Hi all, hope someone may have some insight or had a similar issue. Bought my VFII SV6 Auto Sedan brand new in March 2016. So far have done 18,000km. Since December 2016 I've had non stop ongoing issues with; Driving along fine from cold start, get to set of lights etc and upon trying to take...

how many litres are you putting in when you say full tnak. the gauge/warning migth say "EMPTY" but you may only be able to squeeze 55 or so litres in (its a 75 litre tank) as the gauge is notoriously crap. mine is accuracte until about 1/3 remaining then it goes bonkers. so thats why it "seems"...

ideally you would bleed Rear pass side, rear driver side, front pass side then front driver side so as to go from the longest line to the shortest... its most effective.

If you said the wheels lock up early thats nothing to do with the brakes, you need better tyres.

are you able to tune the motor of SV6's, calais' etc, without touching the box?

Likely the battery then, when it detects its a low voltage it shuts down non-essential items (eg. ABS)

The 4 speed really didnt like downshifts at WOT (eg, floor the pedal and it would kick down to 2nd) as the 2-4 band would wear out quite quickly (thats why a lot of of the 4spds have a harsh upshift and delay/flaring on downshift) also the 3/4 clutches would wear out often. BUT that being said...

Regarding the braking, most likely either your pads or rotors need replacing/machining (if the rotors are significantly worn they cant' be machined they will need to be replaced) OR also a possibility, but less likely, is that you have busted a radius rod bush or two and the wheel is being able...

my radiator cap failed resulting in overheating engine, i replaced it then couple of months later the water pump also failed, this is common as the cooling system (or any system, auto trans etc) is only as good as its weakest part.

if you have killed 2 tranny's in a short space of time and the symptom is burnt/overheating oil, certainly look towards the ATF cooling system.....

The accelerator on a VZ is completely different to previous models as it is an electronic one, ie. no cable, it has a sensor to tell the computer how far down you've pressed it, therefore you need the specific VZ one like here : GENUINE VZ HSV/HBD FLY BY WIRE ALLOY PEDAL SUIT V-6 (eBay item...

I know what you mean.... IMO, they should be checking for things like radiator hoses getting old/worn out, and certainly a quick test drive (transmission about to fail? bad need of wheel alignment?) that some car owners may not pick up on..... Some mechanics are certainly more thorough... for...

contact GSL rallysport (forum sponsor) for a better quote on the parts....

Radiator caps are rated to a certain pressure which it will hold pressure too until it allows the coolant to expand into the expansion tank. If the radiator cap cant hold pressure (or you just simply take it off) the car will almost certainly overheat straight away as the system wont be able to...

yes the paddles are a bit ordinary (lag much) but it does it in drive too when putting foot down a bit further when in 5th at light throttle with the torque converter locked up (the converter slipping or struggling to unlock maybe???) so its not just a characteristic of the dodgy A/S mode

i have this same problem too - in active select in 5th the revs bounce up and down (almost like the converter is locking and unlocking the common problem in the old 4L60e's) and in drive, if im cruising in fifth and accelerate a little bit more (like to go up a hill) it does the same thing -...

I have a Gregory's VZ one which covers Vt thru VZ. Its not very good, for eg it covers V6 AND V8 ... so its not very specific....

Is the thermo fan coming on when necessary. Also possibly a stuck shut thermostat?

has your k & n air filter oiled up the MAF causing a lean mixture and less power.

Is it actually using that much fuel or is just the guage inaccurate, (measure it by filling to the top, doing 100kms or so, filling it up to the top again, calculate how much fuel it used to do that 100km and get a l/100km figure). I agree check the area around the fuel filter for leaks etc

Yeah rabs that's the method i'm using... I think there might be a code stored actually that could be on the money.... ta....

as the title says...... it gets to the "awaiting confirmation" screen however holding the Set button doesn't do anything... or any other combination of buttons.... (75k service, VZ SV6)

mine says 12 kilometres DTE and 3 Litres remainging in the diagnostic mode but only takes 54 litres to fill up (there's still 21 litres in the tank in other words)

Tyre pressures.

Is there no T/C button on the centre console?

sounds like coils definitely....

Remove the torque abuse control (so higher power will be available at slower speeds/rpm) ... this will feel like the car has more lower end power as previously it was limited so people didn't do burnouts etc Hopefully improve fuel economy and increase ouput.

No they CAN tune the engine, just can't change the gearbox (Shift patterns etc) like you can in the 4spds.

VCM can certainly tune auto VZ V6's.... NO a dyno tune will not fix ANY issues or faults on an engine. (it is all about editing the stock fuel air ratios, ignition timing at different throttle openings etc) If anything it will make the engine work harder and stress more therefore making any...

the extras being?

If the front wheels were fairly out before the alignment, them now being straight(er) will cause less 'drag' and thus make the steering feel a bit lighter... if thats what you mean...

8.9 seconds is the factory spec (V6 auto)..... obviously depends on many factors, the ageing/condition of the vehicle, ambient air temperature (faster on cold nights than in summer)... weight on board, the road surface etc, fuel used...

Rebuild the only option?

Only on thursdays??

Yeah full comprehensive... it was the other driver at fault anyway. I hope they can do a good enough job to get it back to how it was (ie. immaculate) ....

ARRGHHH FML after 7 days someone crashes into me from behind, pushing me into the car in front! She's now on a tow truck. :(

Even for those specified 5W-30 (ie even on older Falcon's motors oil cap it says only use 5-30) and Alloytecs etc?

exhaust, VCM tune, maybe some rims. just trying to find some i actually like the look of on an sv6....
