Hi guys,
My Freebie 1 td4 auto has developed a whistling noise when the auto box shifts or you let off the gas quickly while under boost almost like a blow off valve. as well as a tendency to go into limp mode with a check engine light while cruising on the highway around 130km/h and as soon as you reduce the speed, the CEL goes off and it goes out of limp mode. No Fault codes......
i have serviced it, and replaced all the filters, as well as all vacuum lines, and two of the turbo hoses, the others is still in good nick.
If anyone can please give me an idea of what to look for i would appreciate it!
