A customer’s journey of discovering Mercedes-Benz error codes!

As an owner of a Mercedes-Benz motor, you may be used to encountering various issues. 

Don’t get us wrong; there’s a reason why Mercedes-Benz are one of the most recognisable car brands on the planet, and to their credit, they create sleek and easy on the eye vehicles year after year consequently.

Remember, beauty is only skin deep, so when it comes to your Mercedes, be prepared to encounter issues under the bonnet, just as much as you could with any other car brand. 

A simple relaxing cruise around the countryside can suddenly turn into a nightmare situation and a costly one at that. It is possible that the issues encountered were caused whilst out on the road; however, it is also possible that the issues could have been there for a while and you just hadn’t realised. 

Unfortunately, this situation occurs far more often than it should do when it comes to many car brands, including Mercedes-Benz. 

After some time with his Mercedes-Benz CLS 320, our customer, Mr Cope, had noticed an issue. You would have thought after consulting several garages that the issue would have been fixed, right? Well, yes, you would expect so. After visiting two separate garages without success, Mr Cope made the wise decision to bring his Mercedes to us.

Diagnosing the problem

As Mercedes experts, our team here at Fitch Autos received the car and ran various tests, finally finding the issues causing pain to Mr Cope and his Mercedes. 

Unfortunately for the customer, the vehicle had several faults. 

What would you do in this situation? 

Sure, you may be concerned, but ultimately you’ll be relieved that your pride and joy is in the hands of our knowledgeable mechanics. It’s always worth reminding yourself that when hearing that your car has a number of issues, that it’s only temporary – you’ll be back on the road in no time when you bring your car to Fitch Autos.

After several cups of tea, biscuits, and a trip to the shop to replenish the empty tea bag jar, we fixed the issues, and Mr Cope was away, driving and loving life! 

Well, not quite that straightforward…

Let’s rewind a little and take a look at the issues that were diagnosed with the vehicle,

The problems that were diagnosed are as follows: 

  • Mercedes Fault Code P2626 – Soot Content of DPF too high
  • Mercedes Fault Code P2530 – Inlet port shutoff motor short to ground
  • Mercedes Fault Code P2527 – EGR positioner short to ground
  • Mercedes Fault Code P2514 – Vent line heater short to ground
  • Mercedes Fault Code P2526 – Charge pressure positioner short to ground
  • Mercedes Fault Code P2376 – Throttle valve actuator – voltage low

It is important to remember that knowing the fault code is simple; the art of diagnosing the issue and fixing it is to take the information and run the appropriate tests to pinpoint the root of the problem.

Let’s fix the problem!

Our technicians wasted no time in consulting the wiring diagram to find the components fused from the same fuse, which were then replaced, rectifying some of the fault codes affecting the vehicle. The remaining fault codes were solved by inspecting the turbocharger and discovered signs of impact to the impeller and oil leaking onto the actuator. 

The customer’s Mercedes-Benz CLS 320 was up the creek but at least we now had a paddle and directions!

After replacing the turbocharger, repairing the swirl flap and replacement rod, the swirl flap actuator and one fuse, the job was almost complete. 

You could actually see the smile slowly rise on Mr Cope’s face; well, you could have if he wasn’t at home waiting patiently as we were working tirelessly to fix the vehicle. But you know, he was definitely smiling; take our word for it. 

Did we stop there? No.

We value our customers

Now, we value our customers at Fitch Autos, and as Mercedes experts, we understand that the cost of such repairs for many fault codes can be an expense that empties your bank account quicker than the 2020 Mercedes AMG GT Coupe goes from 0 to 60. If you’re wondering, it takes just 3.1 seconds! Our knowledge of Mercedes vehicles isn’t a flex; we genuinely are enthusiasts and experts.

Instead of performing an unnecessary total replacement of the intake manifold, we chose to repair the swirl flaps and manifold to save the customer money, time and to provide a service that instructional DVDs on customer service shown at your work induction would be proud of.

Not only did we save the customer money, we provided a quick turnaround on this reasonably complicated job, lost plenty of milk, tea bags and sugar, but the job was completed to exceptionally high standards, which we pride ourselves on.

That is just what we do!
