I pulled the engine out and put it back into my A3 about 6 months ago. At the time, I went over possible future failures and the water pump intake had some cracks (it had had a front impact) as something had struck it. So I bought a new one and replaced it. I have had a devil of a time sourcing the Xenon lights & all related kit but now have everything back together and doing short test drives.
There have been no water leaks with the front end all back on, but now after idling for a few minutes, as the water temp comes up just past the first 1/4 mark (the mark at a 45 degree angle), there is a 'popping' noise that starts. Had me stumped for a while but I'm now thinking that this is the water pump kicking in and either not mounting properly, or possibly cavitating(?) I just refilled the coolant from the top and stop/started until the coolant level stabilised.
Would appreciate any thoughts. The sound seems to at the front of the engine.
