Thread: D3 Air suspension conversion to coil

Most of the time a restart, or a hard reset disconnecting the battery and shorting the cables together will fix things (must be done in the correct way.....car goes to sleep, disconnect battery terminals, short terminal cables with a spanner, etc ensuring that the battery is not touched. Reconnect positive first then negative)

If not you need the Emergency air up kit from Green Oval experience.

Brett.....

If it goes down to access height then that's "safe" height due to any fault broadcast by the ABS ecu. If its a permanent fault such as caused by a broken wheel speed sensor wire then the vehicle can be raised by either Llams or using shorter (eg GOE) rods. The emergency air-up kit is necessary mostly only if the compressor has expired.

Not sure if anyone click on the link, but with this conversion all the TRs etc still work as you get an orange box to pug in.

Yes I read it. That's how I managed to quote some of the text. I'm not sure you understand exactly what the Terrain Response actually does and how it integrates with the air suspension though. So the Terrain Response cannot fully work when part of it's normal function has been removed. When the D3 detects that it is stuck, it will raise the suspension to extended mode, and then super extended mode to clear the obstacle. A bit difficult to do that with coils.

Look at it this way, if the coil sprung version was so good, they would outsell the air sprung version. Don't see that happening!

Something else worth considering, I recall reading somewhere that if yours is a 7 seat model, then you would need to get the change engineered as a 7 seat coiler is not type approved.

I read it as well and have just had another look. I agree with Sheerluck, the TR and air suspension are tightly integrated. And work well. If you are particularly worried I would look at the Green Oval Experience emergency air up kit. This will handle the problem of compressor failure, airline leaks or problems with the reservoir tank.
The air bags are to quote GOE's web page "the airbags themselves are almost never at fault - we have never heard of anyone "bursting" a bag, as they are severely over-engineered".


The other thing I have reservations about with the coil conversion, is that it does not state what sort of height is attained. As far as I am aware (and I may be wrong - someone will let me know) D3 coilers need a lift to get to off road height equivalent. So you could (probably would) find yourself with a much less capable vehicle.


Just my 2 cents worth

Cheers Guys
I found a link to GEO last night on this site and I will be spending some $$s with him.
Thanks for the info.

Repairs to air suspension can be cheap, 12 dollars for a compressor repair kit, new valve, sprig and O ring, not 1200 dollars as quoted by independent.
Replaced front valve block 20 pounds ebay uk (car was sinking).
As for bush repairs, not so confident.
First post, sorry if amateur

Welcome to the forum Spuds.

You are correct about finding cheap alternatives, however it is typically bush repairs that people get upset with.
