oil sludge problem
 

I am the original owner of a 2002 VW Passat with 97,000 miles. Last spring, after a 50 miles road trip, my oil light came on with the message stop. Luckily, we were blocks away from a VW dealership who checked the oil and said we were a quart low, filled it up, and sent us on the way. We thought nothing of it except that I had never been low on oil before and the error code never reappeared until last month.

We were notified of the oil sludge problem with this engine ,but i still can't make my car recover,help?

Well sludge build up shouldn't really be a problem providing your using the correct spec oil from a recognised company when oil changes are done and at the correct interval.
