Mercedes CLA45 AMG (2017) — Misfire Mystery Solved
This one came in barely drivable — a serious misfire but no fault codes, no engine light, nothing showing in diagnostics.
After checking the live data, I found the injectors weren’t working correctly even though the ECU showed no errors.
I carried out some tests to confirm the issue, sourced a fresh set of injectors, and got them fitted.
Now the AMG is running smooth again and the customer’s back on the road with a big smile 😎
Just another example of what we do best at Maps and Mods — getting cars running how they should. 💪
