Mercedes-Benz SLK230 Problems

Mass Air Flow Sensor Failure Causing Poor Fuel Economy and Check Engine Light on

The mass air flow sensor can fail, resulting in poor fuel economy and Check Engine Light illumination.

Repair Leaks From Head Gasket/Timing Cover Gasket Before Oil and Coolant Intermix

Internal and External engine oil & coolant leaks can develop from the head gasket and/or timing cover gasket; these leaks should be repaired before the engine oil and coolant intermix which can result in severe engine damage.

Wire Connector on Transmission May Leak Fluid and Damage Control Module

The electrical connector at the automatic transmission may leak fluid. Over time leaking fluid could migrate through the wiring harness and damage the transmission control module. If that happens a new harness and control module may be necessary to correct the problem.

The battery has been replaced twice. I run it while parked until it reaches 180 operational temp. on days it isn't driven. Yet it will not start w/o the Battery Tender being connected. All diagnostic checks are alright. The front right fender(battery side) was damaged & repaired.

R & R instrument cluster to fix now START ERROR only runs for a second (1 answer)

Took it to a shop and they stated it was the computer under the hood, they said it got wet, which seem impossible they way it is sealed

Ok. I have to brag about my car. I've never thought of buying a Mercedes but my 2000 Ford Explorer XLT is giving me problems. I recently turned 46 and thought of getting a convertible.

The cost of ownership for this car is too much to handle. I am very disappointed.
