2001 A 8 Hesitation
--------------------------------------------------------------------------------
Since new my Q has had hesitation from a near stop condition. Almost stop at a stop sign and hit the gas and for a second nothing. Now getting much worse. Dealer says normal. I know he lies to me. Anyone have a fix? It is a 2001

What engine please? 2.8, 3.7 or 4.2. Is it a flat spot, i.e.it stumbles then picks up or does it hesitate then pick up?

Thanks for responding. Flat spot.
The engine is the 4.2 S8 version which is the higher HP version than the standard 4.2 The hesitation traditionally occurs when I come to a near stop at a stop sign, maybe down to 2-3 mph and then give it gas. For a moment nothing happens. It is not a shift break and I have had too many cars to know that difference. However, of late, it actually getting worse at even higher speeds. Getting dangerous to drive. From day one, (new) dealer has always insisted it was normal and no longer will even write of the complaint. Out A 4 does not do this and a friends 2002 A8 does not do it either. Thinking software but am stumped. Thanks. Mike

As its a V8, I seem to remember that this is a symptom of the breather hoses at the back of the engine being perished and letting air in
There's a thread about it on the forum here.
