Hi Gentleman, I will away for 2 weeks time, can I just disconnect the battery and reconnect again after return. The only thing I know is to input password
to turn on the monitor/radio...is that's all ? Thank you in advance. eric

 

2 Weeks shouldn't be a problem for a healthy battery, I have left mine a few times at the airport without disconnecting or doing anything special. Does the central locking work if you disconnect it?

 

Hello Alecescolme : Actually I did it once for release the locking hand brake but did't check
if the central lock working or not. Battery was changed 3 weeks ago so should not be any problem.

 

If you disconnect the battery, you will also need recalibrating the parking brake and the electrical windows.
Unless your air suspension shocks have been replaced recently or are very healthy, I think it is also better to leave the battery connected to allow the ASM to level the car every day (at least during the first week, not sure if this also takes place beyond one week) in case there is a small leak. Otherwise there is a risk to retrieve the car down, which may damage the bladders.

 

The first air strut(second hand from first seller) that I bought from USA was bad,it has leakage.After a lot of mails discussion and seller willing to refund.However,paid USD350 already for labour.

Now the car is still sit down and going to buy another one from another seller who sold me a good one. Hopefully stop the nightmare for a while.

This LOVE the car but also hate it !

 

I would just leave it as is, maybe switch off park brake.

I left mine for 4 weeks with no problems.

 

I should have had followed your instruction to let the car without EPB on !!!

I have asked my sister to at least start the car and run it for several minutes during my vacation. She told me the car can't start after a week.

When I back,2 weeks,the car battery has no power at all (New battery changed a month ago). I bought a power bank for jump start and it did. However, NO APPLICATION ON BRAKE has lighted and can't move then car.

I did several times disconnect the battery and start ignition but all failed since the original battery has not enough power.I feel if it started by jump start then the BRAKE locked.So,I jump started again and leave the car run for a 10 mins.
Disconnected the battery and leave it for 2 hours. When I back to the car again,strange,the car has raised up to normal (One of the air suspension need to replace and waiting for part therefore the car always down) Hard to understand.

Anyway,I just start the car right the way without jump start and this time work !( the battery been charged during my 10 mins run,I guess.
After several time pressing the brake pedal (follow the monitor) and hand brake then everything goes NORMAL..thank GOD !

I take the car to run about 10Km,the air suspension shows normal..really strange.

I hope it keep the same heigh after the night.

Wish my message helps to some member .
Regards,
eric

 

10 mins of idling is peanuts wrt to recharging the battery.
You need charging it a full night, otherwise you will encounter the same problem of no start tomorrow.
Even more, you should check that your battery is not on its way out, not sustaining the load. Or you may have a drain...

Wrt to your suspensions, 10 mins of idle may be enough to sufficiently warm the engine bay and the shocks so that they don't leak anymore under cold.
But on a cold morning you may find the car again on its knees...

 

Yes you are right as the EPB has not function therefore the ONLY way to me is let it run for 10 mins.However,it has enough battery power to start the engine without EPB malfunction.

I just ride for 20 mins,after 15 mins normal and on the last 5 mins. The display shows "air suspension fault and car too low again" which is the same as before. I hope to find a piece air suspension,left side soon.
On the mean time, have ordered the repair bump kit from UK.

eric
