I have this error on VXDIAG VCX SE Renault Clip with an old renault car is it normal? saying probe is not compatible with the car.
It is normal. VXDIAG and some other J2543 passthru devices are not good on older K-line Renault cars.
VXDIAG supports Renault (CAN BUS models) from year 2005 to current.
If need to diagnose older Kline Renault, get a CAN CLIP interface or universal scanner instead.
