ππ¨ SEAT ATECA FR TSI β MISFIRE DIAGNOSIS
This Ateca FR came into us with an engine misfire, but this one wasn't quite as straightforward as it first appeared. π
After carrying out a thorough diagnostic investigation, we traced the issue back to a fuel injector with an intermittent electrical fault. ππ§
The intermittent nature of the fault made it much more difficult to pinpoint, as the injector wasn't constantly showing the fault β making proper testing and diagnosis even more important.
Normally, we'd remove the injectors and have them professionally rebuilt & Nano cleaned, but with an electrical malfunction present, cleaning wasn't going to solve the problem.
