At the moment, Audi has stopped taking orders for the new S4 and S5, due to engine software changes for the EU. Apparently, Audi has to work on new engine management software, which will bring stricter emissions tolerances to the Audi S4 and S5, so as to better meet future regulations from the EU.
“Audi has decided on a stricter interpretation of tolerances of the regulations for measuring CO2 emissions applicable in the EU,” an Audi spokesperson recently told Autocar. “This may lead to adjusted CO2 figures for some Audi models.”
These new software changes have to be tested by German regulators before anymore Audi S4 or S5 models can be sold. While these new changes will insure the S4 and S5 meet future emissions regulations, the same Audi spokesperson said that they “may lead to a moderate increase in fuel consumption”.
There’s no time-frame as to how long sales will be halted for, so if you’re looking to buy an Audi S4 or S5, you may have to wait longer than you’d hoped. We have no official word as to whether or not these changes will be made to North American models, but it seemed as if Audi has been focusing on EU emissions. More as we have it.
