Shires Garage has a team of experienced Mercedes technicians on hand to maintain and fix Mercedes vehicles. We are a local, family-owned workshop that serves the local area. Contact us today if you need diagnosis, repairs, or maintenance in your Mercedes.

Most Common Issues in Mercedes Vehicles

Mercedes cars are known to have a high attention to detail, balanced handling, and extreme comfort. They do experience faults from time to time though, and some are common across most models. To keep your vehicle in optimal condition and lasting for years to come, read this handy guide for common faults, written by our Mercedes experts.

When Mercedes owners enter our workshop, these are the common issues we see in their vehicles:

  • AdBlue Issues – AdBlue is essential for cleaning harmful substances from your Mercedes. Problems with the AdBlue system could affect your car’s chances of passing the MOT emissions test or, in severe cases, prevent it from starting. Contact the experts at Shires Garage, your reliable Mercedes specialists in Langport to address this concern.
  • Electrical Issues – Wiring problems in your Mercedes can lead to various issues. Common problems include throttle body and DPF sensor wiring issues, which may result in a noticeable burning plastic smell or electrical issues. It’s not advisable to ignore these signs. Instead, seek immediate attention from our Mercedes specialists at Shires Garage to assess and fix potential wiring issues.
  • Coolant Problems – Water pumps play a crucial role in circulating coolant in your Mercedes engine. A leak in this system can cause visible puddles under your vehicle or, in more serious cases, make your Mercedes overheat. To prevent this issue from getting worse, contact Shires Garage, your Langport-based Mercedes specialist.
  • Challenges with High-Pressure Fuel Injectors – High-Pressure Fuel Injectors play a vital role in delivering fuel to your Mercedes engine. Sometimes, these injectors may experience problems like blowing or leaking, causing carbon build-up in the engine. If you observe a decline in your vehicle’s performance, it’s wise to contact our dedicated team at Shires Garage today.

How to Identify Common Mercedes Faults

To help avoid expensive repairs in the future, it’s vital that you know the most common issues in your Mercedes.

  • Warning Lights: Pay attention to the warning lights on your Mercedes dashboard. These lights can indicate problems like AdBlue malfunctions, engine irregularities, brake issues, or electrical problems.
  • Unusual Sounds: If your Mercedes makes strange noises like squeals, grinds, or knocks, it could mean there’s a mechanical or electrical problem that needs immediate attention.
  • Abnormal Vibrations: Be aware of any unusual vibrations while driving, as they might signal issues with the wheels, suspension, drivetrain, or even the electrical system.
  • Performance Challenges: Keep in mind that Mercedes vehicles may face performance issues due to various reasons, including engine problems, transmission issues, fuel system troubles, or electrical challenges.
  • Fluid Seepage: Check for leaks under your Mercedes to see if there are any faults in the engine, transmission, or other related components.

Does my Mercedes Warranty Cover Common Faults?
