EGR Location

I Read a past thread on how to clean the EGR tube with a speedo cable. I hooked the car up to OBDII and it read"low egr flow" Where is the location of the EGR valve on my 94 C280?

I have 1990 300E (3.0). Is it possible for you to give me link which explains how to read codes? Thanks

I used a simple Snap-On diagnostic computer that my buddy uses in his repair-shop, we used the OBD II interface to hook it up to the Benz. No need to decipher codes this way as the codes come up 'readable' on the screen along with the corresponding trouble code itself. The machine I used is fairly basic /low end Snap-On, I would think most auto-shops have one. As far as reading codes off of the car and deciphering them, I dont know of a link, but I'm willing to bet that there is one somewhere.

Hope that helps a little,

Standardized OBD wasn't around in 1990. Certainly not OBD II.

I think you can count LED flashes in a 1990 but I don't know how to do that or how to interpret codes.
