Mein Auto: 1997 BMW Z3
Z3 Where is this part?

Hit a P1505 code on the car when running a diagnostic check.
Idle speed control valve selenoid blah blah blah.

Have searched and searched but I cannot find any pictures or "how-tos" on how to find, remove, or replace the idle speed control valve on the 1.9l.

Frustrated.
Any help would be wonderful!

MGBs!

I still love them; my first was a new 73 Rdstr (Blaze/Navy) and that led to a whole string of them over the next (almost) thirty years.

I think I had sixteen (16) in all, ranging from the earliest, a 66 Rdstr through several GTs, including one I put a Buick V6 into and a 74-1/2 GT, up to a 78 Rdstr.

Pretty sure that if pressed into working on one, I'd still have all the tools needed memorized

Keeping the faith, I still have my Big Healey, purchased in 1978...

I'm not all that familiar with the Z3 models (mostly just the ///M versions) but the ICV for my 99 is located just under the intake manifold towards the rear. It is very conceivable that the "turkey neck" (a gray rubber grommet) has perished, causing a vacuum leak. The unit tends to get gummed up with carbon deposits, and it sticking is another potential problem. Seems that I fixed that on a neighbors 3 Series last summer (he was trying to get me to do as much as I could on his car before I moved to Florida). Good chance that I have some pictures of the offending component; give me a chance to look for them...

The M44 idle regulating valve is not quite as glamorous as those in the I6's (Part #9):
