Question QUESTION: what does it mean if im getting a jerk when i apply breaks to my 2003bmw 325ci
ANSWER: pulsating brakes are common on BMW and MERCEDES..
It means your brake rotor disks are warped..
Dont both resurfacing them..they will warp again soon...they will be too thin at that point.
Buy new rotors on your next brake job..and buy good grade brake pads..not the cheapies.. they will hold up to heat better...
Good luck..

QUESTION: can you give me any tips to help me keep my bmw running smoothly?
Answer FIGHT THE RISING PRICE OF GASOLINE
HERE ARE SOME TIPS FOR ALL OF US TO USE TO SAVE $$ ON FUEL
1. PROPER TIRE INFLATION.......
TIRE UNDER-INFLATION IS THE #1 CAUSE OF FUEL WASTE AND PREMATURE TIRE WEAR.
SMALL CARS SHOULD RUN 32-35 PSI TIRE AIR PRESSURE
LARGER CARS AND PICK-UP TRUCKS 35-45 PSI..
THE MAXIMUM TIRE PRESSURE IS STAMPED ON THE SIDEWALL.
IF YOU HAVE LOW AIR PRESSURE IN YOUR TIRES,
IT MAKES YOUR CAR MUCH HARDER TO ROLL.
ALL TIRES LEAK! CHECK THEM OFTEN!
2. PROPER ENGINE MAINTAINANCE.
SPARK PLUGS , WIRES AND OXYGEN SENSOR SHOULD BE CHANGED EVERY 45-50,000 MILES. TO INSURE A STRONG SPARK.
AND PROPER FUEL AIR MIXTURE.
3. CHANGE MOTOR OIL AND OIL FILTER EVERY 5,000 MILES
AIR FILTER SHOULD ALSO CHECKED AT EVERY OIL CHANGE.
YOU MAY NEED TO REPLACE IT ABOUT EVERY 2 OIL CHANGES.
BASICLY…IF YOU CAN’T SEE DAYLIGHT THROUGH IT,… REPLACE IT.
.THAT WILL HELP YOUR ENGINE BREATH BETTER ,
AND GET ENOUGH AIR INTAKE TO RUN PROPERLY. AND MORE EFFICIANT.
DIRTY AIR CLEANERS MAKE YOUR ENGINE WASTE FUEL!
4. CHANGE YOUR DRIVING STYLE
EASE ONTO THE THROTTLE TO GET THE VIECHLE ROLLING.
THEN TRY TO MAINTAIN SPEEDS WITHOUT INCONSISTANCIES.
IF YOU SEE A STOP AHEAD......JUST COAST THERE IF YOU CAN.
NO NEED TO RACE TO THE NEXT STOP. GET OFF THE THROTTLE.
BASICALLY TRY TO REMEMBER.
LESS THROTTLE. LESS $ GAS $ WASTED.
5. PROPER WHEEL ALIGNMENT
WHEEL ALIGNMENT IS ALSO VERY IMPORTANT. THIS WILL AIM YOUR CAR STRAIGHT. IF YOUR WHEELS ARE PROPERLY ALIGNED. YOUR CAR WILL NOT ONLY ROLL FORWARD EASIER. IT WILL ALSO GET BETTER TIRE WEAR. IF YOUR CAR IS OUT OF ALIGNMENT.YOUR TIRES WILL WEAR OUT UNEVENLY AND MAKE YOUR CAR WORK HARDER TO ROLL. YOU SHOULD ALSO ROTATE YOUR TIRES FRONT TO REAR EVERY 5,000 MILES OR AT EVERY OIL CHANGE.
THESE ARE THE MOST IMPORTANT THINGS THAT COME TO MIND
WHEN TRING TO SAVE FUEL.
I HOPE I GAVE YOU SOME GOOD IDEAS.
