Hello,
I have a 2003 Audi A3 which I have recently bought. It keeps telling me that coolant is low. I went to Halfords and they gave me Comma Xstream G40. The owners manual says it requires G12+ though, I think that there is probably G12+ already in the car. Will I be ok to mix the G40 and the G12+ in the car? Or will this damage the car?
Thanks!
