the pivot bearing causing the rattling.
