Mercedes Faulty Mechatronics Unit
Imagine buying a new Mercedes to find it has a serious problem only a couple of days later.
Stuff of nightmares, right?
Unfortunately, that’s what happened to Mr E. He’d recently bought a Mercedes A-Class, but discovered it had a jerky and prolonged gear change. It’s the last thing you’d want from your new car.
Not only does it give you a poorer driving experience, but it makes your vehicle unsafe to drive.
Luckily, Mr E brought his A Class to our Mercedes specialists at Shires Garage to solve his vehicle’s faults.
What we found
During the initial inspection, our Mercedes experts used their decades of experience alongside the Mercedes manufacturer information to find the cause of the A Class’s jerkiness.
As your local Mercedes specialist, we use the same technical information as the main Mercedes dealerships. You get dealership servicing for better value; what more could you want?
Our Mercedes experts had a suspicion of what was causing the vehicle’s issues but wanted to cover all bases before they proceeded.
Diagnosing the problem
During an extensive road test of the A-Class, our experts confirmed the vehicle’s jerky gear changes. It was a far cry from the smooth drive you’d expect from a Mercedes.
Our diagnostic tests scanned the Mercedes for fault codes and found the following:
- 056200 -The power supply of circuit 87 has undervoltage.
- 051300 – The start enable was not issued.
Now, unless you’re a mechanic, these codes won’t mean much to you. But to our Mercedes specialists at Shires Garage, it points them in the right direction.
One of the codes suggested a power issue with the gearbox, which could be causing the vehicle’s problems.
Our experts referred to the Mercedes wiring diagram and technical information to fully test the power, grounding, and network of the vehicle’s gearbox. All of the results came back fine.
At Shires Garage, our Mercedes specialists use a 15-step diagnostic process to solve any problems. You get a quality first-time fix, saving you time, stress, and money on costly repeat repairs.
Our 15-step diagnostic process digs deep into your car, finding any faults before they develop.
Logically testing the wiring to get a 100% confirmed conclusion is something that other garages may not have done. We’re clinical in all we do and don’t deal with “guesswork”. It’s why we use the 15-step diagnostic process.
As the vehicle’s gearbox passed all the tests, it pointed to an internal fault with the transmission mechatronics unit.
Wondering what the transmission mechatronics unit is? It’s a mechanical system controlled by electronics to help your vehicle change gears effectively.
No wonder Mr E’s A Class wasn’t driving as it should. The mechatronics unit is a crucial part of the vehicle and needs replacing before the problem worsens.
Fixing the Mercedes
Now our Mercedes specialists knew the cause of the problem; we called Mr E to discuss our findings and what he’d like us to do next.
At Shires Garage, you’re in complete control from the moment you enter our doors. We only start fixing your vehicle once you’ve agreed to the work.
Mr E immediately agreed to our recommendations, and our Mercedes experts began sourcing a new mechatronics unit.
As your local Mercedes specialists, we only use genuine Mercedes or high-quality parts during all repairs, maintenance and servicing. Your vehicle always gets the quality it needs to run like new.
Once our Mercedes technicians had sourced a new Mercedes mechatronics unit, it was replaced and reprogrammed to ensure it worked optimally.
Reprogramming is complex, but our Mercedes specialists have decades of experience and the technical knowledge to tackle any issues.
After completing the work, we thoroughly tested the A-Class to ensure it was in top working condition. And do you know what… It drove smoother than ever.
Mr E was pleased to have his Mercedes A-Class working like new. And he was even happier as he’d saved money compared to the main Mercedes dealership. Plus, he was kept in the know throughout the process, which isn’t always the case with some garages.
Our Mercedes experts were pleased to hand Mr E his keys, and he drove away confidently, knowing his vehicle was roadworthy again.
