RJ Automotive & RJ Technologies Ltd Reviews 

I wanted adaptive cruise control retrofitted to my GLC as it was one feature that I missed from my previous car.

RJ Automotive was recommended to me and after doing my research and emailing Raj at RJ Automotive I decided to go ahead and have Distronic Plus retrofitted to my car.

I’m very OCD about who works on my car but after meeting Raj it was clear he knew what he was doing and talking about. All genuine Mercedes parts to, no cheap copies.

He showed me how the adaptive cruise control worked after he’d finished so I knew what i was doing.

He also helped me out and checked to see if there were any updates for my gearbox software, which there wasn’t, but still great that he made the effort.

I’d recommend them to anyone who is thinking about retrofits and coding,

Perfect service!! Very professonal!!

Top experience. Retrofitted Adaptive cruise control on Mercedes + extra codings. RJ Automotive has expert skills !

I bought an A250 and it had the small 7" screens on. I found Raj through a YouTube video and he was able to retrofit the 10" screens and code the AMG displays in 20 minutes. It was easy to tell that he has done this hundreds of times, as the process was seamless. Very pleased with the results. I'd be recommending him to some friends for sure!

Amazing service! Good communication and was able to add race mode and drift mode to my AMG in no time. Definitely recommend them!

I received a retrofit kit in Ireland for a merc screen upgrade, and initially I was sceptical, but everything just came together like magic. The guys at RJAutomotive answered all of my questions via Whatsapp beforehand, connected to my car remotely from London via the retrofit kit, and the end result was even better than I'd expected. I'm still amazed. 100% recommended! Thank you.

Hi very good communication and service I would recommend any one who want to use Raj to coding for car thanks a million

Just got distronic pro retrofit and coded
Buttons was easy enough to fit and the coding took no time for him todo
Got some extra stuff done aswell so well chuffed

I recently purchased an E53 and looked to unlock Race and drift mode, along with coding the AMG Drive units that I had retrofitted. RJ Automotive was able to resolve failed codings done by another person and successfully activate the drive modes and get the drive units working. He is an absolute legend and I would recommend you look no where else for your coding needs.

Had a great experience with RJ Automotive! The coding process was super easy and worked exactly as described on their website. The installer was very professional and took the time to explain everything needed for the coding, which made the whole experience smooth and straightforward.

Everything worked perfectly right away, which was great to see. One small suggestion: it would be really helpful if, after the coding is done, there was a bit more explanation about how to use the new features. Also, since the installer gets to see the car from the diagnostics it would be awesome if they could suggest additional useful coding options based on what’s already installed.

Overall, really satisfied and would definitely recommend RJ Automotive to anyone looking for quality coding services!

I had adaptive cruise control (DISTRONIC Pro) retrofitted on my Mercedes EQC by RJ Auto, and I’m absolutely thrilled with the results! The team at RJ Auto handled the entire fitting process with incredible professionalism and expertise. They seamlessly upgraded the steering wheel controls on my Sport trim EQC, integrating genuine Mercedes-Benz buttons tailored to my vehicle’s VIN. The installation was flawless, and the new controls work perfectly, making long drives effortless and smooth with the added adaptive cruise functionality. The service was quick, efficient, and carried out at their NW London location with top-notch attention to detail. My EQC’s standard steering wheel now feels like a premium upgrade, and I couldn’t be happier. Highly recommend RJ Auto for anyone looking to enhance their Mercedes with a professional retrofit!

Unlocked some important features on my 2021 GLS which the car should have but was disabled due to UN R79. Both features work really well now as they should have been on the vehicle by default due to the extras already equipped on it. Thanks for sorting this and makes the vehicle a lot better to drive everyday.

After researching both main dealerships and retrofit specialists, I chose RJ Automotive to upgrade my Mercedes A-Class with Distronic (Adaptive) Cruise Control—and they truly exceeded expectations.

They sourced OEM switches from Germany, ensuring a perfect match, and carried out a meticulous in person installation.

Raj’s expertise shone through at every step, from precise coding to seamless system integration. The test drive confirmed the upgrade’s flawless performance—driving is now a joy.

Highly recommended for precision and quality!

Bought 2020 GLC and was quite surprised that it didn’t came with adaptive cruise controls. Googled Raj and he transformed my car with no time. Best experience ever. Professional approach and original parts made My GLC even better. Thanks.

Great service from my initial enquiry Raj was really helpful. Retrofit kit turned up really quick, had all the parts I needed to fit them even small screws I needed. Instructions supplied where really clear. Then the coding afterwards took just a few minutes with Raj connecting to my laptop remotely via anydesk. Great service would highly recommend thank you 🙏🏻

They sent me the obd module and clear instructions to the US in 2 days. Contacted me and coded my 2020 amg gt53 spoiler delete. Spoiler light on dash gone and speed limiter of 90 mph gone. Very professional and stress free transaction!

Got some workdone for my van and got my new key very conveniently,at very reasonable price.He is very knowledgeable and done my spare key very easily and quickly when everyone else said that we can't do it.Thanks

This is the best experience i have ever had, with any company - ever!
The communication is excellent.
The step by step is one point.
Their knowledge is through the roof.
And level of helpfulness and kindness is just mental.

I bought Distronic Pro retrofit for GLC63s.

Before i even purchased, they were extremely service minded - helping, sending calming guides, etc.

I got the package (from UK to Denmark) in just 7 days with normal shipping.

I decided to install it at night/afternoon - and i ran in to a self-caused bump (not installing a connector right) - and i texted RJA at 9PM - 15 seconds after, the solution was sent to me - and they even helped through out the night on whatsapp - no extra charge.

Remote coding went excellent and they are absolute machines when it comes to this stuff. If something is wrong they tell you exactly how to fix it most efficiently.

I have never had such an experience before, and i will be using them for everything in the future.
Pretty sure they can help with pretty much everything or has some kind of solution.

Thanks a lot RJ for giving me such an experience - and a great OEM product.

Wow..

William Tougaard. Denmark.

No issues, fast and quick help.

Excellent service and deep understanding. Even I was breaking the USB cable - it did not affect the service, we were able to schedule the next session really fast. Better service what I was expecting! I got an upgrade to my AMG, CPC and race mode activation.
