greetings to all

how can I tell if the sls is working on my 16v? Had the car idling and loaded the trunk. Nothing self-leveled! Is there a problem or am I just not understanding how the system actually works?

Yellow warning triangle lights up when wheels spin. Does this mean that asd is ok or are the two not related? (asd light goes out after ignition)

What are the best lubricants to use in this car's engine, auto gearbox, diff, hydraulics, cooling system?

Have a roughish idle with some hesitance on pull-off. Also have some oil in my air filter housing. Sounds tappety too. Any ideas?

Quiet a bit to chew on, I know. Give it a shot. It will be greatly appreciated!

Thank you
