Just an update to my problem, driving home today and was testing a vibrate in the exhaust at high revs so changing at around 7-8k, then i noticed the awd light turn off, jump in the next day and light is on again, so back to the usal problem, then jumping in and staring the car this arvo the awd light flickered on and of realyl quick with a buzzing comming from the ATTESA pump in the, last about 5sec.
Had a quick chat to my mechanic and he sed its one of the solinoids (sp)? whats are they?
