JEMKA Limited was founded with a single mission: keep every Mercedes performing exactly the way Stuttgart intended — without forcing owners to pay main-dealer rates for the privilege. We are an independent Mercedes-Benz specialist based on Whitby Road in Slough, serving drivers across Berkshire, Buckinghamshire and West London.
Our workshop runs the same Mercedes Xentry® diagnostic platform used by official dealerships, fitted with current software updates and genuine parts pipelines. The result is dealership-equivalent work, on the dot, at independent pricing — backed by transparent quotes and a service stamp that protects your manufacturer warranty under EU Block Exemption rules.
We look after everything Mercedes builds, from classic saloons and SUVs to AMG performance models, EQ electric vehicles and plug-in hybrids.
Every service backed by Xentry® diagnostics, genuine parts and a written warranty. No surprises, no upsells — only what your Mercedes actually needs.

Modern Mercedes models run dozens of interlinked ECUs. A warning light is rarely just one fault — it is a clue. We trace the root cause across the entire network, then explain what we found and what it actually costs to fix.
From classic W124s through to current EQ and AMG models, petrol, diesel, hybrid and full electric.
Engine, gearbox, ABS/ESP, airbags, infotainment, AIRMATIC, distronic, climate — every module scanned, logged and coded.
Printed or digital report of every code, what it means and how urgent it is — never just a list of acronyms.
Drop in for a fault scan — most diagnostics are completed within 45–90 minutes.
Every Mercedes that comes through our doors follows the same disciplined process — so you always know what is happening to your car, and why.
