Looks like I'm not the only one who can rock the respray. Looks damn good to me.Well I think you’ve done that before haven’t you!! Don’t tell me that’s from a rattle can??

No not the first time doing something like this, I have done a door before, but yes all done with spray cans, I figured that the arch looked so bad I didn't have much to loose. I think that the Ebony Black Pearl colour is quite forgiving as it doesn't seem to fade much even after 18 years. The picture is also after wet sanding with 2000 grit and polishing.Well I think you’ve done that before haven’t you!! Don’t tell me that’s from a rattle can??
Where did you source the 3L parts and have you noticed a difference?With lockdown continuing and boredom setting in and rather than spending my evenings sitting at the same desk at home that I had spent all day at doing work at but playing computer games instead it was time for more garage project work on the A2 this time focussing on fuel economy. For this I added the underbody spoiler from the 3l as well as the winglets and fabricated replacement heat shields to go around the fuel filter. I also created a blanking plate for the front grille and swapped out the thermostat as I think the one in the car was a bit unhappy.
Lower grille blocking for fuel economy gains
Engineer's note on grille blanking: adiabatic cooling effect should not be discounted i.e. a narrow slit in a high pressure area, allowing air through which then is forced to expand, thereby lowing its temperature. Done well, you can have the aerodynamic benefits without compromising the cooling...www.a2oc.net
I got the 3L aero parts from Crewe Audi as new parts. I'm not sure if they have made a difference because I have had very limited experience of the economy before. I know that I can get very good economy out of it now though without a remap or any modifications to the gearbox.Where did you source the 3L parts and have you noticed a difference?
Sorry, yes it was a good walk and am happy to report that the seats are much comfier than the ones they replaced now that they have had a few thousand miles of being sat inLooking good. Hopefully you had a nice walk on the Pembrokeshire Coastal path after your visit?
Nice to meet you and nice car you have there.
So just over 5 weeks in with the DEFA heater and I have done plenty of driving in cold, snow and heavy rain and I think the heater is making a difference. Over the 2,000 miles I have done in this time I have used the heater for approximately half of the starts (i.e. each morning leaving for work) I have averaged 75 mpg (odometer distance between fill ups and fuel used, not the DIS value). Within this there was one week of driving where I had to use the webasto and this gave me a tank average of 68mpg vs the 75-80mpg the other weeks.
Yes otherwise on my journey it was taking close on 20 miles to get up to operating temperature without the climate on. My journey is particularly economical though as it is practically flat and very constant 45 to 50 mph. People at my work don't believe how little I spend on diesel per week.That's fantastic - I've been thinking that I'm doing well still getting 68/69mpg at this time of year. Using my Defa heater in the mornings, mine gets up to temperature about 5 miles sooner than if I don't.
Yeah I am slightly apprehensive about that part but I figured that it is not super different to what the lower gears would be like if I had gone for a JDD/MZN which was the other option I was weighing up. The main decider for the PTW was the considerably lower purchase cost (compared with MYP, I think MYP are expensive because these are a favoured gearbox swap for VW Caddy’s) and it being available locallyOoh a PTW. Good choice.
I would be interested to learn what it drives like with the very high intermediate gears without the benefits of the variable vane turbo the 90 model comes equipped with.
As a fellow Tdi75 (albeit BHC) owner with a PTW and a Defa heater installed, I will also be interested to see the numbers. I finally was able to undertake the planned long distance runs with the PTW 6th from Scotland to Plymouth on two return trips this last summer, and superficially I didn't see any notable difference in economy despite running a significant proportion of the motorway miles in the markedly higher 6th around 800rpm less than I was doing on the previous runs.Yeah I am slightly apprehensive about that part but I figured that it is not super different to what the lower gears would be like if I had gone for a JDD/MZN which was the other option I was weighing up.

Currently I do a lot of lower speed driving in the tallest possible gear so am fairly confident in the performance of the AMF at around 1400 rpm.
I also saw this post by robin cox where it’s been done before and that gave me some confidence that this is a viable option for the AMF.
Thanks Robin for this comprehensive overview and it’s giving me additional confidence in my choice. That does in fact sound very worthwhile. I’m running 185/60 R15 tyres which means that my mileage counter is essentially accurate. For sure I will keep this thread updated once everything is all installed.As a fellow Tdi75 (albeit BHC) owner with a PTW and a Defa heater installed, I will also be interested to see the numbers.

However : it is worth noting that the journey at 2150rpm was a lot more pleasant than 2900-3000rpm for the long constant speed sections (~350 miles from roughly Lockerbie to Taunton). I was going through my fuel stop receipts and recorded mileages a few months back and realised that I might have been discounting a tyre diameter component using my 195/55/16 Rainsport 3s to the tune of about 55 miles (using odometer) over what I know to be 545mi door to door (genuine 545 mile distance confirmed by multiple accurate resources) in my Fuelly calculations with the new gearbox. This would suggest about a 10% improvement in mpg over what I had calculated based on the numbers I had to hand on the journeys down and back with the new box, so perhaps my initial impressions from an expenditure perspective were impaired due to gearing and tyre diameter issues not being accounted for. In this instance then the PTW may actually have given me a 10% improvement that I hadn't noticed previously owing to not noticing the smaller recorded mileages instead of using the map distances for these in Fuelly.
Yet to use the Defa, conditions where this will be useful are approaching.
