Wow Right then where to start The way you want to go with this first is to forget about the bike pump youl do more harm than good. your landrover friend has pointed you in the right directions but just pulling this and that of hoping for results is not the way forward. Bite the bullet and take it to the dealers to plug it in they can then actuator test on the egr valve,fuel pump etc etc. If you dont want to go down that route then start by checking all the rubber pipes,wires etc. Battery side of the car just behind the fuse box there a black plastic cover remove it and youl have acsess to the solonoids and more tubing. And are you saying the car hasnt had a service in a 130k (your oricinal posting)if so you MUST do a full service with a oil flush and drain the intercooler before you can go any further
