Hi all
Well after I got my XC90 2003 back from the Garage after a service I was informed about the faulty Steering Rack ?
Say what ...Well after driving petrol cars all my life I just assumed that this BIG XC90 and DIESEL engine being heavy was the norm ....
Nope as the mechanic pointed out to me that it should be nice and light ..
But long story short few days ago went back in to sort out the main culprit and the worse case Scenario would be the Power steering rack at
£700 + ...Ahhh
Thud ...faint how much ...blimey ... but as soon as he gets 5 minutes he would have a little look at steering and rack and pump
NOW BE WARNED THERE IS POSSIBLE 2 TYPES OF PUMPS AND RACKS
So find out what you have ..
Any way about 2hrs after dropping off the beast I got a phone call and good news its not the rack or Pump ..
its the...Get ready ...
Power Steering Rack Speed Sensitive unit ...say what
yep mine is fitted or has the Power Steering Rack Speed Sensitive..HOW DO YOU KNOW THAT
simple lift bonnet and look for this
NOTE NOT THE PLUG below red circle and little bit of wire ...this is brake ABS plug
If you see this plug then this is where the Solenoid plugs into off the rack as in below picture
Ok so now you know what rack you have
So to test out the wiring etc. if you not into electrics then LEAVE WELL ALONE
but open drivers door remove drivers fuse box lid look ...check Fuse 16 this is to the servotronic RELAY and maybe others so where how do we test this theory
Well My Mechanic disconnected the plug labeled No2 and I'm Guessing applied 12v ( sorry was not watching ) and he said try the steering now ...
Holly C**P ...mega Light
and I mean light so Now waiting for a relay to turn up and replace it but if your having same problems then heres an idea to do and test
The Servotronic relay is located under a panel of drivers footwell so remove the two torx screws and look under neath and you will see this
NOTE NUMBER
30658312
I cannot stress this enough there is a few different ones out there with different numbers ..MORE PINS on the relay so make sure every number match's
and now some info for the likes of me you GEEKS out there is a flow chart of the POWER STEERING......
ENJOY
