Looks like I'm diving under the car once again tomorrow. Looks like hole. It's at front of resonator. Not sure where is that hose going.. I will try to put some small rubber and one hose clamp to seal the hole and try it. And mostly under the load you can hear whooosh. While standing maybe if I put 4500 rpm and not every time. Probably only under the load in 2-3-4-5-6 gear cause hole is small. |

Trick of the camera...fibre reinforcement webbing of the hose...you had the flash on so created a shadow.
It all looks fine and dry from here. That's the round shape of the stainless clamp about 6 or 7mm back from the end of the rubber boost hose and is obscured by the driveshaft. If you had a leak there you would see an oily residue, around the point of exit, absorbed by the dust. What you can't see is the other side of that boost hose, which goes up to the turbine outlet of the turbo, where great pressure is generated, and it could be split and out of sight. Can you get your hand up there to have a feel about? And can you perhaps see any evidence of oil residue around the intercooler? If not you may need to take it to someone, with a trained ear, to pinpoint exactly where the pressure is escaping from.

You ruin my day, I was happy that I found the problem haha.
Probably I must remove heat shield from exhaust manifold and try from that side (under the bonnet). I will write as soon I check. Thanks for effort. Love this forum |

Okaaay guys, game change. I recorded video but probably cover mic and there is no sound.
It's not under the car I would say My lovely wife gave 3500 rpm and let throttle few times. I was surprised: there is on air filter housing some small door When let throttle, door are opening and air is going out. Do somebody know what tf is going on? I change air filter 2-3 days ago, so it's not filter problem. I will order new boost sensor now just in case. I will record later again and take few pics and first of all remove filter housing and see what is going. |
