    Default When the engine is out, what should you replace/upgrade?

    I've been told that this is what you should replace when the engine is out, since it is a nightmare to do it otherwise if they break:

    - Knock sensor
    - Ignition coils

    I consider upgraded head gasket and head bolts (1,5 bar boost / 325 hp), but have no good motivation since I haven't had any problems with them. Pistons will be replaced, but what about connecting rods?

    Anything else?

    Last year when the clutch was changed we planned to take the engine out, but the the guys at the workshop (?) has done the clutch change without the engine work, so it was an easier job in the end
    Nevetherless they still removed and sent the steering rack to a refurbish company and completely dismantled the transmission and central diff. Bear in mind the guy who done the later is a transmission expert, our Q4 requires a veteran for that

    Ooooh. That was an advice that really took the breath out of me ... Mine has done just under 100.000 km, so I suppose it is kind of low mileage, it has done two transmission oil changes and been standing since January 2009. 5:th gear has been changed as well once, for a longer one. But I am curious, what did steering rack and transmission components look like? Were they worn? Did it improve feeling, sound/noise, or anything after the overhaul? In any case, it are quite big jobs to do - all respect to your workshop!

    The steering rack was leaking oil since years, very small amount but still leaking and I had to refill the steering servo oil from time to time but otherwise it was ok. During the refurbish they changed all the bits and peaces apart from the original housing and rack. Since there wasnt any big knocking sound issue before I do not feel or hear any major improvement, apart from that I dont have to refill the servo oil

    The transmission got a humming noise whenever the car was in gear and I did not accelerated so we wanted check that. During the oil change we saw too many metal pieces in the worn oil, which isnt the best thing so the oil change quickly expanded to a transmission inspection after dismantling. Since our transmission is built in with the central diff it was as pretty big job and if I remember correctly some bearings and maybe a gear had to change. It works much quieter now!

    All in all the car was in the workshop for almost a month, in the "project-car" garage, so it wont interfere the daily jobs and the guys who worked on it were given a bottle of fine whiskey, each 'cause it was indeed a big project
