Faults stored in the ECU
Our customer saw that her Mercedes-Benz CLS 320 was under-powered. She brought the car to our Ipswich workshop. She explained that she had visited two other Mercedes Benz specialists, and that she was beginning to believe that she would never be able to get it in working order. So, she was standing in our workshop trying to find the problem with her Mercedes CLS.
The local independent Mercedes expert, the team welcomed the Mercedes and began diagnosing it immediately using main dealer equipment (Mercedes Star & Mercedes Xentry).
Diagnose the Faults
The Mercedes specialists began by accessing the vehicle’s supply data, which revealed several defects.
- P2350 – Inlet port shutoff engine short to ground
- P2376 – Throttle valve actuator voltage low
- P2514 – Vent line heater short-to-ground
- P2526 – Charge pressure positioner short-to-ground
- P2527 – EGR positioner short for ground
- P2626 – Too high soot content in DPF
There are quite a few errors there!
GEL Automotive is known for providing five-star customer service. Our technicians understood that we needed to quickly identify the problem and fix it.
Once you have received the fault codes, it was now time to determine why and how they occurred.
It takes a lot of skill and experience to narrow down the problem.
Solution to the problem
We first checked to see if there were any faults. Then we checked the fuses. Our technicians quickly identified the failures by using the Mercedes wiring diagram. Our technicians replaced the fuse and checked the codes for any updates.
Some of the faults were fixed, but others remained. We did discover signs of damage to the impeller, and oil leaking onto an actuator. This problem was obvious and we investigated further. We determined that the turbocharger needed to be replaced.
We repaired the swirl flap actuator and the turbocharger and replaced it with a new one. Our Mercedes specialists were able to repair the CLS 320 with all of these parts.
We chose to repair the swirl flaps, and the manifold of the Mercedes intake manifold instead. This saved time and money for the customer. She was able to trust that the garage she had chosen was GEL Automotive in Ipswich.
