G'day Guys,
I would like to temporary remove the bottom dash on my MY02 D110 - the part with the AC as I want to install some more insulation for sound and heat in the footwells and firewall - see Insulation post also.
Anyone know how I can remove the AC section - I know there are basically only 5 screws holding the plastic section on, but the AC plumbing goes through the firewall and through the plastic matting I am trying to remove and upgrade.
It only need to be off for a couple of days while I do the work - whats the correct way to remove and plug up the AC?
THX in advance for any ideas

Yeah mate thought so - was rather hoping there was a on/off valve in the engine bay to aid the removal???

As mentioned above, the system must be 'de-commissioned' by a qualified ref/ac engineer.
The R134a refrigerant needs to be recovered into a dedicated recovery cylinder.
However, if the guys does the right thing, after you put it all back, in theory he can put 'your' gas back in to the system - he may have to add a few extra grams - but he shouldn't charge you for a full gas charge - just the labour and the extra few grams.
when you take the bits apart - make sure you seal the ends of all the pipes - preferably with a rubber or plastic bungs, dont be tempeted to use sticky tape direct over the pipes.
R134a runs with a very hygroscopic lubricant, and if you get too much moisture in there no amount of system vacuuming/decompression will remove it, and the lubricant will emulsify - and root the compressor.
This is especially so in warm/hot weather with high humid conditions.
