Exhausts & Batteries

Frequently Asked Questions

An exhaust service involves inspecting the whole system for:

Leaks or corrosion
Damaged clamps
Worn gaskets
Issues with the catalytic converter or DPF

Technicians also check for emissions faults, such as problems with lambda or NOx sensors. If anything needs replacing, you’ll be advised before work begins. You can find details about our repair process on the Exhausts & Batteries page.

Common signs include:

  • Slow starting
  • Dim interior lights
  • Electrical glitches
  • Sulphated battery struggling in colder weather

Older batteries also lose charge faster and may fail without warning. If you’re unsure, a quick health check will confirm whether the battery or charging system is at fault. You can arrange a free test via our Contact page.

Typical symptoms include:

A hissing or tapping noise under the car
Stronger exhaust smells
Dashboard emissions warnings
Reduced fuel efficiency

Vibrations through the pedals or steering wheel can also indicate a leak. Exhaust leaks worsen over time, so early inspection is recommended. You can learn more about what we repair on our Services page.

Most car batteries last 3-5 years. However, their lifespan shortens with frequent short trips, hot summers, cold winters, or long periods of disuse. As a battery ages, chemical reactions slow and cranking power drops, especially in winter. Regular testing helps identify early failure. You can check which vehicles we work on via our Vehicles We Service page.

Yes, leaks or worn components can reduce:

Engine efficiency
Cause poor fuel economy
Trigger emissions faults that affect how the engine manages air and fuel

A damaged catalytic converter or blocked DPF can also restrict power. If performance has dropped suddenly, an inspection is worthwhile. You can read customer experiences on our Testimonials page.

Yes, a completely flat battery can sometimes be revived with a smart charger. However, heavily sulphated batteries often can’t recover, especially if they’ve been left discharged for days or weeks. Revival also depends on the battery’s age and internal condition. A quick diagnostic can confirm whether it’s chargeable or needs to be replaced. You can arrange testing on our Exhausts & Batteries service page.

Yes, an exhaust leak can allow oxygen into the system, affecting sensor readings and forcing the engine to run inefficiently. This may cause poor fuel economy, higher emissions and long-term stress on components such as the catalytic converter. Over time, unresolved leaks can lead to bigger repairs. For an inspection, visit our main Services page.

Common causes include:

Interior lights
Boot lights
Dash cams
Alarms
Faulty alternators
Parasitic electrical faults

Cold weather also increases self-discharge, while older batteries lose stored energy more quickly. If your battery keeps going flat overnight, a diagnostic check is essential. You can book one through our Contact page.

Most exhaust systems benefit from an inspection once a year, or sooner if you hear unusual noises, smell fumes, or notice drops in fuel efficiency. Short journeys can cause moisture build-up, which increases corrosion. Meanwhile, potholes can damage brackets or pipework. Regular checks help prevent larger repairs. You can see what vehicles we support on our Vehicles We Service page.

Most battery replacements take 10–20 minutes, depending on:

Access
Mounting brackets
Whether a diagnostic reset is required

Some modern vehicles need coding to ensure the charging system recognises the new battery. A quick test beforehand confirms you’re replacing the correct component. For fitting options, visit our Exhausts & Batteries page.
