Today, I gave my new Fsi it's first wash.
Jet rinse, snow foam soak, jet rinse, 2 bucket wash, rinse and dry, fall out iron remover on wheels and lower body, rinse, and another 2 bucket wash.
Next, it will get a full body clay bar paint decontamination, 2 stage wash, and then a compound, seal and 2 coats of a suitable wax.
Yeah, I like to clean cars
.Also, fixed the wiper park so now it's at the bottom of the screen.
All from 3.30 to 6.30 this afternoon.
Once it's had a proper detail, and an oil, filter, and brake service, I'll post up pictures in it's own thread.

Diagnosed a slow rotating radiator fan.
Did the climate output test, no difference in fan rpms between speed 1 and 2.
Measured signals on the 6pin connector, 3 pins populated, 1: alternator charging signal - ok, 3 / 5: ground from the climate control module (speed 1 / 2) - ok.
Connected the fan directly to 12v and it rotated full speed.
Bye bye radiator fan control module

Fitted some rubber car mats:
They are quite industrial but fit well. I'm about to teach my son to drive so wanted some non slip mats.
Aftermarket carpet mats joining the original Audi in the attic.

Not sure I understand your radiator fan issue.
When the climate is turned on the radiator fan rotates at a slow speed to ensure air flow over the condenser.
When the engine heats up the fan still does not increase above the slow rotation the climate has requested ( or if the climate is off the fan is not rotating)
As the engine gets too hot ( not sure now of the actual temperatures ) speed 2 is commanded to the fan which now rotates at the medium speed.
If the engine continues to get even hotter then the third rapid speed is commanded.
In operation I think only twice has my fan ever switched to the medium speed and even then it very quickly dropped back to the slow climate speed.

@PlasticMac Thanks for the suggestion, I connected the fan to the FCM supply to test both the fan and the supply.
@audifan Correct, the fan rotates at high speed rarely, but in this case I started the climate output test which tests the fan as well, low and high speed.
There are 2 speeds only, which are activated by the climate control or thermo switches.
As I use obdeleven bluetooth / mobile app I started the climate output test while observing the fan and saw that there was no difference between low and high speed.

WOM can do all of your engine and mechanical work. You can ask them about gearboxes.
I travel to them in Stafford from Aberdeen but it would be a bit further for you.
Would someone tag Rob on this please

@chumsofmanutd is the man to PM. It’s Robs business with his brother Marcus.
All of my experience with them has been superb. Quality of work and coms excellent and nothing you’ve indicated you want doing would strike me as being beyond there expertise.
I should also add that I only came across them due to the many other members who recommended them!

Today on my wife's Tdi I:
- Replaced the tandem pump and gasket
- Removed the EGR, cleaned it up and put back with new gaskets
- Replaced the rocker cover with the later type and reinstalled with new bolts and gasket
- Did the oil and filter, and replaced the air filter
- Replaced the thermostat and put in new coolant
- Found the cause of the ticking sound under load - as I suspected, inner CV joint has gone thanks to a separated boot, will do this once I have the parts

Last night I did the now-familiar 145 miles from Axminster to Maidenhead. A highly relaxed 65mph all the way listening to the moneybox podcast series and generally enjoying the alone-time (father of 3 young children, such time is appreciated!).
I rolled into a fuel station at this end with 15 miles range showing on the CDIS and a new tank record of 691 miles - Happy in the knowledge it would have done the target 700! - This is - as always - on a full tank (burp toggle always used to fill to the neck) of supermarket diesel with the Millers diesel additive added. Journey consumption was 69mpg and as car then took 45.5 litres, a quick calc reveals this is the tank average too which is up there with my personal best: I've done lots of long relaxed journeys at sub-70mph cruising speed, where this car shines.
When the car next goes in the garage I'm looking forward to addressing the slightly dragging handbrake on the driver's side (now corrected with a hammer tap on the mechanism and the armrest permanently down to discourage use of the lever until it's sorted) and putting on the straight-through inlet pipe and seeing what both of these does to the figures, hopefully 700 miles to a tank becomes slightly more common, especially when the weather warms up properly - Who says TDI90s are comparatively thirsty! I wonder what a six speed TDI75 would do under the exact same conditions however.
As an aside, I've been using Calix engine heater more and more recently - and even just 90 minutes with this plugged in starts the engine off at 50 degrees and it gradually warms up from there. I say this not because it I think it makes a major difference to consumption (it would on short journeys though), but because of all the recent talk of slow / incomplete diesel warm-up: I thought the coolant temp would bleed off because the oil is cold, but this appears not to happen, interestingly.

