Hi,

I finished changing the fluids on the 4wd system.

Now when I give it a little the engine warning light comes on. Drive it sedately and no problems.

Any ideas what causes this?

Oil changed within 5000Km, plenty there.

My wifes driving up to Bundy a 600Km drive on Friday, so hopefully sort it by then.

Cheers,

Brendan

Hi Brendan, didn't you get a consult cable? could check the error codes with some consult software. There is a way to check the dtc's by shorting 2 pins on the consult plug and have it flash the error code with the check engine light, i think there is a procedure in the workshop manual for this.

Hey mate I have the same problem as well! I found it goes away as soon as you touch the throttle again. Oxygen sensor maybe? How many kms have you done?

Yes I was going to say 02 sensor, when mine went the engine light would come on when idling at lights, as soon as u got going it would switch off again so yeah check your sensor

Thanks

I was thinking maybe the FWD part wasn't 100% before, now the fluids are ok its' working harder?

My wife reckons she hasn't seen the light any more.

Yeah i'll look into it.

Good tips.

Ours does the same, give it a bit and she'll come one back off and after a little bit it turns off, been like that easily 6 months now though. It was also hesitating or running rough like there was a coil pack issue, but only during summer - now that it's winter its not doing it.... does this sound like it's coil packs for sure?

How many kms have you guys got with this problem? I have 98xxx km on the clock

We all know the coil packs go around the ~100k area so I suspect mine are in their way out because of the heat?

Note my coil pack cover is off so the hot air doesn't get traped

      But seriously, can we ask for the results of the "tip a bottle of metho into a nearly empty tank" experiment?

      Hang on. Let me get this straight. The desire is to have coilovers, BC in particular, to be MORE comfortable on Sydney roads than stock suspension? Well, that's obviously not right. BCs have crude damping design at the very best, and typically hard spring rates. BC stands for Billy Cart. And then, the desire is to put in some shitty old worn out stockers, to get it blue slipped and then put the BCs back in? And then.....what? Not worry about getting pulled up by the Plod? Because you seem to have raised a worry about paying for engineering (which actually does solve all your legality problems) and still getting pulled up.... but the only problem there is that if/when that happens you have to show your paperwork at the inspection station. Whereas, if you just swap in borrowed shitty old stockers to get it slipped now, and then you get defected in the future, you have to go find more shitty old stockers then too. You course of action looks like this set of options: Buy brand new stock type dampers, and springs. probably cost a bit more than $1k all up, but will last for the remaining life of the car. Put them in, pass inspection, drive on them forever more. Hell, they could even be really nice Bilsteins and Kings or other lower&stiffer springs if you wanted. Get the car engineered as is. ~$1k. Buy new Shockworks coilvers (or MCA) and also pay for engineering. You're spending a lot more here. But these will be the best things that you could drive around on.

      Might be worthwhile hitting up Facebook's groups, I know most of them contain terrible people and scammers - however you might be able to find someone that's in Sydney with factory suspension you could purchase and/or hire. Just do not send any form of money anywhere, in person cash only.

      Thanks @Duncan Ride height is fine. I think it's almost stock tbh. Happy to share a pic. I don't actually have a regular mechanic as haven't lived in Sydney too long. Could you or anyone recommend any shops in Sydney?
