I've recently had a non start issue on the 350 shown in this thread: viewtopic.php?f=10&t=
To cut a long story short it was a problem with the IDPM unit, but before the dealer diagnosed this they stripped the dash completely and removed the BCM & ECU.
The car now starts but has gone straight back into the dealer as the steering is now vibrating on its own - almost like it cant find its center and is hunting.
The dealer put the car up on the ramp and with the wheels free from the floor the steering rack will start vibrating with the wheels & steering wheel bouncing back and forth. There is no play between the wheels/rack or steering wheel
He checked the PS pump & lines and no leaks were there, pressure is ok, and the pump is working fine, no noises etc. They touched nothing under the bonnet while doing the repair and i've never had a single vibration while driving the car in the past.
The fault has got to be electrical caused by something they have done while removing the dash.
Is there anything electrical which will cause the steering to act up - almost as if it dosn't know where to center?
Appreciate your time reading this.
Thanks Andy
