If you do a full scan, MES will say if an SGW is detected.

I use MultiEcuScan Multiplexed with an CanTieCar adapter. Never any problems. No need for coloured adapters.

When I checked in the engine data it was set as 1.3 multi jet (which it isn’t ) so I changed this to what it actually is I.e 1.4 8v
If I change it back will it cause any other issues?

Probably best just to leave that as is.

SGW won't hide functions, it will block you from doing any writing/programming
