Tip & How-To about 2003 BMW Z4

Washing your Cloth-top

Vacuum the top with a brush attachment, then rinse thoroughly with low pressure water to remove loose soil. Spray RaggTopp Cleaner evenly over the entire top and scrub lightly with a soft nylon brush. Then rinse thoroughly with low pressure water until no remaining soap foam is seen. If any difficult soiled areas remain they may now be spot cleaned by applying RaggTopp Cleaner directly, letting it stand for 10 to 20 minutes, scrubbing with a soft toothbrush, and then thoroughly rinsing the entire top again. Do not attempt to remove contaminants by scrapping with any sharp edged tool. When the top is clean dry it with a microfiber towel. After washing the top the car must be washed to prevent spotting or filming. Leave the top up until it is completely dry. This may take an hour in direct sun, or as much as 24 hours in cool, humid weather. After the top has thoroughly dried its water repellency must be renewed

no electrical power

There could be a couple reasons for this. The most common is corrosion on the battery terminals (see illustration). Any auto parts store will carry 3 things:
1. Battery post cleaner tool/brush. Though depending on the type of battery terminals you have, a regular wire brush works good for the side bolt kind.
2. Battery terminal cleaner/acid neutralizer.
3. Battery terminal protector spray

First, remove the battery cables from the battery. Next use the cleaner (2) on both the cable ends and where they attach to the battery. Let it soak for a few minutes according to the instructions on the can then rinse with water. Use the wire brush (1) to dislodge any stubborn crusty bits. Re-apply the cleaner if needed after brushing. Next, let dry and then spray with the protector spray (3) to help prevent future corrosion buildup. Finally, re-attach the battery cables and see if things are back to normal:)
In extreme cases, you may have to replace the battery cable end, while this add a bit of complication to the fix, it's easily accomplished with a few basic tools, but don't forget to make sure everything is clean and protected as instructed above to prevent further issues.

Check for vacuum leaks. Spray some carb cleaner or WD40 around the intake manifold, trottle body and any vacuum lines. Check for loose connections on engine wiring harness (Maybe you disconnected a sensor, and forgot to re-attach it?).
