Technical 500L Trekking 0,9L turbo problem

[dimi84]

Hello to all,

I have a 500L with twinair engine 105ps.
At last months when i am driving at highway and with A/C enable, the engine suddenly stop working properly like the turbocharger to switch off and goes only as atmosphere engine. When i pull the car aside and restart the engine, is working again as previous.
No any engine warning lamp has appear ever and the Multi ecu scan does not show anything relevant to this turbo “switch off”
Maybe anyone has faced something like that and can help me.

P.s. i allready went to an official repairer and said that the sparkplugs had problem so they change it. But still the same.

Thank you all in advance! ?

I have the same car and I had the same issue from time to time, the car was entering limp mode and did not accelerate.
Also no warning indications.
So I connected an obd reader and I got the P0236 error.
After a research I found out there was probably a problem with the boost pressure sensor.
It's a Bosch part with code number 0281002996.
I bought it 30 euros from any eshop easy to find it.
Also very easy to replace it only one torx screw.
So I did it and so far not happened again the last 2 months.
I will give you feedback for any news on it.
