I purchased one sensor back in late December, and it worked great! After six months, it is still functioning well. In April, I bought another sensor to keep it as a spare part on my shelves. However, when I tried to use it five days ago to replace a faulty MAF (Mass Air Flow) sensor, it didn't work as expected. The car would stall, and the acceleration was sluggish. To diagnose the issue, we scanned the car using a Mercedes Benz SD Connect 4 Scanner. The scan revealed the error code P2004-002, indicating a "B2/5 (Hot film mass air flow sensor): Short circuit to ground or open circuit (P0102)." Although the sensor I purchased appeared to be new, it failed to function properly. It's worth noting that the product description mentioned that the sensors do not come in a box. Considering the price, I wouldn't risk purchasing from this seller again. Instead, I would prefer to pay a little more for a sensor that comes with a box and a guarantee. Unfortunately, since I bought this as a spare part and didn't test it immediately, I am now outside the return window, and I have lost my moneyRead full review

I read reviews elsewhere of product failure of those $25 numbers. Bosch is an Original Equipment Manufacturer, OEM. If you want to do the job once and return the vehicle back to sevice quickly this is the way to do it. The actual work was easy, requires little effort, knowledge and tools. :15 job at best.

Sensors become old before they fail. I changed that sensor on my 1998 ML320 because I though it was time. It required 1 screwdriver and 5 minutes. Since that change I reduced my fuel consumption by 12 %, and the car is much smoother than before. It will pay for itself within this year. A good expense if brand new and genuine. Can't speak otherwise.

I don’t like it because I can’t use it but my car loves it. It came back to life as soon as this Bosch mass air flow was bolted on. No more sluggish, tiresome feeling, so if my car loves it then I guess I do too. Huge difference!

Changing this MAF cured the running issues with my car. However the screws holding the MAF to the housing were not standard security torx but some new variation with a larger center pin. My security torx tool his not fit so I has to change the whole unit. I would have been much easier to change just the MAF itself.

This part was an exact match for my Mercedes and the parts works perfectly. I previously bought an aftermarket and received several error codes for fuel trim which I later found out was common. Go with Bosch only if you own a Mercedes product!
