Diagnostics
We believe regular servicing shouldn’t cost a fortune. Customers enjoy superb value compared to main dealer prices, without compromising on quality or care.

Diagnostics

At Newtons Mercedes Specialists in Littlehampton, we combine advanced Mercedes-Benz diagnostic equipment with decades of hands-on expertise to identify faults efficiently and fix them correctly — first time.

Modern Mercedes-Benz vehicles are among the most technically advanced on the road, equipped with a complex network of sensors, processors, and control units that constantly monitor performance, emissions, and safety. When one of these systems detects a fault, it records a diagnostic code that can be read by specialist equipment — but understanding what that code really means requires human experience and mechanical insight.

The Human Touch Behind the Technology

While diagnostic equipment is vital, it’s only as effective as the person interpreting it. Our team brings years of dealership-level experience to every vehicle we assess. This blend of expertise and technology means we can diagnose faults faster and more accurately than many general garages — saving you both time and money.

We know that today’s Mercedes models are built with sophisticated microchips, electronic modules, and computer-controlled systems. From hybrid drivetrains and sensor arrays to advanced driver-assistance systems, our familiarity with these components ensures that no issue is too complex for us to handle.

Amazing service, professional, quick, and reasonably priced! Can't sing their praises enough, Karen on reception is super friendly and they helped fix the air suspension which had collapsed on my E Class.

Very good independent Mercedes specialists. Been a customer for 8 years. Very reasonable prices compared to main dealer and a courtesy car, which is a bonus. I would not go anywhere else.

Popped in with a boot problem, no pre-booking. Explained the problems with my boot mechanisms and rear camera issues. Darren said straight away that it sounds like an electrical fault with some wires as all the problems are in the same area. No mention that any expensive parts are needed. As I’m not local to here, he looked at my car straight away and found the faults and asked if I was ok to wait while he fixed it; and the.ln ran full diagnostics for me. Couldn’t ask for faster, better or more honest service. Karen on reception was very pleasant to deal with while I waited too. Would 100% recommend.

Brilliant experience with these guys. Sorted out my car nice and quick, at a good price. When I had to go back to check another issue they were extremely helpful and also provided a courtesy vehicle. Daniel at the front desk is friendly and professional, providing clear communication the whole time. Would absolutely recommend and will use again if need be!
