Hi everybody!

I have a 2003 Stilo JTD with the Webasto heating system. The problem is that normally I make really short trips (10-15 min) and the heater normally needs to work around 20 min to get to the proper temperature, so my battery is slowly dying and one in a while I try to make a longer try in order to charge it.

Now, my car also have a DEFA electrical block heater system that works with the normal 230V plug and I would like to install a battery charger that is connected to the heater system and the battery, so both processes can work simultaneously.

Here's a picture of the device:



And here's the website in case you want to check it out:

So, my question is, as this models are really complicated about their electrical systems: Will it cause any electrical problems like crazy warning lights or ECU problems, etc?

Thanks! Greeting from Northern Finland

I don't think you should have any problems with DEFA. I've got an in-line engine (coolant) heater and alarm from them, working 100% with the CAN system.
