Hi all, my name's Ian and for my first post I thought I'd introduce myself and my RS6 with this car diary. I'll update it with everything that happens whilst I own it.



Bought - 20th Dec '13 - It was completely standard (except for being de-badged) and I'm the third owner, with the 1st one taking obvious care of it with a service book full of Audi stamps and receipts for nearly 9 years while the 2nd owner appeared "more relaxed" about the maintenance side of ownership for the year he owned it before part-exchanging. For a ten year old car it's in extremely good condition. The paint work only has 2 very minor scratches, the engine bay is spotless, the interior looks brand new and it's had the brakes & timing belt replaced 10K miles ago. No 2nd hand car is perfect and this hold true here although the problems are minor. The Left Rear mid-bass speaker is blown (works but sound crackly/farty), the paint had bubbled on one of the rear parking sensors intermittently sending the system haywire (see's a object when there not) and the Carbon Fibre ash-tray trim piece is loose. Not bad really!













28th Dec '13 - Visited MRC for the Following - Gearbox service, 20K service inc MAF's/DV's/N75 replacement, Health check, 2x MRC Air Filters and a brake fluid change followed by a Stage 1+ remap (engine and gearbox ECU) giving 500hp and 600ft/lbs (probably 550ft/lbs without the torque converter bump). They found a few issues which will be sorted later next month and cured a cruise control issue after it had been mapped out during a previous owners attempt at re-mapping.

31st Dec '13 - Replaced the RNS-D with an Alpine INE-W925R head unit with more connectivity than you could shake a stick at and including DAB & Sat Nav, meaning the standard aerial has been replaced with a "sharks-fin" style one due to the different DAB/GPS aerials.



4th Jan '14 - Got a 4 wheel Alignment. Not that far off but there's a strange high frequency vibration at 70+mph that's not been cured by this or having the wheels rebalanced.

6th Jan '14 - Took the left rear door trim apart to fix the crackly speaker by replacing it and replaced the interior lights with LED's.

16th Jan '14 - Replaced the loose Carbon Fibre trim piece from the Ashtray.

23rd Jan '14 - Fitted 4x Goodyear Eagle Asymmetric 2's in 255/35-19 size.

28th Jan '14 - Visited MRC again to fix the issues found during the 20K service. This included a Cam Belt change inc water pump and tensioners, replacing a rear brake calliper, fitting Zimmerman front brake discs and Ferodo DS2500 pads, 2x new front upper arms, a rear tie rod, replaced the leaky rocker cover gaskets and finally grinding the knobs off the front suspension arms to avoid damaging the tyres.

8th Mar '14 - Replaced the Gearbox at Unit20 after it started to slip in 2nd at full throttle and shuffled between 3rd-4th at part throttle. While the box was out I also had the EGT's, Lambda's, Water/Oil cooler bobbin and the oil feed pipes replaced too.

15th Mar '14 - Took advantage of the lovely weather to give her a quick wash and take some pics -











17th Mar '14 - After the lovely weather at the weekend I found that my AirCon was a bit weedy so had it regassed at Merityre in Witney. Took an hour and cost £54.

18th Mar '14 - Gave her yet another wash to remove all the sandy that covered her then took a few pics and did a quick 0-60+ test.









0-60mph in 3.9 seconds in a 2 ton estate, I really LOVE this car!



26th Mar '14 - Finished off the Interior Light LED install, fitted whiter 5000K bulbs to the headlights (OEM is 4300K), better LED side Lights (white not blue/white) and somehow fixed a broken HID ballast by wiggling a cable.











31st Mar '14 - Met up with another RS6 owner to give her my old GPS Aerial and have a quick passenger ride in her car to check out her cars suspension as mine is starting to feel a bit shot. Love the KW suspension she has fitted but her juddery rear brakes (new pads) weren't nice!



6th Apr '14 - Had a mini-meet and blast around the Cotswolds with a bunch of B5 RS4 owners and found out that an RS4 in your rear view mirror is a menacing sight! A fantastic day!









