Re: Vibration while accelerating – 08-12-2015, 09:19 PM. No. On P, D, N and R no vibrations while staying in place. Yesterday took the car for a spin on cold engine and gearbox did a sprint.. no vibrations. After that left the car for 1 hour and took it again cold out for a spin and felt slight vibrations. How much is the ported blower, oh wait & don’t forget to upgrade the heat xchanger on the blower or you’ll melt it. for $7500 bucks the 4.0 has 700-750hp. $7500 on a 3.0 only pays for the blower. The 4.0 is the first motor where Audi was able to push the motor further back in the engine bay. Acceleration test 0-100 of Audi A6 Avant 3.0 TDI 150kW 2012.

Recently I have been experiencing hesitation when accelerating from a standstill (junctions/roundabouts) like it will go forward then almost pause for 1-2 seconds before launching forward. The focus is on the engine, a single-turbo 3.0 TDI that makes 284 horsepower and 620 Nm of torque. This is the same output as in older Audis, such as the Q7. However, the TDI has been fitted with All specifications, performance and fuel economy data of Audi A6 3.0 TDI Competition Quattro Tiptronic (240 kW / 326 PS / 322 hp), edition of the year 2016 for Europe , including acceleration times 0-60 mph, 0-100 mph, 0-100 km/h, 0-200 km/h, quarter mile time, top speed, mileage and fuel economy, power-to-weight ratio, dimensions, drag coefficient, etc. samisnake. as davey mentioned, check there is nothing behind the pedal like a stone or piece of mat, try to get compressed air in there (pound shop do a can.for a pound). if that doesnt work id then remove the pedal and inspect. if cant see anything, or cannot fix it, id then look into a replacement pedal. This car is insane. So quiet, so calm, so comfy and even more, it's so easy to reach absurd cruising speed in this family ship. We love A6 3.0 BiTDI, that's By Tom Torbjornsen. May 16, 2016. CARS.COM. The problem: Affected vehicles may exhibit a rough engine idle and hesitation/stumble on acceleration. This may be due to a faulty mass airflow sensor E786.
