Can a 200,000 km F30 320d Still Be a Good Buy?

I haven't done the EGR delete as yet. I haven't actually done any performance mods to the car as yet. Only creature comforts like the apple car play, sports gear shifter, paddle shift steering wheel retrofit and the digital climate control cluster replacement (That was a pain to code but works beautifully) and the E89 msport 19" Rims and headlight cover replacement, but in terms of performance stuff, stock as it came from the factory.

With regards to the sports shifter, yea I don't think it does anything differently but I did set the cars transmission to the sports transmission in ProTools when I installed it which made a big difference. From how it was to how it is now it almost feels like I put an XHP flash on the car.

I do definitely also need to do suspension next though.
Okay cool man, I also enabled Sport Auto Trans when I coded the Start/Stop memory and I agree with you, It makes a massive difference in the shifts. That coupled with the transmission service and EGS Adaptations really transformed the way my car selects and changes gears now. It’s chalk and cheese.

THIS WEEK’S UPDATE - STEERING WHEEL, ANDROID SCREEN & COOLING SYSTEM PREP

First up, the steering wheel. This one was long overdue.

The steering wheel is probably the one part of the car you’re constantly interacting with whenever you drive, so fitting a fresh one always makes the whole driving experience feel that little bit better.


The MQS terminals and wire finally arrived, so I made up the missing paddle signal wire and ran it from the FEM to the steering column.

The old steering wheel was removed and the new M Sport wheel with paddles fitted.3.jpeg

I also added the harness for the M1/M2 buttons, which allows me to cycle through the driving modes from the steering wheel, and connected that into the iDrive controller circuit.


5.jpeg


Once everything was wired up, I coded the car to enable the paddle shifters.
Tested everything afterwards and I’m happy to report that it all works exactly as intended.


Paddles are working, the M1/M2 buttons are changing the driving modes, and the new wheel has made the interior feel much fresher.

Next up was something I’ve been waiting a while for.
I recently ordered a full aluminium oil filter housing from the US. I specifically wanted this particular version because it is properly aluminium throughout, rather than some of the versions I’ve seen being sold locally which use an aluminium outer housing but retain a plastic centre thermostat section which I've noticed always fails around the brass thermostat valve when the plastic cracks as shown in the pics below from another N47 we worked on recently.

While I was ordering, I also added:

  • Aluminium coolant flange
  • EGR delete kit
  • Swirl flap delete kit

Then, while browsing through the cooling-system parts, I made the mistake of seeing a 12.3-inch Android screen for the F30. šŸ˜‚
It looked really good, so naturally I ordered that too.7.jpeg


What I didn’t consider was that the dashboards on LHD and RHD F30s are different.

The advert didn’t mention anything about LHD or RHD compatibility, and I’m assuming that’s because it was being sold primarily into a left-hand-drive market.


Needless to say, I discovered this the hard way...

At around 21:30… About 50% of the way through the installation. šŸ˜‚

Since I was already that far into it, there was no chance I was putting everything back together.

So I modified the mounting panel and made it work for now.

It’s not the final solution, though. I’ve already asked a friend to check for the correct RHD version when he goes to China at the end of the month.

If he can’t find one, I’ll order a RHD housing from another version and modify the two pieces to make one that fits and looks the way it’s supposed to. For now, though, I’m just happy to have Waze and my music working nicely on the larger screen. I still need to run and wire the reverse camera, but I’ll get to that soon.

Now onto the next major job…
At this point, pretty much every fluid in the car has been switched over to its Motul equivalent, with the exception of the engine coolant. That’s next.

I now have everything required for a fairly comprehensive cooling-system refresh:

  • Motul coolant
  • New thermostat
  • New thermostat housing
  • Aluminium coolant flange
  • Full aluminium oil filter housing with Thermostat assembly, Both oil coolers, New cooler gaskets and seals

I’m not replacing the water pump because BMW replaced it last year, along with the coolant expansion tank and cap, so there’s no point replacing perfectly good recent parts just for the sake of it.

This cooling-system job looks like it could easily turn into a two-day affair if I want to do everything properly, clean everything up while I’m there and make sure there are no leaks afterwards.


So when I get another decent gap in my schedule, that will be the next big job.

Still making progress whenever I get the chance but looks like there there isn't much else left to do after this besides rack up mileage and enjoy it.

THIS WEEK’S UPDATE - COOLING SYSTEM REFRESH, OIL FILTER HOUSING, INTAKE & EGR WORK

We had some time Yesterday so the 320d went back onto the lift for another fairly big round of work.

