Turbo boost.......problems

[wastegates]

Little by little it seems that every time it is better after reviewing sensors, reached 1.35 bar ....... I still look where there may be small problems.

I would like to ask you an important question to see if I understand the operation better.

Is it possible for the barometric sensor (F96) to work in conjunction with the throttle potentiometer? , That depending on the F96 the potentiometer of the accelerator to the maximum varies the % in VagCom?

Thanks

No it's not

We continue the same, do not just raise the pressure well, I do not know what else to look at ................ testing today at 4th speed at 60 km / h I have hit the maximum and I Arrives at 1.3 bar, besides that it does not rise as quickly as before ..................... I have reviewed the barometric sensor again and it is fine.

Only the MFTS is left but I find it strange that it only lowers the pressure a little, if it was bad it would arrive until the pressure of the spring of the WG no?

Tips ?

Thank you

Hi friends, I put a couple of videos of the reaction of the car, although to better still I notice that it is not going well at all.

In 6 gear at 80 km / h maximum accelerator.

Here it looks perfectly good, in S2forum you do not see the video, which can fail

Hi again, I'm starting to get a little tired of the car, I've changed MFTS and it continues the same (but does not improve), but now the temperature needle marks 105 Cº when the fan comes in and VagCom tells me that there are 94 Cº when the fan Is started ................................. before with the old sensor marked 90Cº the needle of the frame and the Fan was put into operation.

Is this new sensor defective?

Have you tried cleaning the maf connector and inside the maf itself?

Yes, I even changed the Maf for another to do tests, and checked the electrical connection.

Now I have worried the new MFTS, I do not know if it is defective because it marks the temperature higher than the old one.

I need some help

Thanks Mike

I have just gone through the same trying process. Mine lasted the better part of 4 months. Mine ended up being the MAF. I had swapped MAFs with no avail. I finally ordered a new MAF and all is great. The car starts and idles better as well. I didn't know I had two knackered units. Have you tried a MAF off a properly working engine? Or perhaps you could try yours on another engine?

[wastegates]

Thanks for replying, any help is welcome, I put another MAF of an S4 (AAN) that I recovered from a scrapping, I also have an original MAF of the car that years ago I changed for safety although I think it worked well.

Also the MFTS is worrisome because it marks much more degrees than before and this worries me, today I will check the temperature with a laser thermometer to ensure that it corresponds with the control panel.

The input of the fan is independent of the MFTS not?, Because after having changed the MFTS the fan according to the marker enters almost 100 Cº and I do not think it is real.

Thank you very much for answering ThatGUY.
