I understand this is a common problem causing either poor starting or the engine to die a second or so after starting then taking lots of cranking over to re start.
It isn’t the pipes themselves rather the seals on the ends that go faulty however, the pipes go brittle and discoloured. As you can see below the four new pipes from the MD dealer. (cost around £40 for the lot)
Firstly you need to remove the engine cover by undoing the six bolts and taking off the oil filler cap (5mm Hex)
This is the first pipe, the smallest which is an easy one to start with
To release the pipes press the white clips inwards and pull the pipes out
The white part of the clip simple pushes forwards.
When you remove the pipe some diesel might leak out so it is a good idea to have a cloth ready to wipe up any spills.
This shows how badly the discolouration is, and the pipes are very brittle.
Push the clip in on the new pipe, clean the mating surface, push the pipe fully home and pull the white clip back out to fix it in.
The next three pipes are a little more difficult because they run around the front of the engine. The next pipe that I did was the long pipe that runs along the top.
Please see part two for the rest instructions many thanks.
