Ever since i bought my car it had an EGT fault code. So when i decided to overhaul my car a replacement was first on the list along with a brand new turbo. I bought a second hand one off ebay from a buyer who assured me it came off a car with no fault codes but alas...im getting the same fault code up again. I have trawled through the forum and it appears that this EGT is quite important. I have checked for continuity back to the ecu and im getting 12v at the blue/yellow wire so its not the wiring. From what i read, not having a fully working EGT is bad news right? could it be the reason why my original k04 had a cracked housing? and where is the best place to buy a replacement?
