Problem with flashing ABS warning light and defective brake light on Mercedes Vito 2018
(Translated from German)
Summary of the thread
A Mercedes Vito 2018 owner is experiencing a flashing ABS warning light and a non-functional brake light. The suspected cause is a faulty brake light switch, but there's uncertainty. A similar issue in a Mercedes Sprinter was resolved by replacing a faulty control unit, which could also be the cause here. The recommendation is to visit a garage for a diagnosis and consider using used parts to reduce potential repair costs.

Hey, thanks for your quick reply! I already have 134531 km down and my last service was a few months ago. Honestly don't know when the ECU was last changed. Really hope it's not that, sounds like an expensive repair....

Hey, no problem, that's what we're here for! Well, it sounds like you're on the road quite a bit. So, given your mileage and the age of your Vito, it could well be the control unit. But don't worry, it could just be a sensor. I would recommend you go to your garage as soon as possible and have it checked - before it gets worse. And if it is the control unit, look for used parts. I got mine replaced for 750 euros back then. So the repair costs might even be lower. Please keep us posted on how it turns out. Good luck!

Hey thanks, that's really helpful! I will definitely go to the garage and get it checked out. And I'll look around for used parts, hopefully I can bring the cost down a bit that way. I'll let you know as soon as I know more. Thanks again and see you then!

Hey, I know your problem. I had something similar with my Mercedes Sprinter (built in 2016, also petrol engine). I'm not a master mechanic, but I've had a few experiences with cars. I then went to my garage and they found out that it was the control unit that was faulty. It cost me 1000 euros to replace it at the time. Could be the same for you. How many kilometers have you driven and when was the last time the control unit was replaced? With a little more information, we might be able to narrow down your problem better.
