Hi. I've just join the forum, in the hope someone might be able to help me. I've searched all over the internet, forums, but I can't see to fix my problem. I've got coolant circulation pump error. The water gets to 90C in 4 min, but the air in the car takes around 10 min to be hot. I've changed 4G0820195E, 059115389P, radiator temperature sensor, 059121737AM and the main water pump with the belt(all genuine parts, except for the mechanical water pump with belt). I know the is 4H0121671G (I didn't changed) and I think there is another pump? If yes what pump and where is it? I don't want to change anymore parts and not to solve the problem. Thank you.
