A6 Allroad 2013 suspension on the floor

[Audi dan]

Evening all

The Allroad has an issue with it's suspension.

It's slammed in the floor for no reason today and I need to find the location of the fuse and relay for the compressor 

I can't hear anything running 

I've replaced an airbag last year due to a broken rear headlight level sensor and was wondering would another one cause all 4 corners to drop?

Regards

I'd say a faulty compressor. I'd recommend a diagnostic check to see if any fault codes flag up

Thanks I'll get codes read tmrw

I'll also check the relay although I've never known relays to go.

It's in the rear right wheel arch I believe.

Please keep us posted on how you get on 🙂

Will do... hopefully something simple.

I will check the other 3 headlight level sensor arms aswell.

Hi all

I had the codes read to this morning and it says an air leak.

I can't hear one although the compressor isn't running.

Would the compressor turn off due to an air leak?

What if it's the compressor at fault?

Where's the relay for the compressor?

Kind regards 

Dan

Think I may buy a new compressor..any good places to purchase from?

Thought it'd be the compressor 

[Audi dan]

Me too....

Hello Dan,

’Thinking it may be’ the compressor maybe a costly assumption, since it appears, an assumption it is. 
Where to get one ( if it is)? 
Refer to my post of 18 hours ago. 
Kind regards,

Gareth.

Hi Gareth I've emailed Andy with my info a D waiting for his reply 

I'll go over the car before coming to a firm conclusion.

Dan

I'll keep you posted.

Dan...hoping it's something simple

Thanks Dan,

Well worth checking you have 12v at the compressor before coming to any decision.

Kind regards,

Gareth.

Ok so I've looked at all bags and no obvious tears. Unfortunately as there is no air at all can't check for leaks.

I'll get under the car soon and check for lower etc but the relay and fuse which I believe are for the pump have tested fine..

Hopefully it's the pump and or power issues.

The reason why I think it's the pump as I had residual air in the air tank in the boot for a day or two and no leaks were heard.

Anyway I'll keep you posted.

I haven't had a reply from bag pipe Andy.

Is there a number for him?

Sorry Dan, always dealt with him through eBay and messages. 
Kind regards,

Gareth.

Once you have restored pressure a good test for leaks is to paint or spray soapy water on all components watching for bubbles.

I'll get under the car once the weather is more forgiving.

Ok so the codes were mainly level codes which I expected but there was two an overheating code and a code for a leak on or near the acumilater?
