Re: Audi / VW engine coolant the same?

Craig;

    It sounds like you have a definite problem with your coolant. Make sure
you flush the cooling system well and use only phosphate-free coolant. That
nasty brown colour is probably caused by rust resulting from corrosion in
the engine passages. The coolant should last for years without changing
colour or becoming cloudy.
