Review on Premium Black Fuel Tank Cap: Gates 31849 OE Equivalent - Guaranteed Quality! by Joshua Pilla

Don't waste your money on this product. To fix the P0244 MB 2008 C300 trouble code, you must first replace the gas cap and then disconnect the battery for 30 seconds. I did this and the light stayed on. My wife took the car to the dealership and after a $300 diagnostic test found out the problem was the gas cap (which I bought). They replaced the cap with an MB certified gas cap (priced at $42) and the code was cleared and the lights went out. So not only did I lose $25.78 on the gas cap, I lost $300 thinking it was compatible.
