  1. Turbo "pinging" noise

    9-3 Sedan, Cabrio '04+, Combi, 9-3X Workshop
    I have a 2004 9-3 with the 2.0t. 94K miles. I recently had the timing chain, tentioners, guides and water pump chain replaced. Both chains are tight with very little slack. The car runs fantastic except for one thing, When I accelate and the turbo nears the red line, I get a pinging noise...
