I requested A&M replace the spark plugs, engine oil, oil filter, left and right front wheel bearings, check entire engine for fluid or exhaust leaks, verify turbocharger operation and perform a cylinder compression check. They completed everything EXCEPT the compression check. There were NO exhaust or fluid leaks ANYWHERE but the original oil filter was a little loose allowing oil to leak, but only when the engine was running. They changed the oil filter and fixed the problem. The 3ngine oil was not mixed with radiator fluid or contaminated with exhaust carbon or fuel. The spark plugs were clean but "old" and were causing a fault Code for "Misfire". After completing everything EXCEPT the cylinder compression check A&M stated the "ENGINE IS RUNNING SMOTHLY"!   THEN A&M COMPLETED THE CYLINDER COMPRESSION TEST AND SAID EACH CYLINDER HAD FAILED THE TEST. EACH CYLINDER WAS RUNNING AT LESS THAN HALF THE REQUIRED PRESSURE AND THE CAUSE WAS EITHER FAILED PISTON RINGS OR A BLOWN HEAD GASKET. A&M RECOMENDED I REPAIR OR RE0LACE THE ENTIRE MOTOR. THEY WENT ON TO EXPLAINE THAT REPLACEMENT WAS LESS EXPENSIVE THAN REPAIR AND A NEW MOTOR / FULLY INSTALLED WOULD COST $12,000.00 AFTER TAXES. PLEASE NOTE: THIS RECOMMENDATION WAS MADE AFTER A&M HAD JUST INSPECTED THE MOTOR AND  PROVEN THE PISTON RINGS AND HEAD GASKET WERE FINE!!!!  
I DID NOT PAY FOR A NEW MOTOR. SINCE THE ENGINE ONLY HAS 80,000 MILES ON IT,  I TOOK THE VEHICLE TO ANOTHER LOCATION AND HAD IT RETESTED ON VIDEO. THE ENGINE COMPRESSION IS "PERFECT". THE TEST RESULTS ARE NEARLY IDENTICAL TO FACTORY SPECIFICATIONS!!!!!  YOUR MECHANICS ARE EITHER INCOMPETENT OR DISHONEST AND GUILTY OF ATTEMPTED LARCENY IN EXCESS OF $10,000.00.  I AM STILL LOOKING FOR LEGAL ASSISTANCE TO ADDRESS THIS!!
