The alternator packed up on my 08 tdv8 which i changed ,since then the power steering has got heavy,no leaks or anything,the rest of the car is fine ,is it a software issue ,all the dealers want me to book it in but i am not prepared to do that ,dont like their prices .

Check the air suspension module for fault codes relating to the sensor on the steering rack

That, or the lower UJ is seizing up

Thanks for that,where is the module located?

The air suspension control module is on the a-pillar up behind the dash on the driver's side. It's accessed from the footwell relatively easily.

When he says "check the module for fault codes" that means sticking a suitable reader in the OBD port. 2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed
