![]() ![]() Although I don't suspect a leak around this boost tap, it will return the car to "stock" config without the boost tap between the supercharger and throttle body intake. Was thinking that I could take out the boost tap and return to stock, and re-measure block 436 for the manifold pressure. I did have to install a boost tap between the throttle body and the supercharger output when I put in the gauge, but that was about a year ago, and things have been solid since then, up until a few days ago when I noticed the issue. I also noticed I am not hearing the same sort of supercharger whine I was used to.Īssuming I read low boost/pressure in the manifold what steps would you all take next? I am not too familiar with how the bypass/diverter or etc work on the supercharged engine in the B8 S4. I am going to have access to a VAGCOM/VCDS tonight to read block 436 to read the absolute manifold pressure, to make sure there is really a problem. I thought maybe the gauge is off, but my one grease monkey friend says its not pulling as hard as it used to.

As you guys get into more open road KMs I'm sure you won't be disappointed with the gearbox matching etc. Around town the size of it isn't really going to give you Golf R feelings but on long trips this is a very good GT type car and the DCC makes it even more adaptable. ![]() The real beauty of this motor is the torque everywhere though and how it revs out too. Still overall while it feels like it takes a while to get going, sub 6 sec to 100kph is still not slow for a large wagon that is under half the cost of an RS4 and has more toys inside. More than half pedal pressure it drops gears and holds it until redline then changes. Under slight pressure, it won't even change gears it just uses torque to speed up, a 3rd of the travel, it drops a gear and speeds up it that way quickly while changing up gears. It is very sensitive to how far its pushed down to when it holds gears in drive. Selecting sport mode does up the revs at idle about 200rpm probably giving the extra boost mentioned above but not sure if makes any difference really as the gears not changing so early have more impact than the extra 200 rpm does overall.īut I find sport mode gear box wise a PIA and now have learned how far pushing the accelerator makes the car behave instead in drive. The AWD just helps once it starts slipping and you keep your foot down and then you don't see the flickering orange light in the two AWD carsīut in saying that mine definitely has less than a second's hesitation from a standing start and I use the auto hold everywhere although if you don't completely hold the brake down it will just sit there on the foot brake without auto hold engaging too i.e no green brake light on the dash. ![]() I don't think a GTI or Golf R feel any different to the Passat in respect of the DSG response being common in all of them. The AWD system isn't instantaneous and you can feel it working it out. Sent from my SM-G930F using TapatalkThat is sort of right though, but my understanding is that it doesn't power all 4 wheels unless it needs to so is really just pushing the front wheels most of the time.? In mine, if the front wheels are on loose metal or wet road markings it slips until it grips. It's a heavier car and all that inertia would be quite taxing on the gearbox if it were to have to transfer all that power instantaneously to all 4 wheels. I think you're spot in with the DSG limiting itself. ![]()
