Hi! My car is:passat 1.9 PDTDI, 2003,AVB(101HP)(200.000km). This is my first diesel car,i bought two months ago.The car hasn't power under 1800-2000rpm.I push the throttle full down and my car accelerate slowly.At 1800-2000rpm kick out and accelerate very fast,but over 3000rpm the car goes limp mode.2 months ago i had the following error msg: 17965 charge pressure control positive deviation p1557 - 35-10 intermittent. My turbo was cleaned. But now,i have this error msg again. I logged the block 11 with vag-com. The duty cycle is 94,4(2500rpm).What is the problem?MAP?MAF?Actuator?Turbo? Pls help me. (Sorry for my bad english)

Many of the boost lost problems with these diesels are due to a leak in the charge hoses (large diameter). In the U.S. versions, the hoses have o-rings as seals. Inspect all the hoses to and from the turbo and intercooler for a start.

Good luck!
