Fingers crossed.

I was getting a strange vibration from the rear of mine on my short motorway commute. I realised that my new wheel cleaner had caused the wheel weights to fall off!

mines definitely not wheel weights lol


secretly i'm hoping it would be the suspension as I want to poly bush the thing and get it onto some coilovers…… then corner weight it and get the geo tweaked to my needs....


but I keep telling myself that for now she is still a daily....!!!

well I can happily say my vibration is gone, no more.... one is a happy one...!!!!



my inner cv joint was fubar'd

this time I didn't buy it from my main dealer....
Audi's price was £478.00+VAT
I found a brand new driveshaft in Germany that was 50.24 EUROS delivered to my door. It even has a 3 year warranty.
If it only lasts me 10,000miles it's still a risk worth taking, and certainly worth the risk to see if it eliminated the problem.

Ok, it's bare metal and not painted as nice as a genuine one, do I care? nope.... as my vibration is gone.....

3 days it took to get here from Germany. Shame the cruise control stalk I ordered from a shop in the UK couldn't be as good. Excuse after excuse as to why it's not been delivered and i'm still waiting 12 days later... I'll see if opening a case on Ebay will stick a rocket up the cock wombles ass to actually deliver what I've paid for.....

well finally my cruise control module stalk thingy turned up today... cock womble made good... why do some make it hard work?

What was nice surprise was it was a face lift set of stalks...
my first thought was "oh bugger will they actually fit and work?"
i'm not going to document the "how to change..." as there are enough of them about but other than the airbag connector being bloody tight to refit it all assembled perfectly.
I modified my cowl to fit, such is my OCD nature I want a proper cowl so am now on the hunt for one of them....

all fitted like a glove...

Plugged the computer in and cleared all the codes, recalibrated the steering wheel sensor and did the Steering wheel module and Engine module coding to accept Cruise Control and all done...!!!!

That's another job ticked off the list

well after a few failed attempts at finding a decent 2ndhand cowl for the cruise control retro fit... I thought i'd see what a new part cost....

£36,00.... I was amazed at how cheap this piece was..... ordered, fitted and another job signed off.....

I'm starting to get together a list of parts for doing a complete carbon clean, so it will involve taking the inlet off, whilst that is off I want to refinish the cam covers (I fancy the red as on the RS5).

and i'm itching to make a start on the exhaust, parts are also being accumulated…

I want to drain the gearbox and rear diff of fluids at some point and refill with something better, I've had good results with Redline MT-90 gear oils in the past, so need to see if that is still applicable.

so with the new driveshaft ordered, delivered and fitted and the vibration now firmly consigned to history it came as a huge surprise to have a knock at the door last week and a courier stood there with another box.... questions from the OH as to what i'd bought now came a blank from me...

Dragged the box in and low and behold i'd been sent another driveshaft... so now my 51 Euro driveshaft was even cheaper as I'd got two for the price of one...
So if the new one fails, it has a 3 year warranty and I have another to replace it with whilst I send this one back (if it fails) for replacement...!!!

Lovely car and like the work you're doing .
thank you... some aspects will take an age.... like the exhaust, as she is a daily i'll struggle to take her off the road and do in my leisure, which means i'll need all the parts to hand before strip down and then will need to be made in one hit.... long hard slog doing that as BTDT... some would say why not take the easy route and just buy one....!!!

if I did that I wouldn't have made it and it wouldn't be unique

but parts are being sorted and ordered... bought a gasket at the weekend so I could draw up in CAD the flange that bolts the CAT's to the manifolds, this has been ordered from the laser cutters....

all other pieces are sorted and I know what spec I want to make..... if you think i'm nuts raise your hands lol... but I do like making exhausts....

This was the manifold I made for my Fireblade

4 into 1 collector


slip joints

and then out the back end


plus many others over the years..... once done I can then remap and get the full benefit of it.....

small project to tick off, the subwoofer on the rear shelf distorts and cuts in and out, following the lead set by others I found this thread
https://www.a5oc.com/forums/audi-a5-s5-tech/94345-...
I won't repeat what's said there but I've gone for one of these
https://www.ebay.co.uk/itm/Pyle-PLPW10D-10-Inch-10...
ordered Sunday night and this turned up today

very quick service from the dealer....
and what's inside the box....



wasn't surprised to see a "Made in China" what isn't these days, looks well made...

onto fitting, rear shelf stripped out and new sub offered up, when placed in the opening from above the cage just catches the opening, so it will need fitting from below.
On the opening on the metal shelf there are 3 holes already, on the sub there are 8 mounting holes, so only one would actually line up. I am happy to redrill the metal shelf and i'll insert rivnuts so I can do all the fitting from within the boot.
The only downside to that is my rivnut gun is at work and i'm not.....

Stage 2 tomorrow night...….

lol thank you... i'd say more a miss spent youth and my people skills are abysmal..... but also been lucky throughout my career working in places which enabled my skills to be paid for and having facilities....

