Hi there,

If you've had your vehicle computer codes read and determined no issue with the VSC circuit, then you just need to cancel the warning light.

I've made up the following instructions, on how to clear VSC & TRAC Warning lights:



Zero Point Calibration of Yaw Rate and Deceleration Sensors Using Paper Clips (or jumper wires).

First, locate the 16-pin ODB II connector under the steering wheel (beneath the dash). The pins are numbered sequentially backwards from right to left (from the wide side of the connector looking at it from underneath).


Take two normal-sized paper clips (or suitable jumper wires). If using paper clips, straighten one edge of one of the paper clips. For the other, bend it open to a 90-degree angle (like an elbow).


Insert one paper clip/wire into pin # 14 (Ts), and the other paper clip/wire into pin # 4 (CG) of the OBD II connector - DO NOT allow the paper clips/wires to make contact at this point.
Refer to diagram below:

1. Ensure the shift lever is in "P" range.


2. Turn the ignition switch to "ON" (not start).


3. Momentarily touch the two paper clips/wires together (short) and separate again (open) - Repeat this process 5 times (within 8 seconds of turning ignition on).

Verify that the VSC indicator light is illuminated, indicating the Recorded Zero point is erased.


4. Turn the ignition switch "OFF".


5. Remove both paper clips/jumper wires from the OBD II connector.


6. Turn the ignition switch "ON" (not start) - wait until VSC warning light turns off (approx. 20 seconds), then wait 2 seconds.


7. Turn the ignition switch "OFF".


9. Re-insert paper clips/jumper wires to terminals #4 & #14 of the OBD II connector (as per above diagram).


10. Turn the ignition switch "ON" (not start) - VSC warning light should remain illuminated for 4 seconds, then start flashing at 0.13 second intervals.


12. After VSC warning light flashes for 2 seconds, turn the ignition switch "OFF".


13. Remove paper clips/jumper wires from the OBD II connector.



Drive your vehicle to confirm VSC & TRAC warning lights have been reset and no longer illuminate.

Remove the internal handle and I think 1 or 2 screws and lift inside door panel off, pull the latch and it will open!!

I assume its a petrol version ,,Now first thing is check out O2 sensors with a voltmeter ,undo plug in turn and check for 12v feed with ignition on ,this will be two wires the same colour normally white ,now check for continuety on the sensor end of the plug .Now if this checks then reconnect the plug using a small pin push through the wire to gain contact and start engine and check voltages ,should run between 0.120 to 750 as engine is revved .if no reading or it stays the same normally around 700 then renew .Use universal ones around 50euros each These must be working correctly or the symptoms are exactly as you describe .You cannot remove the catalyitic converters as this means the vehicle will be poluting the atmosphere also it will not pass the annual vehicle inspection .Also yes the throttle position can cause similar problems plus a few other things as well .If you are not capable of this sort of work then use a local mechanic to check it out for you.

Until the fault is fixed it won't stay reset. Once the fault is fixed it should go off on its own
