May14

Problem:

Trying to make a key for a 2019 VW Polo, Normal key not proximity. 5C chip. Tried using both adapters that are in the shape of the key. Lonsdor K518 failed to read original key data with MQB49 5C adapter

It reported an error” Data reading failed. Error code Unlock failed ret=25″ Any solution ?


Solution:

Check the connection diagram carefully. You need to solder one wire from the key circuit board to the 5C interface board, as shown in the diagram. They try again, and it should work.

Not for all key types. For this type of key, solder 1 wire to the board.

If reading the original key data for BMW BDC2 or BDC3 fails(error code 25), check if need to solder 1 wire to the board as well.

Flex Failed to Write PSA SID807EVO by OBD Solution

May7

Problem:
Magic Motorsport Flex programmer reads Peugeot 307 SID807EVO ECU ok, but can not write the modified file by OBD. It is a keyless system.

Error autohrization from ECU failed.


Solution:

The keyless ones have to see the key in the emergency key position to allow operation.

Key must be in a coil detection area, that is why you couldn’t read.

Put key in the correct compartment and try again. Put key in the slot beside the steering.

Also if manual put it in 1st drivers seat belt on and hazards

Optional Solution:

Try leaving the ignition on even when it asks you to turn it off, or disconnect the battery for a while and try again.

Play around with ignition on off timings. Don’t wait for flex, when it says ignition on click ok and then wait around 5-5 seconds before you turn it on. If you’ve done any resets with diag make sure ignition off for 2 minutes before you connect flex
SID87 EVO if password protected can be done obd, if non password protected boot only,, should still connect to update to latest software.

User feedback:
Disconnected battery for some time did the fix and worked
