I have a NAR (Canada) Golf R MY16. I've been working to get ROW functionality with turn-signal activated, single-sided parking lights (SSPL).

While trying to figure this out, I encountered a few hurdles that encouraged me to explore the BCM adaptations a little further. It turns out you can tweak the parking lights such that they go off automatically on a timer, or before they completely drain your battery.

Here's a complete list of all of my changes:

(3)-After-run for park light-Bedingungen zur Parklichtbegrenzung begrenzen auf Mindestverfügbarkeit not active No timer limit.

I've studied the BCM adaptations for many NAR and ROW vehicles, and I believe this is the proper behaviour.

A few notes about the above changes:

  • I found channels 2 and 3 to be the ones that controlled the front double-U LED DRLs.
  • Channels 4 and 5 were already coded for SSPL function, but I couldn't figure out what they controlled on my car. I left the adaptations as is.
  • From DV52's giant spreadsheet of BCM adaptations, my car seemed to be the only one with (2)-After-run for park light-Bedingungen zur Standlichtbegrenzung and (3)-After-run for park light-Bedingungen zur Parklichtbegrenzung set to begrenzen auf Mindestverfügbarkeit. This limited my parking lights to automatically shut off after exactly 30 mintues. Figuring out how to remove this limit was the most time-consuming part!


This lead me to wonder about a series of adaptations, named After-run for park light:

(1)-After-run for park light-Bedingungen zur Beendigung des Standlichtnachlaufs not active
(2)-After-run for park light-Bedingungen zur Standlichtbegrenzung begrenzen auf Mindestverfügbarkeit
(3)-After-run for park light-Bedingungen zur Parklichtbegrenzung begrenzen auf Mindestverfügbarkeit
(4)-After-run for park light-Faktor fuer Verfügbarkeitstimer Faktor fuer x5 Minuten
(5)-After-run for park light-Standlicht-Nachlaufzeit 255 min
(6)-After-run for park light-Standlicht-Verfügbarkeit 6 s

The second and third channels have these options:

  • not active - The majority of ROW vehicles were set to this.
  • abschaltbar über Energiemanagement - "can be switched off on energy management"? I saw a 110TSI MY16 with this. Maybe something monitors the battery voltage and shuts off the parking lights before running completely flat?
  • begrenzen auf Mindestverfügbarkeit - Time limit. Several newer NAR vehicles, including mine, were set to this.
  • abschaltbar über Energiemanagement ober üder Zeit - Energy management or time limit.


The time limit ("Verfügbarkeitstimer") seems to be encoded in the next couple channels. My 7R came coded like this:

(4)-After-run for park light-Faktor fuer Verfügbarkeitstimer Faktor fuer x5 Minuten
(5)-After-run for park light-Standlicht-Nachlaufzeit 255 min
(6)-After-run for park light-Standlicht-Verfügbarkeit 6 s

Ignore the incorrect time unit on the last channel (6). The time limit can be set with the unit and multiplier in channel (4) combined with (6). In the above case, (x5 minutes and 6) = 30 minutes.

I've played around with Verfügbarkeitstimer and it allows you to set a maximum time limit after which the SSPLs will turn off. For example, Faktor fuer x1 Sekunde in (4) and 30 in (6) will have the lights turn off in 30 seconds.

Has anyone else played around with this?

Does abschaltbar über Energiemanagement actually work? I don't know if I have the time and patience to test mine!

What is the functional difference between Standlicht and Parklicht? I thought Parklicht described the SSPLs, but the Standlicht-Verfügbarkeit timer values seems to affect them.

What is Standlicht-Nachlaufzeit and why is there a default value of 255 minutes?
