Hi,

 

    Special situacion, car runs ok, but with some hesetation, very conservativ.

    On Vag everything is just fine, exept one thing. In a block 115 mesuring asked vs real boost computer asks for very strange presure, fluctuacting up and down. Second thing there is no boost spike, and presure is fluctuating all the time, little. Computer does not asks for more then 0,68 bar ...

     A/F ratios are just fine, no missfires,maf is fine, ignition , coils, plugs, O2 readings and tests...everything.

     One more thing car had LPG which is completly removed...

     Tested with N75 to WG actuator unpluged only thing I get is spike, but fluctuation again, tested DV it is fine.

     Any ideas... Here is the log from vcds

Edit, I cant post grid from VCV

i have a similar prob wit my car the boost feels to be going up and down up and down. and the skoda workshop did not find out what was wrong but i started to look at it my self and i noticed that my car leaks in the downpipe its so little leak that i just heard it while i was holding my hand to see if there were any leaks from the wastegate actuator but it was not and i heard something else barely noticeble but i held my hand near the flex thingy and felt exhausts came at my hand 

 

tomorrow, friday it will go to a workshop called maptun and see if  it is only the leak in the exhaust that makes my car go like this or if its something else to

Thanks mait.

I do have some new mesures and tests done. There is a posibility of fuel pump problem, not big, but pump going off...

Need to make adaper for fuel line and mesure actual fuel presure during full throttle.

Please, share any new info.

yeah okeej  will do,

 

 got a call from maptun today and they couldnt take it in until thursday 24th september so can give more info after that

Thanks again.

Anyone else???
