Peugeot 5008 2019 strange behaviour

[kingpatrikro]

hello, have a Peugeot 5008 2019 1,5 diesel, 186 k km and sometimes when im driving all the errors come all at once, first it appears the check engine- gearbox fault, esp/abs fault and so on, i can't change the gear but if a stop the car for 10 minutes and then I start the engine only the check engine light is on but the cars works perfectly, what can it be?I think that it might be a sensor

Is it an automatic gearbox ?

[kingpatrikro]

yes,8 speed eat8

[kingpatrikro]

Is it an automatic gearbox ?

8 speed automatic

[northrol]

Maybe a faulty solenoid on the gearbox?

[kingpatrikro]

I really don't knows, but I just discovered that if I go beyond 130 km/h the errors starts but if I drive like 100 km/h everything its ok

We had a similar problem on a previous 2014 508 and it was ultimately traced to a corroded ABS fuse and fuse carrier.

It started as intermittent but became permanent with ABS/ESP lights, transmission fault warning and the transmission going into limp home mode. A new fuse and removal of the fuse carrier sorted it.

I know auto transmissions rely on various sensors for information, including wheel speed, so it could be something along those lines. Possibly related to a failing wheel speed sensor, which would certainly deactivate the ABS/ESP, which in turn might then result in the transmission selecting 3rd as a failsafe in the absence of correct wheel speed information.

Have you had the codes read?

[kingpatrikro]

yes I have 17 pages of errors

It would be worth attaching the codes for others more knowledgeable than myself to view.

Have you deleted the codes and then scanned again to see which come back or are permanent?

codes are not permanent:((((

[508Allure]

So every one of those codes can be cleared until you are driving at a certain speed and then you get the dash warning lights, transmission stuck in 3rd gear and the exact same codes return?

Have you disconnected/reconnected the battery recently and without carrying out the correct BSI reset procedure?

[kingpatrikro]

I haven't touched the battery and the gearbox sticks at a random speed like 7 th gear or 8th gear not only on 3th

today was the first time testing the car at a guy that is running expensive sport cars and he alo do chiptunning and things like that and he is a pro,i need to go a second time so I can compare the errors

here is a link with the only clip that I made about this errors was driving on the highway and after 10 minutes 130 km/h autopilot that's what is happening:
