I was getting the DSC, ABS, and brake dash lights, along with the pressure sensor code. I pulled the connector, sprayed some contact cleaner on both sides, and gave the pins a very light scrubbing with a brush. Carefully reseated the connector and all the errors went away! THANK YOU!!!

[@trueblue7892]

Thanks Mate that sorted my problem out, it was exactly the problem you showed and the fix was simple.

[@jenniferwoodward2738]

Stuck in heavy congestion on the Bruce highway and these lights came on, got too destination finally and did this and now all clear, thanks heaps.

[@Hardee03]

Thank you! It worked on my Car!! DSC Light is now out, i have done what you have instructed.. My Car has got the 52E1 error and the DSC light is on.. again thank you for this!

[@deemdoubleu]

Thanks will try this. I think these kinds of problems can happen in a lot of older car electrical systems where the electrical contacts become oxidised/tarnished (maybe dependent on climate too). I think in your case, this must have happened, re-seating the connector basically cleans the contacts.

[@advent07922]

many thanks Bro. worked perfectly. mine was showing error with both sensors and clearing the code with computer solved nothing. your tricked worked beautifully

[@philgarofolo205]

Thank you! This worked for me too. There was actually some gunk under the connector which I cleaned up. I may put some dielectric grease on them later.

[@wydras17]

Thanks a lot! Your tip worked for me! Although, in my case, access to the DSC connector isn't so convenient - the DSC is under the brakes reservoir (left-handed 330d). Diagrams in INPA revealed the "Offset pressure brake circuit 1" was firstly stuck at 10 bars, after few "reconnections" offset slowly returned to normal.

Worked for me and my 2000 Z3. My car couldn't move without the DSC kicking and the brake pump would start to run constantly. All I did was that little plunger push and pull. I did want to force it open and mine seemed real tight. It's not in a real accessible place on a Z3. Few plunges and a few taps with a screwdriver and it's appears to be normal again. They should just put LUCAS labels on harnesses.

[@olivierlatorre9784]

Thank you! This trick worked perfect for me, the light hasn't been back on for the past 3 weeks. Just resit the plug and away it goes (I also cleared the codes with INPA).

Abs and dsc light on. Try pumping the brakes while driving along slowly, the on-board computer needs a certain amount of driving conditions to calculate before it can reset its self , All sensors need to b working .

[@DIYTEA]

It is better to clean all the plugs with contact cleaner spray. I mean the main control unit and both of the pressure sensors contacts. In other cases the brake fluid should be checked if it is older then two years, because if the amount of water raises it is bad for the sensors too. In my case I tried everything but finally I had to change both of the pressure sensors ( got them from the junk yard for some 30€). Now it is fixed!

Beware unplugging this could effect speedo or other electrical connections ( best to source the problem and fix it)

[@Anonymous-it5jw]

What you did had nothing to do with air bubbles, a stuck sensor or quality of the brake fluid. Most connectors need an application of dielectric grease to keep the contacts from corroding caused by vibration and/or moisture. Any small amount of corrosion is registered as a fault in the system connected to the corroded connection. By removing and replacing the connector you simply cleaned the corrosion off of the bad connection for a while, but, just as it did before, the problem will happen again and again, until you you put dielectric grease on the connections inside that connector to keep vibration and/or moisture from degrading the connection, and causing more corrosion and more problems. Look up “motion-triggered contact insufficiency” and/or “fretting corrosion” on Wikipedia and/or Google for an explanation. Or just look around KZbin for problems caused by bad electrical connections in modern computer-controlled vehicles.

[@eaglerider94]

I cleaned my module connection with electrical contact cleaner, blew it dry, reinstalled, and it worked. You are very correct about the corrosion issue with these tiny pins.

Good video, its nice to a see a basic re-seat fix a problem like that, I have few questions 1. I have those same lights but on my 2003 330i it is very intermittent. It re-sets every time I turn off the car sometimes it comes back sometimes it doesn't. But what I don't have is that ABS pump, what else could cause that errors on a car with out the ABS pump? 2. What model Scan tool is that? 3. What model head unit do you have and how do you like it? Thanks

[@ElbowgreaseDIY]

1.Wheel sensor,auto gearbox problems may do,do you have ELM with it? 2.Old Snap on Ethos 3.Nexus 7 (DIY) like it

[@Raptorman5174]

Thanks for the reply, My car is a 6 speed so auto is out. I keep hearing about the wheel sensors being dirty and to clean them. I can check my codes with OBD Fusion but it wont read those specific codes like your snap on can. I do like the Nexus 7 head unit very cool, I have an old D95 DYNAVIN that works well enough but the Bluetooth streaming audio is low compared to a CD, MP3disc or even the radio.

[@ElbowgreaseDIY]

Brake fluid level ok? Nexus dont have radio,streaming or CD but I've got satnav (tomtom) which works good,fast. If I want to add something I just paring my phone.For me it's enough,music,videos for kids and satnav.

I have the same problem. I tryed this trick but nothing. Appeared me on tester fault code 5e21 brake pressure sensor.

[@mateibogdan.27]

first you read the DTC error stored in memory. I had a problem with DSC error + hand brake light. I scaned with INPA and got a code like " Steering angle sensor Signal not plausible ... " I tested the steering sensor and it was reading correctly (left and right side). But the offset was at 5 degrees left. I remembered that i had one coil spring on back suspension broke at the bottom and the rear side of the car was not on straight position. I changed both coil springs and recoded the Steering angle offset with TOOL32 from INPA (i loaded the file dsc_mk60.***). Now, for 2 years i haven't had that error or dsc light on dashboard ! The idea is that the dsc +handbrake light can appear from some other problems, and without a DTC scan you cannot tell from where is the problem. Maybe you don't need to change any parts just a simple recalibration.

[@ewabeachhi.1051]

When it’s red, that means hand break is in the up position and the emergency break is engaged.When you release it into the down position you disengage the emergency break, which then the yellow “ break” light comes on is normal. Nothing wrong with your parking break or anything else to do with your breaks. Yeah it’s stupid..it’s the way bmw intended to let you know yellow “break” light means it’s in the driving position and red means it’s in parked position.

[@JonBoy1970]
