Sounds like the power ballast is failing - that's what takes the 12v signal from the car and amplifies it up to a level sufficient for driving the xenon bulb. Swap the ballasts between the headlights (they're easy to dismount) and see if the flicker goes to the other side (swap only the ballasts - leave the bulbs in their existing positions). If the flicker moves to the other side, the ballast is the problem. If it stays on the left side, the bulb needs replacement.

Search online for the bulbs - the dealer will kill you on pricing (the Audi dealership wants $200 each for my A4's xenon bulbs, but I can find them online for about $30 per pair (or less)). You'd want to order a D2S style bulb for an OEM BMW fitment, in 4300k color temperature.

typically the headlight fuse is separate form all the other fuses in a different location in most American cars the engine and lighting fuses are usually located under the hood in the engine compartment

could be a vacum leak the break system uses an air diaphram to help assist on the power side of the breaking system go to how stuff works .com and look up how breaks and mastercylinders work it will explain how it uses vacume to assist the master cylinder but it sounds like u have an vacume leak

Check and replace if necessary the fuse no.# 41 (30 Amp.) placed in the fuse box / relay plate fascia 1 in the glove box. See pictures below:

Make sure you dont run out of fuel, make sure 1/4 tank of gas is always there and the reason is that the fuel pump should be submerged in the gas all the time, if not then it will heat up and die.
It would also be good practic to change the fuel filter once a year, if there is no external filter then ad one in line filter for your safety.
As for the mis at idle it could be due to bent valve, burnt valve seat, vacume leak, head gasket minor leak, bad coil, shorted plug, bad gas. If the engine light is on which it should have because of the missing then I would like to know the codes.

The 4 main reasons usually why a vehicle just cuts off are as follows 1 restricted fuel flow which you could rule out easily if the vehicle sputters or hesitates lets say climbing a hill or under heavy acceleration 2 a faulty map (manifold absolute pressure) low barometric pressure signal received can cause vehicle to cut out 3 a faulty idle control circuit which is usually preceded by an erratic idle but not always 4 a faulty maf (mass air flow sensor) which over time the probe can build up residue and cause vehicle to idle or rev up erratically or cause your vehicle to cut out as well. I'd have it checked for trouble codes whether the engine light is on or off and you can have a full diagnostic scan which would systematically check the vehicles sensors and functions before replacing any unnecessary parts

Check the bearings in your wheels. If you had to get an alignment, there is a strong possibility that your wheel bearings are worn down. Hope this helps! Please rate 4 thumbs up!

very well could be the starter. you won't nessacarally here a clicking or anything. the only way to tell for sure is to take it off and have it tested. auto parts stores do it for free.

I posted this link to the ebay store where I bought mine owners manual, if you looking for good and cheap book or pdf file just go there and check it out.

Check your fuses, check the starter, check the battery for sufficient voltage ...

Well, replace the offending unit, then bleed the air out of the system...Sometimes you have to remove components and invert them to get all of the air out.

The headliner has to come out to access this area of the frame.
The leaking oil runs down the frame into the fender in front of the rear tire and leaks out onto the ground.The cylinder over the window is pretty close to the front of the frame. I suspect a pinched or otherwise damaged line may be possible for the leak.

To replace these lines you do not have to remove the headliner or the top material, the only lines that require removal of anything big is the main cylinders and the valve block. To replace these you need to remove the complete top assembly which sounds a lot difficult but it comes out pretty easy. But your problem will not require the top removal.------

theres two terminals on top of your battery.. usually they are a 10mm. take eaach terminal off. then there should be a battery hold down. it can be on top of the battery, on the side, you just have to find whats holding the battery in the tray and take that off. then place the new battery in the car. put the battery hold down back on. and then re attach the two terminals... one is + and one is - make sure you dont mix them up when putting the new battery in...

Check the universal joints on the driveshaft.
