As the title really....
I've not had a chance to get under the car to look at anything yet....but since having it mapped I have developed a lovely air leak.
I've used VCDS to check requested and actual boost (Both Std & Modified Maps) and they are both well within the limits of being a few mbar out if not the same when it is boosting. And no codes are popping up at all.
But one second I have loads of boost and then I have non.....the turbo is spooling up nicely but no boost I can hear it escaping at the same time and when I let my foot off the throttle you can hear all the boost dump back out of the air filter. Kind of reminds me of the old FRS with a GenII filter on it but without the big Tish noise.
I've also noticed that after I have had no boost and I let it idle it's a liitle higher at 1000rpm and the exhaust note is very different....then after a minute or so just goes back to idling normally.
I'm going to get under the car tomorrow weather permitting and try and track down the fault....
