Sorry to hear about, Aussie X5.

Maybe it's worth to buy an extended warranty, I guess I will buy one sooner than later. I was quoted at a non-BMW dealer, where I bought the car, for AU$1500 at a dealer for Elite extended factory warranty, which is not from BMW. I didn't get it as I thought a BMW extended warranty would be better and BMW doesn't sell one as I didn't buy the car there. I am getting it now... although still not sure about the reputation of Elite warranty, guess it'll be better than nothing.

Anyone else knows Elite warranty?

my x5 before tinting the window the light upgrade, the diesel is a bit noisy but have got used to it. hate the exhaust smell

Aussie X5, I read your other posts about DP chip. Could it be caused by the chipping?

I am looking to get the DP chip and am convinced it will add noticeable performance improvement, but also worried about it bringing down reliability of engines or other parts as a by product.

How about HHO on x5 3.0d ?
Halp
I want to put in my x5 .
Posible ?

Mine 2002 3.0dA with 153 000 km just got out its inspection II last week, everything is allright except maybe the suspension wich start to be tired, I will change them for a full Bilstein kit this month.

Don't worry about a 70 000 km 3.0dA X5, it's just nearly new if you let it stock and fill the tank with a good quality diesel.

Chips Tuning is really hard for all the transmission because of the increase of torque, with the turbo because of pressure's increase and with the injection ramp because of the modification of the injection's time & pressure.

not me matey no chip in mine all bog stock

got the quote today 17000 dollars
and they did not check the crank sensor ahhhhhhhhg!!

I am gunna take a pill and lie down now before I kill some one

No these sensors work on wheel rotation not in the tyre as the tyre looses preasure it becomes smaller in diameter and this is picked up by the sensor as the car drives

It depends which system have You in Your car installed to monitor tires´ underinflation or total failure. If You have a RDC - Tire pressure monitoring system (it is what victor2002 meant) see this, then there is an electronic pressure sensor (#4) in each tire valve that sends over radio freq 433MHz a pressure value to the RDC control module (#1) using RDC RECEPTION ANTENNA (#2) for each wheel.

See user´s guide for information: If the inflation pressure has dropped significantly over a long period of time (which is normal for any tire), the indicator lamp will come on with a yellow lamp. If there is a tire failure with loss of pressure, the indicator lamp comes on with a red lamp.

If there is other system than RDC, it can use different way to get underinflation info but RDC definetely uses radio transmitters in each wheel valve.

Any other Aussie X5 3.0D owners who have experience with DP Chip? From what I have read in this forum on other threads (mostly dated in 2006), the performance improvements seem to be very attractive.

Can anyone tell me if the chip has been a reliable add in for the car as well? Many thanks in advance.

Not sure what the DP chip is but there is a firm in the u.k called superchips and lets just say the job they do in re-mapping the ecu has made a great difference, got a 3.0d 2004 e53 and it does move very well, considering they wiegh over 2 tonnes it is amazing. As long as you perform regular oil changes and use good quality stuff, then the engine should be able to tolerate the strain on it (superchips say they do extensive tests- I am sure they can jack up the bhp even more but would run risk of melting down engines!)

On a different note, does anyone know what colour coolant the diesels need?and if I can't go to bmw, is there any off the shelf stuff (mobil/texaco/esso that can actually be mixed safely with the orginal coolant in the car?just for top up purpsoses off course.

The tyre pressure warning system is sensed through the same sensors used fo anti-lock braking (ALB). If the computer sees a difference in wheel speed, it will activate the tyre pressure warning. This difference in wheel speed could be caused by an under inflated tyre (low pressure causes reduced circumference and wheel turns faster in relation to others), it can also be caused by aquaplaning. The wheels will turn at different speeds when the car aquaplanes and the low tyre pressure warning will sense this difference and set the warning light.
The last set of tyres I had (Bridgestone Turanzas) were not too good at clearing water from under the tyres, and I experienced some aquaplaning. Can't remember if it put the TPW light on though.
Another side effect of aquaplaning is the effect it can have on the cruise control. CC also uses the ALB sensors for speed control. If you aquaplane with the CC engaged, the computer will sense the wheel speed reducing and pour in more diesel to regain the desired speed. This could be a little disconcerting seeing the speed decreasing and the rev's increasing.
If your problem only occurs in the wet, I would suspect aquaplaning and not a real fault.
Colin.

Yup I agree, I only gopt the warning when I had a fat nail in the tires, 3 times!
