Hi all tuning boxes work on the same principle they plug into the fuel rail and fool the car into thinking its running cold all the time therefore it runs richer this in turn allows over fuelling which washes the bores and the pistons, so in conclusion it looks like the remap is the better option as that controls the fuelling in the correct manner commensurate with throttle demand and not the boxes way of lets throw extra fuel in an see what happens.

Hi if you take the top plastic cover off above the radiator which from memory is two plastic plunge clips that should give you a better view of it all, mark where each pulley touches the belt with tippex and do a drawing of each pulley and the way the belt travels either behind or over that particular pulley, good kit Dayco and INA are used as o.e., I wouldn't get involved with changing the alternator freewheel clutch in situ as they can be an absolute cow when the alternator is out of the car and on a bench these clutches normally fail way after the alternator and as most replacement alternators have a new clutch fitted its probably a fruitless and consuming exercise, only other tip is make sure you have the belt running true when you pull the tension pin out to release the spring tensioner as you will need Neanderthal strength to pull it back again if you get it wrong and remember to turn the engine over by hand a few turns to settle the ribs on the belt into their grooves, I have seen the new belts try and ride off of the crank pulley.

Hi if your talking about the green menu I would steer well clear of it unless you are totally at home with the adjustments to be done as if you get it wrong you can FRY the MMI and oh boy is that an expensive hobby.

Hi they all do it not just Audis, when I was running Mondeos that was there favourite trick as well as spreading foam crumbs all over the carpet I used to go down the breakers and find a car that was picked clean and buy the passenger seat foam and use that as it had less wear, I think the new foam is probably your best bet and is easily fitted so that will be it for another 168k by which time I think you will be past caring LOL.
