Road Noise?

My wife currently has a MK2 Tdi Roadster S-line Special edition.

She has been considering upgrading to the Mk3 for a while and has been playing with the build your Audi feature quite a bit. Last week my A5 had to go in for warranty work (It is expected to be with them for several days) and I managed to obtain a brand new, registered first week in March, TT roadster for the week :)

The car is an optioned up black 1.8 S-line with the optional 19 inch twin spoke alloy wheels fitted with Bridgestone tyres. The car obviously looks very pretty and things like the cool steering wheel, heater controls in the vents and the in dash navigation are fabulous. Less nice are the motor, the handling and the road noise.

The motor has to be worked to get the car to feel even slightly nippy. But all that revving really effects the economy and to be frank even when we've tried to get economy we've struggled to the car to deliver mid 30's :(

Handling - Our old TT drives like it's on rails with super fast turn in, it's like driving a go-kart. The new TT, that we have, seems far less direct. The car does seem to sit a lot higher, maybe the car hasn't got the lowered sports suspension? All I know is that it doesn't feel anywhere near as much fun :(

But saving the worst till last - road noise. My A5 3.0 black, on 19 inch rims is near silent inside. I have always found the wife's TT to be a little noisy but this new TT is terrible. You actually have to raise your voice to talk, and keep turning the radio up and down to over the racket coming from the wheels / tyres when the car is moving. It is so bad that it has actually put my wife off the whole upgrade idea. Have any of you who upgraded noticed this or could it just be an issue with this car and its suspension / wheel & tyre combination?

18 months ago I had an A5 V6 3.0 diesel S-line convertible for a couple of weeks. Whilst on paper it was significantly quicker than my TT it rarely felt like it. Apart from a long lag between putting your foot down and then getting the push in the back the refinement and softness of the car insulated you from much of the feel of the road. On top of that it drank diesel quicker than my 1.8 drank petrol.
My car has no lag and is far from soft, especially in dynamic mode. The DSG, sport diff and active suspension make for one very tight and very quick car. If you are sure you drove a 3.0, and not a 2.7 V6, then it must have been the 3.0 204ps version with the multitronic.

Anyhow I have been out for another spin with the 1.8 TT today, it was sunny so I just had to get the roof down too :) I headed through the country lanes making some swift progress but not thrashing the car. I really enjoyed the drive but was somewhat disappointed to see sub 32mpg on the trip. So I re-set it and took a 65mph run along the dual carriageway for about 30 miles - mpg 33.9 :? Surely it should be much better than that? Oh and YES I am using 6th gear, and I've checked tyre pressures too :eek:

When I collected this car it said range 100 miles. I had to put fuel in well before 100 miles but ÂŁ20 gave me another 100 miles indicated range. After about 70 miles I had a fuel light again, so another ÂŁ20 was deposited and again indicated range of 100 miles. Thus far I've put ÂŁ40 of petrol in this car and currently have a range of just 50 miles left. But I've covered fewer than 200 miles. ÂŁ60 of diesel in my A5 regularly returns 400+ miles - calculated to roughly 37mpg. My wife's 2.0 Tdi TT almost always returns mid 40's even into the 50's on a long run.

This evening I collected a friend, another Audi nut with a 2013 TTS roadster, his first words "Wow - that is one cool dash set up, but what's with the road noise?"

I really want to like this car but I am sadly finding it frustrating. If we do decide to replace the wife's roadster we will need to get a long term test drive of the model she wants before we place any order. Based upon this car it won't be a 1.8 petrol :(

Go for the diesel model maybe.
All the negative press on diesels is giving the government a green light to impose higher costs on new diesels cars, with rumours it may even be applied retrospectively. This is why we were thinking of going back to petrol and the 1.8 seemed, on paper, like the perfect model to replace the tdi TT.

As I move closer to retirement an RS would also be a more viable option for me too. It would be nice to get an Audi 5 cylinder turbo back in my life :twisted:

I then had a TT roadster quattro s-tronic s-line on Bridgestone tyres. Having been driving the A5s for a month beforehand, the road noise came as a bit of a shock. It was about as far removed from the A5 as I could imagine.
This is exactly what I was wondering. Is it just tyres.
Our MK2 TT is on Goodyear and it is significantly quieter than this car currently is. OK it's not A5 quiet but I am not silly enough to be expecting it to be.

Can't comment on the 1.8's fuel economy but I find the idea of expecting mid 30s out of a petrol TT fairly farcical.
Your farcical comment should surely be aimed at the claims made in the Audi TT brochure, not my expectation. The combined MPG figure that Audi give for or the 1.8 roadster is 46.3 mpg, an extra urban claim of 54.3 and the urban figure is 36.7mpg.

If I were able to achieve the urban figure it would be a start. I was starting to think that perhaps the trip computer had been set to US mpg.

26mpg for a TTS is worse than what some of the TTRS peeps are reporting :eek:

Went for a run a weekend Stockport to Telford down the A49 and back, got 42 mpg if you believe the trip meter. Thats in my 1.8 S line.
Now that is more like it. My wife has a 25 mile each way commute so figures like this could make the 1.8 a more viable option to the diesel, thanks :)

One more A5 rotor to clean and polish and I'll go for a spin....

EDIT

I set the car into Efficiency mode got the car warmed up and re-set the trip. I then took a drive to Newmarket on the dual carriageway at a steady 65 mph. I watched the numbers rise and for the first time saw the trip record over 40mpg before I exited the A14 and drove into town -38.9 by the time I parked up :)

Got back into the car, quite a lot of traffic so came back home along the green lanes. I arrived home with 37.8 still showing so it does seem to be slowly improving :D

This little car is really growing on me but I do really want my A5 back

Question, please, the A5 rotors that you talk about obviously fits your TT, what size and if you don't mind where did you come by them?
The A5 rotors are from my A5, which is currently on winter wheels and stuck in the Audi dealership :( I do wish that the A5 and TT MK2 wheels were interchangeable but the offsets are miles off. I also have no idea what the off sets are for the MK3 TT

As previously stated in this thread - it all depends on what you are comparing the TT with - yes, it's no limo but it's much quieter that a Boxster I can assure you :eek:
As previously stated - Our Mk2 TT TDi S-line Roadster ;)

OK peeps car went back today. I called up Audi yesterday and they added my wife to the car so she could drive it.

Got a call from her today after taking it back. She said she really couldn't live with the road noise with the roof up! It's not all bad though as she's looked over a Mk2 roadster Amplified black edition and wants to trade up to one of those, so a bit of a saving over a MK3 :)

Now to try and find a one, TDi in Orange, red or Daytona. They all seem to be in white :(

Not sure if you peeps cross borders into the other groups but Mrs BB has gone with a late MK2 Amplified Black. She collects it tomorrow :)

Bit of a shame that she didn't gel with the Mk3 but I am fairly sure we'll be back. I do need to get a bit closer to retirement to be able to justify the RS though :(
