Question about 2005 Audi A6 3.2
After replacing the battery, all lights lit up brightly yet the car was still sluggish and unwilling to accelerate. The next day the car started as if it had been previously flooded because the AAA mechanic accelerated a lot to attempt to move the vehicle. Shortly thereafter, after moving it several feet, the pedal was to he floor. Simultaneously, it took the car nearly 20 minutes for the heating gauge to register between the cool and hot. Also, the amp would not move beyond 3.8. No matter how many times I attempted the acceleration would not go beyond 3.8 amps.
Clean your throttle body and check last time changed filters, air, fuel. Personally same situation happened too me but with different causes. Once bad fuel ( probably water/contaminated) and fixed that with ( thankfully had low fuel in tank) with five gallons of higher octane fuel and I also added an octant booster. It burned off the bad fuel but could difference in power fluctuations and once it burned it off I filled up again and no problem but, added a fuel treatment/cleaner for good measure as well. Now as for the second time my truck is throttle by wire which means it has a small stepper motor that controls the throttle and that is controlled by a rheostat linked to a pedal Instead on a cable as most older cars and
trucks have. The solution for me was to clean the throttle body with a standard throttle body cleaner I picked up at the local autoparts shop and with a clean rag. The "dirt" and contaminants that build with time will hinder the movement of the butterfly valve. If it stays closed engine just can't get enough air. After cleaning ( if that was your problem) you should get back the throttle response. If your like my girlfriend who lives near a big field with lots of squirrel's check for chewed up wires. Otherwise many things can cause the same type of problem with a different solution. Good luck.
