My warranty covers the whole unit with a £50 excess.

would i be better to get the unit replaced for £50 inc labour and new arms, or just buy the aftermarket arms?

and just making sure it covers D3's 4.2s

Just to add my 2p worth.

These things actually make a difference if not working ( if not working properly, they make the car a lot less powerful and it uses more fuel)- and they need to work even for low power settings.

My n/s one was stuck, but when fixed the car was noticably both more powerful and fuel efficient, especially at LOW power levels. ie in normal driving, once fixed, it needed less pedal for the same result.

Both bellows should collapse (and operate the things they're attached to) on startup.

My cars average fuel DIS was 23.1 mpg before I fixed it. Now it's 21.3.

It's done 30,000 miles since I last reset it, so it must be WAY more fuel efficient than it was.

What? It uses more fuel now you've fixed them?

Had I known I might have been tempted to leave mine broken instead of ordering those classy-looking Gruvenparts items...

I was only in Atlanta a few weeks ago and could have bought a job lot back with me had I read this thread before I flew home!

I gotta ask the same. I just hope the numbers are mixed?

Ahem.... that was a typo.

Now 23.3. Whoopie-Do!

I've done about 20,000 miles at '23.1', so for the miles since the repair to have built that average mpg up to '23.3' I reckon the car might be doing 24 mpg????

Who cares. It shows the car goes better (faster/ better mpg) with them working.

I love the S8, but them fill ups r hurtin!

Having driven my "new" FL S8 a fair bit in the last few days I'm beginning to think it may have this problem.
It's nice and urgent at low speeds and low revs, but feels decidedly sluggish above 3000rpm compared to my PF model, which had twice the mileage.

Is it easy to get the relevant covers off to check - any photos I can be pointed at to see what's involved?

I found this pointing at the components to check, but no idea how to get to that view. http://forums.audiworld.com/showthread.php?t=2801728
