I own 2011 a4 quattro Prem+ auto 2Twith about 21,000 and it appears during initial warm up and intermittently, that there is a response lag upon my initial throttle tip in. More notice in regular (vs sport) setting of transmission.

Is this a none issue with the B8?

I have used techron additive to fuel to see if it might be related to fuel. Only use Shell or Chevron prem fuel.

Also, looking at modifying my exhaust this spring to a Stasis or APR. Any recommendation on a dual vs single exhaust system. I plan on taking it autocrossing and enjoying it on long drives, so I need to strike a balance between decibels and performance. Any insight on set up ?

 

Does anyone have a similar problem?

 

There might be a TSB for this..... ECU re-flash maybe. I didn't think it effected 2011's though.

 

It's an a4 designed as an economy car hence why they have s4's and rs4's. it's not a sports car just bc it's an Audi. Get a good tune or if you wanna drive fast (somewhat at least) then just put it in sports mode.

 

Thanks for your responses. Just to be clear, I understand the B8 A4 will not have a throttle response of a car with a light weight flywheel or with gearing designed for acceleration. Instead, I was referring to no response on the initial throttle tip in, which causes abrupt acceleration when moving from a standing still, especially in winter driving. This happens whether car is warmed up or not.

Any thoughts?
