The latest GW reader challenge from Euro Academy’s technical helpline concerns a 2012 Volkswagen Passat 2.0 TDI which would start, run for 5 seconds and then cut out.
The repairer performed a fault code scan, but no error codes were revealed.
A live data read of the fuel pressures was also completed but the results clean.
After double-checking that there were no issues with the fuel filter connections, the repairer called the helpline.
The advisor confirmed that the fuel pressure figures were correct according to the information provided by the OEM.
However, the car was still cutting out after five seconds.
What was the solution to the problem? Think you’ve got it? We will publish the solution and give you another technical challenge next month on GW.
Solution: Megane Scenic shows 40 fault codes
GW recently published a problem job on 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 first piece of advice from the Euro Academy helpline was to check the state of the battery and to make sure it was charging correctly.
The battery was fine, so the helpline advisor thought it could be a voltage issue.
The repairer was sent a checking procedure for the Volkswagen Smart charge cycle.
After performing the check, the repairer confirmed that the charge cycle was not operating to manufacturer specifications.
The helpline advised the repairer to remove the alternator and to test it.
The repairer noticed that it had been recently replaced with a poor-quality unit.
After replacing the alternator with an OEM equivalent all codes cleared automatically, and the car was returned to a happy customer.
