What did you do to / for your E53 today??

[BigLion]

I get the feeling I should have done those power steering fluid pipes a long time ago - the steering is so much lighter for parking and more responsive at speed, I even let a couple of PSI out the tyres cos it felt a bit light - no rumble from the engine bay any more - can't wait to get a good run out! Headlamp covers will have ato wait for now

Installed E90 10W LED bulbs into E53 5w LED fitting (Both bought off ebay) then hardwired it to the ECU key position 2 wire through a fused Relay so that they become Driving lights and put resistors between the parking light wires so that I don't get the "Check park lights" message anymore.

Ahh the serenity

Finally removed the TCU/SOS and installed the ULF Bluetooth! I had a buddy at the dealer run through the programming. All that was needed was the new ULF and the pairing button for the center console. The mic, antenna, bracket, and antenna cable were in my kit from getbmwparts.com, but I didn't need them.

I have wanted this feature since before I even got my first 2004 X5 7 years ago! So cool!

Put in led SMD licence bulbs off eBay. So damn bright, and modern looking. Price is good too.

Bought these e53 bulbs and these e90 bulbs off ebay and placed everything from the e90 bulb into the e53 black plastic cradle so that it plugs straight in.



I used 400ohm power resistors and just cut the plug off the old park light socket and soldered the resistor in between, one for each side. (The white thing)



I wired in the relay to activate from a red/white wire in the ecu box and took the positive straight off the back off the booster terminal





Would do a writeup but just wanted to get it done and forgot to take photos during sorry.

Oil change of 9.5qts of Castrol European formula 0w/30. Then gave it a wash to knock off some of the dust from sitting at the airport the last two weeks.

After changing the oil with Castrol last year at 13K miles and this year at 21K miles, the oil looked UNBELIEVABLE! It was cleaner in appearance than the BMW/Castrol brand 10x30 that I've changed at 5K miles for the past 10 years on my Bimmers. I was nervous bc I like to change the BMW brand at 5K, but I'd heard that the European formula Castrol would impress. It did! I am considering going 10K on this oil change. Even the FILTER was ultra clean!

Next up is some stainless steel brake lines and a fluid flush, preventative coolant flush and suspect parts, preventative belts and hoses, too. Oh yes. And the transmission, transfer case, and diff fluids. Won't be cheap, but it's cheaper than being stranded!

Added brake fluid which took care of the red "brake" sign and the yellow triangle with exclamation light which is great but I think that may have built more pressure in the system and discovered brae fluid leak. Got rear brake pads fixed and so only Light left on the dash is the airbag light. Got driver door carrier, can finally open the car from the driver side. I guess one thing is scratched of the list to fix, and few more to go.
