Lighting and Cold Start

Hi Guys...

I settled for only reading the forum so far, and I must say I found very good answers to my questions every time... until now! So here it goes!

My car:
1999 BMW 316i Sedan, 1.9l engine (I am European... Gas is expensive here you know... , 185.000 Km

My Problems:

1. When I sart my engine, after the car hasn't been started for 2 days or more, I get this loud clonking metallic sound. It goes on for 5-6 revolutions of the engine after it has started and then it magically disappeares and the engine begins working normally. The whole issue lasts for just 2 seconds or less... As I have told you... just the first 5-6 revs of the engine. It doesn;t sound like the engine banging against some metal part, but the sound comes from somewhere within the engine... Also I want to mention that when I use the car regularly the sound doesn't appear. Only when the car hasn;t been used for a full day or two or more. I hope I made myself clear...

I wish I would know what could it be and how bad could it be...

2. I have auto aiming xenon headlights on my car. Nevertheless I found out I have to aim them correctly because when I bought the car they were all messed up. So I succedeed to do that on the driver's side headlight, using the round funny-edged horisontal knob on the back of the headlight, but i found out that when I tried to do the same on the right side one, nothing happened. It's like the manual aiming system is broken or something. The autoaiming system works correctly but the light is still aiming too low.

So... is there anything I can do about it? Can the aiming system be fixed? or do I have to change the whole headlight (God i hope not)

Please gimme some answers as I don;t know who else to ask.

Thank you!

PS: Please excuse my english if it's not as goos as it should be... I hope I made myself clear enough.

I'll give it a wild guess:
1) Have u check engine oil? It may be too old and dirty. Or u'r using oil that's too viscous so the engine doesnt get proper lube in cold days.

2) It may just be that the knob is broken.

Again, I'm sure there are more knowlegeable ppl out there. Good luck

I had an old Mazda that made noises like that - it would clank and clammer for the first 4 or 5 seconds then clear right up. The oil level was fine and in good condition, and I never solved the problem. Maybe one of the mechanics here can chime in.

As for the headlights, the outer ones adjust the left-to-right and the inner ones do up-and-down. It is a gear that mates to another gear that drives a worm gear on the inside. I'd do a search here because I remember someone here talking about that coming apart (similar problem - turning it does nothing).

Thank you guys...

I think it's an oil problem to... This week I'll be changing it with a 10W40 BMW oil and see what happens.

As for the headlight problem I will have to take it apart and see what's in there... wish me luck...

Any other opinions?

Actually the other thing to check out is the water pump. I recently did the pump on my 99 328i with 140,000km and that cured up a mysterious mechanical rattling noise that occurred on startup. You should do the WP every 80000 to 100000km as preventative maintenance, because if it comes apart it is uuuuugly!

It is a fairly easy DIY too.
