So I bought a 2006 TDI used and it looks up to snuff on maintenance since day 1, 5k oil changes at VW (probably excessive) - cam replaced at 205, EGR cooler replaced at 205k, Timing belt changed at 190k, DSG tranny and DMF replaced by VW under some warranty deal at 140k. My question is on the coolant that is the only thing I'm noticing the owner before me had a record at 245k that he took the car into the VW dealership complaining about coolant leak. Per the records VW said his "coolant tank had a leak?" and replaced it and did a coolant flush. Now I have the car and still seems to have a slight leak somewhere else because I am seeing the levels decrease. So I search around and buy G12 which is for the 2006 PD. I then for some reason look in my truck today and realize G13 is in the back of the car which leads me to believe that is what the VW dealership put in. So getting to my question, will G13 and G12 mixing hurt anything because I just mixed 2 gallons of G12 with distilled water and apparently G13 is in the car now after the flush?
