Non starter after battery change power saver mode

Post by rupesmcd »

Hi all,
I have a non-starter. 2.2 HDi.
The car started sounding like the battery was missing a beat about a week ago- hesitant to engage stater motor, particularly when cold. Yesterday at my Mums it sounded like it was on its last legs, I was amazed it started to be honest. Unfortunately when i got home (from Mums- some 15 miles) I turned the car off outside our house in order to unlock the back door (of the house)- when I got back in to move the car to where i park it it wouldn't turn over, the starter motor limped a bit, then nothing. Dash lights were still on, interior lights and heaters, windows etc were still working. Anyway, I was now blocking the road, and a bloke turned up in a tiny fiat wanting to get through.
Bother.
He kindly offered to jump it- we connected it up, no joy- in fact things were now worse- 'entering power saving mode' had appeared. I ignored this warning- presuming it was actually trying to conserve power in order to start (more fool me).
He and I tried to push the car to where I park it (literally 150 yards away) but it's a big bird, and it got stuck on the corner where there is a slight up hill. He abandoned me at this point muttering about his wife and it going dark, and all sorts of helpful things. I ran to our friendly local mechanic round the corner and he gave me a jump pack- 'this'll get it going', he said. So, black to black, red to red, away we (don't) go. :cry: car still beached in the lane at this point, 'entering power saving mode' not good.
Mechanic then came with his Vitara and he and I had a merry few minutes dragging my nice car around trying to get it out of the way and parked, unfortunately it did roll into a wall when i was in control of the brake (it was dark, wet, slippery, car had no lights, I must have pressed the accelerator and not the brake etc etc). There is now a ding on the rear bumper :frown:
Anyway i got it a new battery today and removed the old one. I am quite ashamed to say i didn't check any procedures before and just removed the old one and replaced it with the new one. We are now in power saver mode- no interior lights working, windows won't work, car won't start, 'entering power saver mode' displayed on the dash on ignition.
I tried a soft BSI reset after reading some threads- but I can't open the windows, so I don't think it has worked. Have i screwed it up? I am about to go and disconnect the battery- and will probably leave it disconnected until the morning. I have just the one key- and the fob doesn't work.
The car is a 2003 2.2HDi- defapped and remapped with Doggies magic file.
Surely I can still reset the system somehow? Will disconnecting the battery over night help? I could do with getting the windows to open to do the BSI reset procedure properly.
Any advice appreciated! I need the car this weekend really! It was a bit of a squeeze in the wife's 205 today (we have 3 kids....) :(

If the lights aren't dimming out when you're turning the key then I'd think it's more likely to be the starter that's the problem. Jump starting these cars is a no.no, you can do all sorts of damage (it's in the knowledge base). Hopefully disconnecting the battery will help, you might need to give it a charge now too.

Hi mate, my old 406 did this twice.

Have a look at the back of the starter motor, its probably covered in oily gunk that get blown over it by a leaky air doser. It may be a new starter is on the cards, but its fairly easy to replace ( 45 mins ) and all should be well.

Will the car start with a bump start? Once the car has started the 'power saving mode' will disappear too.

If you have to do a jump start, connect red to red on both cars batteries, and blacks to the slam panels or similar, not on the battery.

You want a welding supressor across the leads, I wouldn't risk it otherwise. It might do nothing but...

Thanks guys. Starter motor- i bet that is what's up- it already had a new one a couple of years ago- but i guess if there is gunky oil getting on it it could have gone again- and there are definitely gunky deposits in that area- I'll check more thoroughly tomorrow. It also rings true with the fact that it wasn't really sluggish battery performance- but more of a struggle for the starter motor to engage/turn. At least I have a nice new battery now and (presumably) a perfectly good one in the boot too! :frown:
I'll start the ball rolling tomorrow with getting it replaced.

I replaced my starter the first time round with a second hand one from another member, it lasted all of 6 months before slowing down, struggling to start and then giving up on me when I was parked outside Tesco on double yellows.... :roll:
