Exhaust & Emissions Repairs London & Surrey | 22 MOTORS™
If your car sounds louder than normal, smells of fumes, shows an engine management light, or you’ve failed an MOT emissions test, your exhaust and emissions system needs attention. The exhaust system doesn’t just reduce noise — it manages exhaust flow, supports fuel efficiency, and works with emissions components like the catalytic converter, oxygen sensors and DPF to keep your vehicle compliant.
22 MOTORS™ provides exhaust and emissions repairs in London and Surrey for cars, vans and commercial vehicles. We diagnose properly first, then fix the cause with transparent estimates and repairs designed to last.
Why Choose 22 MOTORS™ for Exhaust & Emissions Repairs in London & Surrey
Exhaust and emissions faults are often misdiagnosed. A rattle might be a heat shield, a “blowing” noise might be a cracked flexi pipe, and an emissions warning light might be caused by a leak before a sensor rather than an expensive catalytic converter. We use evidence-led diagnosis to confirm the root cause, explain your options clearly, and verify the repair so you’re not stuck in a cycle of repeat warnings or repeat MOT failures.
Common Signs You Need Exhaust Repair or Emissions Diagnosis
Book an inspection if you notice a loud blowing exhaust, ticking on acceleration, rattling underneath, fumes smell around the vehicle or inside the cabin, visible smoke, loss of power, poor fuel economy, exhaust hanging low, corrosion holes, engine management light, emissions warnings, DPF messages, or an MOT emissions fail.
If you smell fumes in the cabin, treat it as urgent. Exhaust leaks can be dangerous.

Emissions Diagnostics and Repairs
Modern vehicles rely on sensors and emissions components to keep exhaust gases within legal limits. We diagnose and repair common emissions-related faults including:
Engine management light and emissions warning diagnosis
Lambda/O2 sensor diagnosis and replacement
Catalytic converter efficiency faults and related testing
DPF diagnostics and regeneration pathways where appropriate
Exhaust leaks affecting sensor readings and fuel trims
Smoke test for intake/vacuum leaks linked to emissions behaviour
Investigation of repeated DPF loading and soot production causes
We don’t default to replacing expensive parts. We confirm whether the fault is caused by leaks, sensors, incorrect readings, soot loading, or internal failure before recommending a repair.
Catalytic Converter and DPF Issues Explained
A catalytic converter helps reduce harmful gases and can trigger warning lights if it isn’t operating efficiently. A DPF captures soot and must regenerate under the right conditions. Both systems can be affected by driving patterns, fueling faults, air leaks, and sensor issues. Clearing codes without fixing the cause usually leads to the light returning. Our focus is to repair the underlying issue so the vehicle remains reliable and compliant.
MOT Emissions Support and Failure Repairs
If your vehicle has failed an MOT due to emissions, we can diagnose why and carry out the correct repair pathway to help you pass. This may include fixing exhaust leaks, correcting sensor faults, addressing DPF-related issues, or resolving underlying engine issues that cause excessive emissions. We’ll explain what’s required and why before any work starts.
Why Exhaust & Emissions Repair Costs Vary
Costs depend on the location of the fault, how corroded fixings are, and whether the solution is a small repair or a larger replacement section. Costs can also increase if sensors, catalytic converters or DPF components are involved. We provide clear options so you can choose the right balance between cost and longevity.
