    - Sunroof frame badly rusted

    - Front lower wishbone rear bushes need replacing (advisory on last couple of MOTs)

    - Alloy wheels badly corroded (debating forking out for full refurb)

    - Rear door windows laminate / glazing failure (the white clouding at the base of both)

     

    Sunroof frame is rusted on mine too, and o/s rear window cloudy.

    Luckily the w/bone bushes have been replaced and the wheels look suspiciously clean so I'd say they have already been refurbished too.

  2. Still all good on the suspension front, I may as well move on to the next issue, there is quite a list.

    Steering wheel doesn't move.

    Sat nav dvd player.

    Rear shelf sub woofer.

    Exterior lock button on the drivers door.

    Front parking sensor.

    O/S headlight squirtie.

    A/C leak.

    Maybe a very slight leak from one of the exhaust manifolds, only noticeable from outside the car.

     

    I'll probably look at the steering wheel first, if it were your car what order would you tackle the jobs in?

  3. No longer required as I've just purchased the one linked to above, I did pop into my local main dealer but they wanted over £500 instead of the £274.88 I've just paid.

    Fingers crossed, A, that it turns up and B, that it fixes the suspension issue...

    That's the beastie. :thumbup:

    Yep, and today after closer inspection I have found this part to be leaking from the plastic housing, caused by it's metal bracket corroding.

    The shock still has valves inside.  There has to be valves inside to allow air to escape/ be replenished.  

    The shock is a sealed unit filled with oil, there maybe some electrical magic added to adjust the firmness.

    The 'spring' is the airbag which is controlled by the valves I linked to above, they are mounted externally and adjust the amount of pressure in each bag accordingly.

  5. I've just had a closer look at the rear distribution valve and it is leaking very slightly, from where the plastic is in contact with the (corroding) metal bracket.

    They have the part on fleabay but I don't really want to spend almost £300 just to then uncover another issue with the suspension...

    The output from the suspension compressor must have a multiplex valve system that pressurises each shock according to the info it receives from the level sensors. I very much doubt that they will be individual valves unless they are in the strut itself, which is a possibility.

    As I mentioned above, there is a unit under the rear of the car, near the diff.

    This has two valves on it that, I guess, control the amount of air going to the struts.

    Edit:- Just found the unit online.

    With regards to the air suspension, to save a headache, take it out and replace it with decent coilovers 

    I've been looking at BC coilovers for £787.55 but don't want to ruin the ride, I would rather try and find where ever the leak is coming from and keep the car standard.

    ....no under or oversteer....

     

    Why did I waste all those years driving tin cans?

    Fortiswick old boy, you simply aren't trying hard enough.

    Seriously though I think it's always a good idea to find out the limits of a new car, that way you have more of an idea of how it will handle if you ever need to take emergency avoiding action.

    What car did you have before the RX?

    I've always been a Vauxhall man, Cavalier CDX, Vectra 'B' CDX, and I've just kicked the Omega habit, I had somewhere between 20 to 30 of them....

     

    Anyway, I hope you are able to enjoy your new car for many more years to come.

    Cheers,

    Rich.

    If the air struts are okay, then it could be the rear height sensors at fault

    The rear suspension does inflate when the engine is started, the system also reacts to the different modes as selected from the dash switches, it just deflates at the rear within 5-10 minutes of switching off.

    On another note I had the a/c re-gassed today and the man only wanted to put in 650g, I mentioned that I had read it should be closer to 950 for cars with rear a/c and he checked another source to confirm! He also said that his machine had recovered no gas from my car so I guess there maybe a leak from somewhere, although for now it's blowing icy cold.

  10. I also had a close look at the strut it's self and sprayed soapy water everywhere, no obvious sign of a leak.

     

    The following picture shows the archliner, there are 5, 10 m.m. nuts that are hard to see, three across the front edge and two on the top, you can see the big circles in the sound absorbing pad...
