My X finally came back today and is running like a top. She should be after almost 3 weeks languishing in the land of broken BMW dreams (my Indy’s staging lot). I tried the easy trifecta fix and bought an eBay module, which didn’t work. I then considered sending one of my now two modules off to be reworked, but ended up biting the bullet and buying a new DSC module. I thought it would need programming, but it was plug and play. In for a penny, in for a pound with this car I guess.

While it was there he put in the rear Bilstein B4s I had been trying to find time to install, adjusted the parking brake, and put a new aux water pump in as the OE one failed as he was troubleshooting the trifecta.

Speaking of suspension, I spent the day installing a four corners Arnott Spring Conversion kit on my wife’s 2015 Jeep GC Overland. Last air suspension car I’ll ever buy. Worked great until it developed a leak a few weeks ago. Compressor was running way too much, leading to an intermittent dash warning. I suspected the right front strut, but the 20 gallons of soapy water I sprayed onto every likely candidate piece and part turned up nothing. Fronts are done and the rears will be tomorrow. Pretty straightforward, but a pita none the less. I will say the left front axle does need to come out of the diff (both need to come out of the hub), a process that was infinitely easier than the same axle work on the x5. The a quick tap on the end of the axle slid each out of the hubs, and a light pry with a pry bar popped the inner splines out of the diff. Arnott provides some electrical trickery to splice into the wires leading to the box that controls the air suspension is suppose to fool it into not lighting up the dash with service warnings.

Next owner will hopefully thank me as the the system uses nitrogen, has a zillion parts, any of which could be failing, and the air struts are over $1000 each and on indefinite back order according to the local Jeep dealer. Very un jeep-like. Car is going to be sold soon.
