PurpleS500

Hi,

I have an w166 ml63 been running great , until... went do replace front brake pads and oil filter housing leak, had those both replaced. Got car back and since then I'm wasting much more fuel then normally would and the suspension became harsh as I'm riding on sport plus mode always even though it not selected .

the dealer says no issues found, with it as its a performance car its normal gas mileage and suspension is build that way, however I had this car for awhile despite no codes it not driving normal nor the suspension is normal., other shops see no codes, I scanned it no codes.

Anyone has an issues like this that can relate or any input to guide me right direction.

Thank you,
