Some random questions

[BigLion]

Hi guy's,
PDC sensor volume can only be adjusted via Diagnostic tool (GT1) in %.

Heeyyy - Shak you beautiful genius.... I will see if I can access this option :)

Headlamp wash wipe will only work with headlights on and a flick of the washwipe. It will only work once unless you recycle the headlight switch.
One common problem is the headlamp wash pump internalls get rusted,by removing and bashing it couple of times normally does the trick

Worked for my other washer pumps (fore and aft) but in this case I have found the problem now - water hose was blocked so I used the ADNOC air hose to clean it - still nothing happened after I sparked the motor with 12V and reassembled the tank - so, as one would suspect, when I broke open the barrel of the pump, I found that all the parts of the impeller are shattered. Seems like when the flow stops, the motor kept turning and broke the propeller into pieces :(

Here's another fine mess... it underlines the comment we made before - look after the car and it will look after you! (including checking the hoses)

I was poking around the car today while getting it polished; just wondered...

1. Is there any way to alter the volume on the parking sensor speaker? It's too flipping loud, that beeping!
   never heard of anyone trying to lower the volume worth having someone shed some light on this
   
2. How does the 'special wash' work for the headlight sprayers? I don't think mine have been working - the owners' manual mentions something about 'they only work if the car thinks the headlamps are dirty' :please:
   
   They work when your headlights are on and when you spray water from your wingsheild wiper lever
3. One of the polishing guys said there was a nut loose on the back of the diff' in the rear axle - is that possible/ relevant/ a problem?
   the best way to know is to have it checked because it is simply not safe... bolts and nuts do losen up with time
   
4. What should the correct tyre pressures be - I don't have the plate inside the drivers' door with the information.. I read 32 PSI front, 34 PSI back from tyre-pressures.com - sounds a bit low for the 315/40 R 20s on the back?

(all relating to the 2006 X5 4.8iS :D)

35 PSI all around

Thanks for your help, o sleepless ones

Today I am driving with 36f and 40r and the ride seems pretty fine.

[BigLion]

...on the X5 it's a different story. 38PSI or above is what I recommend because it is a 20 inch rim after all and the tires are very low profile, therefore the higher pressure keeps the tire from deforming under load or bumps and bending the rim. Your manual should say what tire pressure you should run.

I have tried from 34 to 40 PSI an all corners; with 34 you can feel kind of an inertia - the run feels 'flabby' so I thought this was too low; 40 was definitely too high as the car felt bouncy and the steering was way too light. I guess with low profile tyres the pressure is more critical as it seems to affect the ride sensation much more - I will go with 36F and 38R by comparison of all the other pressures... just wondering if this was way wrong!

[SHkater]

As far as the parking sensor volume, maby you could control the speaker input with a volume control switch. Just a thought.

About tire pressure. Shkater, dude! 39PSI on the rears ?!?! That's TOO HIGH! 32PSI tops, 34PSI if you're going to load up the car and trunk with a crap load of weight. He's only running 17's. But, on the X5 it's a different story. 38PSI or above is what I recommend because it is a 20 inch rim after all and the tires are very low profile, therefore the higher pressure keeps the tire from deforming under load or bumps and bending the rim. Your manual should say what tire pressure you should run.

Thats according to the side sticker dude

Nice idea! If I can find a dedicated wire I could put a potentiometer on it :D

[BigLion]

this what i thought:
2. mine in the E60 worked only if the headlight swithed on by pressing the wiper switch.

4. did you check the owner manual?

2 - I think they still don't work with the main wiper action, even with the lights on; it says somethng about 'at appropriate intervals' the headlamps will be washed when the main wipers are used with [stalk position] 5 - have never seen water on them or the lamps or bumper so I am assuming they don't work :( - I will try to spark the sprayer motor with a 12V supply to see what happens

The owners' manual is awesome - I didn't know there is a trick to set the interval of the rear wash-wipe!


4 - Unfortunately I am in catch-22 here cos the OM says 'check the plate inside the drivers' door', but there isn't one!

This tyre pressure thing is very confusing. The manual suggests pretty high air pressure but Ayham suggests otherwise.

The manual for my car says 36F and 40R. But I keep 34 all round. Now am I going to destroy my rims or what.

Regarding the tyre pressure, I think thats way low because my dad keeps his rears at 39 Psi and front at 34 Psi and he's running 235/45R17 and thats according to the sticker on the Drivers door
