I believe the manual says every 40k miles for the plugs... no idea on coils. I'm MHD Stage 2 tuned, heavy into autocross about to do my second track day. Plugs were an easy decision, and since I had to remove the coils to change the plugs, just figured I would do it all at once.
I would think that the shop did that with sensor replacement but I will validate.
I just cannot understand why pounding around a track won’t trigger it but smooth interstate does. And this time I was sitting still and that dreaded tone and popup hits.
Sure, a restart clears it. Sometimes for a few days, sometimes for a few weeks. But it always comes back. Always on flat smooth interstate. Never when I’m pushing the car in autocross, mountain driving or at my track day.
I clear the code with BimmerLink but sooner or later it always comes back...
F' me! It's back. Exactly 30 days since the front ride height sensor replacement. Not during my track day. Not during my road trip to and from the track. No... sitting in bumper to bumper traffic, on the flat damned interstate! Sitting. Not even moving. As in FULLY F`ing stopped! And...
Front sensor replace, no code since, including 550 mile round trip from Orlando to Roebling Road Raceway, and a full day of track time. So far, so good.
Took about six weeks, and once again cruising down a flat interstate... I get the error. Two autocross events... no issue. Just driving to work, and this damned error message pops.
Ride hight sensor brackets are fine. I think I'm going to replace the actual sensors, and see if that solves...
Got it off! Thank all for the tips! Small flathead screwdriver gave me enough leverage to pry it off, and yes, there is a metal band/clip embedded in the rubber.
New boot should be in my hands tomorrow, so I'll be back in business soon. No more doom and gloom.
I've tried using a pick tool, will need to try a small flathead screwdriver I think... If I understand correctly, i need to pry what is remaining of the boot, which is held on by a hidden metal ring, off the cylinder part of the caliper. So the yellow part in that last photo from the tech...
Totally different. I ordered part from Toyota and it’ll be here Monday. But I cannot figure out how to get this one off.
Once again I’m in over my head. Never seem to learn.
