HI I HAVE AN AUDI A4 2.4 SE V6 AUTOMATIC , I HAVE A PROBLEM WITH THE GEAR OIL AND WATER MIXING CAUSING THE CAR TO OVERHEAT AND FORCE WATER OUT FROM THE ENGINE, ALSO CAUSE THE CAR IS LOSING GEAR OIL WITH THE WATER IT IS ALSO AFFECTING THE DRIVE. I HAVE TO PUT MY FOOT HARD ON THE GAS TO GET A LITTLE DRIVE. CAN ANYONE HELP PLEASE.

 

i hope im reading this wrong why the hell is there water in your gear oil. flash out the whole system and refill it. not sure how much itll cost int he europe but at the local service station here in the states its like 100usd for system purge and refill.

 

Water and tansmission fluid could be mixing in the radiator/transmission oil cooler. If there is a crack between the two tanks/tubes, then they will mix. The Transmission runs higher pressures than the cooling system, therefore it overpressurizes the cooling system, and allows trans oil to mix with coolant. Have a competent shop disconect the trans cooler lines and then pressurize the cooling system, fluid should start pouring out of the trans cooler. You will need to get your cooling system flushed AND your transmision flushed once the radiator is replaced.
