Battery light came on

[Number86]

I'd just set off on my way from work, had the increasingly more often coolant 3 beeps come on, and ignored. Then, on joining the A40 and give it medium acceleration straight after the battery light started to flash on for about 10 seconds and then stopped.

I gave it a few more beans about 1 minute later, and the batter light came back on, and upon accelerating I felt the car judder a bit and the lights dim.

I crapped my pants and drove like a granny all the way home, with no trouble.

Near home I booted it again a few times to see if I could recreate it, but nothing.


Any ideas??

Oh, the OBD reader threw up 17695 as an error code when I checked after the journey (no idea if it was there before)

HALP!



EDIT: That code appears to be {Turbocharger bypass valve open}

Ive had it a few times put my toe down and the battery light comes on but car still runs fine, I checked the charge rate and was all good so didnt do anything.still on first battery and not done it in a long time again, See how you get on

Battery or alt knackered mate. You need to check the volts with the engine off, then with it running, you should see 12v DC when its off, and around 14.7v DC when running.

sounds like an alternator problem mate

scotty1 sounds more on the ball. Go kwik fit and they will do a free check for you.

Tell you if its battery or alternator.

 

[RikH]

its alternator
mine has done this twice, within about a week, both under hard acceleration.
comes on for 5 seconds then disappears--its never done it since though........

check belts,
check voltage with car off and when cars running
mine was fine and has never done it since, 6 months now

Hmm.

I, well my bro when he was over (he's the smart one ) checked the battery and alternator just a couple of weeks ago and all was fine, as I am having issues with dimming lights when the music is turned up slightly.

I'd be guessing it could be a belt problem, if it's under acceleration??

Is the turbo bypass valve the DV?

Thanks again.

Mines been over a year now and still all's fine, I thought it was bad wiring or bad earth

Please note the cold temp can cause your battery to die, or to loose power.

check your belts, charge rate, battery and alternator.

Battery could cost up to £130 if you fit yourslf
Alternator cost cost from anything to in excess of £350 quid unless you do it yourself.

In all honesty....... get it checked soon as you dont want stuck on the hard shoulder in the rain and cold.

 

[Number86]

130 for a battery?

WTF!

 

[stuart86]

what part of the a40?

 

[Number86]

I travel between perviale and loudwater A40-M40

I've seen a black leon FR and a red/blue basic spec ones but I don't think I've seen yours!

 

[Number86]

This happened again this morning.

The only link to last time is that it's been damp and cold. Times in between it's only been cold.

Could that be faulty wiring or a belt? Could any odd job mechanic look at this for me?

Mine is a black FR replica lol. (except for my wheels )

It's on a private plate.

 

[stuart86]
