Despite this I recently forget when I tanked it round a little roundabout on the red light and 10m or so out of the roundabout I got the worst case of surge to date The car violently cut out and I could actually hear the metallic clinking sound of the stalled engine making several revolutions against the drag of the drivetrain She fired up when the juice returned and I continued on cursing myself for having forgotten.
SB, for heavens sake, do you never take anything on board Do you sit at home and whip yourself for fun?
Is masochism a hobby?
My question is this: Is there something wrong with my car?
Some people never learn

Well, I for one have never ever had fuel surge, even when thrashing it below 1/4 tank. I don't drive along roads with slow, sharp bends - say 40-50mph is about the tightest.
I do tend to flick the car before the bend to get a little oversteer or nice 4-wheel slide, so it does get chucked about alot.
Really don't know what to suggest

40-50mph
Burr, I raised this: apparently its to do with the fuel 'surging' away from the pick-up in the tank! I perfer the term 'fuel starvation'

I've not had it on a bend but accelerating hard in a straight line(gtir),the engine cuts out as if you've stalled,nearly throwing you through the windscreen,then restarts again.
I think Powerstation sell a fuel swirl pot which should ensure a constant supply of petrol or fit a longer pickup on your pump.

Before you all start this is a serious thread/question...
I got fuel surge again today....BUT....at just over 1/2 (yes half ) a tank Better yet I was 'making progress' but wasn't going anywhere near as fast round the corners as the car is capable of. I'd have described my driving as 'cruise and squirt'
Since the imfamous fuel surge spin I've been the butt of many a joke but I still maintain to myself and my closest scoobynet friends that it was the biggest contributing factor (well the fact I was cornering hard to cause it in the first place was, but that's beside the point). I really can't be arsed (as I'm sure you can't) debating this so lets not go there. Anyway, since then I've always been ultra-cautious with fuel surge and don't push the car when less than a 1/4 of a tank or if I really have to have some fun then I'll only take on the left-handers at speed. Despite this I recently forget when I tanked it round a little roundabout on the red light and 10m or so out of the roundabout I got the worst case of surge to date The car violently cut out and I could actually hear the metallic clinking sound of the stalled engine making several revolutions against the drag of the drivetrain She fired up when the juice returned and I continued on cursing myself for having forgotten.
Today's event was far less violent and a lot more like the 'bogging down' that most people describe fuel surge as There was no doubt in my mind it was fuel surge though despite the vast quantities of fuel on board (it can't have been an ECU boost cut as the dawes calls the shots unless it hits fuel cut) The corner was a 90 degree countryside jobbie - 60mph road - and I really didn't go round that hard! No sliding or tyre squeel?
My question is this: Is there something wrong with my car? Does it appear to suffer fuel surge worse than others? There have been a few reported cases of half tank surge under extreme track conditions but surely it shouldn't happen on an average country jaunt? Could the cars state of tune (1.2 bar dawes and tek2.5) be making it worse. Is the fuel pump or something else in the fuel system goosed or overstretched? All sensible suggestions and opinions welcome
Granted I've taken a while to get to my point but you'll apprecaite if I had said, 'I got fuel surge, what's wrong with my car' it would be the start of WW3 or perhaps 4 depending on what happens in Iraq

Admittedly my Scoob is a bit older than yours (MY96) but I have never had a "fuel surge" problem, even with it nearly running on the fumes in the bottom of the tank.
I don't know whether the design of the tank, fuel pump & fuel lines etc. changed for the later cars... I know the injector rails changed...
You start to think about Occam's razor at this point...

LOL @ diablo's short answer of 'some people never learn' followed by a '**** it I'll wade in and give him hell edit'
The spin was about 5 months ago so your damn right I wasn't driving around today with about with HALF, in case you missed that 'HALF' a tank of fuel thinking, 'oh, better be careful, might get fuel surge' Not to be expected really unless your driving like a bat out of hell.
For the record the fuel guage seems to be fine - I get about 300 miles to a tank from full to vapour and with good representation of the levels throughout.

