Range Rover sport help please.

Hi all. I have a 55 plate sport which was disguingly filthy so took it for a valet. Now when I went to pick it up it would t start. There was loads of water under the front footwells so thought the worse. I told the Valeters I came in driving and want to drive it out. They denied any responsibility at first but then agreed to take the front seats out and dry it out. Now it will start, but not all the time. The glow plug light dosnt always come one. When it does star it won’t idle. As long as it’s revved up it will run, but as soon as I
Take my foot of the gas it will cut out. There has never been a problem like
This before I took it for the valet. Can someone please point me in the right direction as to what’s wrong. Obviously water , but where has it got into. Any help
Would be really appreciated. Thanks.

I would guess they used a steam cleaner on it. Electronics do not like steam cleaners. In law they are liable for the damage. With a dehumidifier in it, the electronics may dry out and recover but I would not count on it. Worst case could be a write off as the cost of fixing it may be uneconomic.
It's up to the valeting company to fix it, but I would bet it would need court action to get them to comply and they probably have exclusions in their T&C's about this sort of thing.

A "Valeting company" that doesn't understand the correct way to clean a vehicle?
It beggars belief really. Sorry for the OP's experience.
I always wonder at the chaps you see in the supermarket car park washing cars.
Do I want the sponge that's been dropped on the ground 5 times a day rubbed in circles all over my paintwork? - I think not.

If they won't accept responsibility, only one way to go.Get it fixed by a garage that knows what they're doing. Then take valeters to court.
Lesson of the day, don't give your pride and joy to a valeter, unless, you know for certain that they are capable.
Second lesson of day , don't allow your vehicle to become "disgustingly filthy".

once the electrics are that wet damage is done to repair it will be more than the car costs plus it will play up for ever i would say. you need a replace the car.

Get a dehumidifier in it and keep it running with the doors shut until the tray doesnt need emptying. Take as .such carpet as you can out, particularly the footwell ones as they are usually thick foam backed and act like a sponge.

I bought a 928 that had sat in Ireland for a couple of years and it had pools of water in the footwells. let the carpets dry out dried it all out inside never a problem
The footwells hold water as the lowest point and it's unlikely there will be wiring across the footwell.

What you need to do is make sure it's dried out before moist air seeps in to electronics

If a steam cleaner was used, the electronics will be full of condensation.

How bizarre to take a steam lance/wand to the inside of a vehicle. Just how bloody dirty was it?
Where's the before & after pictures?

I'm afraid valeters commonly use steam cleaners in interiors, there have been a number of disasters reported here on LZ

Oh my goodness! I had no idea they could be so dumb. I guess it is all about speed of clean and depth of clean and no thought for the ancillary electronics.
What a shame for the OP.
