    Hi,

    My brother bought a passat tdi 130 (2001), but its got no power in between 2k-3k, after that its ok, but not as it should be.

    Did a scan with VCSD, 1 Fault Found:

    17965 - Charge Pressure Control: Positive Deviation
    P1557 - 35-10 - - - Intermittent

    Where would you start with this? Has anybody else had this problem?

    sounds like turbo
    check vac hoses to the turbo and egr valve and the vac hoses along the bulkhead
    check for air leaks on boost hoses and intercooler
    checkoperation of variable veins actuator
    if all this ok
    rebuild/clean turbo
