[Solved] Peugeot 508 SW 2.0 HDI 163HP AUTOMATIC Emergency mode of the gearbox

Hello,
Maybe someone knows what happened. Yesterday I turned off the engine with the gear lever in the "P" position. After a few minutes I wanted to start the car and it started:
- an engine fault message was displayed
- and then after 1 sec. the message "gearbox damaged, repair the gearbox" was displayed
The car starts without a problem, only when you try to engage the gear in "D", the lever moves with a clearly perceptible resistance as if something is blocking it. Then there is a powerful jerk of the wheels as if there was play on the axle shafts. Up to that point the car had performed very well. Today I will be connecting from PP2000 to it, only then will I know something more "knew the fault code". In addition, after switching on "D", the gearbox only works in 3rd gear in emergency mode. The car has traveled 200,000 km on very long stretches. Anyone have any ideas, suggestions, or maybe already encountered such a case. I personally read somewhere that the flow meter may be the cause and that is why the information about the engine fault appeared first and then the gearbox went into emergency mode.

Regards and hope for some information.

The gearbox can enter emergency mode due to such prosaic things as, for example, a failure of the ABS sensor - it's dirty for me and it gives me a hard time from time to time.
But without a diagnostic device, he can't say anything.

Thanks for the information,
As I wrote today, it will turn out what is my steed
Later I will write what errors are detected and I will look for a solution, hopefully without visiting the workshop (I mean it's some kind of sensor or other crap that can be replaced by yourself).

Regards.

Welcome back,
Yesterday I made a PP2000 scan and after detecting almost 20 fleeting errors from the error of locking the door, blocking the left front wiper and engine and transmission faults that disappeared after a 14-hour stop. I came to the conclusion that it could be either an ABS sensor or a battery on the finish or tarnished contacts on the CAN bus (I had this situation in Berlingo and only then the horn did not work for me. Because after erasing the errors and driving almost 200 km, the errors do not return Soon I will test the efficiency of the battery at a friend's workshop and, by the way, I will lift the car and look at the wires to the ABS sensors. Then I will let you know.

Hello

I have a similar problem with the fact that while driving fast (160 km/h and covering about 500 km) I had a problem with the gearbox locking in 3rd gear. Before locking the gearbox while driving, there was a characteristic jerk when driving, and then it blocked my gearbox
After waiting a few minutes the problem disappeared. I noticed that when driving calmly about 130 km / h, there was no problem at all. I found somewhere that it could be a valve body. But I didn't mention it, so please take it as a hint.

Aso they told me that I can change to manual (in emergency situations, e.g. on the road) and it should "help" I had such a situation and I managed to drive at low speeds and with changes to lower gears 3,500 km :)

If anyone knows anything about this topic, please let me know

Hello
I have a similar problem Peugeot 508SW 2.2 GT automatic. For some time after a long drive and warming up everything, a jerk is felt when getting off the 4th gear, and there is a very strong jerk when starting, for example, from traffic lights or when maneuvering front-back. When starting from the lights, there is no problem as I switch to N when the car is stationary, and before moving off I throw D.
Diagnostics does not show any gearbox errors, The problem appears only when the engine is warmed up and a long drive.
The mileage is 75000 km.
Please let me know if anyone found the cause and solution?
best regards
Bart

Hello
I have the same problem as the bart201 also on the 2012 508 SW GT, except that my mileage is 124,000 km. I've had the car since new so the mileage is true. The same is true when starting at the lights. If I'm in D mode at traffic lights, there is a jerk when I take my foot off the brake. if I switch to N earlier and go back to D then there is no jerk. I also noticed that when I slow down and shift from 4th to 3rd gear it starts to jerk.
If anyone knows the reason, please let me know.

Hello
I have the same problem as above - Peugeot 508 GT
After warming up, the gearbox jerks when downshifting from 5th to 4th gear and when shifted to D
there is also a whisper. Sometimes it's strong, sometimes it's weak or it's not there.
This is often associated with driving quite fast.
No errors are shown on the service computer. What it is nobody knows.
The worst thing is that I've heard in a few places that if it doesn't break down for good, nothing will be done. What I did was change the oil in the box, I checked all the contacts in the plugs related to the box. What I suspect is something is happening with the solenoid valves - they control the box wrong. And the computer probably will not show this type of failure in the first phase. I draw these conclusions because I had a similar problem with the automatic transmission in the Honda Accord - it jerked for a long time and there were no errors. Only at the end, when it was completely gone, the fault lights came on. But I emphasize this is just my guess and looking for a reason because it is very annoying. I also read that many electronic trifles in this model can cause such symptoms.
If any of you know a solution, please let me know, maybe we can track down the culprit of such problems.

The Peugeot service is already aware of this fault. The manufacturer claims that the cause is worn clutch discs in individual gears. In my car, I reprogrammed the solenoids that control the gearbox, but it did not help. The manufacturer recommends replacing the gearbox as a repair. Personally, I also did it, and I bought the gearbox with built-in valves on the auction site for PLN 1,300 and the topic ended. Of course, you can repair the box, but this solution can be more expensive.

Thank you for your answer.
Yesterday my mechanic friend also mentioned to me that it could be the clutch fault.
In Peugeot they were not able to say what is, they only reprogrammed my gearboxes like yours and nothing. So, however, replacement - it's hard, it's not a very durable car.
Thanks again for the information

Hello
Yesterday, after replacing the timing belt and oil in the gearbox and engine, my friend and I connected the computer to the car. There were 4 bugs in the chest that were defined as temporary. They were all related to relays and electronics in general, e.g. weak signal from the relay, interrupted signal from the sensor, etc. Unfortunately, I did not write down what the errors were, so now I will not write exactly what. After deleting the box worked great for 30 minutes. Only after a strong warm-up did it start jerking when shifting from 5th to 4th gear, and when switching on D. But it is much more delicate than before.
I am going to a specialized electronic service to accurately write down the errors and specify the individual elements and replace or correct the contacts. There is no doubt that the jerk when downshifting is rather worn clutch discs, but it is probably worth reviewing all the little things before starting specific replacements - it's always lower costs at the beginning. When changing the oil in the automatic transmission (very simple), it is worth resetting the gearbox counter at the end to change the parameters to the new oil - there is a difference. Not all slot machines know about it. Also, watch what oil they replace (first of all, the color - it must be the same, the parameters are required) and only replacement by pouring from the top, no combinations from the bottom. You definitely need to review the ABS sensors because it also shows such information. We'll see what comes out. I will definitely not go to the ASO service because they mow evenly and will not do anything. The cost of the oil is PLN 189 and it is exactly matched and the replacement takes 15 half an hour. PLN 700 in the service
Regards and keep fighting

Unfortunately, the easiest and most effective way is to replace the gearbox. I bought a used one at an auction for PLN 1,300. The exchange solved the problem.

Thanks for the reply - that's what I do and replace on Thursday. I got the box for PLN 1050 complete.
I'm tired of this fight, although it doesn't jerk terribly and sometimes nothing at all. But I don't want to play it anymore.

The car has been sold.
