W210 E320 CDI fuel leak

[maddog]

The car is a 2001 chassis number WDB210xxxxxxxxxxxx

Ive had a problem with the engine stumbling a little and a smell of diesel , stripped the covers off today and it looked like the glow plug leaking but its actually the item pictured, its a rapid dripping when the engine is running , probably accounts for the stumbling

What is this thing called and what does it do ???

I presume i need a new one , there was a small plastic tie that may have been connected to the cap but this had broken, could this be a symptom of something else???

Get the new one and put it on, I had the same problem, its prone to go.
Its not easy to change because its a big pipe that goes round the front as well. The part is a valve.

Theres not much room around the front so be careful.

 

[maddog]

so does it come with the pipe ??

It has p/n A611 078 0340 on it which seems correct

What is it called and what does it do though???

 

[Cosworth]

not sure whats it called buts its some sort of valve, even the plastic broke on mine and fuel was dripping.

Its comes complete with a long pipe. and If I remember correctly it branches into two pipes.

Low fuel pressure is measured there.

 

[maddog]

is it a bleed valve though?? , if its just a diagnostic item couldnt i just blank it off for now???

 

[maddog]

No stock at the stealers , on order .

Apparently you could buy it without the pipe but that option has been discontinued it now comes with the pipe and is £23+vat

I've ordered 2 and will try and seperate the valve from the pipe as that makes the job much easier

 

[maddog]

christ this is soo difficult , managed to un-connect the pipe but there is some kind of clip in an inaccessable place and i cant remove the pipe.

need a mobile mechanic now in the West Berks area

Wish i'd never started the job!!!

I thought it was some sort of engine kill?? you can change just the white plunger on those so you dont have to remove the pipe.

 

[maddog]

the pipe goes hard over time , i very much doubt it would be leak free even if you could change the valve

Not the whole valve just the plunger and i do it all the time.
