I have volvo v70Xc 2002 with b5244t3 engine.
There is bulb lamps in dash.
I wont to change dash to "new" from petrol car 2003 model year. There is led light.

I try flash and eeprom from dash model year 2004 but in dose not work in my car.

I think that flash from car model year 2003 with led would work.
