No 1 injector wire black /black brown No 2 green / black brown No 3 green / black green No 4black / red No5 black black / yellow could anyone please answer if the colour coded wires are correct ? and i can,t find any numbers on any of the injectors,my car was running ok apart from the black death but now it seems like a miss or fuel starvish, does anyone know of a cheap mobile diagnostics in doncaster that could solve or at least pin point the problem , thankyou

The only safe way to shut down injectors to check for misfires etc is a suitable computer,if wires are disconnected while running,lasting damge to the engine/injectors can occur and on a Mercedes that won`t be cheap
