Nothing special so far. Controller is suprisingly easy to open, you only need sharp knife and a screwdriver. I also have a gen1 controller, but by the look of it, it's bare die processor doesn't match the c167 bare die model.
Gen2 processor is C167CS-LM, flash 29F200BB, eeprom M95080. So quite simple to read&write in bootmode.
Needs testing whether there's possibility for CAN bootloader, since there's no K-line.

You need to add an external serial circuit to use the bootstrap loader on Gen2, no CAN bootstrap loader is supported.

Guys,
I have a Haldex blue, but you're bamboozling me with all this electronics stuff. This is off topic, but I thought I'd throw in the question because clearly this thread has the eye of several people who are very knowledgeable about Haldex controllers.
I would like to be able to directly log/measure or indirectly infer/derive the torque splitting activity of the Haldex controller as it is distributes torque from front to rear when conditions change. I previously asked this question on a non-technical forum and didn't get a definitive or satisfactory answer.
Is there any way to do this via ECU parameters over OBDII do you know?
Thanks in advance.

A person told me that a Spanish enterprise, changes the haldex controllers... It's located in Bilbao but I don't know the name of the enterprise.
Till now I haven't seen one good option for the blue haldex, it's the only reliable haldex controller.

I'm certainly pleased with mine, although the effect for around €700 is subtle. The owner of the local specialist I use (who supplied and fitted my blue Haldex controller) was quoted in the April 2006 edition of Audi Driver magazine as saying this:
"When you put a TT or S3 on the four-wheel rolling road, you can see that the drive is shuttling back and forth between the front and rear wheel. At steady speeds, nearly all of it goes to the front wheels. With the controller, which comes from Haldex themselves, there is a much better balance between front and rear drive, as well as the handling being improved."

Gen1 measuring blocks are quite limited (only 2 bytes over CAN), so no win over there. Propably would be possible with software like setzi's logger in ME7, but you'd need original flash for that. I don't know if anyone have successfully extracted that yet. My gen2 experiments are in a jam. BSL and CAN communications are up and running. I don't know how to proceed with CAN reading/programming tests. Cannot get the unit to respond to anything i send. |

O.k. thanks, that's confirmed what I thought judging by the limited parameters available in VCDS and nothing I've yet come across in ME7 documentation.

hey ttqs ... do you have pictures of the blue haldex controller opened? to see the differences between an original and the blue one???
it must be possible to mod an original one...

I am 99% confident that the only differences are in the code. It be nice to get a copy of both and compare. Although without any definitions we would just be staring at code blindly.

Sorry, no. I never even set eyes on the thing. The garage I used supplied and fitted it for me. I would also say with some certainty that the only difference is in the code that controls its action. The main difference being the pre-X function which is only a software modification. Otherwise, it's an identical plug 'n' play unit apart from the colour. TTQS |

Dont be so sure about that.. the blue controller consists also of an "upgraded valve-package" according to the haldex people themselves here in sweden.. i havent pried my blue one open, but i fitted this one myself, and the housing is a bit different, so their statement makes sense imo  i have the standard unit here on the shelf tho.. ready for dissection..  |
