The turbo is controlled from the APC (older models) or Trionic engine management system (later models) by a elecroMAGNETIC vent (MAGNETventil in Swedish, don't know that they called it in Norway.) It is usually mounted near the radiator and has three tubes (leading to the wastegate) and two wires (from the APC/Trionic) connected to it. If it fails the turbo regulation will not work. Broken elecroMAGNETIC vents is a common problem on some model years but I haven't heard of any common problems for the 1999 9-3s. The price for the elecroMAGNETIC vent is somewhere around US $230 or so. > As far as a turbocharger not responding quickly enough, that's > a very vague problem.

If the elecroMAGNETIC vent is broken the wastegate may be stuck upen, or half open, and that will certainly create a problem for the turbo. > or exhaust leak, your turbo is already doing all that it can. ..and dumping most of its efforts through the wastegate. > But, regardless, the problem is not 'magnetic' in any way, > shape, or form. Quite strong words there. -- Goran Larsson hoh AT approve DOT se I was an atheist, http://home DOT swipnet DOT se/hoh/ until I found out I was God.