Are you're talking about the Cobalt TDI that I used to own? If so, I'm glad to see it receiving plenty of attention and new parts. It always revved very freely, I suspected the EGR had been machined out, did that turn out not to actually be the case? I'm surprised it needed a thermostat though. I had that done at WOM in 2019 so it would have been OEM or at least equivalent quality. Should you only expect them to last 4 or 5 years these days?
I ask because I'm not completely sure about the 'stat on my Crystal TDI, that I last had done in 2018. Although the temp gauge stays at 90 once it gets there, to get there in the first place it can take 10 miles even with the Webasto going - and the last 5 of those miles at 60mph. It's now getting to that time of year when the mornings are no longer quite cold enough to bring the Webasto in, and on those days it can take 15 miles to get fully warm. If the last mile of that wasn't a 50mph incline, I'm sure it would take longer.
With the amount of posts about the TDI thermostat it should have its own forum!!!!
A suggestion for TDI owners. It seems clear to me there should be some definitive data for coolant warmup. If several TDI owners with healthy thermostats logged with VCDS say the first 20 minutes at say 0℃, 10℃ & 20℃ over the seasons, with brief description of the journey, then the logs can be can summarised by a simple graphs with Excel. With a few graphs posted in various scenarios a definitive bank of results can be made, ready for comparison by the TDI owner who is questioning their own thermostats.

Those of us running CDIS can do this without plugging VCDS in - I have a journey later from parents' in Maidenhead to Epping in Essex so I will do this and report back- I may do 5, 10, then 15 minutes. I know my thermostat is working correctly and this journey is 3-4 miles back roads and then all motorway - and all on the flat; unlike when I'm home where I have to ascend a steep hill only a couple of hundred yards from my house - so it will be a good baseline.
I'll post the results in it's own thread for others to compare to.
I am! It's doing a great job of being the family daily driver at present while my A2 is still being worked on. Once I have my car back on the road it'll still be doing my wife's commute, but it'll only do 250 miles a week, not 600+...
I think the EGR is standard, I couldn't see any signs of machining. The main bit wasn't as bad as I feared it might be, but it did look like the valve wasn't seating right. Gave it a good clean and it looked much better. Previously I found it was bogging down a lot until warm, where as this morning it felt much improved on the usual run.
I thought the thermostat might also be an issue as it took quite a while to get to temperature and once there it'd apparently lose it very quickly whilst parked (eg. could go down 50% in 10 minutes), which my car doesn't do. There was some crud on the thermostat that came out and it definitely warmed up quicker this morning. I know the car was sat for quite a while before I got it and suspect this is the cause - same thing happened on my MINI just from lack of use. I'll see how it goes but may replace the temp sensor later in the summer.
Next job, apart from the CV joint, is alloy wheel refurb - any recommendations welcome!
Today I / We did something different drove over to near my home town of Chorley Lancashire and took a walk onto the West Pennine moors, on a clear day you can see over to Manchester, Bolton then around to Liverpool, North Wales, Southport, the Ribble estuary, Fylde coast (Lytham & Blackpool) then on North to Grange, Barrow in Furnace and the Lakes plus all the other area Inbetween.
Sometimes it's just good to get away, a nice 6 mile walk in the fresh air and spring bird song.

Today as part of replacing my driver’s headlamp I changed my high beam bulbs for a set of Osram +150% Nightbreakers - which are the best available upgrade for the high beam’s H3 size.
Pleasantly surprised by how much brighter and whiter the light output is - combined with the H7 Philips RacingVision +200% dipped beams my lights are genuinely decent enough for fast country road driving at night now - just need to adjust them upwards a couple of turns so I can adjust their dipped level to suit the situation (ie. Switch between separate carriageway mode - where I like them a little higher whilst still not dazzling other traffic; and “normal”).
I can highly recommend to you all to do exactly the same in terms of both bulbs and adjustment - just remember if you adjust your lights like I do to remember to adjust them down again when you should!
