If anyone is still reading this, Mercedes require that you use their DEF. I think it's called DEF BLUE. Was talking to a service man at the chev dealership and he said "don"t complain about our price of DEF, a Mercedes has to have their brand and costs about $75 to fill up" True???
Absolutely not. The dealer told us to buy it at Walmart, it's cheaper. If you take your vehicle in for service they will fill it and charge you that much.
We had a warranty issue that was showing exhaust related. We filled the DEF tank across the street prior to taking it in for service so we would not pay them to top it off.
