Could anyone please advise me regarding a retrofit on a Volkswagen t5 mk 2 van (2015) .
The situation as follows-
I have retrofitted rear passenger A.C .
This has necessitated the need to change the driver cab heater control unit (j301)for a model that has an additional rear switch , which now sends power to a separate rear( roof liner mounted )control unit .
Apart from the additional rear switch it is similar in design .
In fact the retrofit functions and no error messages appear using diagnostics , but i do have a minor issue ,as follows-
The temperature control on the j301 does not operate correctly and only delivers heat when in the fully open position .When the dial is in in the coolest setting position, the hot air flap is closed(normal) ,when in the middle position the flap is still completely closed . The hot air flap begins to open and only FULLY ,when the dial is in the hottest position
Also i can see what is happening from observing flap motor and lever through a gap in the dashboard .
I have followed the instructions in basic settings (as per Rosstech instructions)for resetting flaps ( showing as completed ) with some improvement and have also tried the option compressor "run in /automatic "-(error message shows up) - so no luck with that .
However I am a little confused with all this.
Do i need to recode for the new heat control unit or does is it automatically recognised ? if necessary to recode how do i obtain a code ? is there a method of knowing precisely, if the flap and motor are responding correctly with the correct temperature?

thanks for all replies and assistance

Please post an Auto-Scan for context. I understand that there are no fault codes, but a scan will show people how the vehicle is equipped and configured.

Hi thanks for the reply

I have checked the heater control VW part n0 against the n0 featured in the RossTech app scan info and it appears to be correct ( which means that it has recognized the control)
However As a result of messing around with the settings, I now have no AC. ( and this now shows as an error on the autoscan )
as mentioned previously -the auto flaps reset in basic settings is showing as completed but the compressor run in shows up as an error

Unfortunately the Rosstech instruction/options s from the' golf 5 climatic' page differ slightly from the options available in the App. so it is difficult to understand what to do

information requested below
maybe I should contact you(rossstech) via phone?

We do not do retrofit support over the phone, sorry.

Moreover none of us have any personal experience with retrofitting rear A/C (or anything else for that matter) in a T5 because the T5 was never sold in the NAR market. This is why we still keep a T4 as our company truck! :)

There are 2 different basic setting available for "AC Compressor First Run-In"
Test it, I would let the engine running at idle.

ok thanks
thats either the manual or automatic option
i have only tried automatic as per instructions on the rosstech VW Golf (5K) Climatic webpage
and as mentioned previously an error message appears
( worded -"conditions not correct or request sequence error")

The adaptation option which is recommended if an error appears , is confusing and i do not understand the 120 part ( extract below )

I guess that the issue must be something simple because the compressor worked fine before i started fiddling with the Vcds app
and the only difference with the old heater control unit is the additional rear control switch

Any advice appreciated


AC Compressor First Run-In
Necessary when the Climatic control module (J301) is replaced.

Prerequisites to start the basic setting A/C compressor first run:

  • Engine at idle
  • Transmission in Park or Neutral
  • Do not cycle the ignition
  • Basic setting was performed for the flaps
  • Inside blower motor is switched on
  • Air vents fully open
  • Load management not active

"AC Compressor First Run-In" Steps:
Start engine and allow it to Idle.
Adapt flap end stops as described above.
[Basic Settings - 04]
Select IDE02259-ENG167462 "Compressor run in: automatic start" from the drop-down list.
[Go!]

  • It will show completed, but wait 120 sec (2 Min) and observe the flashing A/C button light on the HVAC panel.
  • After the Basic Settings has completed, the A/C light will quit flashing and the fault code will clear.
[Stop]
Note:
If Basic Settings reports Error the module may need to see an Adaptation change before this can be completed. Go to Adaptation and change "Driving time for compressor run in" from 120 -to- 120 and save it followed by repeating the entire procedure.
