Right rear

Right front
Left front.

When doing the rear, make sure the suspension is at loaded level. This can be done in a number of ways. Otherwise, enough fluid won't reach the caliper.

Re: Q4 Viscomatic hoses (hydraulic lines)

Opening up this thread again. Had to make new hoses for Viscomatic on one of my Q4;s recently. I actually made them of AN lines and fittings. Used AN4 teflon hoses for everything. The Teflon AN hoses has a pressure rating of 275 bar, so they`re more than well suited for the job. Finding the correct...

Re: Q4 awd warning light on instrument cluster. HELP

The tester socket for the AWD is also right next to the ECU. Passenger side in the centre console, remove cover and you should see the ECU with VISCOMATIC written on it. From there, you can follow a short cable which is a 3- pin connector, which the tester connects to. Ask if you want pictures of an...

Re: Q4 awd warning light on instrument cluster. HELP

mm... If the light never goes out after self check, that reduces the possible faults significantly. Can be worth it to check in Alfabb.com / alfaowner.com, if anyone has a tester to loan/rent to you. The tester makes life just much more easy. What you need is the Magneti Marelli tester, MA12-A modul...

Re: Q4 awd warning light on instrument cluster. HELP

If you would put the car on a lift with NON-functioning AWD the rear wheels will still turn if drive is on. The question is that does the Viscous coupling engage or not. If you don't feel comfortable with electronic diagnostic tools, now is a great time to learn! :wink: When you turn the key in the ...

Re: How to empty the power steering/Viscomatic hydraulic system

Flush the system. I did so a couple of times when changing from ATF to more suitable fluid for the colder climate in Finland. A couple of months after the fluid change, I had to rebuild all the pipes, due to the supply hose being rusty and started leaking. There was no sign of ATF in the system, onl...

Can you verify that the AWD does NOT work when the light is on? I have had the light come up a couple of times, but the AWD works even though the light is on. The reason for the light coming up a couple of times was the steering angle sensor having a poor connection. There's a couple of ways to veri...
