Just to share.

Have been confused to why the steering would slightly go off centre while driving even though wheels has been aligned for couple of times and showing good results on the alignment deck at the indy shop.

After months of reading here and there, just come to realise my steering angle sensor reading was not exactly zero when the steering wheel is physically centre.

After recalibration of the sensor, then re-alignment of wheels, now steering wheel is good centered when driving.

Why this happened? Just come to remember that dealer might have the sensor re-calibrated during my Riyadh visit last year. I had a problem on the DSC/Active Steering showing no 4x4 which relate to the torque sensor on the Transfer Case.

Oh well, at least this one now sorted. Now, time to look at that possible leak on the valley pan

Car:
2007 4.8 with active steering.
