I have just gotten off of the phone with Subaru UK.

The UK STI 8 IC spray is a fully manual spray system.

If you fit any part to your car that does not have a Subaru part number it will void your warrenty. Therefore if you fit a switch that will convert the IC Spray it into automatic operation it will void your warrenty.

Sammyh, if you can get me the part number that makes the IC Spray automatic I will get it ordered and fitted.

Just to say that above link is for test of an aussie MY02 STI.

sammyh,

You do know the article you posted was an article on the STI7 don't you?

I've got an STI8 and the only time I hear the spray working is when I press the button.

Edited to say jhrfc1 got there before me.

I have just managed to get through to the technical department at Subaru UK. At first they didn't believe me that it is manual so they have done some investigation for me. It would appear that we are the only country in the world with a manual system and they think it is done to save costs.

They agree that fitting an automatic system would improve reliablity and performance and so there is no technical reason to not fit an automatic system. The problem is that it requires a non standard part to be fitted and that part has to be plugged into the ECU thus voiding the warrenty.

I have been advised to write to the Technical Service Manager at Subaru UK, I have his full details but wont publish them here, and find out why it is not an autmatic system and also to try and get approval to fit an automatic system without voiding the warrenty.

Apparently the warrenty issue rests with him as he has the final say on all warrenty claims.

It occurs to me that if enough people write in and make this request something may happen. If anyone wants to give this a try then mail me and I will send you the relevant postal details.

I have a hot seat fitted to my scoob, and this requires some new wiring, this has not voided the warranty ?? so why would this mod cause such concern as it will prolong the life of the veichle not shorten it, this surely would be an added bonus

revitt

You have to plug it into the ECU, if that fails no warrantee

Just had a reply from Mike Wood at Prodrive who states it is AUTOMATIC.

He spent yesterday at Knockhill and used 2 bottle fulls during the day (and he only pressed the manual switch twice, once with his knee by accident

Hope that this now settles the argument (bet it does'nt thou )

cheers simon (STI8 with auto i/c spray)

Call Subaru Technical, they will give you the correct answer.

revitt

Simo:- can you tell me if Mike Wood is driving a UK spec car of an import.

If the UK car is supposed to be automatic then my car has a fault that should be fixed under warrenty as it does not use any water, but every one I have spoken to at Subaru insist that is manual and therefor won't fix it.

I have sent a letter to the Technical Service Manager at Subaru UK with a stamped self addressed envelope requesting clarification on this and I now await his reply. Once I have it I will post the response.

I don't doubt it you when you say your car uses water and is therefor automatic, but unless Subaru UK come around to that view point I can't get my car fixed.

AFAIK all STi *TYPE UK* cars have a manual only IC water spray. My STi7 certainly has a manual only system. The dealer told me this when I bought it. It only uses water when you press the button. When the tank is half or less full, the light comes on under hard acceleration giving the *impression* that something is happening. THIS IS AN ILLUSION. All that is happening is that all the water is sloshing to the back of the tank, making the water level sensor think the tank is empty. That's why the light comes on. It is just telling you to put more water in the tank. That's all.

You want to move to Wales....decided not to use the water spray on mine...but then its usually pi$$ing down here

scoobycar60

My STI7PPP gets through water as I regularily have to fill the tank up. If this is manual only then where's the water going?, I never bother to use the manual switch so its not going that way.

ProperCharlie

scoobycar - that's an interesting question. It seems highly unlikely that some cars would be manual and some auto - although with subaru I suppose nothing's impossible. One answer might be that it is just leaking out on some people's cars. After all, the system is made of the same stuff that the window washers are made from, and the water has to travel all the way from the boot to the bonnet - must be quite a fedw joints along the way that could leak...

On my car I have got thru' *one* tank of water in over 20k miles, and that was purely from pressing the button in moments of extreme boredom

MikeWood

Gentlemen

Lets sort this once and for all. Unless we have a leak on all the UK demo STi's we've had the system works automatically with a manual over-ride. If your car isn't using any water then it's because the various parameters for automatic operation aren't being met.

