Scotty - I have a 2016 VW Tiguan, roughly 48,000 miles on it. A few months ago the low antifreeze light came on so I sucked out the remaining antifreeze from the overflow and replaced with new fluid to the max line.
Now it appears I am losing antifreeze, the fluid level is below where I filled it to but not overly noticeable. I do not see any leaks anywhere, engine bay is really clean. Even had it checked underneath and no appearance of a leak.
Any idea on what could be happening or where to look for the leak? I assume a pressure check is what should be done but curious if you know of anything problematic with these Tiguans and losing antifreeze.
Cheers!!!
Try changing the radiator cap and check if that fixes it. Also, since it’s a VW, I would look at the water pump & thermostat assembly very closely as they are notorious for leaking coolant from there.
