HIGH OIL CONSUMPTION BY REMANUFACTURED ENGINE

I PURCHASED A REMANUFACTURED VW 2.5TDI ACV ENGINE FROM REMTEC, THROUGH AN APPROVED WORKSHOP, WHOM ALSO INSTALLED THE ENGINE . THE ENGINE HAD A 1YEAR/100 000KM WARRANTY ON. SOON AFTER THE YEAR EXPIRED (AND THE WARRANTY) AT APPROXIMATELY 30 000KM THE ENGINE STARTED CONSUMING OIL. THE ENGINE HAS NOW DONE 53 00KM AND CONSUMES A LITRE OF OIL EVERY ****M. THE APPROVED WORKSHOP HAS ASSISTED TO TRY AND SOLVE THE HIGH OIL CONSUMPTION PROBLEM, EVEN BY FITTING A RECONDITIONED TURBO, BUT TO NO AVAIL. I HAD REQUESTED THE APPROVED WORKSHOP TO CONTACT REMTEC AND DISCUSS THE HIGH OIL CONSUMPTION WITH THEM. I WAS INFORMED THAT REMTEC REP**** THAT THE WARRANTY PERIOD HAD EXPIRED TOO LONG AGO AND THAT THEY COULD NOT BE HELD RESPONSIBLE.
