That sounds about right. It's a shame they couldn't make it work for
these cases though. The system seems to have all the hardware it needs
to give you the grip of two tyres instead of one, but it turns out you
have to shut it down just when you'd expect it to be be really handy.
Yep. It backed off the throttle to the point that I had to declutch to
avoid stalling. If I were writing the software, I think I'd stick in a
clause something like "If the back wheels are going at less than 1mph,
then leave the throttle alone"
I think Quaife do an ATB for the 9-3. I'd be seriously tempted to get
one if my gearbox ever went bang. I wonder how it would interract with
the traction control...
It's handy for those over-enthusiastic exits off roundabouts, but I
find it pretty useless for standing starts. It's certainly no launch
control, which is annoying because I'd say the cars biggest vice is
Traction control doesn't work on proper slippery surfaces, indeedy, I can't
think of any car with traction or stability protection that doesn't skit
around on ice. The issue with your above ides is that it'll cause excessive
wheelspin... (see below).
Our old office car park in York had a small gradient, but it was enough to
make it impossible for the company 3-series models to get up or down it.
'Twas brilliant. :)
It shouldn't do anything - but it's arguably over the top most of the time.
Yup; now imagine it won't back off the throttle when the rear wheels are
barely moving. :)
That's the front wheel drive aspect... I don't launch the 1.8t much, but
when I have, getting it rolling and then nailing it is kinder to the tyres
and drivetrain and doesn't seem sluggish...
You'd get no more wheelspin than with the system turned off as you
have to do currently - i.e as much wheelspin as you want - but with
some braking to the fastest spinner. From my mud-plugging experience,
I can report that there seems to be no such thing as excessive
wheelspin in that situation anyway.
I'm a fan of RWD, but it does have it's down-side...
Probably right, but I'd love to try driving one.
I'm talking about a cut-off point much slower than walking pace. On
normal roads, the back wheels would only ever be going that slowly for
a few milliseconds after pulling away.
On the Aero, it's really quite tricky to just get away smartly.
There's a fine line between bogging down and lighting up the tyres.
The traction control allows too much wheelspin to make real progress,
so you have to nurse the throttle all the way through first gear until
you can get some power from second. Only then you can nail it - as
long as it's crispy dry...
Gotcha. I'll try it. I remember asking what the problem was with the
3-series we ran, because apparently, their electronic aids made them
"impossible to drive on snow." This of course is complete gibberish; it
made it impossible to drive at ordinary speeds on snow and ice and maintain
Me too. The issue here was more that the electronics detected wheelspin on
both sides and cut the power, as you've described. Issues were more
complicated because the car park wasn't especially large and it was often
Me too - but I'd have to upgrade the 1.8t to notice anything first, run that
for a few months, then try it.
Right. I'm supposing that there's a reason why this hasn't been done,
because as you write, it seems logical enough. Perhaps it's there as a
Yes. I tried a few.
I'm trying to feel sympathetic, but I'm failing, as you have lots and lots
Have you tried launching in second?
The other trick is to get it rolling in first, gently select second (as on
don't bang it in gear, bang the clutch out and let rip) and the
progressively go? That used to work moderately well in the 9-5 Aero I used
to ride around in - as you say, assuming it was bone dry on a god surface.
I've given it a go, but it feels so hard on the car. There's over 80K
miles on the clutch as it is...
It's worth a try...
Actually, there could even be something wrong with the car. I'm sure I
read somewhere that torque was supposed to be limited in first and
second, but I don't get any indication of that on the "turbo" gauge in
second - it happily goes slightly into the red, just as it does in all
the other gears. It's harder to tell in first because of the
wheelspin, but it doesn't feel limited there either.
Ah! Fiddle brakes. Banned from trials cars years back as it made them too
good. Apparently a lot of the 4x4 trials crowd use 'em now. Nothing new
under the Sun, and all that..
As I recall the trick with using the handbrake to control wheelspin
#under those conditions was to not be afraid of using the throttle.
Got a Citroen GSA though a very deep mud-hole on handbrake control
of wheelspin a couple of times, though on one occasions the tachometer
was up against the stop for a bit (not that it mattered much, with
that engine...). Was a bit more cautious with the 90s in snow, as
they were institute cars, but again a bit of throttle and a good
tug on the handbrake (but /not/ held on the ratchet) kept the
show on the road.
it more acceptable to believe (or, at least, say) that than to accept
that SAAB were responsible for a very ordinary, rather dull and
frankly not-that-good car (OK, the 9000 is fine on a motorway
or a straight road - ride aside - but it's pretty grim on a
Well, you've got a very strong case there :)

They switched to back arround the time (one year either way) of the face
lift, and used 9000 style brakes front and rear. With some tweaking you
can give a facelift C900 a brake upgrade using 9000 aero parts.

It definitely sounds like something is wrong then. I don't know how
the interlock is done on 2007 cars, but your dealer should certainly
be able to sort it out if they can repeat the fault. Have you tried
fiddling with it to make it happen again?
No, it won't wear it out as long as you only pull it on with the car
at a standstill. Using it whilst moving will certainly cause some
wear, so go easy on the handbrake turns...
