Everything You Need to Know Before your MOT
GET CLEAR ANSWERS ON MOT REQUIREMENTS, EMISSIONS FAILURES, DPF BLOCKAGES, EGR/ADBLUE FAULTS & ENGINE PERFORMANCE ISSUES.
WE ENSURE YOUR VEHICLE MEETS LEGAL TEST STANDARDS WHILE IMPROVING RELIABILITY, PERFORMANCE & EMISSIONS.
At CK Autos – Carey & Kyprianou, we help you get your vehicle MOT-ready by finding and fixing the issues that most commonly cause failures. From dashboard warning lights and emission faults to DPF blockages, EGR problems and AdBlue errors, we diagnose the root cause and give you clear options before you book your test.
Our technicians use dealer-level diagnostics and professional DPF cleaning equipment to restore performance, reduce smoke, and bring emissions back within legal limits. Whether your car has already failed an MOT on emissions, or you just want peace of mind before you go to the test centre, we’ll make sure your vehicle is in the best condition possible.
We support cars, vans, taxis and light commercials across Hertfordshire, North London and the surrounding areas, offering honest advice, clear pricing and work that’s carried out to a high standard.
Pre-MOT Diagnostics
Full scan of fault codes, live data and emissions-related systems (DPF, EGR, AdBlue/NOx) so you know exactly what needs attention before the MOT test.
Emissions & DPF Solutions
On-car chemical cleaning and off-car deep DPF cleaning to restore flow, reduce smoke and help your vehicle meet MOT emissions standards legally and safely.
Post-Failure Support
If your vehicle has already failed on emissions, we diagnose the cause, carry out the required work and provide evidence so you can return for a successful retest.
