DRIVING HOME FROM WORK, ALL OF A SUDDEN MY VEHICLE WAS REVVING WHILE IT WAS IDLE AND AT LOW SPEED, MAKING IT VERY DIFFICULT AND DANGEROUS TO STEER THE CAR AND KEEP IT UNDER CONTROL. UPON INSPECTION, IT WAS FOUND THAT THE TIMING CHAIN TENSIONER HAD FAILED AND HAD CAUSED SERIOUS ENGINE DAMAGE, CAUSING THE PISTONS TO FIRE PREMATURELY. PREVIOUSLY THE TENSIONER WAS REPLACED IN 2014 BY AUDI WHEN THE CAR HAD ~50K MILES AND WAS REPORTED AS A "WEAK TENSIONER". MY CAR CURRENTLY HAS 92K MILES. I BELIEVE THAT NO REPLACEMENT TENSIONER SHOULD ONLY LAST 40K MILES AND CAUSE CATASTROPHIC ENGINE FAILURE AND PUT CONSUMERS AT RISK OF NOT BEING ABLE TO CONTROL THEIR CARS.