Don't know m8 to be honest.
Like I said, I've never worried about fuel levels (within reason) when driving hard. OK, I'm no Michael Schumacher but I've had the car sideways a tyre squaling round corners plenty of times and never had this.

Kenny - despite thinking you were being an idiot about the cause when you first posted about your 'off' it occured for the first time to me yesterday that your 'fuel surge' incident COULD actually have been the cause of your spin if your problem was far worse than as 'standard'.
I'm no mechanic, but the 'normal' Impreza fuel surge just wouldn't cause what you described, so I'd suggest you have a genuine fault.
PS keep it smooth

I'm wondering what your oil level reading is?
If it's at the top mark or slightly over it could be that in extreme cases the oil is going above the crank and getting behind the pistons on one side. This can cause similar sounding symptoms. If your oil level is high, try draining it to around 3/4 full mark (or slightly less), repeat situation and see if the symptoms reoccur.
All the best

Half a tank, is your in tank fuel filter blocked?
I used to occassionaly get "fuel surge" on my wagon, but only when the light was on and really pushing it round a left hander.
Since fitting an uprated fuel pump with the original filter (sits lower in the tank) i have never had it.

Cheers Ozzy, you learn something new every day
I recall someone saying that most 'track users' get some sort of sump baffle as the oil sloshing around causes the ECU to panic and go into 'safe mode' Surely this can't happen with me though because of the Dawes. As far as I'm aware all my ECU can do now is pull the 'fuel plug' if it overboosts for 3-4 seconds (can't of been this as I didn't floor it for that long and there was no sign of overboost). By razors law (you like ) that leaves fueling or something completely different.

Occums razor: "The simplist solution is probably the right one."
I use this to justify throwing dirty plates away.... its simpler than washing up. You can (almost) use this argument seriously if you are a scientist.
FUEL PUMP. It does sit on the right hand side of the tank ergo, fuel "surges" away from it on right handers.

Goodwin's law:
Can also apply to the word's "Saxo Boy" and "Fuel surge" when uttered in a thread. In this case Goodwin's law was invoked pre-emptively. If I were a psychology major, I'd watch this thread like a hawk.
Professor Goodwin, U of I, in 1981 made the observation that Usenet discussions gravitate downhill.
He postulated that as the length of a discussion thread grows, the probability approaches one (1) that one participant will introduce the terms "Hitler" or "****".
The custom has evolved that the first party to utter "Hitler" or "****" has lost the discussion, and the thread terminates.

Sopunds like you're car does have a problem if it is that persistant and obvious.
Cant you get a STI super-dooper-anti-surge thing that you fit to the tank or something?
Or an uprated fuel pump?
If it was happening that much i wouldnt be just waiting for it to happen again (so i could post on here about it and get a ripping ) i'd be doing something about it......

I have experienced fuel surge in my MY00 around 4 times on the road in just less than a year of ownership. Always when cornering hard to the right and usually with less than 1/4 of a tank. I have experienced it (or the symptoms) once with half a tank.

i never has fuel surge by the time of ur infamous post.
but about a month ago, pushed it a bit far on a 90 deg right hander... with < 1/4 tank.. BIG fuel surge
havent been anywhere near it again.. tho am now scared of them.
perhaps once u have had it - something alters in the state of the fueling system that causes it to be able to happen more easily again?

i confess i had it once on a near empty tank going round a roundabout very slow (by the kenny standards lol) & dont go that low again but anyway duz sound more extreme so if i were u i'd definately wana try a few extra goodies 2 try & avoid it as already mentioned better fuel pump is a cunning plan on most scooby's from my (limited) understanding especially if u start 2 seek more power
Duz sound like u have sumin that wants tweaking/improving thou!
Si (technical numpty but can spot the obvious)

Did some checking mate and came up with this for you to try
Ok Ok....... so it's for a boat, but I doubt the North Sea pitches boats around as much as your braking pitches your car into corners
PMSL at my self
This thread must not die, it's like Comic Relief........
