Retrofitting is one of the smartest ways to upgrade your Mercedes without buying a new model – but it’s also one of the most misunderstood. From myths about warranty issues to confusion over part quality, there’s no shortage of misinformation out there.
Let’s set the record straight.
We’ve spent decades helping Mercedes owners enhance their vehicles with factory-standard upgrades. Let’s break down some of the most common misconceptions about retrofitting and explain why they don’t hold up.
Myth 1: ‘Retrofitting Will Void My Warranty’
This is by far the most common concern – and it’s not entirely unfounded. But here’s the nuance: retrofitting won’t automatically void your Mercedes warranty, especially if it’s done correctly with OEM or equivalent parts.
The Truth:
If an issue arises that’s unrelated to the retrofit (say, an engine fault), your warranty is still valid. However, if the retrofit directly causes a problem, and it was installed improperly or used substandard parts, the warranty may not cover that specific issue.
What matters is how it’s done – and by whom. We only use genuine Mercedes or OEM-grade parts and install them using approved methods. That means your car’s integrity remains intact, and your warranty stays protected.
Myth 2: ‘Aftermarket Means Cheap and Unreliable’
Not all aftermarket components are created equal. While some off-brand eBay kits might raise a few eyebrows (and for good reason), professional retrofitters don’t use cut corners.
The Truth:
There’s a big difference between ‘aftermarket’ and ‘low quality’. Many retrofits use OEM-equivalent parts – these are manufactured to the same specifications as Mercedes originals but don’t carry the Mercedes badge. They’re reliable, tested, and fully compatible when installed correctly.
We always recommend the right part for the right car. Whether it’s a CarPlay retrofit or ambient lighting installation, we only use components that meet our exacting standards – and yours.
Myth 3: ‘It Won’t Look Factory-Fitted’
Worried about clunky wires, poorly cut panels, or clashing components? That’s not what a professional retrofit looks like.
The Truth:
A properly retrofitted feature is virtually indistinguishable from a factory-fitted one. That’s because it’s installed using the same methods, mounts, and connectors – right down to the hidden wiring and coding updates.
We specialise in seamless integration. Every detail – from fascia finishes to steering wheel controls – is taken into account. Our work is designed to be invisible in the best way possible.
Myth 4: ‘Retrofitting Is Only for Older Cars’
Some people assume retrofitting is only useful for older models missing newer tech. But that’s not the full picture.
The Truth:
Even newer Mercedes vehicles can benefit from retrofitting. Not all features come standard, and some are restricted by trim level or market specification. You might have a 2022 model that didn’t come with cruise control, folding mirrors, or a reversing camera – all of which can be added post-purchase without compromising quality.
Myth 5: ‘You Can Only Retrofit at a Mercedes Dealership’
While dealerships do offer retrofit packages, they’re not your only option – and certainly not always the most cost-effective one.
The Truth:
Braybrooks provides dealership-level quality without the dealership price tag. Our technicians are Mercedes specialists, and our installations match or exceed OEM standards. In some cases, we also offer customisation options that go beyond what dealers are willing to install.
You don’t need to pay a premium for peace of mind. You just need the right partner.
Myth 6: ‘Retrofitting Is Too Complicated or Risky’
There’s a belief that upgrading a modern vehicle’s tech is risky – full of coding issues, warning lights, or electrical gremlins.
The Truth:
Retrofitting can be risky… if you cut corners. But when done by experienced professionals using the right tools, it’s safe, seamless, and stress-free.
We use official diagnostic systems like Xentry and STAR to ensure your vehicle’s electronics are correctly coded and updated after every installation. That means no error messages, no lost functions – just smooth performance.
Myth 7: ‘Retrofitting Won’t Add Value to My Car’
Some drivers worry that adding features post-purchase won’t increase the value of their Mercedes. But in many cases, it actually does.
The Truth:
Features like Apple CarPlay, heated seats, and towbars are often high on buyers’ wish lists. A professionally retrofitted system – especially when OEM-standard – can improve resale appeal and help you stand out in a competitive market.
According to YouGov, 57% of Brits would choose to add parking sensors over any other optional extra. That’s a strong signal that retrofitted features are seen as valuable – not just to you, but to future buyers too.
Don’t Let the Myths Hold You Back
Retrofitting isn’t about cutting corners or compromising your Mercedes. It’s about enhancing what’s already there – responsibly, professionally, and with factory-level precision.
Braybrooks has spent over 40 years building a reputation for OEM-quality retrofits. Whether you drive a W205, X253, W212, or S-Class, we make upgrading your car simple, reliable, and rewarding.
