Volkswagen Dieselgate fix under BBC Watchdog investigation

Volkswagen Dieselgate fix

The BBC’s investigation follows an in-depth Autocar report about the implementation of a defeat device fix

The BBC’s Watchdog consumer investigation programme will tonight focus on the spate of problems reported by owners following the fitment of a post-Dieselgate fix to their Volkswagen Group cars. 

The programme is investigating owners’ claims that their cars went into limp-home mode unexpectedly after the fix. Volkswagen has said an “overwhelming majority” of its customers who have had the fix applied to their cars are happy with it.

Autocar has previously tested a car before and after the Dieselgate fix was applied. Although no outright faults were detected, the car gave poorer fuel economy and greater CO2 emissions after the update, despite NOx emissions being halved by the tweak. 

Following the fix, the owner of the car tested by Autocar had been presented with a ‘Certificate of Completion’ that stated the performance, fuel economy, CO2 emissions, torque or noise of the car were all unaffected by the fix. 

Volkswagen has already responded to the BBC’s investigation, which airs this evening at 8pm. VW said: “Implementation of the technical measures does not cause limp-home mode to engage nor does it increase the incidence of limp-home mode occurring. Limp-home mode is a safety feature of our, and many other, vehicles. It is activated as a precaution if a vehicle experiences a fault.”

“Relevant authorities have confirmed that the technical measures have no adverse impact on the mpg figures, the CO2 emissions figures, engine output, maximum torque and noise of the affected vehicles. Nor does the implementation of the technical measures have a negative impact on the durability of the engine or the emission control system.”
