When my Antara 2.2 is cold and started the turbo is louder than when it is up to operating temp. It does not sound abnormal I just wondered if anyone else noticed this. I haven't had the car long and it's been in for some warranty work doing and I just want to make sure it's right before the warranty runs out. The warranty work was 2 x bypass valves, one on turbo and other on inlet manifold I believe. You thought would be appreciated.
Its just the normal turbo whistle type noise only slightly louder, certainly nothing un toward. Its as if it may be some kind of cold start operation. Goes completely after a couple of miles. Car runs find and turbo if boosting ok.To be honest its no real concern just wondered as i would kick myself if it developed itto something serious and warranty expired.
