Hello there,

I recently bought a Volkswagen T4 and want to install a new radio. Unfortunately, someone had already installed a non-VW radio, which did not work when I purchased the car. I dismantled the radio and found this cable harness.

I have already identified the speaker cables, and now I am trying to identify the remaining wires. I also believe that the cables connected to the terminal block (Lüsterklemme) are from the old radio installation.

I would be very happy if someone could help me out with this.

Thanks a lot.

Greetings from West Germany

My "new" caravelle t4... 2003

Title: Finally pulled the trigger on a VW T5 L2H1 — first van build. Any advice before I overengineer this thing?

After months of lurking, I finally bought a 2009 VW T5 L2H1 with ~200k miles on it 😅

Found a surprisingly good deal… only catch was it was ~800km away from home.

Our very first “vanlife weekend” was actually done in a standard car, trying to get to the seller... so this already feels like a massive upgrade.

The build

The van definitely needs some love, but I have access to a really solid workshop with tons of tools and people who actually know what they’re doing mechanically, which feels like a huge advantage for a first build.

So far:

• Added 2 side windows + a roof window
• Started treating rust on the chassis
• Trying to revive the factory Webasto heater
• Planning to make it road legal as VASP in France

The plan is basically to build something simple and reliable enough for road trips and remote work, while still being comfortable enough for longer trips across Europe.

First destinations on the list:

• Italy this summer (very hot so)
• Pyrénées soon after
• and hopefully northern Europe next winter for aurora hunting (very cold, sooo given I can get the webasto running !)

Biggest thing I’m struggling with right now is the water system / hot water setup. I plan to take the coolant loop from webasto/engine to the back compartment for other uses (heat exchanger to air for heating)

Now I’m wondering if I’m massively overengineering this for a first build.

Would love to hear:

• what you regret doing on your build
• what you wish you planned earlier
• smartest “small” upgrade you made
• and especially how you approached water systems in smaller vans

Will definitely post build progress if people are interested.

Looking at a 2010 T5.1 later today, asking price is £10,600, Obviously for a car that’s 16 years old there is going to be rust and what not, the car to look at looks in tip top condition with only minor bubbling at the bottom of the door frame (in the video he pushed on this and there was no crumbling ect) i’m just a bit worried about the rear suspension corrosion, is this likely to need sorting asap? If so is this something i should stay away from or knock him down on price to factor in the cost of repairing that?
would appreciate your knowledge on this one!
Thanks so much

edit to add, what are we thinking about the oil leak? i know it can be something small but what should i be looking out for when viewing ?

Hey everyone.
need help finding out what could eventually be wrong with my circuit board on my 1997s VW T4 for the air fan in the passanger room. Some air amways comes out of the outlet but its like 5% of what it should be capable if, also i cannot change it with the steplews control dial. heating does not start anymore. I mean it does turn on SOMETHING, it does a summing noise but airfan is does not move. I do not have AC.

Someone have a diagram for the control circuit?
Or any idea? pls help

Hello, looking at buying a 2.5tdi t4 camper and asked for a video of the rust spots and got this video, anyone more experienced than me able to have a look and give their opinion

Much appreciated