End?

Mike

ProperCharlie

Well I respect Mike Wood's superior knowledge here, but if that really is the case then I hate to think what I'd have to do to get the auto system triggered on my car

philgr

Thanks for trying to sort this out Mike!!

Could you please let us know what the conditions that are required to activate the water spray, ie boost pressure against outside temp etc.... and are these conditions modified as part of the PPP conversion

Thanks in advance

I think the 8's is automatic with a manual button as well. I use maine quite hard, and it uses water quite frequently. Lets face it, if you are nailing it, the last place you want to fumble around is the manual switch.

Scenario: flat 1st, 2nd, where the hell is the spray button (near my right knee somewhere) 70mph, grovel, fumble, take right hand off wheel to press switch, eyes glance down to locate switch, left hand off wheel to change gear, corner, oh poo. I've gone off.

Its comes on automatically.

johnfelstead

Does that mean the USDM STi is auto also, the USA guys think its just manual.

Why not turn the nozzel 180 deg, then you'll see the spray over the top of the scoop (just remembered that it's an awfully big scoop) maybe.

You have to give the car death in order for it to activate. If you drive like a ***** it wont be needed, otherwise you would need a 40 gallon reservoir in the boot.

Sammy - How are they modified?

In the mapping I would imagine

ARRON BIRD

I **** my car all the time.
I push the button a lot at the moment and only have for the last month really bit and the light has only just come on and I`ve had it 8 months??
I`d like to know what the parameters are too.
Does it have to be 30 degrees???
I dont think its auto on mine but there you go.What the **** do I know
When I push the button I can hear( or could hear before I fitted that Firestorm back box) a slight supression noise from my stereo.
I dont hear that when I`m ******* it and not pushing the button!!!???At the moment I am struggling to hear anything

I have to agree with Andy. You must all be driving like ****** (with exception to Arron )

Seriusly thou, you have to drive the car bl**dy hard to make the i/c activate, if you are low on water and the i/c light comes on, you will see how hard. Why not empty some water out and give it as try .

cheers simon

simo we have already revealed why the i/c water spray light comes on when the tank isn't full. it *does not* mean that the spary is coming on automatically.

revitt

I am afraid that Mike Wood is incorrect. Following is an extract from a letter sent to me by the General Manager - Technical Services Subaru (UK) Limited on official Subaru Letter Headed paper.

This is an unambiguous statement and clearly states that the UK STI has a manual system, it also implies that all STIs around the world also have a manual system, but as mine is a UK model I don't really care what is fitted in other countries. The letter goes on to list the risk associated with fitting a non standard automatic system and I have therefore decided not to fit an after market modification.

I will be fitting PPP in the next month or so and so If, as Mike Wood insists, the UK demo STi's all use water. Is this a feature of PPP or do they all have a leak or do they have a feature that is not available to the general public.

As I stated earlier if you can show me documentation stating that the intercooler spray is automatic on current UK STIs then please let me have a copy and I can get my car booked in for a warrenty repair.

I don't doubt that other peoples STIs are using intercooler spray water, they may even have automatic operation. BUT I want a warrented automatic IC operation in my UK STI 8 and Subaru UK have issued a statement saying that it is a designed manual system and have given me the reason why.

I would love someone to give me documented evidence that the system should be automatic but unless they can then I have to accept that it is a manual system and live with it.

Sorry to go rambling on, but the original question was did anyone know why the system was now manual, most responses have been that it is not manual but actually automatic. I have now gotten a response to my original question from Subaru UK and I hope that that is now the end of the matter, unless anyone can prove otherwise.

cue a phonecall from Prodrive to IM. LOL

The easiest way to prove this is to get hold of a wiring diagram and see if the ECU has a wire to the IC spray relay. If it does it can then be monitored, if it doesnt there is no posibility of an IC auto spray function.
