Pressure washing any engine bay is not a good idea these days, too many electronics that can be damaged by water especially at high pressure.
Hopefully it will dry out on it's own, if not keep your fingers crossed that your dealer is sympathetic.

ok let say the special program was off so on what mode It was sand, grass..ect? the different types of terrain was off cetral round swith not lighting and when I select any program says fault..still the car moves..that means there is any by pass for all logic and the car select nomal mode maybe..I just guessing. low gear was flashing, the hight selection indication was flashing too.. 2007 Range Rover Sport Supercharged, Buckingham Blue, Ivory converted to HST Silver

If water is in the ecu's / sensors nothing will make sense

Twice, after washing with high pressure hose, one of the horns went kaput.
Luckily, both times were at the dealers... so free replacement! Malaysia Boleh!

Not what you want to hear, sportman, but as Cliff says - not a good idea to pressure wash the engine bay In your climate, it should all dry out nicely unless there's been any physical damage to any of the electronics. Good luck

Agree Sportman, the RRS should be able to deal with a moderate amount of under bonnet water ingress, it is after all an off road vehicle as well, i know that you have to be very careful when pressure washing under the bonnets of modern cars, but come on you would expect the RRS to be able to handle it.

Agree with Envoy that it should be able to handle moderate water ingress - as you say sportman it is after all designed for off-road use / crossing water - but that is quite different to opening the lid and jet blasting / steam cleaning the insides. I can't think of many off road conditions that involve pressure hoses and steam cleaning, apart from maybe an erupting geyser - which no doubt LR would say was in breach of warranty!

Having said this, it's not uncommon for certain dealers (I can think of an unnamed BMW dealer in particular) to give the insides a quick blast with the jet hose post-service.

Glad it worked out for the best Sportman.