13th April '14 - With the weather turning Sunday into a fantastic driving day I popped into Blenheim Palace after another blast around the Cotswolds, the south eastern half this time. I didn't want to pay the £5 entrance fee just to get a picture so took this on the driveway instead.



17th April '14 - The state of my alloys had always concerned me since I picked up the car. A previous owner had got them refurbed and the job was done so poorly so that by the time I owned her the paint was flaking off all 4 wheels in large chunks with the inner faces losing 90% of the paint and there was a distinct vibration that weights couldn't cure.

I took the alloys to Platinum Wheel Refurb in Swindon based on a huge review thread on PistonHeads. A week and £400 later I've got lovely looking alloys and the vibration has gone after straightening the 2 buckled alloys! Here's a pic - Nothing special added or done to them, they've just been returned to "As New" condition in their original colour.

Also really need to get a proper detailing done with colour correction as my paint is quite "orange peely" to my eyes when you see it upclose.



Cheers for reading.......................................Ian

Ved - I keep everything other than petrol receipts! When I sold my old RB26 engined R34 GTT I had 2 box folders full of receipts for absolutely everything and I found that it gave any potential new owners a reassuring feeling that the car had been looked after well when they could go back through 6+ years of receipts.

ecain63 - Here's my dyno run from MRC, the TQ bumps it up to 820nm (600ft/lbs) at 3000rpm but it's stable at 750nm (550ft/lbs) throughout 3500 to 5000rpm before tailing off to 600nm (440ft/lbs) at redline. I did mention those figures the above post (600 but probably 550)



I worked for a few rally teams in Scotland (Rhino Rally, Moray Phoenix and Fox Rally) doing in-car cameras and GPS timing etc and my 0-60 time was measured using a 10hz GPS receiver (Q-Starz BT-Q818XT) which has the same accuracy as the racelogic v-box unit. However, that particular 0-60 used left foot braking to hold the revs upto 2000rpm which isn't very healthy for a TQ so I only did it once. Normally it's around 4.1-4.2 seconds -

BlimeyCharlie - You'd be right too biggrin Before I post these up please bear in mind that I'm a massive fan of Over Maintenance and I'd like to keep the car for at least 3-5 years and will therefore have gone well overboard with my maintenance program i.e replaced bits that probably didn't need doing right away but would probably have needed doing sooner rather than later and, seen as the engine/gearbox had to be removed, what the hell lets change them!

Since Dec when I bought it my current maintenance bill stands at nearly £15,000 which sounds crazy, trust me I know! I've had virtually everything replaced that can be replaced like MAF's, DV's, N75, Lambdas, EGR's, Gearbox, oil pipes, Cambelt, Front Brake Discs/Pads, 4 tyres, 4 refurbed alloys, Front and rear suspension arms, rear brake caliper, oils, filters, gaskets, new Alpine Head Unit and I've also had £600+ of mapping for the ECU/TCU but Labour has been the biggest figure, over £8000 just in labour so far. If I really had to I could have not bothered with the 2nd service and gearbox and saved £10K this year but it would have needed doing soon and may have caused further issues if I'd left it any longer.

My last thing is the suspension as the right rear DRC is starting to fail so there's another £2000 on some Bilsteins etc.

HOWEVER, and it is a big HOWEVER, after this the car will be perfect and should give me a few years of stress free driving, until the manifolds crack and blow the turbos (another £4000) or the alternator goes (£1000) etc, oh the joys!

There's are a few lucky people that have bought theirs and only spent around £1000 over 3 years of ownership but I'd say the average is upto £3000 a year as various bits need replacing (cambelt £1k, Brakes £1k (front or rear), service £500-£1k etc etc).

Here's an actual breakdown of my costs in rough chronological order

Replacement CF Trim pieces - £70
Headunit/Aerial & fitting - £1400
Service/mapping - £2200
4 Tyres and Alignment - £420
Cambelt, Front brakes, fix bits bits found during service - £4000
Gearbox, EGR's etc - £5900
Aircon Recharge - £55
Alloys Refurb - £430

Owing one of these is not for the faint walleted, it's a shame the price is now low enough that people can afford to buy one on a budget but can't afford to maintain it and so they become passed on quickly lowering the residuals.

