Don’t Just Take Our Word For It
I was researching issues with my 2016 GLE450 Amg Coupe and I stumbled on an article written by YOUCANIC. The article was well-written, detailed, and very informative…. Very helpful with a diagnosis of the problem with my car free of charge, and was able to pinpoint the issue to the rear right suspension.
The dealership wanted $500 (to replace the auxiliary battery) so I called YOUCANIC and was told its an easy fix. Their website gave perfect instructions so I bought the battery for $50 and installed it in thirty (30) minutes (I have no experience). If you have a Mercedes don’t waste your time, just go to YOUCANIC.com
