I store mine for 4 months, it is a TDI and I just fill up the fuel tire pressure at3 psi more than the door post pressure, note I run at that pressure anyway. Ensure everything electric or electronic is turned off. It is stored for the winter, inside a cold storage with temperatures going down to -25 and so far I have not had any problems. This is my second year doing this and will pickup my Touareg 2 April from my cold storage. Hope this helps I didn't have flat spots on my 20 inch tires last year. Did my 30,000 km servicing just before storage. Ad blue, oil, and windshield washer fluid -40 degrees.its just a storage unit (no climate control)
what is the best way to keep the car for 5 months?
I read I should leave fuel full
what about battery? since its not too accessible.. ? windows..? what else should I concern?
I AM CONSIDERING DOING THAT AND BE WORRIE FREE AT LEAST FOR THE BATTERY!Of course you can get to the battery by yourself.
It's not that hard: you just need the right tool [which is easily acquired] to undo the two floor bolts to hinge the seat back but I see you have a T3!
Here's the how-to - it's a very easy ten minute job on T1s and T2s.
There are different opinions on the T3 as to whether or not the seat still hinges [electric seats may be different] so you can check this out on yours:
