Yeah, mine is in the pit as we converse. Lambda was off, O2’s were flatlining. Initial road test revealed a severe loss of power. But again, we’re still working to find this hiccup at the end of the rpm range.

Another great place to kick back OB. Look up the "Bear Lovin Cabin" if you don't have a place to stay yet. The Mrs will love it, and Black Beauty's all wheel drive will come in handy on the slick mountain roads.

Where I'm at 800 miles of shoreline is called the ocean and I don't think there's a name in Arabic for lake [emoji28]

Glad you are out and about with your best half (and the X5) too!

Let me know if you are in Abu Dhabi and I can see if they'll issue me an exit Visa for a few days. [emoji106]

Good feedback about the cat v oil consumption.

The tech had also found the secondary air injection ports were packed with carbon which wasn't helping the air pump durability either. Probably consuming more oil through the CCV than normal from the excess crankcase pressure too.


Makes me wonder just how long the cat had been deteriorating.

I rewarded Red's good behavior with a minor detail today. Wash & wax, engine bay wipe down, and interior wipe down/vacuum.

Added these, courtesy of SpookX5, all the way from the Netherlands. Gotta rep the Outpost. Thanks for having these made Jordi, they were worth the wait. :thumbup:

After completing all of that I decided to have some more fun with the coding setup. I re-coded the LCM to play nice with all the LEDs on the truck as the cold and hot monitoring codings had been reset when the ZCS was changed. This took care of some errors being reported in that module.

Then I decided to play with INPA and see if I could diagnose the ALC system that hasn't worked in years. Only the right side headlight would function as adaptive lighting. The left was fixed and actually had to be jumped just to activate the low beam (I have a thread on that somewhere). This is necessary because the LWR (main control module that runs ALC) disables the headlight when it detects a fault. I assume to avoid blinding oncoming traffic? I found a setting in the module that can be turned off to defeat this fail safe but I left it on.

So I ran through some of the activations, live data, etc INPA offers and found all the motors were good in both headlights. I could not see any real differences in what the headlights were reporting one side vs. the other excepting what the ride height sensors were reporting. I did find a counter (offset counter I think?) and it had a reset option. So I went ahead and reset it. I now have 100% functioning ALC again. I even managed to get the wife excited with that one. :D Because the system hadn't worked in so long she just figured it never would again. Never count an idiot with a laptop out! :nanana: Thinking about it though, I'm wondering if the offset with the height sensors were playing havoc with the EHCII system as well? I seem to remember reading a couple threads here where counters needed to be reset after servicing certain components. That's just a guess, but it makes sense to my tired brain.

So all in all, a pretty productive day in the garage. Now I'm beat.

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

I knew Red would play nice!

Red by the way, is also STUNNING! [emoji106][emoji106]

The X5 is looking very nice crystalworks! The red Xoutpost sticker was the only right choice :cool:

Looks outstanding as usual! For a guy with a new BMW diagnostic computer, you seem to have caught on pretty quickly. Did it come with ISTA as well?

Update on the ALC lighting fix now that I have had some sleep. The system is good to go now which is great, but I remember now what happened. I had some water intrusion into the LH headlight (after I modded the lights back in 2016) and it fried the ALC module on the bottom of the headlight. I replaced that module with a good used one (multiple actually) but the system never worked again. I think it had to be reset on the software side before it would all play nice together. So the actual fix was the used functional ALC module combined with resetting the system. Just wanted to clarify that. :thumbup:

Thanks guys. She's become a quasi garage queen and it is kind of nice to see her clean almost 100% of the time.

Thanks. It has a learning curve that's for sure. I spent about 10 hours reading up on the BMW software suite over 2 weeks before diving in to familiarize myself with it. I wanted there to be as close to zero chance of borking a module as possible. I downloaded all the software stuff and installed it onto a Win 10 laptop. That wasn't too bad, but had to track down all the missing Microsoft .dll's and such that cause the software to not work initially.

I have ISTA + as well but have not tried to install it yet. I am anticipating it fighting me though when I finally get around to it.
