Hi need advice on my w212 taillight playing up. It’s working some time. Some time only right side doing this. It’s a faulty light or some fuels issue????

If both sides are sometimes not working (but at different times,) it soulds like a wiring system issue. First you might like to check the connections at and correct installation of the lamps.
