I'd just like to add I had the same problem, 2012 A6 3.0tdi with 2 zone climate. I bought the car with 44k miles, full history and it was a very clean and well looked after car.
I soon realised the heater was virtually nonexistent. Being a mechanic myself, I rather look myself than take it...
I am on my second set of PS4's. The first set lasted me 33k miles, they could have done another 2-4k if I took them right down to the legal limit. Most of my drive to work is country roads too, so lots of corners, braking & accelerating. I've seen people easily do 40-50k on them with motorway miles.
I will be fitting them myself as I'm a mechanic :) I will probably go with springs for now, and then get shocks in 6-12 months time. It's come at a bad time while I'm rebuilding a project car right now.
But it would have failed as a result of being clogged up and not being able to function properly. Having a diesel to do an average of 3,300 miles a year is silly, you would save money having a petrol. You want to be doing 10k+ in a diesel to keep it happy.
That's what I'm after really so sounds good :)
Thanks for your reply, it's not a huge drop I'm after, just something subtle to close the arch gaps up a bit. I will look into the B8's.
I've had lowered cars since I was 17 so well and truly used to it haha. But the extra 5-10mm drop I'm after...
I've got a broken spring on the front and using it as an excuse to improve things a bit. I find the S-line suspension is ****** hard, although it handles fairly well for factory suspension. The original shocks are on 93k so it would be silly not to replace them especially when lowering...
I've now got an Xtrons 8-Core unit. BOSE Sound is fantastic, rear speakers are great, tons of bass from the sub, very loud too and sound quality is really good. Plugged in with everything out the box, no extras.
From what I have read on here, it's this: http://xtrons.co.uk/pb76aa3p-7-hd-digital-octa-core-64bit-32gb-2g-ram-android-6-multi-touch-screen-car-dvd-player-custom-fit-for-audi-a3-s3-rs3.html
I'm looking to replace my RNS-E Mk2 with one soon.
