BMW E46 brake pressure sensor

[@Misbah007]

Do you have to drain and bleed the brake before changing the sensor

[@PetitTintin]

Hi I have the same fault code on my car, Did you felt any difference on the braking power after replacing the sensor ?

[@st4nee]

Could I get this error when I did not get all the air out ? I put new brake caliper to rear, and it shows 10 pressure less in rear than front, hope u understand.

[@NewLevelAuto]

A Sandy video requires I take a 5 minute break mid work day. Thanks for sharing as always !

[@sandyande]

New Level Auto cheers Keith, wait to I tell u this breaking news........ I went and purchased 2nd hand autel ms509 via eBay for £600 the guy paid £1365 brand new in august last year! it is a registered autel UK machine but went to do software update and it crashed so it's shipped back to autel, should have took your advice and got launch, I blame Eric o he makes autel look to good cheers sandy

New Level Auto haha true cheers

[@sandyande]

New Level Auto it's actually the ms 905 oops!

[@Mr_Ryote]

thanks for this, sensor 2 on my new toy is faulty and this saved me playing about

[@Racelinekarting]

Great video. I have those exact lights on but as of yet haven’t got my hands on a code reader. Can I ask how your car was running whilst those lights are on? I have the 325 petrol and the engine is hesitant and restrictive on power the further up the Rev range I go. Interesting these lights will go on after the car has been left quite a few hours and the engine runs normally again, until the lights return then power is reduce and almost wants to stall. So just wondering if I have the same issue as yours or maybe something different.

[@sandyande]

My car was running fine cheers sandy

[@aor3200]

Just want to confirt, sensor 2 is the nearest driver (the rear one) ? and sensor 1 is the engine side?

[@sandyande]

Yes

[@brandonlee8445]

Could these sensors make your rpm go up when you press the brake pedal if they’re bad?

[@sandyande]

No

[@jbaroli]

Pretty sure you have an air leak in your brake booster...

[@burakasiliskender]

Is this DIY hard? as both my sensors need replacement

[@sandyande]

Burak Asiliskender it's a bit tight but it can be done cheers sandy

[@imrejuhasz8121]

Hi Sandy, Im having the same problem it's just on dash on may way home from fishing🙈. anyway after replacing does requires the system bleeding? Thanks

[@sandyande]

Imre Juhász hi I never got roung to replacing it the lights goes of for months then comes back on intermittently, have just learned to live with it !! Cheers sandy

[@salahelbahji705]

Hi I have the same light on the dashboard But when I read live data it’s 0 bar for both of sensors What you think? Thank you for the video

[@sandyande]

If u can try different scan tool or back probe sensors to see if u get varying voltages when brake pedal pressed

[@whichdoctor4858]

Is that your DISA rattling?

[@kennyspringer7668]

I have this problem at tells me we'll sensor 1 and wheel speed sensor 2 on the right hand side front and rear however sometimes it goes away and then comes back on could it be that I just need to clean inside where they meet on the middle of the wheel

[@ryansomerville5679]

thank you, I got a £20 cable and INPA software off ebay to find the fault before coming here to find out which one I need to replace. (Just so you guys know you don't need to buy a professional £1k+ reader like that)

[@isrealperez9069]

My o4 Xi is it located at that side it's on the passenger side

[@raymorris952]

Thanks fella, mine has shit out number 2, I now know what one is number 2.

[@aor3200]

Hello did you found out which one was sensor 2? Was it sorted with replacement sensor?

[@HardeepSF]

i'm currently having the same things changed on my E46 M3, i also had the same two lights show up on the dash

[@kevintorrissen7667]

figured out the problem? just replaced mines, and have still that problem.

[@HardeepSF]

@@kevintorrissen7667 yeah was the brake pressure sensor

[@dynoshifty1361]

@@HardeepSF how did you fix?

[@HardeepSF]

@@dynoshifty1361 changed the faulty sensor

[@roborovsky6950]

@@kevintorrissen7667 even doe it's been 2 years, someone else might find this usefull. Those 2 dash lights might also be caused by faulty abs sensors on the rear wheel, steering wheel angle sensor, and sometimes the wheel geometry. A tester that can connect to your abs module will clear it up, so don't start throwing $$$ before knowing it for sure!

[@casperthespottydog]

Sandy, I had this problem with a friend's beamer a couple of years ago, turned out to be the brake fluid was full of bubbles maybe causing the sensor to give funny readings, just a thought for you before you buy a sensor

[@sandyande]

casperthespottydog cheers I'll check that out, sandy

[@SpartanA31xx]

Hey so just to clarify. Your friend beamer had DSC Pressure sensor codes but when you guys bled the brakes the codes/errors all went away for good? Thanks!

[@omegaart]

What diagnostic are you using ?

[@ppppugh7892]

Good question... hmmm? Good vid too, thx.

[@JTTL1]

Terrible. No solution. Literally just scanned the car. What is the point in that?

[@peterO73]

It links warning lights, engine error code, physical location of the sensors and which sensor is #1 and which is #2. It may not be helpful to you, but it does help and I'm glad Sandy posted it. He's a cool guy and his posts help a lot of people.

[@ajmal779]

I have the same problem on my bmw e46 with those lights on can it passed the MOT in uk please can you message me back excellent video mate

[@BMW.e46.Carplay]

No

[@Misbah007]

Mate I don't have any code but I have those 2 light on yellow.same as yours . any help will be appreciated

[@sandyande]

These lights usually appear in the hotter weather and mines go out when the temp goes below 20*c , wait and see they may just go out

[@Misbah007]

@@sandyande .thanks mate .I will wait and see

[@MrLilski79]

Great vid now I know witch is sensor 1👍

[@kennyspringer7668]

Also I have changed them to use ones and clean them several times just still lighting up the dash

[@sandyande]

Kenny Springer hi I never changed the pressure sensor as it started working and light went out, what faults are shown on scan tool?

[@luddeluring]

Thanks a bunch for this video 👍🏻 I got this error today on my way home from Work 😥 hooked up my scan tool and it said it was pressure sensor 2 and also when doing the live data it showed different pressure, just wish I had a right hand drive car, it’s impossible to get to these sensors on a left hand drive car!

[@sandyande]

Just leave it as the fault usually disappears all by itself!

[@luddeluring]

Thanks for your reply! So it’s safe to keep driving?

[@sandyande]

Yes

[@luddeluring]

Well wouldn’t you know it! Drove in to work this morning and the warning lights where still on, but just now I had to move my car and the lights where off! Is it just another one of the bmw electrical gremlins or do you think that the sensor is actually going bad?

[@sandyande]

@@luddeluring hi look at casperthedogs comments further down he says it caused by bubbles in brake fluid!

[@tommydargydarg1775]

Very helpful, thanks!

[@seanfox6947]

Cheers lad!

[@erwinfelgendreher]

Where is Sensor 2

[@peterO73]

Beside sensor 1, it can be seen in the video.
