* 5570 - BT works a treat on my Nexus 4 so looks like this is sorted. Might still run the discs for peace of mind.

If 5570 seem to work and VCDS checks out, then don't mess with it.

The 5570 upgrade is a firmware upgrade, not a software upgrade, if you're in IT then you'll understand that this means you overwrite the bootloader when you upgrade, if there is any sort of glitch, powerloss etc., then the bootloader is likely to be corrupted, so the component is useless and has to be replaced. And you probably have 20+ components to upgrade. That is why Audi dealers are so reluctant to upgrade. If you have a definite reason to upgrade, because you know there is a problem, then go ahead, but there is a small risk that you'll have to replace something that is expensive and hard to reach.

Thanks for the comments guys. The 19" wheels were apparently a £2,000 option. The do look good The_IMF but wasted on me as I'm not really a wheels person. I'm was suspicious that bigger wheels meant lower profile tyres = worse ride quality however A6_Chris has indicated that this shouldn't be a problem.

As for the 5570 upgrade, I understand the need for caution Micha_elD but latest and greatest is in my blood and not knowing if the 5570 had been done properly would have eaten away at me. I do urge extra caution of course with this type of upgrade and for myself when I did my (thankfully departed) A6 this meant hours of online research ensuring I adopted all the best practices. This led to my buying (and using) a new battery charger and making sure I followed instructions to the letter. The whole procedure turned out to be completely painless. On the A8 I ran the disks (using the battery charger) but there were no updates required. Whew!

I'll try and get time to post a new thread about the Audi Universal Mobile Phone Cradle but for those reading this thread don't feel you need to buy the £28 USB lead with the cradle in the first instance, as I found I didn't need it with my Nexus 4.

Good to hear you did the research and understood the risks, every once in a while someone comes onto one of the forums having bricked a component by letting the battery go flat, or by using a poor copy of the original discs. And good to her you have a successful 5570 upgrade.

That battery charger approach is essential when working on one of these cars, mine has keyless locking, and it starts to power up the car as soon as you get near it. Once you switch on the ignition, my 8Ah charger can't keep up with the rate the car uses power
