Thread: Remove and clean injectors 200TDI

Servicing injectors on a TDi are in the realm of 'professionals' - they are a precision instrument of sorts, and not somthing serviceable in the field (So to speak). Some can be rebuilt - new nozzles and shims, but you need specialised testing equipment to get it right. Generally take them to a diesel injector specialist. If there is black soot around the injector, the copper sealing washer might be leaking, and you can replace that easily enough - be careful with the injector pipes, you do not want to damage them. If the fuel spill return lines are leaking, use Mercedes diesel return line (From your local diesel mechanic) and use medium cable tie wraps to secure them.
