Heated seat issue

**SR123** · 17-04-2020,12:23 PM

Hi,

I bought a VW Golf mk5 GT TDi (BKD engine) about a year ago. It has early Jetta mk5 TDi Sport heated seats installed (I think that's what they are) but never enabled on VCDS. After cracking through a load of jobs that my new found time at home has allowed me, I enabled the heated seats using VCDS but they still don't work. The error VCDS has thrown up is: '02092 - Enabling Heated Seat, 009 - Open or Short to Ground'. I've been on the RossTech wiki (http://wiki.ross-tec...index.php/02092) and it doesn't really help. I've searched the various forums over the past couple of days with no success.

Checking the plugs under the seat, I noticed on the drivers side the seat loom (male end) has 5 wires going into the connector, the connecting female end has 6 wires going into the connector. (The passenger side is different again with 5 on the seat end and 3 on the female side).

Does anyone have any golden tips to suggest?

Also, I want to rule out the connector wiring anomaly - please can someone post a photo of their drivers side loom wiring loom (under the grey sliding flap under the seat). I've attached pics of mine to help compare (although they're flipped to one side for some reason!)

Cheers,

Scott

Have you checked the 3 fuses for the seats I have the same car and fitted mk5 gti seats a couple of years ago

What's the build date for car? Looks like wiring changed in Nov 2005, and that plus earlier Mk5 variant appear somewhat different to Mk4 on first glance.

Yep, all 3 fuses are fine.

Are you able to take a pic of your wiring loom by any chance please?

The V5 says date of first reg is Dec 2005...

A six-position connector with white, blue / white, blue / black, red / yellow and brown pretty much matches the May 2005 Mk5, but diagrams also have a purple wire on them which looks like it takes current to heating pads. And the positions seem to differ from what's indicated as well... So is that a picture of what was already in the car?

What colours are on the seat side?

So the seat side is as per the first pic, which pretty much matches the colours you mentioned. The female connector that the seat loom connects to (which presumably goes under the carpet to the fusebox/dash switches) is as per the third pic with: yellow, blue, white, red/white, brown/blue, blue/yellow.

OK, starting to make sense after realising forum headings here, Wikipedia, etc differ on what a Mk4 Jetta is. I'm assuming donor car was early Mk5 Golf equivalent based on those seat side wiring colours, but may become clearer when I look at diagrams again...
