Hi, haven,t been on here for a long time. My 2006 Multijet has just received a new MAP sensor and a new EGR valve to try and erradicate black smoking under load.Which it seems to have done. Problem is now that the EML is on (it wasn,t before I started interfering) Code reader comes up with P0235 turbo pressure sensor valve.Also not willing to go above 3000rpm. New turbo sensor on and still the same, and there is a ticking sound/vibrating coming from it when you switch off ignition. I just noticed the old one did the same before I removed it, so thought it was defo shot. Now I,m not so sure.
Any information or help would be gratefully received. Thanks.
