hi
wish to gain more understanding ref the turbo i didn’t know if by me sharing some information that i’ve since gathered if it may be useful to others ,
along with if that’s ok to pick the vast knowledge within this section please
i currently get intermittently an overboost issue, which i suspect is the VGT vane sticking
Engine TDV6
no smoke and will go into limp mode just over 50mph
didn’t realise that u could buy the VGT vane assembly and cartridge
found an excellent post describing how to replace the turbo and got me thinking , as u look at the turbo if whilst in situ it could be split to gain access to the VGT vain assembly without having to remove the entire turbo
my forward plans are
1) to indeed double check for the full movement of the actuator arm, ( have had the software upgraded so it motors the actuator arm when i turn the ign on ) , clean and grease arm with ceramic grease after , then to check for any split hoses , no smoke
2) remove and replace the turbo intercooler hoses and whilst removed to use an endoscope to try and gain a better knowledge of the inside and if the VGT plate are full of carbon
3) if the plate is full of carbon to use a turbo cleaner or oven cleaner
4) see if there’s any end float on the bearings
these are the links ,etc , i’ve found which i hope may help in one way or another
