Hi all,
I've recently had a few issues with my GL320 including the exhaust pressure sensor failing and the EGR valve triggering a code. My mechanic replaced the sensor and the EGR valve appears to need repair, the plastic part is coming loose and disconnecting but I've got it working temporarily. Looks like to replace the EGR valve is like $1,000. Was doing some research and sounds like some people delete the EGR using Green Diesel Engineering or Malone. I'm not really sure how that works but sounds like programming the ECU.
I happened to purchase an Autel MP808 last year to troubleshoot several issues across my cars and I know it can do some programming of the Mercedes, but I've never ventured into that side of it yet. I don't want to create more problems by experimenting so was wondering if anyone has made EGR or other edits using a tool like that or if the only option is to pay one of these tuning companies or if I should just spend the $1,000 on a new EGR valve. My mechanic did also mention that Mercedes was running a campaign on EGR valves for 2009 and newer models, but not sure if there would be a way to get Mercedes to include my 2007 but thought I may also try and make a call and see what I can learn on that front too.
