DSC and Flat Tire Lights came On

[naseem80]

Dear Pro's

I dont know why when i leave my car parked for sometime (2 weeks to 1 month), she welcomes me with a problem..as she is angry and sad from me..

previous time i left her about 2 weeks,SMG yellow led came ON, and everything was normal..SHAK replaced the Relay, everything went fine..

This time, she welcomed me with DSC coming ON..here is the details..

the first few seconds you move the car, you will see DSC lights blinking (as if you are drifting), if you push the brakes, you will hear Cracking sound. then the DSC light will go ON, the first place you will stop (Signal light)..the Flat tire will come ON...

I have read on the internet, to find many people facing the same problem, and they are saying that Flat Tire light ON due to SMG malfunction.

Many mentioned about the Speed Sensor…

Last point: once I had replaced a sensor called: ABS, Pulse Generator senor, part Number: 34521164652..is that the Speed sensor???


Waiting your comments about what may be the cause, and how I should rectify it

Thanks

yup! speed sensor it is :).... most probably :)

[naseem80]

where is the speed sensor location? can you give me the part number?

[Bruno]

the dsc is blinks on and off?! or it stays lit?

[naseem80]

the first few seconds it Blinks On and Off (as if you are drifting)..then it Lit On all the time..

make sure you level the tire pressure first, reset the module from the button on your console. then drive again. if it blinks again then as wazif said.

But tell me, where is the speed sensor located..and what is the part number..

[Wazif]

[Wazif]

if it is a wheel sensor it should affect ABS, and throw a warning "ABS" light but i donot think it is a wheel sensor
i think it is some loose connection
the cracking sound can be due to brakes getting rusty from long parking and should not cause an issue with DSC

Updates:
Dear mates;
i drove yesterday my car to AGMC for inspection, and here was the result: there is a sensor installed under the drivers' seat, called Speed Rotation Sensor, Part Number:34526754289..this should be replaced...

firstly, i felt very happy for the news...a sensor and will be replaced..but the bad news was: the sensor price !!!!!! It will cost you 3000 AED (without discount), and when i called Sentral, they offered for 1850 AED..

I thought of checking the used BMW's, i might be lucky to find one...Unfortunetly, i couldnt find, as this sensor only installed in any 6 Cylinders E46, but the car should be equipped with DSC (Not ASC)..i searched all available, the result was negative...

I used the REALOEM website to check abt the part, and i got to know that this part also installed in the Z3 and Z3M...

Any one can help me?

Naseem, bro im checking the part for you, need another day to give you a reply, wait until tomorrow..

[Wazif]

Suggest you take the car to Shak.... before making a decision to change the sensor
