Traction control light flashing... a *lot*
Discussion
Hello.
I took my V8V for a spin yesterday and noticed that the traction control / stability control light was flashing rather frequently. Almost every bend in fact, even when driving sedately.
It definitely never used to do this. It would only flash when giving it beans.
The suspension feels fine, the front tyres are quite old and will need changing soon, but I can't think why this would affect it?
Any ideas gratefully received.
Thanks!

It is a weird system on the Aston
Talking to BR it seems it does actually intervene BEFORE the light comes on
When it does this it starts to cut power and applies one or both rear brakes
Both my roadsters have done a set of rear pads in 13k miles because of it
Worn front tyres won't help as it will promote understeer
Poor geometry could also make a difference
I found switching to the PSS from the OEM RE050 tyre also made a difference
On our recent Euro trip I also switched the DSC to track mode which helped but can only be done on the later cars

^Interesting. The front tyres are worn unevenly across the tread (more wear on the inside) which makes me think of a tracking problem, but my dealer said this was normal for a V8V.
Maybe I'll get the geometry done when I get some new tyres on the front.
I guess my biggest concern is a leaking suspension strut, but the suspension feels fine. It might need to get worse before it becomes obvious to me, though.
/edit: Don't know if I can put mine in track mode. It's a 2010 V8V. I'll have to look in the manual.

Inside edge wear is normal IF you do a lot of Mway and straight A roads drives.
I've never see it on my RWD cars
I always see even front tyre wear and a slight bias to the inside edge on the rearsBut then I regularly do the geo and like to "make progress"

Also, another thought: the rear tyres are new. Could the difference in rolling radius be affecting the traction control?
It would have to be a fair way out and often screws with the ABS system when it is an issueI use this site for offset and diameter checks

Yes, I checked the pressures before taking the car out. They were spot in.
It's a good point, though, since when I had the rear tyres replaced the tyre shop put too much pressure in and the car handled horribly. I was amazed the difference incorrect tyre pressures made to the handing.
/edit: 2.3 and 2.5 bar front / rear from memory.

The Vantage is the first car I have ever owned that uses up the rear brake pads more than twice as fast as the fronts. You can witness this by how dirty the rear wheels get while the front wheels are still clean. That AM traction control must be pretty aggressive.
Your rear wheels will be a lot clean on your new one if you put it in "track" mode

An ineffective damper could cause the DSC intervention problem.Maybe I'll get the geometry done when I get some new tyres on the front.

Usually a sign that the car is being pushed into understeer regularly....Simon T said:
How does that work?
Adding more steering as you apply power, generally equals understeer [occasionally oversteer depending on conditions, gear etc]. The cars DSC system will apply the inside rear brake to counteract the understeer. So, when we see a car that is wearing out rear brakes before fronts, it tells us about the way the car has been driven. You must unwind steering as you apply power, which means turning into corners later, to open out the exit.Gassing Station | Aston Martin | Top of Page | What's New | My Stuff
