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

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.

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

      You have your numbers back to front. 350mm from wheel centre to guard lip would be scrapinly low and the suspension arms would be at spastic angles and it would have the road manners of a meth affected giraffe. You can down to ~450mm (from larger stock starting values about 50ish mm higher than that) before you start to create to many problems.

      I think last I checked it was 35cm from fender to wheel center. I heard u can go up to 45-48cm before handling his impacted. But I need to check again. I know I was about 1.2 cm off being close to max recommended.

      You'd need to weld on an external gate to achieve that number though. I can't remember seeing anyone make 500hp at the wheels with the stock manifold / internally gated turbo.

      Pillowball/Hardened Runner Hybrid Approach

      By TmZer0 · Posted

      Suspension Component Question Looking for some feedback based on people's experiences! I know this has been loosely covered in other threads but I can't find any direct answers/experience. I'm up for some bush/rod replacements and was interested in a hybrid approach between hardened rubber and pillowball kit. Why not choose one or the other? Well, this is for my daily driver, which I track once or twice a year. I like a stiff car and a sporty feel but I don't want to compromise the chassis too much with 100% pillowball gadgetry.  I know from experience and a tonne of reading that not all components affect ride quality in the same way - eg. in my case, coilover top mounts should be hardened rubber as pillowball transfers way too many undesirable qualities and doesn't have much more upside than a good hardened rubber. But, pillowball tension rods translate to much better turn-in/steering response and make the car significantly sharper, without negatively impacting ride quality in a significant way.  I'm not TOO bothered by NVH (to a degree). So, with context out of the way, does anyone have any experience with a hybrid approach as mentioned above? I'm going to replace all components over time so am seeking guidance on: - front tension rods - upper camber arms - rear lower control arm - rear traction rod - rear upper camber arm - rear toe adjuster rod  Secondly, is there any reason why this is a bad idea? Or any other info/wisdom that I might not be considering. Cheers 🫶

      That's good to hear I'll stick with the stock I hear they are good for 500hp and I'm only shooting for 350-400 once I can get this thing sorted and get to actually building it.
