Car won't start?

[EssexVXR]

Vxr8 auto.....Just driven to the shops, come back out of shop and now car won't start? Turning key to start ignition saying ESP is off and contact dealer? Won't engage starter motor when key is turned all the way... Anyone had this prob? Should I disconnect battery

Sounds like battery is knackered?

What does the engineering mode state for battery life?

[EssexVXR]

Not sure how to get to engineering mode?

I'm getting a weird sound like a hover coming from engine bay when I try to start it up?

Press and hold down the left scroll wheel and turn on the ignition, after about 5 to 10 sec engineering mode come up.

Then just scroll though the menu.

Lucky I was outside a halfords when it didn't start, he checked the battery and was showing good at 12v? Ended up just disconnecting it for 10mins and seems to have cleared fault and starts now

Well it's done it again today after about 3-4 stops start all ok. Pulled up in a petrol garage filled up then car wouldn't start again. Showing same ESP stability control turn end of and please contact dealer, refuses to turn over

Your battery is fooked. What did eng mode report battery life to be?

[EssexVXR]

Doesn't show battery life? Just battery voltage in enigineering mode. Shows 11.9 on start up then creeps up to 14.4 within 10-15secs

Hmm - do you have a very early car? Those didn't have battery life in the menu.

If its less than 12V when it starts its obviously low. Rising to 14v just reflects that your alternator is working (hard) to try and charge it.

If your battery is more than 3yrs old it would be the primary suspect. Your error message is likely to be spurious due to low system voltage.

Yeah it's an old 07 reg I think. not had no trouble with it until I put it in to have the alloys stripped and powder coated earlier this week. Maybe they left the keys in and drained the battery. think I'll change the battery as you said can't hurt to try

I believe there is a BCM update for the older cars too which changes the way that the car allows the battery to discharge and charge back up again. Might be worth asking MF/WP or where ever you have the car serviced if they can check considering you have an 07 plate car.

But then, still change the battery. See FAQ's for the correct one, as it does matter. Bosch silver line from memory is one of the correct ones.

I contributed to the thread in that link and then thought my ECM was upgraded; but I don't think it was. My battery charging has done some strgae things like; 82% charge, drive for 46 miles in my hour commute on main roads and when I turn off and check the charge its still 82%. Do that for a week and eventually is jumps to 100%.
