Fuel Injector Repairs

Mercedes Fuel Injector Repairs are something we perform every day for our customers.

Leaking fuel injectors is one of the most common problems on Mercedes diesel engines. There are two types of fuel injector leaks on a Mercedes diesel engine and we can repair both easily. 

'Black Death'

The usual type of fuel injector leak is commonly referred to as ‘Black Death’. It refers to the messy carbon buildup that fills the space around the fuel injectors, pipes and wiring. It’s caused by erosion of the tiny copper washers that seal the fuel injectors to the cylinder head. Partially combusted diesel fuel escapes from inside the combustion chamber and sticks to the top of the engine as a black carbon substance.

This problem is most common on Pre-2006 Sprinters and Vitos. The Mercedes fuel injector repair process requires special tools for removing the fuel injectors and grinding the sealing surfaces. The good news is that the fuel injectors can usually be salvaged and reused, which reduces cost.

Diesel leaks can come from the following areas:
