Technical Fiat Panda 169 1.2 Bodycomputer kaplow.

[NGT]

Hello Guys, tuff things with my Panda.
I had a kidna malfunctioning left sife flashing indication, would flash normally once and then proceed to go fast without light.
Sometimes it would work normally sometimes not. So after a month it decided to blow up the transistor for the turn indicator flashers inside the bodycomputer.... Or thats what i thought !.
- Reading the schematics i see there is no fuse for the turn indicator flashers. So i said to myself, oh ow, the silicone chip ate the doo doo....I saw a little smoke from the driver fusebox (LH) and the whole car smelled like burn electronics.When it finished the show, the Right hand indicators stayed on forever like streetlights.

- So i break the chip clean the massacre. Now the flashes work without this chip, but no cabin light and the automatic door lock thinks some door is open and it doesnt lock, it opens everything again. ! Anyone that might know what this chip do ?

Here is the pcb carnage.

Photo three looks like a 25 amp double channel solid state relay


Something seriously went wrong, the are current and thermal protected, as well as loss of ground or power as well as reverse polarity

Photo 2 should be empty, just got very hot on the other side

Slightly different body computer

Good chance 1 and 2 are the same part

My guess is a ST VDN6????? Or equivalent

Letters looked like ST VNQ60** (asterisk where the burn was) but the outlook looks more like the ST VNQ660 its 5+ 5 pins

I can not confirm 100% as I don't have a spare body computer to double check

ST VNQ660SP is used in other body computers such as the Fiorino, so is quite likely

This post a year ago from a fellow member has the chip starting with VND6***. (check link below)

Also if i want to attempt a repair the problem is i have to desolder the whole vertical board to work under there. Also i bet it has welded itself onto the copper substrate need grinding out slowly if the pcb layers hold up... The other solution is to buy another board and transport all the IC's (immo, CPU, etc)
Which for me would be kidna hard never done it.

Fiat panda 169 Left low beam problems- body computer | FIAT Panda (Mk3)

Hello everyone, not a day goes by without my beloved panda malfunctioning. Today the left low beam stopped working. I figured the problem wasn't there because I had edited the front electrical wiring before. Cable, fuse, body computer sockets. Then I disassembled the body computer. hoping to...

Chat Gpt says:

• VND660 = 2-channel version
• VNQ660 = 4-channel version
  Both are basically the same "building block," but ST makes the VNQ-series when you
  want more outputs in one package to save PCB space and cost.

There's several solutions

1, Buy a replacement IC and pay a mobile repair shop to change it if you don't have the equipment to do it yourself

2, Buy another body computer with the same part number and pay someone to clone the replacement, not cheap here

3, Buy a matching ECU, body computer, dash, locks and keys, expensive but plug and play

No idea on cost or availability in Greece
