XZBMW  6WA Kombi - R270 eeprom erase
Hi,
Someone got a problem with some clusters 6WA when eeprom erasing using R270 ?
I have the problem with two Kombi: 6WA F20 and 6WA F10 (from 2013/2014). When I read 160DXXX eeprom, I have a file with 80808080.. in all bits.
I can change some bits, then write without error, but when I read again the eeprom, I don't find my changes - again only 808080.. everywhere.
I also tried to write a complete file from another 6WA, but I have an error in the bit 1F.
Your ideas please ?

No, I use a clip to connect directly to the eeprom on the PCB -
Works fine with other clusters (Kombi an DKombi)

Thats true - works fine

But the last cluster i had, i cant over-write it - than i had desolder the chip and put it in the Socket - than the flash was successfull
