Welcome to the forum.

That's fantastic news.

Kudos to you for actually searching and finding the info that you need to fix the vehicle. Many new members just post away..........

A tidbit for assisting you:

Don't bother with the "search" function on this site. It cannot search more than individual words. As an example, it cannot search "EGR valve". It can search "EGR" and it can search "valve" but not a phrase.

Use google for all searches and put "mercedesshop.com" as the domain name. You'll get to your desired end much faster.
