What have you done to your car today?

After doing my thermostat housing, I had a few days of no water on the under shield.
Then I noticed another leak, this time it was the radiator.
So I fitted a new one yesterday. (Top photo)

The old rad still fine, until I removed it.

The side you see in the car, looked in good condition, the other side, which is against the AC rad, was in a terrible state.

Laid out all of the parts to rebuild the rear end + front strut assembly, ready to split them into the parts needed for each section of the car/job. (Just waiting on a couple of parts from LLLparts and my Eibach springs are still in the garage loft, but otherwise that's all of it!)

Looks like a lot of work. :)
 
Got the rear diff oil and gearbox oil replaced on my 3.0si today in prep for my first trackday in it. Not sure if its a placebo, the UK heat or if it is actually the change but gearshifts definitely feel smoother, less like there is interference. Will see when I drive the car from cold.
 
Nothing exciting today. Changed the passenger side halogen halo bulb. Was a 5 minute job with the genuine bulb from BMW.

Cleaned inside and outside of the Access flap too. Now I have to remove and do the rest of the liner 😂

Steering Lock inward.
Jack up.
Twist lock the flap off with a coin.
Unspring the clip (used the socket extension bar for leverage),
pull the rear of the light cover towards the wheel,
then slide it out of the arch as it has a tab towards the centre grill,
twist the bulb holder 1/8 turn counter clockwise,
Pull it out,
disconnect the cable.

Then reverse to put it back together.

Really simple. Seems to me people are massively over complicating it!

Did you go with the BMW high friction diff fluid?
 
First time the Z4 has let me down. I’ve done a good amount of preventative maintenance recently for my Nurburgring trip.

I had a minor breakdown on the A303 on the way to the Ring. Suddenly very bad misfiring, no warning lights.

I think one of the coil packs failed. Couldn’t seem to correct it by reseating the coils.
 
Got my favourite cleaning product of all time. Second to a retrim, nothing better out there. Top half of steering wheel done, I use a jay cloth to protect everything else from over spray of the cleaner. Then use an LRC soft brush to rub it into the leather, followed by wiping off with a Terry towel. I have the cream protectant to go of later from LRC too.

Seeing as the old girl is transporting me, my lad and all our camping gear to Le Mans again next weekend, for the anniversary of our first trip in 2006, I thought I'd better replace the leaking nearside engine mount.
Backed the car out of the garage onto the driveway and 90 minutes later the job was done and two new Meyle engine mounts are keeping the engine where it should be

Fitted a 3d printed drinks holder it's actually pretty cool! And some netting for the boot to stop s**t falling about, oh and a sexy new cherry air freshener for California scents lol

Then lots of wax and cleaning as usual because being OCD with my car is a way of life 😎
 
Fitted another Chinese made stop / brake light in the boot.
The last one I bought (also made in China) has lasted seven years until a work colleague pointed out to me yesterday morning that not all the LEDs were lighting up.
That one cost £26 in 2019. This new one cost me £15 from UK based upgradeautoparts and it arrived in less than 24 hours after I ordered it on ebay.
 
Cleaned throttle body and ICV (and the engine bay along the way). They weren't that bad but the ICV would get stuck occasionaly when shaking it.
I already noticed some improved engine smoothness.

First time I’ve lifted and got underneath it today!!

On the outside: engine flush and oil+filter change, top up of coolant, and identified leaking oil pan gasket, I think. On the inside had a play with coding and now have a triple blinking indicator and a double flash when I unlock! Also confirmed my suspicion that my headlight washers are coded “off” - they are and they have stayed that way 💪.

Then went out for a blast of course.

I hope your oil leak is the usual cam-cover or oil filter housing gasket, as I think you need to remove the cross-member to get the oil pan off.

Coding is handy, mine has the 3 flash indicators and beep on lock set as I'm never quite sure if I saw the indicators. :rolleyes:

Good news about the headlight washers too. All they do is put streaks up the wings and lose the caps, until they start leaking and the lack of fluid means the screen-washers don't work either. :headbang:
 
I tried to set the alarm chirp on lock but it didn’t play ball - for the exact same reason as you!

Then started to get the self-imposed nag of “drive the bloody thing stop pissing about with it” 😂

Definitely seemed quite a bit “fresher” oil round the pan gasket.. top half of the motor is pretty clean 🥲
 
I suppose the triple flash on locking might mean you're more likely to notice it.

My 330i has the same N52 engine and has had the top gaskets replaced, but so long as it only getting an advisory for "oil leak, but not excessive" I figure it's cheaper to just top it up with half a litre every 2,000 miles or so than pay for a sump gasket to be replaced!
