Q: MB SLK 230 1998 fuel light flashes and throws a code. Replaced all the emission parts.

When the engine is cold, the viscosity of the oil is higher along with the internal bearing clearances in the engine. As the engine warms both the viscosity of the oil lowers and the engine bearing clearances can increase dropping...

Depending on the conditions, 25 miles per gallon is not too bad, especially in the winter. Gas companies are required by the government to change the mixture of gas in the winter to decrease vehicle emissions. When they make a...

Hello there, thanks for writing in about your 2005 Mercedes CLK350. This is not an uncommon fault. The most likely cause would be the neutral safety switch (https://www.yourmechanic.com/services/neutral-safety-switch-replacement), transmission linkage, transmission range switch (https://www.yourmechanic.com/services/transmission-position-sensor-switch-replacement), or low transmission fluid level (https://www.yourmechanic.com/services/transmission-fluid-service)....

You may not be able to remove the arm rest without removing the entire door panel (https://www.yourmechanic.com/article/how-to-replace-a-car-door-panel-by-robert-tomashek) first. Depending on vehicle, you may only have to remove a couple screws and the door panel will lift straight up and off....

The occurrence of code P0900 is probably not related to Service Campaign 15B22 (https://static.nhtsa.gov/odi/tsbs/2015/SB-10058725-1330.pdf?_ga=1.163152181.88204048.1469644261). That service campaign was initiated by Ford because TCM's were failing to set codes (illuminate the check engine light) when faults occur. Your situation is the...

Check for diagnostic trouble codes. Overheating has the potential to cause head gasket leaks and valve and piston damage. You should measure cylinder compression to first be sure that the engine is basically mechanically sound. If cylinder compression is normal,...

If the alarm is sounding even when the security system is not activated, that points to a controller issue and such will have to be diagnosed. I would recommend requesting an electrical components diagnostic (https://www.yourmechanic.com/services/electrical-components-are-not-working-inspection) and the responding certified mechanic...

it sounds like you may have a transmission problem as the whining sound indicates. This usually happens when the transmission oil pump filter is clogged. When this happens, the whining sound will usually be proportionate with the speed, meaning as...
