Mercedes 190E Problems

The Mercedes-Benz 190E was in production till 1993 and was a small but luxurious sedan with a number of great features for its time. Its specifications included two engine sizes. One was a 2.3 liter, four-cylinder engine with a mileage of 18 miles per gallon in the city and 26 mpg on the highway. The second was a 2.6-liter, six-cylinder engine with a mileage of 17 mpg in the city and 25 mpg on the highway. However, much like any other vehicle, customers may have faced problems with the Mercedes 190E from time to time. Some of these questions are answered by the Experts and listed below.

How much would it cost to replace an alternator on a Mercedes 190E (1993 model)?

Typically, the Mercedes retail price would be over $500 but t a remanufactured Bosch alternator for around $350. In addition, labor charges to test the charging system and undertake the replacement may amount to around 1.5 hours.

Why would a Mercedes 190E be experiencing starting trouble with the car? It starts and then dies repeatedly.

This could be because of a faulty over voltage protection relay that powers the engine management system. When this happens, the owner could have trouble starting the car especially when the engine is cold. Look for the relay in the compartment located behind the battery and examine it for an internal failure. Check for faulty fuses on top of the relay as well. Another reason is if the distributor cap and rotor have become defective. This could also lead to problems starting the car and difficulty in running it.

The driver’s seat in a Mercedes 190E can go back and forth but it doesn’t go back up. What could be the problem?

This seems like a seat switch has become defective. Since the only thing trying to be done is switch the polarity of the motor to change directions, it would help to get the seat switch checked out properly.

Every time the driver switches to a lower gear in a Mercedes 190E 2.3 automatic, the car shifts hard. What are the reasons this could happen?

Get the transmission serviced and check the pan for debris that would be a symptom of internal failure. Change the fluid and filter and then adjust the modulator pressure on the transmission along with performing a control pressure adjustment. Finally, check two other things: the kick down switch under the gas pedal to ensure it’s not pressed down and the kick down solenoid on the transmission.

After replacing the water pump, thermostat, hose and flush system in a Mercedes 190E and find that it still overheats when started and let run for a short while. Why is this happening?

There are a few reasons why this could happen. If the car heats up only when idle and gradually cools down when driven, it’s possible that a fan clutch has become defective. However, if it is continuously overheating, a blown head gasket could be the cause for this. Pressurize each cylinder and check if the expansion tank has any air pressure entering it. It would be better to get a professional to run these tests so that they can pinpoint the problem and fix it as soon as possible.

The Mercedes 190E has many great features and was a good car for its time. Yet, car owners have experienced problems with the car on occasion. While this can often be frustrating, some of these issues can easily be solved by troubleshooting with Experts.
