So my purge valve has been ticking VERY loudly as of late. I can hear it from inside the cabin, and outside it is very obnoxious. I am currently planning to follow the cleaning instructions PDF I found on benzworld in hopes that it alleviates the situation.

However, I am wondering how I can clean the EGR valve. My car has felt a little sluggish as of late, especially at highway speeds so I'm giving this a shot. I have tried searching up and down for a tutorial, to no avail.

Anyone have the details? Would appreciate it greatly!

BUMP! Anyone?

Just take it out and clean with brake clean and a toothbrush if needed worked great for me on another car. That said I have read that if the EGR valve is having issues cleaning really only buys you time. No clue how true that is though.

I would agree the EGR valve starts to go and then just keeps on going.

Why do you suspect the EGR for the power loss/sluggish feel?

Could be plugs, wires, dirty throttle body, dirty MAF, Dirty air filter, bad gas,......

The list of things that could be wrong is very long for a sluggish feeling car.

I suspect EGR because the previous owner (as well as myself) have taken care of almost every suspect. Plugs were done late last year along with wires, I replaced air filters this past summer, oil change done, checked brakes for any that may be stuck, I've changed gas (BP, Exxon, Sunoco) and nothing. I haven't tried cleaning the MAF because honestly I'm scared, Lol. I've heard nothing but horror stories. I believe it was recently replaced though, I'll have to comb through the service receipts.


Where is the EGR located on this car? I'd like to at least look at it to see how it looks.

Thanks!

BUMP! Still looking to figure out where the EGR is, maybe check it to see if it's dirty or not.
