Fumes in Cabin
I posted this on the other MB forum that we are not suppose to name, so for some this may be a repeat.
I have a 2006 cdi, 170K miles, build date 02/06. Whenever I come to a stop for more than 20 seconds, I start smelling fumes come in through the air vents. When I park my car in the garage, it will smell a lot. I took off the sound dampening covers to look for any leaks, I did not see any.
When I remove the oil fill cap while the motor is running, I can see some vapors come out of the opening. This also resembles the smell more than the typical diesel exhaust smell.
My thinking is that it may be a partially clogged EGR valve/system. From the two MB forums I belong to, I thought 95-percent of the EGR issues had to do with model year 2005 cdi's. I may be the 5-percent of the 2006 cdi's that is experiencing this.
My question is, what are the symptoms of a clogged EGR? At this time no codes are being thrown, or at least no check engine light. This is something I will let my indie check when I get the time, but I just wanted to see if anyone has experienced this before.
