Hi Mike - We're having the same issue on EQC. Was MB able to sort it out? Are you able to clear the fault anyhow?
Alex, the MB dealer tried to resolve the issue, however, two days after I collected the car the same malfunction light came on and then again a week later the same thing happened yet again. I’m monitoring the malfunctions and logging them as and when they occur. So In short, it appears that they have not sorted the root cause. Each time the malfunction lights come on the dashboard they have then disappeared when I have pressed the ignition button. Charging does not seem to be affected nor does the performance of the car. But as you can imagine my worry is that the battery will malfunction and that I’ll be stranded. I’ll be calling up the MB dealer next week to report my observations and requesting a replacement car until they have successfully identified and resolved the root cause. One of the big issues is the MB dealers reluctance to provide a replacement car. I’ve been advised that you need to just drive in, declare it’s a breakdown and insist on them providing a replacement car. I just don’t have the time to play all these “games”. Despite being a loyal Mercedes customer for more than 20 years, I’m not going to be sticking with a Merc after multiple incidents with this EQC. Parktronic doesn’t function, air conditioning was not working for months, etc, etc. I’ve had enough! For a car costing upwards of £70,000 it’s just not acceptable and is verging on mis-selling. I attach a copy of the tests and updates which the technicians claim to have done but as I say the problem persists. Please share with me your experience and, hopefully, solution as they unfold. Michael
