Title: Some fault code help...
Post by: dom on 07 July 2014, 22:23
Hey,

I've just bought an 05 plate Gti and gave it a quick scan with Vagcom, after clearing the old codes there are the ones that remained:

   Subsystem 3 - Part No: 1K0 951 177
   Component: Innenraumueberw.004 0101

1 Fault Found:
01134 - Alarm Horn (H12)
            004 - No Signal/Communication

The alarm horn doesn't sound when the alarm goes off nor when locking/unlocking the car (with chirps enabled), so I'm assuming that the horn needs replacing.

It's the 2 photo sensors that I'm stuck with....any advice would be appreciated :smiley:

Did it ever have the windscreen replaced?

Not that I know of, why do you ask?

Photo sensor is glued on it... I it was replaced and old cam stripped of the old glass and glued back onto new then chances are it may have gotten damaged and may also not have been calibrated.

I thought that the photo sensor was on the dash by the centre vents, or is there another near the rear view mirror?

I think it's on the windscreen behind the rear view mirror. It might be worth seeing if your intermittent wiper setting still works as if the windscreen has been replaced, the rain sensor function will also likely be faulty if this wasn't replaced. Least then you know the reason for the light sensor!

I assume you've tried setting off the alarm to see if it does work?

Cheers, the windscreen is the original as it's stamped up in the bottom corner. I'll try the intermittent wiper setting in a minute.

I've locked the car with the drivers window open and waved my arms around inside to set the alarm off, the indicators flash but there is no siren. I've also enabled alarm chirp when locking/unlocking the car via vagcom and this doesn't work either.

photosensors are by the dash vents the rain/light sensor is on the windscreen thats something different. The faults show intermittent did they not clear dom?

Cheers, that's what I though. They aren't clearing at all, I've had Vagcom on it a few more times since to enable various things and to code in the cruise control. Each time I've cleared codes they've come back immediately, is it something you've come across before?

Every day's a learning day, cheers for that. Could the sensors in the dash need replacing?

nope not seen that before. the fault is picked up in hvac so though must have something to do with the aircon. pm me your vin or reg and i'll do some digging at work tomorrow if i get a spare 5 mins.

could be a dicky sensor but if you fancy checking i've just pulled up the wiring diagram

so from the sensor

pin1 is a red/green wire goes to pin 9 of the 20pin connector on the aircon unit
pin2 is a green/purple wire that goes in to the L9 connection which is pin17 of the 20pin connector but it also taps in to the left and right vent temperatures sensors which then go to pins 13 and 14 respectively.
pin3 is a green/black wire that goes to pin 3 of the 20pin connector on the aircon unit
pin4 is a green/blue wire that goes to pin 1 of the 20pin connector on the aircon unit

hope that helps!
