hi i was wondering if any one could help me basically i have a pd100 polo and replaced the turbo and intercooler with that of the vrs. now im having a problem with the car boosting, i have to press and release the accellerator many times to get some boost into it and then it will move, otherwise its as fast as a 1.0litre micra.

theres no leaks with the actuali pipes but there is an airy sound comming from the turbo i think, its not a whistle its more airy. i also get a whistle from the exhaust, howevere it is decated and remapped so some whistle is normal.

Theres no play in the turbo itself so i dont no what it is. im pretty new to this n75 concept so can any one explain it to me, and how may be able to fix it

thank you

Most likely a combination of miss-matched components. The VNT actuator rod may need to be adjusted to match the turbo vanes to boost and fueling. Sounds like chronic turbo lag.

Hello people,

I am a little curious to find out if my car has a problem?

The Turbo whistles whilst on boost, I have owned the car for nearly 2 weeks, it was pulling like a train before, but now when on boost it seems that the turbo is working but the boost dosent feel like its coming in as it should..

No Engine management light

EGR Valve - Clean

Intercooler pipers connected - Checked

Oil Changed - So cant see the oil veins to the turbo clogged

Air filter changed

Have any of you experienced this problem? I feel like some kind of pipe is not connected, as it only whistles whilst on turbo it feels like the turbo comes in at 2500 rather than 1800 rpm, but im new to the turbo world so I need some help please?

Worth making a trip to the garage but if its an easy fix I would rather DIY?

Thanks again

Hi mate

any update on your problem?

i have had my vrs about a week and getting the same thing i.e. lack of power & a harsher whistling (not in a knackered way just louder), only differance is that when i first jump in it, its ok then if give it a good ragging for about 5-10 mins the power seems to drop a bit i.e. not boost as hard tho you can tell it is boosting still.

its done 17,000 and only three years old runs sweet as a nut in every other way will have a look at work tomo i think.

After investigating further it seems to be just the standard intercooler not really designed for abuse, it apears to be not cooling the air as well as it should until you get a really good air flowing through it, in short bursts around back roads you just cant keep the speed up enough to cool it down.
