Cool Stuff Gav, I don't see many of these M3's in this condition running around. Hope she's looking after you!
I'm sure once my baby's had heart surgery, I'll bring her to you for cosmetics :cool:

Oh! Forgot to add another important update.

In January, Danny brought his car to me for a freshening up, and in exchange, he rendered some IT skills on my car. Something I was on the fence of doing ever since I got the car - the GTS flash for the gearbox.

After connecting to the car, and checking file versions, it turns out that while the DME software was the latest and greatest, the DCT software was one of the earlier versions. A few minutes later, and things were ready to rock and roll, and anxiety levels were a little bit elevated.

Overall, it took around 5-10mins to flash, and I'm pleased to report there were no issues. Oddly though, I didn't go for a test drive after the flash, but rather moved the car in and out the garage a couple of times. The forthcoming days would tell....

Feedback:
I've waited a while to provide feedback, as I wanted to clock a good few kms first to see how things go and whether the car needs to adapt at all. The fact that I do minimal mileage anyway means it takes longer still. Since the flash, I've only covered about 250kms in the car.

On startup, there is nothing different to note. Selecting D seems the same as before, and the car moves off without issue. Selecting Reverse does seem faster and less clunky, which is in line with overseas reviews.

When driving, the car is still in D2 by default, and the shifts are nice and smooth. Honestly, I can't really say that there is a significant decrease in shift time, but that may be also due to me pottering around the suburbs for the most part. There have been a few occasions to stretch the legs a bit in the lower gears, and the gearbox goes about it's business without fuss. It would have probably also helped if I drove the car back-to-back before and after the flash, but at the time that was not feasible. Anyway. All good so far.

One thing I can comment on is the weird jerk that the gearbox does just before changing up (noticeable from 1st to 2nd and 2nd to 3rd). I've commented on this previously and likened it to when you dip the clutch in a manual car. That is significantly improved now with the GTS flash. It is still there, but hardly noticeable, and less jerky in low speed driving. Overall this makes it much more pleasant to drive now. This is the single biggest stand out benefit for me at this point in time.

Others have also commented on the jerkiness when slowing down to a stop. I suspect this is improved too, as I haven't noticed that. Thinking back, I did experience some of this clunkiness, but not as frequently as others I believe.

Overall, it seems like this was a worthwhile update. The car is more pleasant at low speed driving (as long as the temp sensor and O2 sensor faults stay away!). Mildly spirited driving is still quite exciting. I have yet to drive the car in full attack mode, so will comment on that at a later stage.

That's all for now. Thanks again to Danny for the help and technical assistance on a regular basis.

Update May-2021:

A couple of small updates over the past month or two:

One one of the wash weekends, I decided to whip out a new drying towel to try out, this is the "Dry Me A River" from The Rag Company. Feedback is that it works very well. It's a decent size without being obnoxiously big, so it dried off the car without much effort. It is also a bit easier to handle when it starts to get a bit wet, and after rinsing it with clean water, it is fairly easy to ring out, when compared to the heavier GSM drying towels available. Overall I am happy with this product, and I now have 2 proper drying towels in my personal collection.

At some point during April, I also had to prepare for some home repairs, which required the purchase of a few lengths of PVC gutter. So the M3 obliged to it's duties of contractor's workhorse. I fitted the roof racks, and went to collect my materials. This actually worked out great, and is more practical for long items than it would be using the Ute. There were some raised eyebrows in the parking lot during loading, lol.

Then, more recently, my kids have enjoyed going in the car lately as they take a keen interest to watch on the Nav screen where all we are going, what the different roads look like and so on. The only issue was, that the maps loaded on the car are 13 years old (2008 edition), so there are many areas around us, and throughout Gauteng where development has taken place, but on the maps it just shows that we're driving through a green field.

I spoke to Danny from DSC Motorsport, and a couple of days later, we were ready to flash the maps to the latest 2020 Premium Maps for Southern Africa.

The process is fairly straight forward (after a few practice attempts:
  • Put car on charger to ensure enough constant voltage can be supplied
  • Insert flash drive with maps and config file into the port just behind the glovebox.
  • Ignition on
  • Naviation function on iDrive
  • Wait for the update to be detected, start update
  • Enter FSC code (essentially a pin to allow the maps to be loaded)
  • Wait a bit (I think it took about 10-15mins).
  • Reboot and verify update completed successfully.
Some pics of the steps below:

Even with the charger connected, the car was complaining about low battery (I think I'll need to replace the battery at some stage in the next 12months).

After the update, the maps have a slightly different (refreshed?) look to them, and from some initial tests, it seems to show some of the newer areas. That being said, I haven't driven the car out of our suburb since the update, so will do a proper test on a longer trip again at some point.

That's all for now....

Lovely......I also like updated maps and even though my phone has the best maps (updated), I still prefer to use the car maps for some reason

Sorry for the delayed response. Haven’t used the car for the past month.

If you’re interested, you can PM me and we can discuss the maps update. Otherwise as mentioned in my post, Danny2 does it.

Here’s some pics of the graphics:

Reading this build thread made me happy.

The clinical look just works on Alpine White E9X M3's. Personally, I would de badge the rear to finish the look but what you've done so far is nothing short of phenomenal.

Update Sep-21 to Oct-21:

My eager eyes on overseas forums, together with some impulsive online shopping, led to 3 boxes arriving at my door the past few months. Some updates for now, and some for later on.

For this update, something I have been hunting for ever since I got the car 2.5 years ago. Some genuine Akrapovic Evolution Titanium Tips. These were actually part of a full slip-on system. The rest of the exhaust was sold to a forum member in California, so I ended up only shipping the tips to South Africa.

Overall they were in good condition, and my mate in the States did give them a wipe before shipping:

I wanted to make them look brand new again, so got busy with some degreaser and Cleen Green to remove any muck still left on the tips. Titanium is also sensitive to certain cleaning materials, so I wasn’t planning on anything too aggressive which could compromise the finish. I used Brasso, and after a couple of hours, they were looking great:

I couldn’t resist, so did a test fit on one side of the car in the evening. I am glad I got these, as IMO, the rear of the car always looked ‘dirty’ with the CF tips, it almost looked too aftermarket. The titanium tips are, dare I say it, closer in appearance to the stock stainless steel tips, same same, but different.

With half the tips test fitted, I decided to tackle the next thing which has also been an annoyance for me on the back of the car – that being the oversized black M3 badge. To the best of my knowledge, this badge comes from the F80, and is much bigger than the stock badge. Also, from what I could tell, it was installed with incorrect spacing and alignment. Anyways, it had to come off…

Bye bye….

The next morning, I finished installing the tips and cleaning up the bootlid after the badge removal. I’m much happier with the rear end of the car now. I’m still in 2 minds whether a badge will go back on, time will tell.

I also cleaned up the CF tips before shipping them off back to the States for a buyer up near NYC:

The last little update, was that with the onset of summer, the A/C was not working too effectively. I made contact with someone we've used before, who has the correct machine to vacuum the complete aircon system, and then replace with the correct amount of compressor oil and gas as per the spec of the car / system.

To regas this car proved a bit of a mission, as the one valve sits under the cowl of the windscreen wipers. This necessitated removing the airbox lid and disassembling half of the cowl, to get to the valve safely.

The regas was successful, it was low on gas overall, so glad that this is done, so that I don't slow roast in the summer heat.

More updates coming soon before the end of the year if all goes well :)
