I have purchased this item and had it installed my professional mechanic, this item lasted 30 days and stopped working- since months now I've contacted the distributor and am beein told that I'm passmy return date--- so buyers beware, their products are defective... I've now purchased and oem and no issues just waste of time and money.

I bought this product as i was getting error code of air flow mass sensor. I bought this part and it took me time to install this product due to some other issues and after few months when I installed it the error code still exist. I didn't read the other reviews when I was ordering the stuff. Its a garbage product and I was wondering if someone know about the warranty of this product.

The shipping was prompt. The fit, finish and fit up were good. Instructions were unclear, good there is pictures.

Great product. Codes were immediately cleared. Great savings over Mercedes pricing.Used on ML350 2015.

This quit working after a couple months. Then cost $2500 to have replaced. How do I even get my money back for this part? Who’s responsible for selling garbage parts.
