Hi everyone !! I started noticing that my x3 is leaking the coolant !! I took it to the dealer and they said that it’s the upper hose. They’re charging me thousands to replace it but that piece costs usually $130 ! We declined that service and ordered the new hose so we can replace it. So, my husband did replace it but the leak continued!!! What could’ve happened?
Please guide us!
Thanks

Not to be rude, but this is why service centers are a business. They get paid to properly diagnose issues and repair them accordingly. Before opting for DIY you would have been better of spending that $130 on a diagnostics fee at a Indy shop to verify if the dealer was correct. Then you would have had leverage to get a likely cheaper repair cost with the Indy shop.

It’s also possible that you now have a different leak triggered during the replacement work.

As suggested above, have a good independent BMW shop diagnose it, and also have them look for other frequent under hood issues that it might make sense to deal with at the same time.
