You've got a new or clean air filter installed? Not a K&N or other oil impregnated one right?
Assuming so, I'd check the electrical connections and make certain they're good, then spray clean the MAF again.
Does ******** sell OEM MAF's or inserts? MBDOC has said previously the VW inserts sold by some suppliers for use in MB's while similar are NOT the same, and that the Chinese parts should be avoided.
