99 z3 2.8l roadster

[Sijray21]

Came across this Z3 at Katie's C&C on Saturday.  You should repaint yours this color ASAP 

Funny you mention that. My mom's first z3 ('97 4cyl) was that color (Red w/Black Top). I'm always a fan of red cars. Not a huge fan of silver, but i won't complain for what i paid for it, haha.

That one even has the seat belt guides on the seat intact! That's rare... and a PITA to fix...

lookin good Jay, you're a braver man than i to attempt all this electronics stuff.  that headlight refinish came out nice too.  such a satisfying job to clear those off.

It's really simple, honestly. If you can change an outlet in a house then you can do some of this stuff. Just disconnect the power supply so you don't kill yourself and it's just copper and plastic. The vacuum issue for the SAP is annoying though. I don't have any vacuum testers and i don't want to throw parts at the thing, so it may go to the shop. Apparently to get to some of the other parts i'll need to take off the throttle body, so i may try that tonight. I'm also just itching to get it registered and feeling lazy, so I'll get a shop quote, too.

I've cleared all the SRS codes except the passenger seat side impact ones. i haven't replaced that sensor yet, but it looks like i'll be taking that seat out again to replace that one later. sensor ordered.

So far for the Secondary Air Pump Issue:

- Secondary Air Pump is working (switch/relay for that must be fine)
- the Check Valve (one that bolts to the head) doesn't seem to be the issue since the tube going to the pump is clean

Thinking right now:
- an issue with the electronic valve (part 5)
- maybe a fuse for the electronic valve (i'll check this first)
- a faulty non-return valve (part 6)
- a leak/bad connection with any of the vacuum tubes/connectors in-between the Check valve and the Intake Manifold





The ABS issue may take a while though. apparently no diagnostic tool will tell me the exact problem, so testing with a multimeter may have to be the way to go...