1.jpeg
2.jpeg
3.0.jpeg
3.1.jpeg

The Coolant Drained and engine bay was stripped back to get access to all the cooling-system components I had been collecting over the last few weeks.
4.0.jpeg

While everything was opened up, I also took the opportunity to have a look at the turbo. Happy to report that it’s looking good for the mileage. There is very little shaft play and the compressor blades look clean and in good condition.
4.1.jpeg

First up was the thermostat and thermostat housing.
I had suspected there may have been a coolant leak in this area previously because there was quite a bit of dried coolant residue around the housing where the hose connects. Once everything was stripped out, it confirmed that replacing these parts was definitely worthwhile.
5.jpeg
6.jpeg
7.jpeg

A new thermostat and thermostat housing were fitted.
8.jpeg

Next was the intake manifold removal as well as the coolant flange and complete oil filter housing assembly. This is where things got interesting.

I’m very glad I decided to replace the oil filter housing Preventatively rather than simply leave the original one in place.

Once removed, we found that part of the original housing had actually failed internally. The small brass valve had broken off and was lying loose inside the coolant channel on the engine block. In the pictures you can clearly see the broken brass piece and where it had separated from the original housing.
10.jpeg

12.jpeg
13.jpeg

Then compare that to the new full-aluminium housing.
14.jpeg
9.jpeg

The original plastic unit also has quite a few recessed areas and weak points in its construction, while the new aluminium version feels much more substantial and eliminates a lot of the plastic components that tend to become brittle with age and heat cycles.
15.jpeg16.0.jpeg

Once the block mating surfaces were properly cleaned, the new complete aluminium oil filter housing assembly was installed together with the aluminium coolant flange.
16.1.jpeg
16.2.jpeg


Hopefully that’s a few more plastic cooling-system weak points removed from the equation.


Then came the intake manifold. This was probably the biggest surprise of the whole job. The moment the manifold came off, I was expecting to find the usual diesel carbon build-up through the intake system and cylinder-head ports. Instead, there was almost nothing.17.jpeg18.jpeg
19.jpeg


The intake runners were incredibly clean, the ports in the cylinder head had virtually no carbon build-up, and you could clearly see down towards the valves.
20.jpeg
21.jpeg
22.jpeg

Honestly, I was expecting something completely different from a 200,000 km N47.
What a car this is turning out to be. Lebofa clearly looked after this engine properly over the years.

Next up was the EGR system.
The EGR cooler was removed and, surprisingly, even the cooler core had very little carbon build-up inside it.
23.01.jpeg
23.1.jpeg
23.2.jpeg

The EGR blanking plates were then fitted while everything was accessible.23.0.jpeg
26.0.jpeg25.jpeg
26.1.jpeg


Back to the intake manifold…
The original intake gasket plate also houses the swirl flaps, so I initially removed the flaps from the existing plate while waiting for the replacement gasket plate to arrive.
While the manifold was off the car, I also gave the outside of it a proper clean because it had accumulated quite a bit of dirt over the years.
28.jpeg29.jpeg
30.jpeg

Since we ended up waiting for the manifold gasket plate, we moved onto refill the cooling system.

34.jpeg

Before adding coolant, I vacuum-tested the system to make sure it could hold vacuum and that we hadn’t introduced any leaks during the work. Everything checked out, so the system was vacuum-filled with Motul Auto Cool Expert
coolant.

35.1.jpeg35.2.jpeg

Once the new gasket plate arrived, it was fitted with the swirl-flap arrangement removed, and the intake manifold was then reinstalled onto the engine. New on the bottom. I had used the old as test to remove the flaps.

31.jpeg
32.jpeg

The battery was reconnected, the engine started, and both the coolant and engine-oil levels were checked.

36.jpeg
37.jpeg

With everything mechanically back together, Everything looked good. No visible leaks, no coolant loss and everything was operating as expected. By that point it was getting fairly late, so I stopped for the evening and left a large clean sheet of paper underneath the engine overnight.

The following morning, the sheet was still completely clean.
No coolant.
No oil.
No leaks.

Started the car again, no warning lights on the dash, and took it for a short test drive. I’ve only done about 5 km since completing the work, but so far everything is running perfectly. The engine feels very smooth and responsive. Whether that’s actually related to the intake changes or simply everything being freshly reassembled and serviced is difficult to say after such a short drive, but the car definitely feels good.


No engine warning light has appeared so far either, but I’ll continue monitoring everything as I put some more mileage onto it. Overall, I’m very happy with how this round of work went. The biggest surprise was definitely seeing just how clean the intake system, cylinder-head ports and EGR cooler were after more than 200,000 km.

It’s becoming more and more obvious that this Vehicle has had a very good life.

And lastly, an interior picture since I don’t think I’ve posted many of those. The inside of the car is also in really good condition for its age and mileage, especially after the recent detail. 38.jpeg


That’s it for now.

That carbon free intake system is unbelievable at that mileage!
What a healthy unit she is 😁

Coming along nicely
