Audi S4 and S5 sales halted as new engine software is tested
Performance pair are among several Audis that could receive adjustments to CO2 and economy figures
The two performance models are among several Audis due to get new software. A source told Autocar that the resulting effects would have to be tested by German regulators before more cars can be sold.
“Audi has decided on a stricter interpretation of tolerances of the regulations for measuring CO2 emissions applicable in the EU,” said an Audi spokesperson. “This may lead to adjusted CO2 figures for some Audi models.”
The spokesperson said the changes to the S4 (above) and S5 were being implemented to improve “comfort and spontaneity” and “may lead to a moderate increase in fuel consumption”.
Our source said changes are also being applied to the A4 2.0 TFSI, but Audi has refrained from commenting on this. No timescale has been set for the reopening of order books for the S4 and S5.
