My mates busy working so I thought I'd post about his issue. Maybe get some pointers for him to try.

He picked up an MY00 WRX (not bugeye) on Monday, 111k on it. I believe it has the EJ205 motor. We checked everything you would normally check on the test drive. Been fine all week. But today he took it for a long drive up the coast - check engine light. Pulls over and apparently it appears there isn't much coolant - middle of nowhere so he puts water in it to get him home. The Check Engine goes away.

I went over and checked it out. Engine sounds fine, a little more aggressive than my B4, but overall - fine to me. We started it in the driveway and there was no light. It doesn't appear to be leaking and didn't overheat... Oil doesn't appear milky either (oil level is fine). He got it from a dealer so they are helping him out, taking it to Subaru tomorrow. Guessing they'll plug in a computer and checkout whats happening and of course drain and replace the coolant.

Do you know what codes it's throwing man? Could be anything at all.

I've had my check engine light on for 2 days now, because my car is in limp mode due to a lack of speed sensor. True story.

Cheers,
Shazza

Haven't heard from him, but when he finds out I'll post what it was. Apparently comes and goes.

[XXB4XX]

it's a faulty sensor guaranteed.. picking up a false / bad reading somewhere.

if it's a little rough on idle, more than likely the AFM or an 02 sensor somewhere.. exhaust ones are common

This thread needs more error code readings.

[Adam]

Code 32, and 14

Here you go Alex.

It was the knock sensor. They reckon the previous owner was running it on RON95, and now that he is running RON98, it might have had a hiccup on his first long drive in it.

Also the clutch is failing in 3rd, mechanic noticed a slight slip and we tested it ourselves. Might have triggered the knock sensor too, if it jumped in the revs. So he is getting quotes on a new clutch now - which is a shame. I guess if it is the original clutch, they usually fail around 120k don't they?

Correct. 100-130k kms is a good run.

New clutch kit.

Don't bother with HD. No need.

Also, don't forget to change the rear main seal. Some people will say "if it ain't broke, don't try to fix it".

I like to say "swallow a chainsaw you kent, its called preventative maintenance"

haha Chainsaws.

I replaced clutch at 112-113 on my Prezal. Just with OEM. Saw it today when bro dropped by, it's still going strong at 160. Preventative maintenance is the shizzle, and NEVER assume cos he bought it from a dealership that it's all good.

[TSG]

Yeah a Subaru dealership quoted him $1500 to do it, screw that. He is going to ring around and get quotes.

And yeah it isn't covered under the 'warranty' so they can go to hell. I've been in it again since, the clutch does bite, we had it in second on a roundabout and when you give it a bit, and go up to third on the exit you can feel the slip. So its not terrible, but is 'on its way out'. Other than that the mechanics haven't had anything else to say about it.

[Alex]

I'd want to replace it at your next available convenience.

Only because the clutch isn't fully engaging, and you can potentially cause dramas with gears engaging.

Average price for a clutch replacement is $1200-$1400.

Make sure you don't get stung with TT tax. Yes. I got charged more for mine, (quoted $1200, then upon pickup, $1400). I asked why the increase in price. I was told that because my car was a TT, it involved more work.

I asked what was the difference between single turbo and TT in terms of clutch replacement... "You have to take the Y pipe off the exhaust"

Thank you Nick, NRG Automotive @ Rydalmere. CNUTS.

So if they try charging you more, pay it, and set fire to his shop.

[TSG]

It is going in for the clutch/service as soon as he has the money. It has been in his garage for about a month now. Was quoted $1050 at one of the better mechanics here, to get the clutch sorted - we think this is reasonable.

We investigated some more, and it does have a rough idle, and will actually start pinging slightly once it warms up. Subaru recommended a decarbonisation - but I have told him it might need a tune. The first time I have ever heard a car ping, now I understand the sound! It is running on BP Ultimate, so something is definitely not right, and the check engine isn't lying. Hopefully he can get it sorted soon, pizza doesn't pay well...

[Jimbo]

I dont think a tune will fix it.

Get a can of Subaru upper engine cleaner, smash that through and then take off the AFM and hose that sucker down with some AFM cleaner (Supercrap, Rortobarn or Ripco). If not already done, get that knock sensor sorted, if its naffed it the thing will pull timing or miss picking up knock and blow the engine to smitherines. The latter is probably unlikely as when a knock sensor fault occurs, the engine defends itself by pulling timing and being a homo.

My money is on the AFM if thats kicked the bucket or dirty, your mixtures will fail at life, and be a root of the detonation hes experiencing. Also, when he hits detonation, make sure he gets the welly off the juice button or he'll turn a big end into terminator toothpaste.

Also, if your low on engine coolant juice, it wont show up a CEL. Thats what the temp guage is for
