Had both turbos replaced last week due to turbine failure causing a whining noise at high revs. This week I am having the DCT gearbox replaced due to a very loud rattling noise during driving. My contact at the workshop says its probably the result of the JB4 and increased boost pressure. Have been running map 5 all the time, anyone else had these problems or know one that has? Any input is appreciated.
As the car is out of warranty this is killing me
and I dont know if the JB4 and increased power is worth it.
