Possible high pressure pump leak - 2003 2.0TD4?

Hi there,

I'm relatively new to the site and wouldn't be great with motor vehicles so I am after some advice. I'm based in Northern Ireland.

About a month ago I noticed a pool of fluid under the drivers side - fairly close to the front wheel, just under it. Not an overly large amount but enough to leave a stain on a new patio'ed driveway for my wife! After a week or so of keeping an eye on it and smelling it I came to the conclusion that it was diesel.

I started the landy and took a look underneath; and there it was coming out, started a drip, then got slightly heavier. I took the car out for a spin and came back and the dripping had disappeared. This has happened every time I took it out, starts as a drip, then a small stream, then stops once driving begins.

I took it to a local mechanic who was very busy but took a quick (30 mins or so) look at it. He seems to think it was a leak at the high pressure pump. He said it needed special tools to get at it. He also said a high pressure pump was expensive and that it would be better looking for a second hand pump.

Anyway he said if it's not affecting performance (which I don't think it is, it's going well) that I should continue to drive it until he gets a chance to source a second hand part...

Has anyone any thoughts on this. I'm just a bit worried that especially in the current weather it could leave me stranded if it died out - also I can't park it on my drive which is always a worry...

Any advice or experience on this would be great.

Not many places the HP pump can leak from.
Check the LP fuel feed and return pipes at the HP pump, which you can see. These are rubber elbows retained by jubilee clips. Check both ends.
There is an O ring at the face seal between the pressure regulator and the HP pump which may have failed.

sounds just like mine been doing it for the last 3 years (must get it done) only in the winter its probably the seals in the pump you can get them replaced all i do is start the hippo then drive off straight away after short while it will should stop leaking as the pump warms up

Thanks guys.

I can't really check due to the snow and as I'm not home from work until dark...

My dad has some mechanic equipment so maybe during the thaw when I am home at Christmas I can check it. It's going fine at the minute and like I say once I get moving it stops - its just a pain having to park it on the street all the time. As long as I know other

Will let you know how I get on...

Click to expand...

Seen a few like this, leaking from one or more of the covers. They only leak when cold then expansion seems to stop it.

Can be repaired cheaply if you can remove and replace a pump. Same fault briefly covered here.....
