Genuine Xentry ($40,000+) with annual subscription ($3,000+) is brand specific for Mercedes, can provide full bi-directional functionality. For example, among others, SCN, variant coding, adaptations, forced DPF regenerations, etc. Depending on a person's Geek experience and Automobile knowledge Xentry can be intimidating and as many on the forum are fond of saying, in the hands of the inexperienced and negligent can turn your Sprinter into an expensive lawn ornament or garden shed.
I am not familiar with the 808p and was not able to locate its advertisied capabilities. If you can, please share a link.
