Sorry sir the late update, fitted the kit, reset the error code and the pump is completely silent! Still slow to get off road compared to the p38 but does get there quietly now! However I now have some more issues!!
I have a strange rumbling sound at low speed when I take my foot off the revs, I have checked props etc nothing seems knackered there, I’m thinking perhaps the diff has lost a couple of teeth, (has the exact same thing happen on my old p38) same kind of rumble sound, is there anything I could be missing, I did check the rear top bushes which seem fooked as when you jack the car up on the suspension leg (air bag lower mount area) so you keep the weight on the air bag, remove the wheel and the top bush mount can be moved by hand with ease! Could thing cause a rumble and the entire hub rumbles round, if you jack the car on the sill so the suspension hangs down, there is no play but the bush looks heavily distorted then? Seem to do nothing but throw money at this car! Oh and I have a new gearbox fault aswell now!!
