Mimmo
Hello everyone, my name is Mimmo. I live in Turin, Italy, and I’m writing using an online translator, so I apologize for any mistakes in my English.
I’m very happy to be a new member of this group.
Two months ago I bought a 2012 Volkswagen California T5.2 with the 180 HP BiTDI CFCA engine, 6-speed manual gearbox, and front-wheel drive. Since then, I’ve already built a sliding rear storage drawer in the luggage compartment and installed an external shower connection with both hot and cold water mixer control.
For the hot water system, I installed a small 9-liter boiler with a 200 W / 12 V heating element. I placed it in the lower compartment of the kitchen cabinet under the sink. Everything is working perfectly so far.
Unfortunately, I do not have the owner’s manual in Italian, so I’m trying to understand the most important information from the German version.
I would like to ask a few questions:

Unfortunately, I do not have the owner’s manual in Italian, so I’m trying to understand the most important information from the German version.
I would like to ask a few questions:
- Is it possible to find an Italian owner’s manual for this vehicle, preferably as a digital file rather than a printed copy?
- When connected to external 230 V shore power, does the onboard charger also charge the starter battery, or only the leisure batteries?
- Where is the onboard battery charger located?
- The 230 V / 150 W socket on the left wall behind the passenger seat:
- Is it powered by a 12 V DC to 230 V AC inverter?
- Is it a pure sine wave inverter, and is it safe for charging laptops and other electronic devices?
- Where is the inverter located?
- I measured the voltage at this outlet with a voltmeter and it showed about 198 V instead of 230 V. Does anyone know why?
- Could someone provide the electrical wiring diagrams, especially the fuse locations and the body channels/routing used for the electrical and electronic wiring harnesses?
- Does the original charging system work reliably and efficiently?
- What is the typical battery autonomy for running the refrigerator before recharging is needed?
- The van currently has two newly installed 80 Ah AGM batteries. I would like to replace them with a single 150 Ah lithium battery (NDS Tempra).
I understand that I would need to install a DC-DC charger between the alternator and the lithium battery, while keeping the original charger because the lithium battery I chose has a BMS that can also accept lead-acid charging profiles.
Has anyone already done this conversion? I would really appreciate any advice or recommendations.
