Why Slick Autos
Dealer tools. Independent thinking.
Dealer-Level Tools
We use genuine Mercedes XENTRY, BMW ISTA and Porsche PIWIS diagnostic systems — the same tools main dealers use, without the dealer price tag.
Diagnostic-First Repairs
Every job starts with live data, fault codes and proper fault-finding — not guesswork. We prove the cause before we quote the fix, so you only pay for work your car actually needs.
Service Record Integrity
Mercedes vehicles serviced here receive official dealer-level digital service records, maintaining your vehicle's full service history.
What drivers say
Trusted by enthusiasts
across Berkshire.
“Two other garages had my E-Class in for the same intermittent fault and couldn't pin it down. Slick hooked up XENTRY, walked me through the live data, and had the real cause identified inside an hour. Haven't had the warning light back since.”
“Main dealer quoted me a DPF replacement and basically hinted at a delete. Slick cleaned, regenerated and reprogrammed it properly — car's been running perfectly for months and the MOT sailed through. Saved me thousands.”
“Stage 2 map on my C63 S feels factory-tight. Throttle response is sharper, torque is relentless, and the before/after dyno sheet spoke for itself. Best tuner I've used in the South East.”
