Problem job: Megane Scenic shows 40 fault codes across various control units
Euro Academy’s technical helpline challenges you to solve a problem recently encountered with a Renault Megane Scenic.

The latest GW reader challenge from Euro Academy’s technical helpline concerns a 2011 Renault Megane Scenic, which was experiencing in excess of 40 fault codes, spread across various control units.

Although the fault codes were temporarily cleared, they quickly returned.

It was not possible to confirm each fault individually as there were no apparent symptoms on display, as well as a very high number of faults to check.

The repairer called the technical helpline – do you know the solution to this problem job? Find the answer here on GW later this month.

Solution: Nissan Qashqai’s ABS

GW recently published an issue with the DPF on a Nissan Qashqai.

Two codes were found, one relating to DPF pressure and the other to the ABS system.

The repairer focused on the DPF issue and after replacing the differential pressure sensor and the DPF itself, they were still unable to get rid of the fault code.

The master technician advised the repairer to test the exhaust pressure sensor and to check two specific hoses for blockages.

They also provided a diagram to assist with finding the faulty sensor.

Having replaced this sensor and cleaned the pipes all codes were cleared, and the car was returned to the customer.
