A6 Avant 50 TDI Quattro sluggish at times

Recommended Posts

I’ve had my new A6 Avant for about a month now and on the whole am very happy with it. I have the drive mode set to Auto, although have also tried it in sport mode, and quite often when pulling away, the engine revs quite high but the car takes a while to actually move and get up to speed, almost as if it’s struggling to actually get it into gear. I had one scary moment on a busy roundabout where I put my foot down to get away quickly, and nothing happened for the first second or so. It did eventually kick in and shot off like a rocket! But other times, like when I drove tonight, it’s really responsive.

The whole reason for getting the 3 litre model was for its performance, but there’s no point in supposedly having 0-60 in 5.7 secs when nothing happens for the first second or so.

Any ideas why this might be? Could it just be the software needs refining?

Thanks.

I heard its the 8 speed tiptronic gearbox that's the problem. Apparently the 7 speed s tronic on the smaller engines is a lot better.

It's been a 'feature' of Audi gearboxes for a while. My previous A6 (2.0 TDI) and new A6 (40 TDI) both suffer from the same - it's like a delay of 0.25-0.5 seconds when you put your foot down and is very annoying. I can only think that's it's a deliberate delay (as everything is electronic) to allow something to happen - realign gears perhaps.

I'm interested to see if a remap could address this but as yet, haven't found a map that can easily revert to 'normal' before any service (company car).

I had an A6 Avant before this (2 litre) and an A5 before that and can’t say I noticed delays as dramatic as in my new car. The other cars were S tronic’s whereas this new one is a Tipronic. Could this be why?

It’s going into my dealership next month for them to look at. I really hope they are able to do something as the whole point of buying a 3 litre Quattro is to have good performance. If they tell me it’s behaving as expected, then surely I can claim that the car is not fit for purpose and get my, quite considerable amount of, money back? I’d argue that such a huge delay is dangerous.

I do wonder if there’s something wrong with the CPU as I’ve had several other issues - lost all my shortcuts the other day, and twice the cameras have failed when trying to reverse into a parking space. And today coming home, using a route I’ve used loads of times, the green triangle on the speedo which shows me what the speed limit is was wrong twice. It’s not done this before.

I am concerned at this too. I have just ordered same car and having test driven felt it was a real problem. I currently have V6 bi turbo C7 and its pick up is excellent. I was considering new S6 but lease costs are prohibitive compared to standard models ( 8.5% more on list price to car I have ordered and 48% increase in monthly lease cost!!).

i intend to fit a DTUK box of tricks and a pedal box to assist throttle response which I am told works well.

Hello Mike,

Apologies in advance, but are you really ordering a new car following ‘a real problem’ on a test drive example? If so, I guess Audi could be entitled to dismiss a claim for ‘unsuitable for purpose’ - as Wooks63 was considering to do- since you knew it’s pitfalls before ordering. 

Ref. fitting a box of tricks to overcome this issue, straight away brings to mind invalidating the warranty. None of this is where I would want to be spending  my money, in anticipation of discontents. 

Good luck if you do go ahead.

Kind regards,

Gareth.

I took my car into my dealership. They reckoned that the car was performing how they expected it to, but they did make some adjustments to the gearbox. Since then, the changing up of gears is now very smooth (previously it was quite jerky) and pickup seems to have improved, although I’ve still had the odd occasion when I’ve floored the gas and absolutely nothing happens for what seems ages. I was told that there is a software update coming for the car to address several issues, so I’m hoping that as the software matures, the car will get better.

I’ve just got to teach myself that slowly increasing pressure on the gas rather than flooring it gets better results.

How are you finding it now OP? I have recently received my new A6 45 tfsi which has the S Tronic. Performance is lightly less than the 50 TDI (0-60 is 6 seconds). It also has a bit of a delay if you floor it hard like how you describe. Feels like it's just taking time to drop down a couple of gears to respond to the request for more torque. I find if I use the paddles; a couple of quick flicks on the down shift paddle to drop it down couple of gears manually, the response is much better when I want that quick burst of acceleration. Have you tried that?  Out of interest, what mpg are you getting with mixed driving?

I have also had this in my 40 tdi - I have worked around it, not ideal, but if I blip the throttle before I want to 'Go go' then it kind of moves into gear - when that small gap shows, nail it and it moves fast.

I wanted an auto all of the time I had my C7, but I miss it a bit - This seems to be all over the gears and change up way to early for my liking

Sorry for the delay in replying.

On the whole, performance is good and a lot smoother now that the dealership made some modifications. I still get the occasional delay when flooring it. Agree that it definitely seems to be the car not dropping down gears fast enough. Will try manually dropping down next time I need to get away quickly. 

Am very pleased with the fuel consumption. Did a long journey the other day, mainly motorway driving, and was getting 50mpg. From memory, driving locally usually gives me around 30-35mpg.
