Oh I forgot to mention... I let the car warm up for just over 5 mins this morning.. No hesitations nothing. No smoke either.

I remember when Martin had a quick look at my car some time ago when he said I had non-standard injectors that the problem is common and possibly caused by the coolant temp sensor or somthing?!? Personally i don't think it is as it idles higher when cold then drops slowly once warm.

If you don't like the sound of the 044 mounted externally, I can agree with you here, I believe you can mount them intank and they are a lot quieter? I never did it, but mine was externally mounted and it is very annoying and loud especially in the summer. Intank should be a lot better.

if u want to check the knock sensors (it may be wrong but its a 2 minute check and is really worth the small effort), then do this.

Stand over the battery and look at the intake manifold. Get a torch or long flourescent light and place it between the battery and manifold and somehow get it to stay there.

If you look between runners 1-2 and 4-5 of the intake manifold then you should see, in each, a small green plug with a white clip attached onto it. This is the knock sensor. in my case the white clip (and attached wire) were hanging there doing nothing. took 2 seconds to plug it back in. The green plug is about 1 inch long and is cylindrical...

as i said it may be completely wrong but it only takes 2 minutes to have a look and see if they are plugged in...

      Magnetic Drain Plug Snapped in Half

      By kevboost7 路 Posted

      Update: I got the magnet out. I bought 3 different flexible magnetic reach tools, but none of them worked. The magnet on the tip was all less than 2lbs of force, so i had to buy a special cylindrical magnet that had a pull force of 9lbs.  The magnet finally came in the mail yesterday, so i got under the car to get to work. The super strong magnet isn't that long, so i only have about 1 finger pinch lengths to hold it. I was so scared when i was going in the hole, that the 9lb magnet would just fly away inside the oil pan never to be seen again, but i had my butt cheeks clenched and finger gripped on that thing so tight, i managed to get it to suck the other magnet out.  It was a victory for me last night.

      New fix for low tyre pressure from bmw

      Yep, pretty much what you said is a good summary. The aftermarket thing just attached to the rim, then has two lines out to valve stems, one to inner wheel, one to outer wheel. Some of the systems even start to air up as you head towards highway speed. IE, you're in the logging tracks, then as speeds increase it knows you're on tarmac and airs up so the driver doesn't even have to remember. I bet the ones that need driver intervention to air up end up seeing a lot more tyre wear from "forest pressures" in use on the highway!

      Anyone know this frontpipe?

      Yes, but you need to do these type certifications for tuning parts. That is the absurd part here. Meaning tuning parts are very costly (generally speaking) as well as the technical test documentation for say a turbo swap with more power. It just makes modifying everything crazy expensive and complicated. That bracket has been lost in translation many years ago I assume, it was not there.

      Hahaha, yeah.... not what you'd call a tamper-proof design.... but yes, with the truck setup, the lines are always connected, but typically they sit just inside the plane of the rear metal mudguards, so if you clear the guards you clear the lines as well. Not rogue 4WD tracks with tree branches and bushes everywhere, ready to hook-up an air hose. You can do it externally like a mod, but dedicated setups air-pressurize the undriven hubs, and on driven axles you can do the same thing, or pressurize the axles (lots of designs out there for this idea)... https://www.trtaustralia.com.au/traction-air-cti-system/  for example.... ..the trouble I've got here... wrt the bimmer ad... is the last bit...they don't want to show it spinning, do they.... give all the illusion that things are moving...but no...and what the hell tyre profile is that?...25??? ...far kernel, rims would be dead inside 10klms on most roads around here.... 馃槂

      You're just describing how type certification works. Personally I would be shocked to discover that catalytic converter is not in the stock mounting position. Is there a bracket on the transfer case holding the catalytic converter and front pipe together? If so, it should be in stock position.
