I Have Tried The Steering Wheel Trick Many Times With No Results. While Car Was Under Warranty They Replaced The Electro Hydraulic Control Unit/shift Valve Body, Steering Angle Sensors, Turn Rate Sensors, Level Control Distributing Valve And The Complete Engine Control Module, All With No Results. So I Agree Totally With Lowanover That This Problem Could Be A Bottomless Money Pit. Since Mine Is No Longer Under Warranty Guess Ill Have To Live With The Ads Lamp Coming On. Obviously This Technological Masterpiece Is Too Much To Handle For Mb Dealers. I Cant Imagine What Repairs Like This Would Cost If Not Covered By Warranty. Its Not Even Spending The Tons Of Money For The Repairs But It Dont Seem Like They Can Diagnose And Correct The Problem Without Rebuilding Half The Car!!! Thankfully Mine Doesnt Have Any Adverse Driving Conditions When The Lamp Comes On So I Can Live With The Problem. The Darn Light Just Aggrevates The Heck Out Of Me Because Its Irritating And Mb Cant Seem To Solve An Ongoing Problem!! With Only 42000 Miles On My Car Whats It Going To Be Like When It Has Higher Mileage?? If Anybody Out There Has Any Suggestions Id Appreciate Them!! Leejxxxxx... Glad You Have All Your Problems Solved. I Didnt Think It Got Cold Enough Around You To Put On The Hard Top For The Winter! I Just Put Mine On Too. It Gets So Cold Here I Never Take The Car Out In The Winter So I Dont Even Know Why I Bother To Put The Pano On!! Its Nice But Youd Sure Get More Use Out Of It Out There Than I Do Here...lowanover Good Luck And Post If You Have Any Luck With That Ads Issue....thanks All
