Had a crazy thing happen. Wife's X had a problem a few days ago throwinmg SES with vacuum leak likely.

I checked the intake boot which is the most likely candidate and to my surprise in was in good shape so I pulled on all the connections on the intake pipe and the connection downstream of the MAF fell apart.

No seal! WTF!?

So I had the intake parts off a month ago to replace the alternator and apparently missed one seal putting back together.

Today wife's driving to Milwaukee and 5 miles away gives me a call that car has stalled. Engine running but brakes and gas aren't doing anything.

I come out and sure enough the "driver wishes" pedal on the right does nothing as of the cable came off.

So I drive the car about 3/4 a mile at 5mph with the revs jumping from 1000-1300 so feels like somebody is bumping into my backside every few seconds.

Wife departs and I get to troubleshoot and see if I can avoid a tow.

Scanner reports the throttle is stuck:

And it dawned on me. I haven't found that seal for the MAF. Wonder if it got sucked in.

Using a flat piece of metal as I had no tools I macgyver'd my way into the intake boot and sure as hell damned MAF seal!

I could only touch with one finger the boot hole is too small to fit my hand.

Eventually I get one finger hooked and I can't pull it out.

Tried to reset the engine code because that would rev the engine a bit. Which it did but apparently just by injecting more fuel not opening throttle valve.

Found a pen in the car to poke the throttle plate. Release the kracken!

Troublemaking o-hole!

Reset codes, reassemble the air intake and like it never happened.

LOL! Good thing it didn't go all the way into a runner. Though at it's size I guess that would be a low probability. ;) Well done getting it out at any rate. :thumbup:

Decided to use the X5 tonight to drive to dinner, and upon entering the parking lot (25 mile drive to the restaurant), it decided to grace me with an SES.
Code comes up as 279b Thermostat Jamming. Temp was constant at the center and oil temp was normal, even on the entire ride home.
I erased the code when I got home, then went out for a little 12 mile ride and it hasn't thrown the code again. Coolant and oil temp normal. I'm hoping this was just a glitch.

Unfortunately the thermo dial in the dash is not a gauge. It's a 3 position idiot light: cold, within 30° of operating temp, and overheated.

The problem is, the thermostat can be struck open or closed and be 20° off and the dash will not inform you but you will get shit mpg and run for months rich with a car that won't get to closed loop. Ask me how I know.

I recommend monitoring you actual temp real-time for a while. Use I think hidden menu 7 or 9.

I had a buddy drop a broken off electrode of a spark plug into a cylinder and not realize until he started the car so I was a little concerned when it dawned on me that maybe the o-ring got sucked into the intake.

I wasn't too concerned that it got sucked into the intake I was a little worried it would have broken the throttle motor.

But was happy when the engine fired up and the gas pedal aka "driver wishes" pedal did something.

Started the repairs of my open manhole "finder".....[emoji2959][emoji857][emoji857]

I know about how the gauge works, and did use the hidden menu. Never heard of a BMW thermostat failing in the closed position, but I suppose it is possible.

On second thoughts it appears it is running colder than it should on the highway. This is about as hot as it got driving about 40 minutes on the Pennsylvania Turnpike.https://uploads.tapatalk-cdn.com/202...317f5b6d93.jpg

That is a little on the cool side...

That’s Highway. Around town it’s 93-95. https://uploads.tapatalk-cdn.com/202...8787673c0e.jpg
