The R Class holds the distinction of being the first full-sized, multi-purpose vehicle produced by the German luxury automaker, Mercedes-Benz. This sedan has been touted as a stylish and sporty ride and Benz fans are quick to agree. Sometimes, however, the owners of the R Class do encounter problems that require the help of a trained expert.
Some drivers of the Mercedes R Class have reported that the MAF (or Mass Air Flow) sensor has been known to malfunction and fail at times. The result can be a noticeable difference in acceleration. This part can be removed by the driver and cleaned in order to improve its functioning capabilities. If the MAF sensor still fails after you have attempted to clean it, then you may be required to take your vehicle in and have it checked out by a professional mechanic.
Regardless of whether or not the sensor is working properly, if you are getting indications that there is a problem with the MAF sensor you should investigate further. Some things to look out for would be difficulty starting the engine or the car stalling out immediately after starting. The vehicle may need to have the MAF sensor replaced which can be pricey.
If you have noticed a failure in the Mass Air Flow sensor of your Mercedes-Benz R-Class MPV, it would be a wise move to bring the car to a nearby German import technician for a complete repair diagnosis. The mechanic will be able to give you a proper written estimate of the all the costs of repair or replacement.