Piers1 - I only live a few miles from work so I cycle and just use the RS6 as a weekend car mainly so day to day costs aren't bad (£80-160 a month in petrol) once the big costs are done with.

Ved - It was a full service rather than my hastily typed re-gas, took about an hour on the machine, redid the oils as well as an anti-bac and then a re-gas.

I'd say that mine was definitely the best "Q-Car" there. I really love the other RS's there, especially the new RS4 and the older satin wrapped RS4 but they all look very aggressive, leaving you in no doubt that it's a powerful car but my RS just looks like a fairly normal A6 next to all these until you put your foot down and rocket off leaving "none-car" people amazed at what an estate just did and thats something that keeps me giggling to myself with every overtake biggrin

The noise of the B6/7 RS4 is something else though, absolutely gorgeous V8 noise from the Silver one with a JB Fab custom exhaust!

18th May 2014 - I went to the Caring with Cars charity rally for the Children's Hospice South West at Charlton Farm. Around 600 cars of all shapes, sizes and engine power from PistonHeads all packed into the grounds to help raise money for the Hospice.

There must have been 15+ Ferraris, 40+ Porsches, 50+ TVR's and MX5's and some really rare cars too like an RS200, Jaguar XJR15 and even a single Audi C5 RS6!!!!

31st May 2014 - I got back from marshalling & spectating at the Jim Clark Rally earlier yesterday and wanted to send my condolences out to the families of those involved in the terrible events of yesterday.

Myself and a friend had gone up to support a good friend of ours who was due to be a Nav on the Sunday Rally and, to make a weekend of it, after watching the Rally start in Duns on Friday night we all volunteered to be Marshallers on the Saturday at the Eccles Stage. I'm normally busy in the service area during our rallies so I was chuffed to actually get out on the stages and watch the action. Sadly seeing the flow of competitors slow to a trickle followed by hearing the fleet of sirens approach our stage is something that made a lasting impression which must pail compared to those involved in the Swinton stage where the fatalities occurred and my thoughts go out to them also.

7th June 2014 - Went to the Stoke Poges Summer Fete with some fellow car enthusiasts doing passenger rides. The weather started out badly but by 12:30 it was glorious sunshine! As well as the Aston there was a stunning Porsche Carrera GT, a huge Dodge Challenger and a vast range of TVR's.

12th June 2014 - Had new suspension fitted. After upgrading from a Mk3 Mondeo in December I thought the RS handled quite well for a big old barge but nowhere near as well as my R34 did and at low speeds (<20mph) the rear felt very loose, especially on right turns if there was a bump mid-turn. Plus the rear made all sorts of noises over bumps. Soon afterwards both MRC and Unit20 told me that, unsurprisingly, the DRC suspension was shot.

Jump forward to today and I've just had a set of Bilsteins PSS9's and uprated H&R ARB's fitted and the difference is phenomenal. On the way back from MRC via a bunch of back roads the confidence I had from the new setup was great and I regularly hit corners 30+mph faster than before (I know the roads very well!) without any feeling of dread.

The car now handles how it should have done from the start although I'd love to have a drive of a car with fully working DRC just to compare. It's currently set at as close to stock height as possible with the dampers set to 4 which gives a better ride than the knackered DRC did and doesn't feel crashy on Oxfords very pot-holed roads.

This was the 3rd set of DRC to fail on my car in the 80,000 miles since new and each set can cost upto £2k to sort hence the replacement with aftermarket.

So overall a working set of suspension is awesome!!

  • *EDIT*** - Now got some photos!

26th June 2014 - Chopped off the rear silencers and fitted straight through pipes instead to unleash some serious V8 noise.

My Reason for this is that I'm doing quite a few car events/meets/trips etc over the summer (pretty much 1-2 a week) and the stock exhaust is just too quiet so what I've done is remove the backboxes to unleash more V8/turbo noise (no extra power I realise) and fit a straight through pipe from just behind the resonators (keeping them to reduce drone at motorway speeds). However, as this is my daily driver I want this to be reversible so I've sleeved the remaining stock exhaust allowing me to swap between either the stock backboxes or the straight through pipes depending on what I'm doing i.e backboxes for mon-fri (and when selling) and then straight through for sat-sun when doing trips and the swap only takes around 10mins!

