d4 lowering options

[nath]

has anyone lowered there vehicle and if so how ?

i have found 2 differant options

1 via installing adjustable links which tricks the suspension into thinking its actually higher than it should be and releasing air to get the correct ride height

2, via a seperate plug in module which after fitting allows you to alter ride height and suspension settings

any info appreciated

cheers

The d4 is an unknown animal to me but from what I have read the principles are the same as the other Audis with air suspension so assuming rosstech have figured out how to talk to the level control Ecu one ought to be able to run a calibration and trick the car into lowering it self.

Have you got vcds?

I did look at this and found these ...fleabay item number 121217899414
I believe its just swapping the links on the suspension sensors
Haven't bothered to date for fear of the loveable dealers voiding the warranty for something.

I'd personally try lowering links first before playing with vcds. Pretty easy to fit and fairly cheap to achieve your chosen height.

[nath]

yes i do have vcds
however i have read a couple of things that lead me to believe the d4 is not as simple to change via vcds than the d3
apparently theres a code needed to get into the module and alter any settings

i am going to shoot over a request to ross tech and see if they can give some guidance on the issue

ive read a little more about the adjuster links and it sounds like the car simply deflates the bags to achieve the correct ride height
the problem with this is the ride afterwards is not very good

[Delboy]

All the methods for lowering air suspension are done by dropping air from the struts, if it was me I would go vcds if you want cheap, lowering module if your feeing like a bit of retail therapy and last but not least the lowering links as that requires jacking the car up removing the old links and no end of ****ing around trying to adjust them once fitted.

juat my thoughts on the matter

[nath]

just tried vcds and you definitely need security access
to alter any of the settings

[Delboy]

Certainly worth asking Ross tech support about it.

Did you get any response from rosstech on this?

I failed at the security code on Rosstech website. says invalid when entered.

[nath]

sent a question to the ross tech guys
never recived an answer but got an invite to join there forums

[TTE Si]

I got the same response, After waiting near a week and sending logs. I think more just to know if I had a genuine cable.. I did.

I ended up buying the lowering links too drop mine. But not ideal for veroius reasons.

[nath]

in all honesty im loathe to buy lowering links
for fear of destroying the very comfortable ride

I'm happy with the ride hight. Just very dissatisfied with the lift on it, but then it's not true air suspension like the D3 it's kind of a hybrid between DRC with air assisted lift ...

Wish I could programme it to have serious off road capabilities in lift mode as I did with my D3 for the winter in Germany! But alas the lift remains a poor 20mm lift for rough roads not snow ploughing.

In my D3 dynamic was low, auto was 20mm lift, comfort was a further 20mm, and lift was a further 50mm fully maxing out the struts. This of course was for extreme conditions. In Germany it was great in the woodland where our cabin was.

Wish I could do that on the D4 but altering the Driver select seems to have no affect on ride hight in the D4.
