Got back to my house tonight and caution light comes on and steering making a whoore of a noise.lucky for me i was just parking up.....Opened the bonnet and there is hydraulic fuild everywhere after cleaning it up the leak is coming from a cross shaped stud on top of the pump tried to tighten it up to see if that would help but only helped a little ..what i am needing to know if it is o ring seal below stud that has gone .......and if anybody here has ETKA Cat for the diagraim of pump which with a bit of luck should show me were the seals are situated

Cheers

I take it the steering pump will be the same on my S4 as it is on S2?

If you have a 2.2 liter turbo ABY engine, I would be surprised if there was a difference... But I'm no expert...

Just got ETKA CAT and seems the same...............what Hydraulic Fluid should i put in?

what Hydraulic Fluid should i put in?

Only use the VAG green mineral fluid, part number G00 200 0 or as everyone calls it G00 2000.
Can be had from VW and Audi dealers and also from GSF.
DON'T put red ATF fluid in, or it'll rot seals.

Cheers Guys .....parts coming tomorrow

One more thing bleeding the pump after filling back up i take it there is only the +bolt that i am replacing that will bleed the system?

Cheers

You shouldn't lose that much fluid, and it's self bleeding anyway. Just top up and do a couple of lock to locks.
