@UCnnOF7jC3IWYD6st86OSTqg my problem is that my car is showing parking brake error where as i checked my parking brake motors both side are working fine my tyres do not stuck when i remove parking brake
I have the same problem but can not get the vent trim piece to come off. There are locks described on left and right sides but I don’t see how to release the lock.
You can contact nearest Mercedes Benz dealer, they can give you , From 2021 they give the option for repair kit , Now I I don’t have remembered part no ,
For A/C vent removing use two small screwdriver 🪛 and one Celeste’s tool for pull out With the use of screwdriver 🪛 you can unlock hook 🪝 press both lock inside like one lock left side pressed one lock right side pressed the pull a/c vent out I hoop you will do your best,
kindly help me my cla 45 amg is showing parking brake error both motors are working scanner says front left side abs sensor and check engine light from ecu says backside left rpm sensor it was checked through mercedes tool scanner and thru xentry so they cleaned my abs sensor in front and back again error cane as i drove my car then to confirm if abs sensor is ok they interchanged left abs senor to right side and then right side sensor to left side again error came when car was moved fast what could be the fault help me that day from that workshop i came back these errors came once and they went away on their own and didnt came back for months this workshop said due to closing time the day i went there mercedes technician told me he has to check the wiring and hub of the wheel maybe rat bit the wires i washed my car parking brakes got sticked it happened three four times when i was not able to drive much after washing the day i went to workshop brakes were sticked because i washed my car three days back when i applied little force they opened with a noice and errors went away but as i opened my door at fuel station those errors came again im unable to understand what could be the fault kindly help me so that i can solve it myself
I understand 1st ABS light on, 2nd rear parking brake moter stuck, 3rd engine light on , These are the problems after washing the car, Tips no1 , Remove the battery terminals And wait Tips no 2 May be water or moisture inside of wiring connectors or ESP connector unit , Clean with pressure air , So clean with water make dry , Before checking the wiring check actual valve of wheel speed sensor with scanning tool, You can drive the car on 2post life , Or while driving the car on the road you can check, 2nd check 12v power supply on wheel speed sensor with multimeter, Cause of abs light 1st wheel speed sensor 2nd wheel bearing 3rd any wiring damage 4th control unit
@@mercedessportcarrepair1944 tip no 1 i already did it removed the battry terminals for atleast a day but fault code didn't went away gave ecu time to refresh but it went in vain no benefit in this case
when we cleared the fault codes during test drive when i accelerate tyres revolve then these errors are coming back the day i went to that service centre i was already late so they only checked abs sensors cleaned them nothing happened and then changed their location to check if problem is elsewhere not in abs sensor they made it sure because right abs sensor fitted to left side again it showed those same fault codes they cleaned abs sensors and the position where it goes inside both left front and back sensors were cleaned sprayed but nothing changed and my car is aslo showing service due message too but currently it has been driven 6500 kilometre after last service on 8500 kilometre its service was done i drove it 6000 kms now car is at 14000 kms this 45 amg is 2015 manufactured registered in 2017 could it be the case of faulty auxiliary battry scanning tool didn't showed any battry problem till now maybe due to seven years time both battries must be old...il check tomorrow one by one as you said lets see if anything positive comes out of it thanks for replying i dont want to ruin your sleep so i am very much obliged that you replied back once again thanks a lot...motor is working fine i checked it my tyres revolve after i pull it back i removed only one terminal and unplugged the ecu should i unplug both terminals tomorrow and check once again
@@fhhvdhuhhvhdvuhvdvh IF You have already try battery terminal remove but problem is still , then if you have pressure air so make dry near ESP control unit area you can use sunlight , if pressure air Not available , other easy way we are unsinging petrol (FULE ) For removing moisture , but not safe visually inspect underbody or Engine compartment any mouse bitten , Use scanner tool Xentry Diagnosis follow fault code guide test ,
