Someone desolder the flash and read it out already.
I just don't have access to one of these. Otherwise I would have done it by now.

I've been working on a 04 TT cluster, so I might have access to the car. I'll ask the customer to see if I can read it out.

If someone send me their stock unit i'll do the leg work to get a readout. Very good with a soldering iron as well.

Kinda digging up an old thread here but trying to find a way to get more of a 50/50 split out of my tt. my brothers wrx is just much better in that regard  But found some intesting stuff looks like there is a way to monitor the system and possibly create some logs to see when its engaging and stuff. I need to figure out this can bus stuff first tho. also going to look at the option of a switch or something to the stepping motor that could still use the signals to the handbrake and temp sensor to disengage when needed. But anyways here' some info someone out there might wana look over. http://www.billswebspace.com/HALDEX.pdfhttp://forums.vwvortex.com/showthread.php?1765307-Haldex-Meter/page2 |

Bringing this back from the dead. Trying to use bootmode on the Haldex without success so far. Will post my progress soon. Has anyone else got further on this or have any information?

So supposedly the Haldex in the R32 and gen 1 TT uses a C167 processor. It also appears to 29F400 or 29F800 flash. They are tough to verify 100% as they are both bare die units with no casing. The dies are bonded to the pc board and then fine gold connections are used from the die to the PCB. The entire both is covered in a liquid bath, kind of gel like. The bare die pictures do look identical to the pictures given in there respective datasheets.
I don't have access directly to P0L.4 but I can make contact with DQ4 on the flash chip. However grounding the pin when applying power appears to do nothing. As soon as the low signal is removed from the pin the unit boots up instantly. Does anyone have any thoughts on anything else to try to access boot mode? I'd really like to dump the flash.

If you want to send it to me I'll desolder it and read it, then reassemble.

Desolder bare die flash with hair-thin wires sticking out? Really?
Gen2 has 29F200 so i'm guessing the Gen1 has that too or smaller.

I have to agree, there is no desoldering this part. Good to know on the 29F200. If I can get any kind of response from the CPU I am sure its readable. Need some sort of response first though. |

I have too compared photo of gen1 processor to several bare die models and it matches C167CR-LC.
When looking at the board, connectors facing upward, P0L.4 should be around lower right corner.
Propably would be pretty safe to test a few of those pins through a resistor.
Flash die seems to match to 29F200B.

The flash die didn't seem to match a 29F200 when I looked, the pin connections at the edge of the die looked different. I took some great macro photos of the processor and flash and can easily make out each connection.