***EDIT*** -------------------------------------------------------------

Well, that makes a big difference! Had the brace bar welding across this morning and driven down to Alresford and all the 1800-2300rpm resonance drone (and slight vibration felt through your feet) has gone and the exhaust note has increased in pitch slightly. It almost sounds like a nasally Subaru boxer 4 (best example I can think of). I "think", although it may be me thinking too hard to find differences, that it's slightly quieter now as well but that may well just be down to the lack of drone at those lower rev points.

It's certainly more civilised around town from inside the car but still sounds just as loud outside according to my mate who did the drive-by vids for me.

Overall, I'm very happy with it!

13th July 2014 - Here's the pictures and videos from my new exhaust.

Raised the car and found that the rear left silencer had already been replaced and an Audi sleeve used.



Using that pre-existing cut we copied it on the right pipe and removed both silencers



We then made up a straight through pipe with quad tips (the ovals the garage had were tiny) and these were joined using sleeves so that I can quickly/easily swap them over to the stock silencers when/if's needs be.



After leaving off the brace bar I found that one really was needed as the tips pushed out and melted the outsides of the plastic oval area so we the added the brace bar back on to finish the job.





Here's the videos -

manmaths - Audi had the idea as the stock exhaust has a brace bar to keep the tips from moving outwards, the change in exhaust note on mine is just a very welcome coincidence.

27th July 2014 - Myself and a bunch of fellow Audi petrolheads all met up for a quick blast or 4 through the Hindhead Tunnel before heading off to MB World to watch the Hungarian F1 GP!

Hindhead Video - RS6, 2x RS4 and Nissan GTR doing 4 runs through the tunnel. That GTR is ridiculously loud! - http://www.youtube.com/watch?v=EUZY3wMzp9U

1st August 2014 - Had a 10,000 mile service done at MRC as the mileage passed 80k a few weeks ago. Got a nice clean bill of health with a lighter wallet although Ben "somehow" managed to talk me into Wagner Intercoolers in the near future, the silver tongued devil biggrin

9th August 2014 - Took part in the "On Your Marks" charity day run by ASDA by giving passenger rides for donations at the Rally For Heroes gate.

The weather was stunning (I'm now a nice shade of lobster) and the entertainment was phenomenal considering the whole event (10,000 people) is invite only.

I had an absolute blast and our gate alone (20 cars) raised over £2200 and there was 300+ cars doing rides so the final total should be epic.

Sadly my day came to a slightly abrupt end when a boost pipe spilt leaving me Turbo-less frown but the awesome driving I managed to get in before it went wrong more than made up for it. Everyone seemed to enjoy it hugely as these reaction videos show, although in the 3rd clip I managed a 4-wheel drift over the chicane rather than around it much to the amusement of the passenger biggrin

The Reactions Video is here - http://youtu.be/jirlMHJBbdE

Slightly random, but from your location and the noise of the GTR, is it quite tweaked and has a plate fitting to its model? If so, it does sound awesome and is incredibly quick!
It's running 650hp ( SVM Stage 4.25) but I've no idea what the plate was sorry

15th August 2014 - After my issues at the ASDA charity day last week I finally got the undertray off and found that the the drivers side lower hose had slipped it's jubilee clip off which caused the boost leak rather than a split hose. I managed to get the bugger back on (damn you Audi with your way too short hoses) and took it to MRC today to have the uprated Wagner intercoolers and silicone hoses fitted.

From the feel on the drive home and the oil stains on my old intercoolers I'd say mine had been leaking a while. With the RS being so quick it's sometimes difficult to notice when the powers a little down but the difference pre/post wagners is definitely noticeable. On a 300m stretch of the airfield I work at I'm now getting an extra 10mph over my last run on it this morning, so I'd say I've regained what ever power the leaking I/C's had cost me previously.