These days it takes a little longer and now senior management and spend most of my time behind a desk but I enjoy the excuse of getting my hands dirty...!!!

got home early to get to stage 2.....

sub fitted

I unravelled the wiring loom so I could wire up as per this diagram

I cut the plug off leaving enough of a tail "should" I ever need to go back to OEM

Yellow and blue went to the positive, white and yellow went to the negative and then I bridged the other +/- wire some audio speaker cable I had.

Interior all went back together without a hitch.


onto testing.....


(insert the biggest, smiliest smiley you can find here please)


I've always liked the factory B&O, having enjoyed it in my previous A5 and the same in my S5 but I can honestly say this is the first time I've ever felt the bass.....

time will tell how well this £30 (to be fair it was on offer and normally retailed at £55) "cheap" sub lasts but it's not the hardest of jobs to replace....

Well they do say once you go black you never go back.....

A chance purchase of a genuine S5 Black Edition grill made me a very happy boy. This for me was the much preferred route rather than painting the front grill as I know from experience that the paint never lasts long due to wear and tear...

So in between short showers today had the car sat in front of the garage awaiting surgery

as she left the factory, genuine chrome....

it just fell off honest Mister....!!!



love it...!!!

As said, my exhaust project is a slow burn project and it has to fit in around the real life stuff of work and actually using the S5 everyday but i'm happy to show bits and pieces along the way...
Things like the silencers will be bought items readily available, I'm going to use Magnaflow silencers as have used them a lot in the past with very good results.

Things like the flange to mate the downpipes to the exhaust manifold are not available, so are drawn up in CAD and sent as a file to the laser cutters to be made.

Starts like this

The parts arrived Friday and i'll stick a pic up of them when back in the office

All other joints will be V-bands, again it starts as a CAD file which is then sent off for machining. I prefer to make them as a male/female part as I've found they seal much better


and then the x-pipe, this starts as 4 individual 45 degree cut mandrel bends which are laser cut and then welded to form the X-pipe


So, it's getting there slowly.....

and here we have the 2no flanges laser cut from the CAD file


the only way these differ from anything standard is the centre bore is the diameter of the exhaust tubing I plan on making the exhaust from, this being 63.5mm diameter

ok, what's the next head scratcher then.... well I don't like the red illumination on the climate control panel.... I want it to match the white illumination on the dash....
thank fully others have already attempted this so having read up, then read some more and then read again... I've hatched a plan...!!!

It'll be a cold day in hell before I let an Audi "technician" plug anything into my car, so that ruled out any form of component protection removal, as I don't have the facility myself, as it can't (yet) be done via VCDS.

So a face lift climate panel has been sourced and my plan is to disassemble and modify my existing one using the LED's and white diffuser panel, thankfully I have PCB/LED soldering experience and the tools for it... Just hope the eyesight is up to it....!!!

FL panel should be here this week.... watch this space

i'm also tempted at some point to do the matching colours on the MMI panel as detailed on the AudiEnthusiast site but that won't be just yet

well as it's part of the VAG family I may as well post in my thread...

something a little bit different for the weekend???


under the skin it's basically a 6.0 W12 VW Phaeton, which makes getting parts cheaper than adding the Bentley tax

late 2003, with only 67,500 miles..... not been used in 3 years, more lights on the dash than Oxford Street at Christmas, tyres in good condition as at least it's been rolled back and forth and had a battery conditioner on it....
Interior was mouldy and had more penicillin than Boots the Chemist....

Main faults are it needs 2 new Bosch MAF's, hopefully that's cure the EGT and Lambda faults.... all lights turned off enough to get her MOT'd this morning and taxed so can at least drive the poor thing.

then this afternoon is deep cleanse time, more cobwebs than an Indiana Jones stage set.....!!!

finally the new climate panel arrived, so whipped the original one out for a comparison


initial observations are it is the correct FL version, in that the panel has the white on black display I am after.
time to take it to bits to see what's inside


I had hoped I could use the newer fascia panel and put the control buttons from my old panel into the newer panel... sadly they are not cross compatible, the clips which retain them are in different positions.
So my next thought was to take the chrome knobs and put them on the older panel.... nope different on the inside also....

so all i'll be able to swap over are the white LED's and diffuser and have my original panel but with the display I want.

My other option is to find a newer control panel with all of the buttons which match mine and go for Component Protection removal.....

Saturday will see me going blind looking at the TINY LED's and desoldering them and putting them into my original panel....

well what have we learned today.

the LED's on the facelift panel are a different polarity, with being a 4pin variety (strangely a similar aged S5 who had done the same mod his PCB and LED's were a 2pin type... no idea why mine are different but anyway).
You can rotate the 4 pin but it illuminates red as the originals are as it is reversed.

So 4pin white emitting LED's of the correct polarity are now on order.

Other observations are the white and red diffuser are subtly different, height and pin locations

1 step forward and all that...…
