hi Guys,
my control unit hanged again. I suspect water damage.
now I have to buy a new one. I have a good offer for a passat 3b 1.8t me7.5 with the part number: 4B0906018DH and bosch number: 0261207928 to get. I would also love to strike, but would it work at all? could I transfer a golf 4 / audi a3 me7.5 dump to this control unit and it would work or are they very different control units?
I have everything for the rest of the conversion from m3.8.3 to me7.5. only I have not found a golf 4 / audi a3 control unit which is comparatively good and cheap.

aaa understand. and there is no way to change the boot version? is there a me7.5 from the audi a4 or passat that has the same boot version? As far as I know, the pin assignments are the same as for the A3.

Dude the bootrom is OTP. Yes there is a way to change it - replace the main processor with a new one! For all intents and purposes NO. Also, on transverse engine platform you NEED to get a waterproof sealed ECU, because it gets rain on it. A 4B will never ever work, because it's not protected in any way, it won't fit the bracket and it is designed to be housed in a weatherproof box. |

the control unit should enter a golf 3. Since I already have water damage, I decided to pack the control unit inside. therefore, this shouldn't cause any problems. The only thing according to your generous information would be the bootrom. if I can do that simply by swapping the main processor, it wouldn't be such a big problem.
such main processors do not cost the world now or do they?

Currenty i tested last week CG passat ecu crossflashed from 2.0 N/A ALT on AMK engine cuz it was with ABT tune wokrs great , but they differ hardware one is not water resist (without sealant on edges) and it uses diferent case it will be hard to fit. DH will not work i think it uses newer processor if im not wrong.

Wait what , you flashed a NA tuned file on 1.8T me7.5 hardware? Did I understand that right lolz |

As long as they have the same bootloader you can cross flash.
You should also move over the eeprom dump.
You can find the bootloader version with me7check.
I put an ECU from an A4 in my Golf, just added some black silicone around the edges to seal it. Works with no issues so far

Replacing and programming a such processor is strong three digits labor, the processors are probably discontinued. If not, the chip will cost more than an ECU. What's your obsession with this? A proper ECU is like 25-40€ on eBay. |
