Hello, I would be grateful if someone could give me their views on the following: Just picked up my 2005 Galaxy 1.9 TDi from the garage, once home checked the oil level out of curiosity (on level ground, one hour after parking up). The oil level was a good 1.5 cm past the recommended MAX mark on the dipstick. The manual clearly informs you not to overfill as this could lead to catalytic converter problems. Is this a real problem or am I just being a bit over protective of my beloved car? Thanks very much
