OK, EGR Valve is under the air intake housing, between the engine and the air filter and it has a vacuum lin going to it, correct me if I am wrong.
On the top of the valce is said INS 25 (25 was below the INS).
On the side the part number was 002 140 03 60
and below that it was 135700 1530 XXX (couldn't read the last 3 numbers.)
Mercedes Benz said that my car was no affected, so I don't even know why I am doing this! But I thought I'd be safe.
