Ticking noise outside while driving
My 2019 E450 Cab has an annoying tick-tick-tick noise when driving. The speed of the ticking is directly proportional to the speed of the car. It has done this for at least the last nine months.
I looked for any rocks stuck in the tread of the tires and didn’t find any that were protruding. Just had my first Service A yesterday and asked them to take a look at the tires and the wheels while the car was up in the stirrups.
They said the found nothing wrong (go figure) and they gave me a cockamamie “possible explanation” that I’m hearing the advanced fuel injector. That it will make a ticking noise and that the ticking pace matches the speed of the car.
I call BS. I find it hard to believe MB makes a fuel injector that deliberately makes noise outside the car.
But... I figured I’d post here on the 1 in 1,000,000 chance everybody comes back and tells me it’s normal

2021 E450 Cabriolet
Also have ticking on 2021 E450 Cabriolet
Hi all! We also have this issue on our 2021 E450 Cabriolet. The car has a ticking noise that can be heard on both sides of the car that is speed dependent. It is easiest to hear when near a curb or fence that the sound can bounce off of.
MB service looked at it and changed brake rotors but didn't remove the sound. Now they are saying it is a "normal" noise when they test drove another E450 Cabriolet. We asked to to test drive that car but it is unavailable because it is sold.
I can't imagine MB has purposefully created a ticking part on a convertible!

Obviously rhetorical question.
Of course a ticking sound is not normal. Glad that the dealer has acknowledge the sound. Most of the time they deny hearing it.
In any event, depending on how much the sound bothers you and how much time you want to put into it, I would take my car back to the dealer, get a loaner and tell them to call you when they have eliminated the sound.
Failing that a call to your regional MB would be in order.

S213 2020 E450 4Matic CDN Spec 07/19 build
On my S211, every time I had my tires changed, I'd have to warn the shop to be mindful of brake dust shields/guards. Inevitably, after the swapping, there'd be one-per-rotation chirping or other such noise. To fix the issue, they'd just manually grab what I assumed were the guards and give them a shove. That did the trick.
I don't know if this could be an issue on the 213, but mention it just in case.
