Seat Leon 1P0920827 pointers not working

[mislav88]

I have here a Seat Leon 2008 with half-dead cluster. All analog pointers are dead, while all the rest works ok (also tested with output tests with vas and vcds).

Cluster is
1P0 920 827

I heard that this cluster is not cryped, so i can just swap eeprom to the new dash, is this true?

[leandroks]

changing the eeprom should work ok. have u had a look if there is any rust on the internal plug???

[mislav88]

it it is not internal cluster fault pointers should move in output tests, right?

also two pointer motors looks like they are burned (black smoke traces on white plastic), but resistances are ok on all four (approx. 145ohm)

[leandroks]

Yes they always loook like burned it is normal, have a look on the processor soldering, some seat has bad soldering points.

[mislav88]

you mean to check micronas mcu soldering?

[leandroks]

On seat make it happened on some dash lots..

[mislav88]

resoldered mcu and it work now, but i broke one pointer motor, if someone has one to sell please contact me in PM

[leandroks]

I am happy it works, it is a very commum problem on seat make...

[mislav88]

now temperature pointer shudders about 5 seconds when i switch ignition off, otherwise work good. same happens no matter how i rotate motor positions

[leandroks]

have u tryied to rotate it many times clockwise???/

[mislav88]

i tried swapping motors from other dash, tried few of them but always the same thing happens
