1992 Mercedes-Benz 500SL Problems

Faulty Mass Air Flow Sensor Causing Erratic Engine Operation and Poor Fuel Economy

A faulty mass air flow (MAF) sensor can cause erratic/rough engine operation and fuel economy issues. Since this sensor measures the actual amount of air entering the motor, when it fails, the engine control module (ECM) takes the wrong information and delivers incorrect volumes of fuel to the cylinders.

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.

Emissions-related ports in cylinder head may clog

Ports in the cylinder head related to the emissions air injection and EGR systems can clog; the cylinder head should be removed and the ports cleaned.

Seriously awesome car. One of the last real Mercedes before the cost cutting accountants and Crysler took over. Feels like its made out of a piece of stone, the quality is awesome and it's seriously quick. I've had Bentleys, Porsches and tuned Sierra Cosworths and this is as good as any of them. The only problem is that it is a total money pit. Parts are really expensive and it's a very com...
As our family (kids and grandkids) walked out of the local pizza restaurant, we passed a red 500 SL. My husband and I have been shopping to replace a 96 mini van with 280,000 miles on it, and have looked and tried about every car out there. Go for gas mileage? comfort? But imagine his surprise when we gave him a set of keys and told him it was his! He is in heaven, and I will drive that min...
Bought this car from Mercedes dealership in Omaha about a year ago and love it. Certified mileage 27,400 and the vehicle is in mint condition inside and out. The sticker price of $99,750 in 1992 came as a shock and is the reason why this baby performs and looks like a world class sports car.
