Mercedes Benz C220 CDi 2002 - leaky injector #

Posted by Liam Hall on March 19, 2012, 9:54 pm

Year of Manufacture *: 2002 '52
Engine Size and Code *: 2200

Hi all,

I have just had this car recovered to me, after a phone call from a 'weekend mechanic' owner.

Seems he had a leaky injector that he tried to tighten and since attempting that repair, the car wont start.

I have had no time to scan for codes etc, but did turn the car over and it is spurting fuel from around the injector.

My question is, if someone would be kind enough, having removed the injectors, do these need coding upon refitting?

They look the same type as in the citroen hdi's, that dont need coding.

I think I may need Tony from AP to get the blighters out mind you!

Thanks in advance

Liam.

I have done several of these Merc CDI injectors now.

They often start to blow around the seating, and you need to recut the seat before refitting with a new sealing washer. Also they tend to get stuck in the head and need a special puller to remove them. I have ended up with a slide hammer adapted onto the puller to remove these.

And then often the screw for the clamp will pull the threads out of the head. So then its drill it oversize, tap a new 8mm thread in, and refit with a stainless socket head screw.

And if one has gone, repeat the above for do all of them.

And not forgetting new high pressure injector pipes.

Don't be afraid to quote high, because if you do it properly it will take time and care.

I've done a couple (of hundred ) of these now and many have had the threads torn out/off by use of a slide hammer before i got there. like many injectors some are tight and some are loose it's the tight ones that cause the problems for most people. use of the correct tooling always helps though.
