In reviewing the maintenance report on a CL500 that we are looking at to buy from a Mercades dealer, an item listed was engine knock on cold start. In asking the dealer about this he indicated after "researching" the work that it was simply "lifter flutter" which he said is common on Mercedes 5.0 engines. The clatter supposedly occurs sometimes for a few seconds or so when starting a cold engine until oil is pumped into the lifters. Can anyone shed any light on this. The car is an '01, 10K miles, with 1 1/2 years of factory warranty left and then another year of Starmark warranty.
