Back in 2010 I drove a late model BMW E60 M5 on a cross-country road-trip. This is when I first discovered the "Komfort Blinker" feature that BMW had added.
This feature allows you to momentarily tap the turn signal lever left or right and you get three successive flashes from your blinkers.
This makes signaling for lane changes a bit nicer.

Here's a cheesy video for you, but it demonstrates this perfectly.

  If you think I'm just lazy, you can continue to pull and hold the lever when changing lanes or passing or maybe never use your blinkers. In my opinion, once you try this you'll agree it's a nice feature. 
This feature later became standard in many new cars, including my Subaru, so evidently it's pretty popular too. 
I liked this feature enough that in 2010 I decided to figure out how to make this work in my 240. 

I did some research and discovered Volkswagen and Audi also began adding this feature to their cars beginning about 2006. 
These cars use a small simple blinker relay, VW or Audi PN 000 953 227A (or 000953227A).  After obtaining one of these relays on-line (cost was about $60 shipped from Germany in 2010), I set out to discover how it functioned and to find out if it could be wired into my 240 blinker circuit.  This took some studying and experimentation, but I was successful. 

If you have trouble finding PN 000953227A, the relay is also available as of 2023 in a kit numbered as PN 000998229A.

Installing this relay into my 240
makes the blinkers work exactly the same way as the BMW, VW, Audi or any new car with this feature.  It does not affect the normal operation of the blinkers or the emergency flashers. Nothing is removed during installation. Just the new VW/Audi relay is installed with a few wire connections to existing wires.

My 240 now does the 3 flashes when I tap the blinker lever. A pleasant surprise I also discovered was that if I hold the lever for about 1/2 second I GET 4 FLASHES.  I don't know if that's an intended feature in this relay, but it works this way in a Volvo.

I created a diagram below for those of you who want to do this in your own Volvo
The VW/Audi relay has five poles, just like a standard 5-pole power mini relay. Connecting it to the blinker system is as simple as splicing FOUR wires into wires from the dash emergency flasher switch and then connecting ONE wire to ground. 

This operation might also be just as successful in any Volvo 700 or 900 series, or in nearly any car (probably any European car) that uses an emergency flasher switch and a blinker flasher relay similar to the Hella 3-pole flasher relay shown above

After success with my Volvo, I also installed this mod in a 1988 5-series BMW (E28) for someone else. That diagram is shown below also.

This Volvo mod was completed in 2010.

I also did this mod in a 1988 BMW M5 (E28) and it was successful. 

Installing this relay into an E28 BMW
makes the blinkers work exactly the same way as the newer BMW, VW, Audi or any new car with this feature.  It does not affect the normal operation of the blinkers or the emergency flashers. Nothing is removed during installation. Just the new VW/Audi relay is installed with a few wire connections to existing wires.
