Throttle Body - New one arrived, I'll fit it tomorrow
I popped into Halfords for another identical one (Yuasa battery HSB020 - 5 year guarantee) and got a nice 20% discount from my old Trade Card, otherwise it'd have been £190 which is scandalous if you ask me!!!! Afterwards, as the cars ECU's had been been monitoring the slow degrade of the battery and they remember how poorly performing that battery was (and will pre-emptively adjust power levels for the bad battery), it now needs to be told that a new fresh battery is installed otherwise, yet again, it'll throw various error codes. However that was just a simple 5 minutes on my VCDS laptop where you change the serial number of the current battery to the new one (it needs to know the make, model and S/No of a bloody battery!), which tells the cars ECU's "hey this is a new battery, reset your power limits memory".

A few smaller things - Fitted the new throttle body a while back and all is good there, popped into MRC Tuning in Banbury during a weekend trip back to Stoke for an oil change (Fuchs Titan Race Pro-S 5w30). When we filled in my service book we realised it'd been over a year since the last service so got to get it booked in for a "minor" service in a few weeks time inc gearbox service/oil cx on top.

Is there a particular benefit to running 30? I’d be a lot happier with 40 for the power you are running. I ran Fuchs Pro-S 5W-40 for years based on an OpieOils discussion and the last time I was at MRC they gave me a lengthy chat as to why I should go back to 5W-30 but it was about 18 months ago so the specifics of the chat are hazy at best but I "think" it was something about the oil pump flow rates and/or seals - I'm really struggling to remember the chat TBH, my take-away was "go back to 5W30" is all I remember clearly.
Worst case I can swap back to 5W-40 if needs be.

A free fix of something on the RS6 - NEVER!!!! 
My car speakers started distorting, dropping out, crackling etc but only during full throttle and the sound returned to normal after braking. This was happening to both right side Front and Rear door speakers (6 in total, 3x per door) only so it wasn't a specific door issue and my initial "Oh god, now what!" thought was "if its everything on the right side of the car, its not the individual speakers or the wires to them" so it made sense to me that it was possibly the Bose Amp instead which runs everything.
However, after jumping on eBay and seeing the £300+ price of a 2nd hand amp I thought to myself "You're an aircraft tech dude, if this was a plane how would you fault diagnose this issue first rather than just replacing expensive bits on a hunch?" so before I went any further I did the following and found the free, simple fix to my specific problem -
Looks like after about 3+ years of not moving the iPod whilst it was in the glovebox tray, 'something' had tweaked/nudged/bumped the iPod connector so unplugging it & plugging it back in fixed the issue. As part of all the investigation, I also rediscovered - i.e. remember I ONLY use the iPod, nothing else for the past 9 years of ownership - that not only do I have a DAB radio (makes sense TBF) but I also have a TV Tuner as well
which I genuinely had no idea I had, so I spent a few minutes watching the BBC news whilst I was parked up.
Then I took it out for some WOT testing and, after almost 2L of Water/Meth had been used (40+ WOT's - maybe a little overkill), I'd say it's fixed and now I know what to look for in the future should this happen again.

- I unplugged the Bose amp and checked the connectors (two plugs - 1 massive "zero insertion force - ZIF" connector and one '2 wires' Fibre Optic connector) then plugged them back in.
- I use the iPod 100% of the the time and have done for 9 years, so does the sound also cut-out under other music sources like the Radio - No, it only cuts out using the iPod so that means that the Amp is OK (whew!).
- Unplug the iPod in the glovebox, check it with some headphones (both sides play music so iPod is OK), then plug it back in and test - HaHaHaHaHa - Fixed
