Hey guys i need some info... i just finished with the DT BPV, took the car for a ride, and once i came back and checked under the bonnet, i noticed that the engine was shaking more than the usual, so i turned off the car, and once i did that, i heard a blow sound (air i think) and then a sound just like an electric motor moving for a sec or two (all of this hapens just right after i turn off the car).... did i do something wrong?? ... i just checked every connection and everything looks ok... please help me!! :impatient

 

sounds like a blown gasket. I did that when I installed my OCC. The OCC hose was pichined.

 

But the blowing and electri motor sound are just when i turn off the car... and the only gaskets involve with the install, are the horn metallic gasket and the throttle o-ring, i dont think i damaged them during the install.

 

Could the blow sound be more of a air sucking sound from the intake? My old Pilo and now my JCW without the flap has this sound when I shut off the car. What kind of intake do you have?

 

i dont think so..
cuz the blowing sound was probably caused by excessive airs extracting from the intake and electric motor thinge, not sure on that but I do believe its normal cuz i've been hearing it on mine for a long long time..

 

Promini... ok i took my cell phone i recroded the TB/PBV area with it during the turn off... and the blowing sound is produced by the PBV... this is what i belive that happens... when i turn the engine off the PBV opens so the pressure (boost?) is relief.. thats what i belive that hapens... and the little engine moving sound come from that area i belive, i dont know from where exactly.

 

i guess we do have a blow off valve (well some kind of)

 

ok heres the video put attention on sec. 14

 

That sounds normal to me. My car makes those clicking sounds after turn off, even my Mercedes does that. I think it is the drive by wire throttle body makeing the clicking sound. The shaking is a bit weird, is it still doing that?

 

I just drove it again... no hard shaking this time.. maybe the computer getting use to it (on the first drive)

 

Did you reset the ecu per the instructions?

 

yes i did ... ive been driving the car, and so far everything is ok (by the wy, chad from DT said the blowing and the other sound were normal, good to know that)

 

^ ^ ^ what does this do?

 

Fix the Yo-Yo
