Warning Lights - DSC Sensor/Alternator

flimper said:So after a few hours googling, I've narrowed down the problem to a DSC sensor, an ABS sensor, a battery, or an alternator (or voltage regulator)
I told you at the beginning, glad that you finally listened me. so many ppl went through this some actually managed to spend so much money fixing something that is not related to actual problem.

Must admit I thought the Ctek was cleverer than that.flimper said:
Notwithstanding the (somewhat brusque) advice of others, I think even a fairly basic code reader would be able to tell you if it's an ABS sensor. My Autophix 5900 told me exactly which wheel had the issue.
Got to be worth a check of that, it's even easier than swapping a battery.
Well a quick google of those still initially points to either the yaw sensor or a wheel sensor. But I would have thought a wheel sensor would have given a code specific to that corner?
Only other thing I can find for the system voltage too high is a faulty regulator on the alternator, but it also seems to say that this code is often tucked away and no-one notices, so possibly it's not connected.
Did you try resetting and seeing what came back?

It’s a weird one, Martin, because the lights aren’t “on”, they just flick on occasionally. Normally the trifecta stays on and it won’t go away. This suggests to me a connection issue or an early warning notice for a failing component. All dry under the seat where Flimper previously had the yaw sensor replaced. Wouldn’t the regulator throw a battery light?
Well if they flick on and off, have you tried wiggling connectors on the sensors etc to see if it'll come back.Zedebee said:

I think you could be right about the battery light. What I was reading was suggesting that the code for that could have been generated way in the past but never been seen before. Obviously not in this case though.
This also seems to rule out a duff battery though doesn't it?
Yes, and Flimper’s battery is new, he keeps it on a ctek and doesn’t have any other issues. No issues with starting the car. Very unlikely to be the battery IMO.enuff_zed said:Well if they flick on and off, have you tried wiggling connectors on the sensors etc to see if it'll come back.Zedebee said:

I would be trying to identify when the lights are coming on and see if I could work out a pattern (e.g. in a hard turn, or going over bumps, or when DSC or ABS kicks in).
Had the problem again this evening but this time with an additional twist. The heating lights on the centre console joined the party by going on and off in tandem with the warning lights. The green lights stayed on, but the orange ones played up. An electrical issue a definite possibility still.
Today's update: Went to Halfords to get battery checked, guy said voltage/amps all fine. Then putting it back together he noticed a leak, which turned out to be battery acid. Battery replaced FOC, drove less than 10 minutes and lights re-appeared. So it's not the battery, but could it be something related to the leak, seems too much of a coincidence to me :?
