I've just picked up my second 850, this one a T5 which i love but there is a strange whistling coming from the engine under acceleration. From cold it's very pronounced, increasing in volume and 'speed' depending how hard i press the go faster peddle (turbo related?) It quietens down after about ten mins. I've read a few suggestions on different forums but only generic and not related to the 850. Has anyone else experienced this? It's in for a new timing belt in 2 days so if i have some pointers i can give the mechanic it would be much appreciated. TIA Adam
