What a ride - suspension nose-down

Not sure if this will help, but might be worth a shot. It's a seller from Gemany selling the struts. I would contact the seller and see if they can send them internationally. I know that A8 Parts send parts to all over the world, so give them a call too. However, I agree, you should be ok replacing just one strut. Also I would maybe call around a few other Euro car specialists, just to get an idea of pricing and to see if any of them have dealt with A8's before.

You might have to clear any fault codes with Vagcom or similar before the suspension starts working

Just heard from the techs, they say it's that sensor control block. He's going to let me see if I can find a better price on it than what he can get from Audi.

Waited a week to get the control valve in the mail, and it doesn't seem to have solved the problem.

They installed the new control valve, and "some of the codes are gone" but it "still doesn't know to send air to the 4 corners".

So they are trying to track down any broken wires between the valve and the control module, if they don't find any then I guess we replace the control module?

Does it sound like these guys know what they are doing?

I've read how some parts need to be somehow "configured" with the car's computer, is this one of them; and did they miss that step?

I've asked them to send me the codes so I can post them here.

what do you think?

After replacing the control valve, and finding no leaks, they have contacted me saying they have only one trouble code - and of course the car won;t lift a millimeter.

01575 - Controller Switched off.

But they don't know what to do. The service manager actually offered to pay for transporting it to the Audi dealer

I told him I would check the internet

I'm about to go do some searching, but wanted to post it here first. Has anyone seen this code, fixed it?

thanks!

The question is what and why have switched it off.

It is a long shot but if the car has not been used for a while battery might be getting flat and power control switched some systems including suspension controller off to conserve energy. You can try running engine for a while to let the battery charge up or charge it off the car and then tell the car you have put new one in.

Might also check fuses and wiring connections.

Other then that I am out of ideas.

I got this advice from an online source:
" I have seen that the battery went dead so the abs light / trac control light and the suspension light would be on and disabled. in order the suspension to reactivate the car must be driven in a straight line for at least 100 feet to relearn the steering angle sensor . once that has relearned the trac light would go off and the suspension light would go off. then the suspension would be active again. I do realize that the suspension in the front is low. the electrics battery MUST be fully charged or new battery is needed. This battery is a special AGM battery and the same must be used if replaced.
please try the test drive 100 feet until the lights turn off in the dash and then clear the suspension fault and then see if the air will go to the front struts"
also this:
"if the battery in the trunk is not charged correctly the battery will cook and render no good. if the battery is 2yrs old and older chances are that the battery will not take a full charge with the proper charger. that battery is a Glass Mat battery and can not take charging voltage over 14.3 volts."
