Question about 2003 BMW 325

Open Question

How do you replace a parking sensor on a 2003 BMW 325i tourer . One of the 4 sensors does not click. How is it fixed into the trim? Do you have to remove the bumper trim. How long is the lead and where does it plug in to the car's wiring. Do you need any trim clips or anything which is likely to require replacement appart from the sensor?

    I've now managed to remove it, put some WD40 on the plug contacts replace it & it's working. For the benefit of others It helps to see a photo of one on E-Bay so you know what you are dealing with.
    The sensor was held into the trim largely by friction (& Dirt) and a small clip which latches over a lug on the cylindrical body. Push this clip away from the sensor and firmly push in on the sensor until it comes out of the trim and can be withdrawn from the back. This is far more difficult than it sounds as the sensor is tight in the hole in the trim. Once it starts moving a bit use some WD40 & push it in & out to help free it. When it's dangling down the back of the trim use a small screwdiver to unlatch the 3-pin plug which engages the socket on the back of the sender and spray some WD40 on pins & socket engage & disengage plug a few times & with luck it will clean up & start working like mine did. No need to remove trim but small hands help. My car has the detachable trailer hitch so removal or the hitch panel in the trim helps access to the 2 middle sensors.

The motor is replaced from under the hood, you have to remove the cabin ai filter housing. It is can be a hard job. Most dealerships will charge 3 hours labor to do it.

SOURCE: how to replace rear shocks on 2003 bmw 325i

You have to take the trunk liners off of both sides. There will be 3 13mm nuts on each side for the shocks, and under the car is a 16 or 17mm bolt that has to be removed. I hope this helps.

How to adjust air fuel mix on 325i bmw

That unit reports the exhaust gas composition to the ECM which adjusts the mixture according to the MAF/VAF sensor readings
Add to all of those the ambient temp sensor and the BARO sensor and you have the system that adjusts the air/fuel mixture

My oil indicator symbol is lit but my oil level is OK,but it felt sluggish as well 2003 BMW 325i I have also had the oil can 'orange' symbol come on for about 6 seconds on a number of occasions recently

Hi dennis,

It sounds like you have a malfunctioning oil level sensor. Even with the oil level correct, if the oil warning indicator comes on after starting, the sensor is reading incorrectly. I would recommend replacing the sensor with your next oil service. As far as the sluggishness, the sensor operation will not affect that. I suspect that is a different issue.

I have a 2001 bmw 325i. When the brake light shows up on the dash. How do you know if it is the front or rear brakes that need replaced? Also how many brake sensors are there? Does each brake have one?

When the brake sensor light comes up it normally should show a small message on the screen which side is it, there are four sensors on each wheel and the only way to know which ones are to be replaced is to physically exam them. Take the wheel off and have a look if they are less than 5mm replace them.
