    Folks, I have a 2001 E46 320D with the usual pulsing brake issue, my question is to understand how to determine if its the caliper, disc or perhaps the lollipops..its not consistent in that the severity of it varies, no particular pattern but you can feel under light and heavy braking from time...

    Hi All, I just bought a 420d M sport coupe on Thursday, Auto gearbox 18,500 miles. I started the engine and left it idling for a few minutes while I was playing with the IDrive and noticed a slight pulsing coming from the engine. It isn't loud, but it is enough to rock the car very slightly. It...

    Hello, I have a strange issue that I've noticed happens when the driver or passenger front doors are opened and the engine still running. The under door lights (puddle lights) pulse (brighter and dimmer) very rhythmically. I assumed it was either a voltage regulation issue or bad earth etc...

    My 2008 E90 320i (N46) makes an odd pulsing noise once it's warmed up. It can be heard clearly through the dash. From listening to it under the hood, it sounds like it's coming from the bottom of the engine bay. It sounds like a washing machine washing cycle - swooshing noise about once a...

    I have a small (very small) fluctuation on the idle. Maybe an increase of 50-100 rpm, you can't see it on the rev counter but you can definitely hear it! Sort of like the heater matrix pulsing on an E46 when the FSR isn't very happy. I am going to check the intake for leaks - including the MAF...

    Hi everyone, I have just purchased a 2001 728i That has a bit of a problem..... The ABS light comes on (But resets everytime you re-start the car. and there is a 'pulsing' (like ABS Activation) through the brake pedal. A friend has a SnapOn fault reader, which he is sure will find the...

    no matter the temperature setting or power of the blowers, there is a constant pulsing, completly regular. when i had a similer problem in an old vauxhall, it was a heater resistor at fault (blower would only work on setting number 4, not 1,2 or 3). do the bmw's have a similer device that...

    Now I've finally got to drive the damn thing after over a month of sitting, I've noticed something tonight: At idle when it's warm, so around 700rpm or so, the dash lights (only noticable on the OBC) and the headlights (noticable on the reflection on the car infront) seem to flicker or pulse...

    Hi, I'm a new BMW owner, converted from VAG group. Just bought a 2003 320d M Touring. I've just discovered a quirk of the car/fault. When cornering on long constant radius corners in the wet at around 75% max corner speed the car seems to shudder/pulse at around 2 cycles per second. Concurrently...

    Hi guys, Still loving my 330i Touring but got a strange one with the blower motor. When it is between min and max speeds it pulses - at max it is fine - not so sure about min as it is too quiet. Does it with the engine off or running. Only just started doing this and all climate functions are...

    Hello all, A new problem occurred to me today. All of the instrument lights including exterior lights pulse lighter then darker. So, when the headlamps are on they appear to 'flicker' every half second. its a constant thing. Sometimes it stops when the car is idling, but not always...
