Help required please.

The MiL had a brain op in March 2021 which meant they removed part of her skull which has yet to be replaced. This has meant her beloved RR Evoke has sat on her drive for over 2 years without being turned over.

She didn't want to sell it as it was her pride an joy. However, it's highly likely that she will never drive again. Which in some respects is a blessing as she was a terrible driver (50mph on a motorway type) however it will rob her of her mobility.

We're gradually getting her round to the fact that she will never drive again, and are looking at getting her car in a saleable position.
Hence the question.

The battery is flat as a pancake. Should we attempt a jump start or will it fry the ECU's and other expensive stuff to replace?

Is a new battery the common sense thing to do?

What else will (probably) need attention? The tyres are all full of air, however, the driveway is on a quite steep slope (approximately 30 degrees) so oil would have found its lowest possible point in the engine.

My initial thought would be to tow it off the drive, and start it on the road (which is relatively flat).

Any other ideas?

Check it's got oil in it, ideally stick the battery on charge, but jump leads would be fine.

Then press start and hope for the best. I wouldn't overthink it too much.

Sorry to hear that about your MiL.

For the Evoque - fresh fuel, maybe an oil change, charge up (or replace) the battery, pump up the tyres, and get it started.

Then call WBAC or Motorway or whoever, and let them take it off your hands.

Agree don’t try to jump start it. I would put it on a CTEK charger or similar, to see if you can bring it back to life.

A new battery could cost a couple hundred quid if you have to go to a dealer to get the battery coded to the car.

30 degrees - I’d start it on the flat. I’d just stick a new battery on it after two years. I’ve just started a Merc that was dry garaged for two-three years with a booster pack - the battery is scrap, can’t revive it at all.

You'll probably find that the parking brake pads have seized to the discs, so they will need persuading to free off. Are the key fob batteries ok?
Battery will probably be dead but there is no harm in plugging in a ctek.

That was my initial thoughts. I'll plug my one in it at the weekend and see it it make any difference.

When I replaced the battery on my Jag a couple of years ago, didn't have to get anything recoded.

If it does need coding, you can get ANCEL OBDII scanner things which are able to register a new battery. Version I bought is for BMW and cost £50 on ebay, but I suspect you could sell it on for pretty much the same price once the car goes.

Question about 'coding' a battery which imo is just a cynical way to screw more money out of us ...

If one were to attach wires to the new battery while disconnecting the old one/connecting the new one, ie no disconnection of the circuit, would it need to be coded in?

I mean, charging an old battery would change the amount of juice but wouldn't need any coding either so...

Just a thought.

Maybe the battery could be made to work again, but you could do the next owner a favour and just replace it. Otherwise, they won't know there is anything wrong with it until it spontaneously dies again at some point overnight or in their work's carpark in the coming winter.

Personally I don't think there's much to be done about the oil thing. You aren't going to get it to where it really needs to be just by rolling it onto flat land.

This. They won’t care or ask that it’s not started in 2 years. Maybe give it a wash first lol

My understanding is the smart battery monitoring adjusts the amount of charge sent to the battery. For a new battery, you want to reset that value and so it needs registering. Not sure what the consequences of not doing so are though?

Just jump battery and start it, fuel oil etc won't go bad in two years, it is a modern car. They sit sometimes for years in compounds .

If concerned about electrics get rac to jump it.

My understanding is that the BMS will eventually work that there is a new battery and compensate for itself without any need for recoding. I changed my wife's V70 battery without any issues.

I think the only option with WBAC is to get the car to them which means driving it or getting it trailered. You will get more for it with an MOT too obviously.

Motorway/Carwow buyers are trade and will collect the car with trade plates but it will need to be drivable obviously.

Coding a new battery is usual to stop the alternator over charging the new battery. Two years is nothing, yes battery most likely will be dead but rest of car will be fine.

My neighbour had the opposite experience with his BMW and decided that rather than knacker his new £200 battery, he'd get it coded. YMMV biggrin

Well, that's BMWs for you. Never get any trouble from the trusty old Volvo beer

TBH Id just stick some jump leads on for 5 minutes then jump it

Check the oil first & coolant , and engine bay in case rodents got in

If its on a slope , gently prise the brakes off , they will prbably be stuck on, but if you are lucky will release a decent drive will hopefully free them off

Battery is probably knakered, but might be OK

2 years isnt really anything , when I did similiar in past hardest thing was jet washing all the moss off

I'd happily use jump leads on it. Used correctly, they won't blow anything up, and once it starts, the car's alternator and regulator will take over. You never know your luck, the battery may take and hold a charge, and if you're selling the car on, why spend unnecessarily?

I reckon it will start relatively easily. I went to an MG ZS that had been sitting for 5 years outside, with a full set of tools, and ready for a scrap. Put some jump leads on and a gallon of super in the tank, it cranked for about 20 seconds and fired up like it had last been used the day before.

If it's petrol, you will definitely want to put some fresh fuel in the tank. Modern unleaded is generally junk after 6-9 months.
