Why Does My Mercedes-Benz Need an Upper Cylinder Clean?

There are a few ways an upper cylinder clean can be carried out on a Mercedes-Benz:

Spray the cleaner into the throttle body where it gets sucked into the intake manifold

Pump the cleaning agent into a vacuum hose or pipe that enters into the Mercedes-Benz’s intake manifold

Remove the spark plugs and spray the cleaner into the spark plug holes

All methods can be done separately or performed together within the same upper cylinder cleaning task. There are various cylinder cleaners available and your mechanic will determine the best cleaner and method for your Mercedes-Benz.

Carbon build-up on Mercedes-Benz cylinders can cause pre-ignition, due to the heat of the carbon deposits, it leads to an engine misfire. When Mercedes-Benz engines are firing at the wrong time it’s not healthy and can cause the following problems.

The Mercedes-Benz will eventually respond poorly, idle roughly, noticeable engine knocking and loss of power on acceleration. Fuel consumption could increase and the Mercedes-Benz’s engine light may come on. Some of these signs can be subtle and easily go unnoticed, that’s why it’s a good idea to add an upper cylinder clean to your Mercedes-Benz’s service on a regular basis.

An upper cylinder clean will generally cost in the tens of dollars up to the hundreds, it depends on how dirty it is, the time taken to clean and the type of Mercedes-Benz. An upper cylinder clean is a quicker and cheaper alternative to pulling an engine apart to be cleaned. In some cases, a can of spray might not fix the problem and the Mercedes-Benz’s engine might need to be pulled apart, which can cost into the thousands.
