Hello There - I Am The Proud Owner Of A 98 C280 & Going By My Research This Car Is A Bit Of A Problem To Its Owners . So Far I Have Changed Plugs,MAS,Timing Sensor,recharged Ac, Replaced Breakes & Rotors,changeD Vibration Damper . My Current Problems Are #1 Rough Idle - Otherwise Car Runs Fine (have Read Others Advice On This Problem Is To Replace The Boots On The Coil - Where Do You Get These ?- Having A Hard Time Finding Them ) #2 Oil Sensor Is A Little Weird 1st It Says I Am Low On Oil Then It Flashes & "dings" And Says I Have To Much Oil !(where Is It & How Do You Change It Out?) # 3 Now My Low Fuel Lite Flashes With Gas In The Car ? #4 And Of Course The Check Engine Light Came On Recently & Stays On Now - I Have Checked All The Fuses I Could Find & I aM Going To Try & Check Out The Egr Valve Today . Other Than This The Car Is Ok - Any Suggestions (i Have Already Thought About Dynamite Or Turning It In To A Submarine My I Think My Wife May Get A Little Excited ???thanks Al
