A Guide to Common Car Exhaust Problems
A Guide to Common Car Exhaust Problems

Your car’s exhaust system might not be something you think about every day, but it’s a key part of your vehicle. It keeps harmful gases away, controls noise, and helps your engine run better. If something goes wrong, it can lead to poor performance, more fuel use, and even MOT failure.

At Malling Repair Service, we see a lot of drivers around Maidstone come in with exhaust issues they didn’t spot early. This guide will help you learn the signs and what to do if your car's exhaust system needs help.

1. Your Car Sounds Louder Than Usual

If your car suddenly makes more noise or sounds like it’s growling, that could mean a leak in the exhaust system or a broken silencer. This is one of the most common problems we see at our MOT garage in Maidstone.

A damaged exhaust pipe or silencer can affect not only how your car sounds but also how it performs.

2. You’re Using More Fuel

Has your fuel bill gone up lately? It might not be the petrol prices. A leaking exhaust can cause incorrect readings from the oxygen sensor, which makes your engine burn more fuel than it should.

We often spot this issue during a full car service in Maidstone, especially for cars due for maintenance.

3. Strange Smells While Driving

Smelling something odd, like burnt plastic or petrol, is never a good sign. It could mean hot exhaust gases are leaking near the engine. This can be dangerous and needs urgent repair.

Don’t wait — bring your car to Malling Repair Service for a quick check.

4. Poor Engine Power or Vibration

If your car feels weak when going uphill or shakes more than usual, it could be an exhaust problem. A blocked or broken exhaust pipe makes it hard for the engine to “breathe,” and that affects power.

We help many local drivers with this at our MOT test centre in Maidstone, especially when they're preparing for an MOT.

5. Rust and Corrosion

Rain, road salt, and short trips (which don’t let the exhaust system dry properly) can cause rust. Corrosion on your exhaust system is not only a common MOT fail reason, but it can also cause parts to fall off while driving.

At Malling Repair Service, we check for rust and cracks as part of our inspection — and we’re happy to replace rusty exhausts before they become a safety risk.

Why Exhaust Health Matters for Your MOT

Many people don’t realize how much the exhaust system matters during an MOT. It’s tested for:

  • Emissions levels
  • Leaks
  • Rust or broken parts
  • Unusual noise

So if you want to pass your MOT in Maidstone the first time, it’s smart to have your exhaust checked beforehand.
