I used to think I had problems where there were none & had (and still have) issues with the excessive prices MB dealers charge for service.

Once I got the WIS (workshop info. system - the shop service manual) that the dealers use, I was able to fix most things myself and at least understand what was being repaired by the stealership.

You can get the 2006 WIS for free that covers all models 82 and newer at http://thepiratebay.org/details.php?id=3478993

Now I love my Benz!
