went on a long trip today and i noticed that the car was feeling a bit chilly, anyway after some fiddling i noticed all of the left controlled vents are blowing cold air regardless of the temp setting, the right vents operate as normal. any one had this? gonna plug in vag.com tomorrow to see if it has noticed
Im thinking a thermostat?

Hi Mr mills
Is your vag com cable a ross-tech one or is it a copy as I have seen them on ebay quite cheap but they will only use up to 409.1 software, will this cover the problem with the heater as I also have the same prob and would like to have a go at fixing it myself.

Tom.
mine is original hex + can + usb. I was looking at copies but didnt want to risk it on the treg. Also they have reduced functionality, low software (as you mentioned) iam running V 904.0 which is quite a few up on 409.1
and no tech support. I have asked multiple questions to rosstech about the treg and they have always been useful. Add that to the money i'd save in dealer diagnosics and its the best thing ive bought.

from your pm:

dont know the differences between V409.1 and now so not sure if it covers what you need.
I would think its unlikley to be the climatronic unit itself. The motors are prone to failure and match your issues.

Sorry to bring this back up but having same problems with my Treg, bought Vagcom and getting 01809 v158 code and 00710 V107, motor faults.
Done all the test from page before and value stays stuck on 179 not matter what input is set, so need motor and to replace it.
Is this a DIY job or am I best getting a Indy VW specialist to do the job, any recommend one in Wigan area?

Thanks in advance for help.

JS if you still got the dash removal info could I possibly have a copy?

Cheers

Great doc with good diagrams - but I'm even more glad I simply paid my dealer to do the job!!

sorry to revive this thread but my initial link to the documentation no longer works and another member has requested it. To hopefully help others I have re-upped it here.

Its been a long while since I've been here since I sold my treg, nice to be back... even briefly.

Enjoy.!
