Fitted a new head unit yesterday, and the car would start...
Hello guys.
Fitted a Sony head unit into tank yesterday (citroen c5 2.0 hdi estate) , and this morning tank wouldnt start.
Had to jump start it with leads.
Related or not?
It has been having trouble starting before but always would after about 5-7 seconds.
So I expect the battery is a little old anyway.
But the head unit is wired in permanent live, but last night I held down the off so it turned off completely.
Would the two be related, or do I just need a new battery or is it worse?!
Thanks in advance.

Hello if the car been struggling to start before all this you need a new battery for sure.
The radio will just add more strain to the battery problem.
When knowing a battery on the way out best to change it. They wont last for ever like any battery.

Is there a procedure to changing the battery , or is it pop in or pop out?

When changing the battery if the radio has codes make sure you have them ready.jlktiling wrote:Is there a procedure to changing the battery , or is it pop in or pop out?
Also make sure you take the keys out of the car. Because sometimes the doors will lock when you put the new battery back on.
But you should be fine changing the battery over.

Yup, know what you mean, when Citroen did mine over here they didn't follow any process, haven't had anything go wrong with it from them not doing so, but your mileage may vary.jlktiling wrote:Ben82 wrote:Take a look here for the safest process.jlktiling wrote:Is there a procedure to changing the battery , or is it pop in or pop out?

Re: Fitted a new head unit yesterday, and the car would star
As a note: I've seen some techs just disconnect the battery without the usual safe BSi procedure, and I'll admit I've done it myself a few times like that (and the proper way too)
Without any disrespect to the PSA group, I do think its a cause for concern that you can potentially corrupt the unit by not doing the procedure, imo that should not be possible.

Re: Fitted a new head unit yesterday, and the car would star
The battery procedure is a bit like shutting down a Windows PC. By letting it complete its shut down procedure, it clears down any temporary variables. However, if you just kill the power, these don't get cleaned up, and might get in the way at a later date. Worse, if it was running a critical routine at that point, it might fail to start up cleanly next time, or maybe not start at all.
Yes, the battery routine takes time, but it is always better to be safe than sorry. 9 times out of 10 you won't have a problem (probably better than that), but the 10th time it goes wrong, usually when you REALLY need the car!

I'll second that. Wouldn't start, l flattened the battery, did a quick swap and the immobiliser locked out the ignition, had to take the bus and do it right that evening.

All this faffing around really puts me off ever owning a C5 or C anything for that matter...

Re: Fitted a new head unit yesterday, and the car would star
Might I also suggest double checking that the radio is off and not drawing any current as it seems a bit of a co-incidence that changing the radio and now you have a flat battery

No problems this morning. But the memory on the radio hasn't worked. So I guess I'll need to swop the permanent live & switch cable around.
