Hi Jason,

I have had all of these issues and Audi are still trying to fix them. In total they have had my car for a total of 4 weeks and all issues are still not resolved. The dealership also bumped my car whilst at the garage and did not own up to it!!!

Not happy at all, my previous A6 was faultless and such a great car!

Sorry to be so negative but not the service you want from an Audi dealership.

Hello,

I have a 2019 A6 (C8) avant with the 40tdi engine. My car does a irritating humming/buzzing sound which at first i thought to be from an unbalanced AC fan but soon discovered its not as i turned the AC off, the humming persisted. I had also noted that this noise changes in tone when slightly pressing the accelerator, so it is connected to fuel supply to the engine.  I have recently discovered its source when I began using the start-stop function (which i did not used), as when the engine is stopped as i stop in traffic, the noise can be clearly heard (without beeing masked by engine noise) for 1-2 secs and then it stops to reappear again as soon as engine starts. It is clearly a pump noise and it is located under the passenger seat (my car is LHD).

before this A6 I had a Q5 and the fuel filter was located under the passenger seat but had no pump. Maybe Audi moved the primary pump to this location or set a new pump on the fuel circuit, as there is also one pump on the tank (I car hear that too). I could not find any service manual or diagrams for this car, so I cannot tell for sure.

I did not take the car to the dealer but i am planning on do it soon as this noise drives me mad.

Hi,

Thanks for the note, It looks like Audi are going to install a new fuel pump, it is on back order but the service technician said it looks like they are changing the pump design due to the noice. My car is booked in again for the 10th Feb and they want it for a week!

Hi,

The fuel pump on my A6 Avant is very noisy, is anyone also have this issue?

I did not receive them either so not sure if they come with the car.

Hi, I have had the rattle from the centre console, this issue is the gap between the bottom centre console and the upper console. There is a fix for this but you need to take it into the garage. I have also had issues with the headlights, I have the auto main beam LED system where it switches on and off different LED's to give max coverage, been getting a lot of other drivers flashing me, took it in to then garage and they have dropped the hight but still getting flashed.

I also have a problem when taking a very slow tight turn, it feels as if the front wheels are braking loose from the ground, has anyone had this issue? I also think that the car has very poor traction when pulling away from junctions when the road is slightly damp, the front wheels start to spin but the traction control system does not activate!!

My car is the New 68 reg Avant 40 TDI front wheel drive.
