The most-asked new question in diagnostics: does an ENET cable work on an EV? Yes — modern EVs are more Ethernet-based than petrol cars. Here's the list, the price, and the safety rules.
Search volume for 'ENET cable for electric vehicle' keeps climbing because owners assume EVs need something different. The opposite is true: with no legacy CAN-era electronics to support, EV platforms were designed around automotive Ethernet from day one.
Jaguar I-PACE, BMW i4/iX, Mercedes EQS/EQE, Audi e-tron and the VW ID family all expose DoIP diagnostics on the same OBD2 pins (4/5/12/13) as their petrol siblings. The same $29.99 adapter works.
