Intermittent Fuel Starve or Plugs Firing Problem

Post by wazaB » Wed Jan 27, 2021 3:10 pm

I have the 2020 model as well and have found that when driving over 50mph in any mode, including manual and cruise, there are occasional small drops in power.

It feels like 1 or more cylinders are being starved of fuel or a plug or 2 just not firing!

Its done this from around 1 month old.

Anyone had this or similar?

Thanks

Just a thought - when I had my 2018 RS4 I noticed that there would be occasions when the 'D' symbol would disappear - if the Power/Torque VC display was up then both would go to zero. I assumed that the RS was in overrun/coasting and the engine wasn't generating power. Could that be the case for yours?

No nothing changed other than this strange fault
