What is loud tapping/clicking noise coming from engine?

Asked by Oct 27, 2012 at 07:58 PM about the 2011 Mercedes-Benz E-Class E 63 AMG

Question type: Maintenance & Repair

Just started today.  It speeds up as rpm's increase.  Will it damage engine to drive car across town to mechanic?  

1 Answer

Noise gets louder once warm? This model is common for worn tentioners that are controlled by oil pressure and as long as the noise isnt a clunking that can be heard in all conditions exept under cruising load. Towing might be a good idea.
