So it turns out my car is Pistonheads "Car of the Week" which is nice.

To be honest it would have been better if PH had actually read the thread instead of skimming it as they got so many things wrong in the story they wrote.

Thanks anyway PH!!!

Realised I'm a dumbass - After the car felt down on power for a few days I switched my glovebox mounted water/meth unit back On. I'd removed the protective cover to show a friend the gauge and my pair of emergency "cinema" 3D glasses had bumped into it whilst driving which had switched it off!

Update time - New brakes arrived!!!!

AP Racing 410mm discs mated to Radi-Cal CP8522 Calipers mounted on custom made brackets by BG Developments who do all of AP Racings Customs work. I've also got AP Racings DS-25pads (Ferodo DS2500 compound), HEL brake lines and Castrol SRF fluid.

I'm doing the ASDA charity trackday again on the 6th so, now I've got an extra 180hp over last year, we'll see how they cope with multiple 175+ to 30mph stops. Last year when I was at 730hp the OEM Caliper with AP- Racing 390mm discs, DS2500 pads and ATE Superblue fluid it did 49 160+ to 30mph stops with only a tiny bit of fade in stopping power but a longer pedal travel throughout the day so I'm hoping for much better from these.

Once I get these fitted on the 2nd I'll put up a full review with more pics and fitting guide etc.

My Rear Diff - IT GO BOOOOOOMMMMM!!!!!!

Well it's more of whine to be more accurate (sorry the click-bait )

With a 100k+ mile car pushing 900hp+ for the last 8000 miles it's no wonder there was going to be a weak spot found eventually. I was expecting it to be a driveshaft TBH but the rear diff was also a worry (front diff/transfer box all in uprated GB) as well as potentially the wheel bearings (replaced during 900 conversion).

I dropped it off at the garage last night and they've just confirmed the bearings had failed and were making some quite impressive noise on the lift

So heres my symptoms and a quick vid of the noise for those who are interested -

Whine only present when pressing the throttle, even just 1-2%. No whine when off throttle.
Noise is road speed dependant not gear/rev. I tried 2nd-6th at 40mph so 5500rpm to 1500rpm and the whine stays the same.
Noise starts from 20mph to 100+ and the whine starts as a low freq low volume noise. At 40 and 60mph the volume peaks (resonance) and then rises to extremely high freq low volume by 100mph+.
Cornering & bumps have no effect on the noise nor does braking (if you keep the throttle pressed too).
Passenger's in the back seat at the time said there was "buzzing" by their feet under load.
The rest of the car drives, stops & handles exactly as before but the MPG was down slightly (6 less MPG shown when doing 60mph on a motorway) due to the increased drag in the drivetrain.

In the video I'm just tapping the accelerator a tiny amount every 1-2 seconds so the noise appears/disappears making it easier to hear the difference.

So my initial plan was to check with Audi for costs/time for a new one. After the call I had a cry and a sit down (which was very difficult considering the vigorous bumming Audi* gave me) and then got around to finding a decent gearbox place in Kent to get it rebuilt instead for under half the price of a new one. It should be all back running next week with my new brakes fitted, new diff and a considerably lighter wallet!

PS Warranties are very important! If your current one runs out and can't be extended (car now over 100k miles) then get another one pronto! Doh!

*Audi wanted 4300 with an unspecified waiting time as they had none anywhere, not even in Germany.

Yay got my car back with a new rear diff and the AP Racing 410mm Radi-Cal setup with custom braided brake lines.

Boo the brakes need more bleeding as the pedal feels too soft, even though the brakes work.

Brakes re-bled (got some air out) and pads bedded releasing a vast quantity of smoke and the brakes are stunning!!!

I'm hitting the tyres grip limit at *well* above motorway speeds which is much better than before where it braked strongly down from high speed to 70mph-ish before starting to chirp the tyres.

Now I just need to sort the knocking from the OSF DRC strut which is leaking at a union in the arch. I've got a 10k servicing, GB service and DRC re-pressurisation at Unit20 in a few weeks so hopefully everything will be well afterwards!!!
