A Slough workshop that treats every Mercedes like its own.
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.
Workshop services
Mercedes-Benz care, end to end.
Every service backed by Xentry® diagnostics, genuine parts and a written warranty. No surprises, no upsells — only what your Mercedes actually needs.

Xentry® Diagnostics
Same platform Mercedes dealers use — kept current.
Diagnostics & coding
Catch the fault before it costs you.
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.
Every Mercedes model covered
From classic W124s through to current EQ and AMG models, petrol, diesel, hybrid and full electric.
Full Xentry® coverage
Engine, gearbox, ABS/ESP, airbags, infotainment, AIRMATIC, distronic, climate — every module scanned, logged and coded.
Plain-English fault report
Printed or digital report of every code, what it means and how urgent it is — never just a list of acronyms.
No appointment required
Drop in for a fault scan — most diagnostics are completed within 45–90 minutes.

"Took my C63 in after the main dealer quoted me a fortune for what turned out to be a coding fix. JEMKA found it in an hour, charged a fraction. Honest workshop — I will not go anywhere else."
"Annual service and MOT on my GLE done same day, ready before I needed to leave for work. Stamped book, full digital report, no upsell. Professional from start to finish."
"I run an EQS and was nervous about going independent. Their EV knowledge is excellent — HV battery diagnostics, charging system check, software update, all done properly. Dealer-level work."
