Flat spot @5prm in 5th and 6th
- Thread starter WRN
- Start date
Im too sure but could it be a collapsing hose to the turbo?
I think its happened before on tuned cars?
Or maybe a faulty DV?
Im sure other members will point you in the right direction. /ubbthreads/images/graemlins/beerchug.gif

My car goes quickly from 3000-4500 then i think there is a little flat spot. In higher gears you notice it a lot more then in lower ones. I think when you floor your car, the boost is higher for a little time?
Is this true?

The coilpack delivers the electical charge to your spark plug.
Yes there is a slight flat spot on a standard S3 about 4000rpm before it picks up again.
Diverter Valve (DV) - If this goes u will know about it, i was informed i prolly wouldnt get out of 3rd if it went.
Coilpack - Again u will know if one of these go the car will only be running on 3 cylinders if one goes so it will be running real ruff and u will know there is something wrong.
Air Intake Hose - Flat spot about 5000rpm could be your air intake hose collasping but it is usally a problem with chipped cars (is your car chipped).
Wastegate - I currently have a problem with my car its got a flat spot about 2500rpm and then it picks up about 3500rpm but not properly, it has been diagnosed as the wastegate is sticking.
Mass Air Sensor - Not to sure of the symptoms.
But i would say the Air intake hose if it is chipped.
Are u getting a fault warning light coming on.

it going to be really difficult to explain to the dealer how u have managed to get the flat spot at that point, especially if u do not want to declare the chip to them. My dealer is great, he knows i have a remap and i just explained the problem i was getting and a possible way to fix so he did it.
Does it do it all the time??

Well no, only when I been hoofing for a bit, then not only do the brakes fade badly (and smell) but the flat spot is quite bad. Actually it's only been in the recent heat that it's been as bad.
