Jump Start / Battery Chargers

Hi all,

Had a Stelvio for about 4 months now which we bought second hand and I love it! Also love the fact I've not seen another one on the road in London yet.

I washed the car yesterday and then this morning went to the car and tried to start it and nothing. The only thing I can see on are the exterior door handle lights are on. Pressing the start button doesn't register anything - not even the dash lights come on.

I tried to jump start it from an older Audi TT. First time I've done a jump start without the farther-in-law helping me. I hooked it all up correctly but still nothing in the Stelvio. (I didn't leave it long - less that a minute - from connecting the leads to trying to start the Stelvio so I'm not sure if that was a mistake?)

Alfa Road side assistance came out but their van was too tall to get into the height restricted car park - lesson 1 always mention restrictions if phoning Alfa care! The guy did test the battery with a meter and he got 4.5v instead of the 12v so said the battery is very flat.

I'm not waiting on a second smaller recovery vehicle to come and jump start it. Fingers crossed this works.

So I've a number of questions from this...
1) How did the battery go that flat? I used the radio whilst cleaning the car but could that have really done it? The other thing I parked much closer to my house any issues with keys being nearer the car that could flatten the battery?

2) If they can't get this recovery truck in how can I disengage the parking brake (and gears?) to push the car to some where accessible?

3) I'm considering a jump starter - if so what size do I need? The recovery guy said the jump leads I had would have melted before starting the car - they are old but is that really true they've jumped a 3L Audio TT before? Is the Stelvio that power hungry? (The recovery guy said just get a spare battery for a 1/3 of the cost of a jump starter)

4) Any recommendations on a battery charger? Again is there a certain size that is needed?

I had the same issue. It’s possibly a software “campaign” to fix a BCM fault which may cause the turn signal to turn on while the engine is off, this can result in total battery discharge. At least that’s what my dealer flashed onto the car and it’s been fine since, typically goes into float on my tender when I attach it weekly within an hour at low amperage.

For a battery tender my dealer’s Alfa/Maserati tech said something with a max of at least 5A for charging a deep cycled battery, 1A is sufficient for floating otherwise. I’m using the Battery Minder 128CEC1 because it’s really flexible on battery types.

Edit: there’s an eyelet on the transmission under the car. Thread a bolt into it to put it into neutral. I don’t recall the dimensions, your dealer or AlfaCare should be able to provide it. I think it’s M6x32

I have one of these, they're great (LiPo battery). Very compact, retain charge for a long time, great to start car if you get stuck with an empty car battery :

Re battery chargers, Alfa sell a charger as accessory. This is actually a rebranded CTEK, well known make.I believe CTEK CT5 start/stop

Well I think things are about to become interesting...

The second recovery person arrived to jump start the car - and it wouldn't start at all. No noise, no flicker on the dial, nothing. Even with the recovery van and an extra battery pack connected.

Interestingly the radio comes on and is in Italian.

So now they are sending out a specialist recovery team that can get under a height restriction...this could be interesting.

Anyway an extra question - is there a way to open child locked rear doors when the battery is flat (or the electrics aren't working). We need to get our child seats out of the car before it goes into the dealer...

Normally I would say connect a battery pack to the jumpstart terminals under the hood, which should allow power to unlock rear door(s).
However, in your case, no idea if that would work as your battery seems really dead

We tried the central locking with the recovery van connected - nothing.

So the drama continues....

Last night Alfa Assist tried to get the car collected but clearly the tow truck company just wanted to swerve the job. We will be there in 40 mins. Phone back 50 mins later... we will be there in 40 mins.... when it got to 10pm I gave up.

So another truck has turned up this morning... with a jump pack actually got the dash to light up and the central locking to unlock. However it wouldn't turn over - you get a strange vibration on the brake pedal when it can't seem to turn over. Also the dash lit up like a Christmas tree.

I don't know if this success is because it was a bigger battery pack (although how can it be bigger than being hooked up to a recovery van?) or if it is water in the electrics it may have had some time to dry out...

Anyway it is still not going - looks like they are going to need 4 skates and a lot of man power to move it to a place the van can pick it up.

I assume there is no way to disengage the 4 wheel drive so that they only need two skates?

If you look in the owners manual there are instructions to release the parking brake and put the car in neutral but it can't be flat towed that way. Probably best to use dollys.

Another idea if you are just waiting anyway....

Hook up the Audi TT again making sure you connect positive to positive, etc., keep the TT running while it is connected to the Stelvio's battery. Let it stay connected and running for at least a half hour. This will allow the Audi's charging system to charge the Stelvio's battery some.

After at least a half hour try to start the Stelvio, again keep the Audi connected and running the whole time. If the Stelvio starts, go shut off the Audi immediatly.


Done this probably a hundred times to get various cars with completely dead battery's started. Most modern cars have a safety feature built in that won't even let the starter move if there isn't enough power, and The Stelvio takes ALOT of power.

Could be these people do not have strong enough jumper packs.

If theStelvio starts, don't shut it off, it will die again. Give it at least an hour at idle or a solid drive for 15-20 minutes, and really maybe get it looked at, battery tested etc.

there are 2 ways:
1 if you have (enough) electric power, you can switch the transmission to Neutral (and disengage park brake)
2 There is a mechanical way using a screw on the gearbox, from below the car.

Have a look here : unlocking auto transmission

^That only puts it in neutral, it does not disengage the driveshaft, so ok to push a few feet, but not to tow. Not sure if it is being flat towed or just pushed to a more accessible location.

Oh, only use your jumper cables if all the insulation is good and the connectors are rust free. The Stelvio takes alot of power, quite a bit more than a 1st gen TT if that is what you have. The comment about your cables melting may have been a scare tactic, but make sure they are in good condition.
