Chris Allen of the Professional Struggler YouTube channel tackles a persistent power steering leak on his Land Rover TD5 and a stubborn intermittent misfire on his Iveco Daily service van.
First, Chris addresses his Land Rover, which failed its MOT due to an inoperable steering system. After using heat and a heavy-duty puller to release the stubborn steering arm, he extracts the failed input shaft seal from the steering box, clearing a bruised internal casting lip before installing a Rimmer Bros replacement seal kit.
Turning to his Iveco Daily, Chris uses a TOPDON ArtiDiag800 BT to scan the ECU after experiencing a recurring misfire. Despite replacing multiple fuel injectors, a persistent open circuit fault code on cylinder two continues to plague the vehicle.
Troubleshooting with fellow YouTuber Ash (Tattoo Tech) reveals the root cause is poor pin tension inside the ECU harness connector. Squeezing the widened female terminals together with a depinning tool restores terminal contact, instantly curing the misfire.
