These water pumps are know to fail internally. The blade may freespinning. You will need to remove the water pump and inspect.
Or you may have a head gasket issue. Its simple to test if you want a shop to inspect it for you

NORMALY THE HOT FLOW ENTERS THE TOP HOSE AND COOLER WATER LEAVE THE BOTTOM HOSE BACK TO THE BLOCK, SO IF THE TOP HOSE GETS WARM THEN THE RAD IS BLOCKED , IF NIETHER GETS WARM/HOT THEN THERMOSTAT NOT WORKING, OR YOU HAVE BLOCKAGE ELSE WHERE, SO REMOVE BOTH HOSES FLUSH RAD WITH HOSE PIPE, (WHEN ENGINE IS COLD) SEE IF WATER FLOWS OUT AT SAME SPEED AS U R FILLING IT, IF NOT ITS BLOCKED, 2ND REMOVE THERMOSTAT AND FLUSH ENGINE OUT, U CAN BUY RAD FLUSH/CLEANER AND TRY THAT,

yea check ur rack....may be der is not a proper engagement btw rack n pinion....so check it...... cheers!!!!!

Hi there,

Well problem is seems due to the moisture in the car wiring, so first of all stay your car in sun light for some time...... most of the time it resolves the issue.....
let me know if further you have the same problem....

Good Luck!!

Thanks

Wheel speed sensor fault. The sensor also has a bearing on the speedo. They are VERY common. Get an autostore to plug in and give you the code to work out what sensor you need.

The grounding source might be the problem. Or the bulb's filament. Try cleaning the grounding source and the fuse.

Hi There, Not to worrry, this usually occurs when the car is old as long as you ensure your brake pads are well fixed, you can ignore this and continue driving. Just ensure your breakpads have been newly changed.
Cheers.

Hi,

Look for a dial control (near your headlamp switch) and see if you can adjust it back to "0" position.

If there is no dial or headlamp adjustment control, then you will need to take the vehicle to a local garage that has the correct Optical machine and they can align the headlights correctly, for a small fee.

Note: correct headlight aim is a requirement for most countries, before a Warrant of Fitness is issued.

Cheers,

Bad pump. Bosch pump no less. about $120 on line for just the pump. You can also buy the entire assembly which includes the sending unit that reports back to the fuel gauge. auto parts and bmw sell that thing for three times the price. The same pump is used in many many of different series BMW's. After 60,000 miles they are changed out as part of routine preventative maintenance, because a bad pump will leave that hot babe driving it stranded at the mercy of the local bugger pullers.

Hi as the car is BMW the only way you can reset it yourself is to buy an electronic tool that will plug into your cars engine management system, that will allow you to reset this light!!
You can buy this tool from 80-100 Pounds.

Other cars such as ford and peugeot etc can reset there light by using buttons on the dash board, but BMW, Mercs and Lexus don't have this function.
Your local garage will also be able to turn the light off, but will charge a small FEE!! So you will need to decide weather it is financially worth buying the tool to do it yourself or just pay the garage.

If you are planning on keeping the car for several more years if would be worth buying one as it will also provide you with the error codes, should your car have a problem and you will also be able to use it on other cars in the future if you do part with your BMW.

They are worth having if you work on cars yourself, as it will provide you with all error codes.

Let me know how you get on!! And if you need any further assistance. Thanx Paul

possibly a few things, connections, break in the wiring etc. best bet is to get the codes read....hasn`t got to be a dealer these days

In the fuse box.

ANY OF THE CASTROL OILS ARE PRETTY WELL UP TO THE MARK ,I WOULD HAVE NO WORRIES USING IT

check fuse and relay, if its good, than you have faulty switch, only work on low but not high beam, to turn high beam on the switch move forward which is fauty or no contact, flashing high beam move toward you which has a good contact and working. it two switch in one unit.

test power to starter with a voltmeter while someone else turns the key. if you are getting power, than solenoid is faulty. If you are not getting power, than relay or ignition switch is bad. Do double check your battery connections to make sure they are metal to metal contact.

I have an 01 330ci and a similar thing happened to me... The dealership indicated that they have only ever replaced a handful of actual fans in these cars (and that they're tucked down deep in the dash...) but my issue was what they referred to as the "final stage unit." It was this bulky multi-pronged metal plug that went in behind the glove box. I believe it only cost me about $80-$90 from the dealership last summer. And I think only an hours labor from the mechanic I used.

think their is some sort of relay safety device under the seat or in the boot and it needs resetting ,heard other mechanics talk about it but havent done one myself
