w124 e300d injector removal

Trying to cure poor cold running - next step is injector testing - Do I need any special tools to remove the injectors? It is a 1995 model with 170k miles.

I used a deep 27mm socket made specially for the Bosch injectors so that the leak off pipe nipples don't get damaged.
It was a Snap-On socket.

The good old 27 mm deep socket won't work on the newer diesels like the OM606. You'll need a special MB socket that you can get from a dealer. This has been mentioned several times on this forum.
2004 VW Jetta TDI (manual)

Past MB's: '96 E300D, '83 240D, '82 300D, '87 300D, '87 420SEL

Is this true for the old W124 style of car - there are no electrical connections to my injectors.

Though you may have done this alreay but ive had a few w124 and w210s towed into my shop with similar problems from other shops who have tried countless things (IPs, injectors, filters, ect..) ive found that the fuel hoses relax up on the fire wall and suck air, seems to only affect 606 and 604 engines, and only cold. Just grab the hoses and see if they will spin on the steel pipes on the firewall on the drivers side. If so replace them all from the lines to the fuel thermostat in the head.
Keep us posted
Good luck

Thanks Ben; are you referring to the clear diesel lines? What do you mean by the "firewall". There is an electrical temperature sensor in the head linked with the fuelling system - have you ever seen any problems with this unit?

Do you have the right part numbers of these fuel hoses for my 95 E300D; it is really hard to figure out which ones they are from the MB parts diagrams?

Thanks for your advice I am going to change these hoses when I get the inlet manifold off.
