Thread: Suspension Fault Normal Height Only

Noken, can you work out what the cost of this Zmax inductive service actually was ?Sounds like someone else out ozzy park way has worked out how to rip you off.
remove and replace air intake duct and decarbonize, yeah ? Ill bet they did !!!!!!

Zmax induction service $51.66 labour, "induction kit" $44. I believe Zmax is American product similar to Seafoam that was used in Subaru WRX 's to clean induction system. UK D3 site seemed to conclude this Zmax was being done across UK in D4 3.0 diesels at annual service. The dealer also added fuel conditioner - $15.25. Some owners were wondering if the use of Zmax was to ensure long happy turbo life?

Well, after a short day doing some mild off road driving, my D3 has the dreaded 'Normal height only' message. I have tried all of the 'quick fixes' as outlined in this thread ie: lockup car, disconnect battery etc, all to no avail. I can only assume that the compressor has carked it. This is the second compressor since new. The first going at approx 80,000km (3yr) mark, now at 160,000km (6yr mark) another seems to be the problem. You would think that LR would rectify this problem. My biggest problem is gaining access to the compressor. I have fitted Rover Speciality rock sliders which weigh a ton, and are very awkward to remove and refit. Can the compressor be fitted in a different location? Has anyone tried? Where is the filter located, can this be readily accessed or is it fitted at the compressor site? Have also thought of fitting an after market compressor, but this seems to be a bad idea due to the high pressures required by the system.

Hi Turtle146,
Your compressor enclosure might be full of dirt and mud so you need to check that first. You should really get the codes checked rather than assume the compressor is failing and perhaps this would be a good time to purchase code reader. Even if it is the compressor unit, the dessicant in the dryer might only need restoring by drying in a microwave or oven or even purchase a new dryer if the old one is clogged, which costs pocket money compared with a new compressor assembly. There's also available a compressor outlet valve kit if the valve is worn-out.

Without rocksliders, the dryer can be removed without removing the whole assemby.

Mine is doing this same thing. Had it to the dealer before xmas, and due to staff leaving and trashing paperwork, they had reallocated my loan vehicle the day before - for 2 days - and they couldn't do the car all day.

They did read the fault codes, reset the computer, and clean out the filter in the system, however they said it probably wasn't that.

Now one thing I've noticed is that now that the humid/wet weather is finished for a bit, the fault has stopped. Seems a little strange.

When it was happening every time I used the car, I did find one thing that worked. If I left the car at 'normal' height, the fault did not happen. Dropping the access height, and driving off, it would happen in a minute or less.

Car is off the the dealer for a day or so on Thursday. Research says it's either of two issues mostly: Software that can be updated or the compressor itself. Will report back after I get the car back.

Hi Graeme
Where can I get a good code reader, and will it reset the service codes?
I take it the dryer is located along side the compressor. I daresay I will find it all once I remove the LH rock slider. Once the compressor is exposed, is there anything I should be replacing / upgrading (other than the compressor)?

Below is a link to an thread in disco3 with lots of pictures with regards to rebuilding the compressor and finding and fixing up the air dryer.

Re a fault code reader, the best and most expensive ones are the Faultmate units per the link below. The Faultmate FCR is cheaper but does read and cancel fault codes. The full meal deal MSV-2 does what the dealer can do and more.

I found the link below, (but all in German), and if I understand it correctly, the guy running the site sells parts for the D3 compressor, and more significantly, little bags of the desiccant.
