David, thanks again buddy...
I know that there was a recall on the EGR valve on the car. They replaced it three times under warranty. I'm just wondering if the EGR valve has an updated part # and the MB dealer here is just giving us the old part again and again that's why it is constantly breaking. This is the second time after warranty that this thing broke... it cost 300 dollars just for the part!!! well... I'm just glad our babybenz is back in its stall..
