Headlight Failure Service Requird

Raddish · Oct 31st, 2017, 19:02

Hi,
I've hot a 2010 xc70 d5 auto.
On start up I get a warning 'Headlight Failure Service Required' for a few seconds, and a orange bulb symbol. I've noticed this also doesn't move the headlights on start up. Times I don't get this message they move on start up. I've noticed that with or without the message , both lights work, and they turn with the steering wheel on driving the vehicle
Today I went to a vehicle battery place near me. They confirmed the battery is a Volvo battery 800a 90ah. It's has when tested 12.41v, and 802ah, and when started car pulled 92ah, also car alternater was giving 14.53v.
I've ready the fault is often the battery, but not too sure mine is, I think battery is original, should I just replace? If so with a 90or110ah? Or is the fault somewhere else?

The battery on my XC70 was 10 years old when I replaced it earlier in the year so yours may not be quite ready to skip just yet. Rather then spending upwards of £100 on changing a battery which may be perfectly serviceable, get the fault codes read with VIDA to see what's causing the error code.

Hi,

I would disconnect both headlamp units and reconnect them and try again.
Could just be a dodgy connection.

Had codes ready today 5 errors for right headlight level mechanism etc. All now cleared and later on same dashboard error came up.

How should I disconnect lights?

Hi,

If they are anything like mine (S80 MY08) then you should have 2 "tent peg" like steels to hold the unit in position.
Remove those and slide forward, plug is on the back and takes a little work to wiggle off.

You'll only need to remove the right one as that is the one with the error.

The symptom your getting is usually due to voltage drop when starting. I had that warning on and off for a couple of years usually when the temp dropped in late autumn. Car started ok and everything else worked fine. Battery was the original and after standing in cold overnight the voltage would read 12volt or a fraction under at battery with a meter. New battery cured the warning. If you do fit a new battery make sure it's fitted in accordance with Volvo instruction. Switch off and allow to stand for ten minutes before disconnecting battery .I caught my local tyre battery shop just as the fitter , I use that term loosely ,was about to disconnect the battery with the engine running !

I had this error message when my car was brand new. I normally park my car in the garage. When I visited Scotland at Easter it was parked outside and the error message came up. I went to the dealer and they applied a software update which cured the problem. This was in 2009. I'd be amazed if by 2017 your car hadn't had this update applied but it might be worth asking.

My 2008 D5 was doing that occasionally when starting the engine.

It still had its original Volvo battery. New battery solved the problem earlier this summer.

Voltage on the original battery with engine off was 12.3V however it dropped considerably when cranking the engine and took a second to get back up again. The new battery voltage (Bosch S5) doesn't drop as much - as reported via ODB/diagnostics logging I was doing before and after battery change.

Old tired batteries don't just have lower 'resting' voltage, they struggle to deliver 'power' when needed - the latter is harder to detect.

Thanks chaps, I'll remove it this weekend, if it still occurs I'll then change battery. Which one 90 or 110 ah?

Just a thought but - could you not prove/disprove the low battery capacity theory by using a set of jump leads and a second/friend's/neighbour's vehicle, before you go to the expense of a new battery?

With the donors' alternator running and good battery tied into your power system that should be more than enough total instantaneous capacity, given that your's already has enough starting current available.

For whats it's worth, I ran my XC70 2008 D5 with an obviously degraded/failing battery for a couple of months and whilst I had poor starting performance and several 'low battery' warning messages, I didn't encounter any headlight issues.
