this "feature" came from the factory :(

on the first dealer visit i were sent away,

they told me it's all ok and some bullšhit about regeneration.

on second visit dealer found too high pressure in cooling system,

decreased it and problem were gone for few months.

then it returned and dealer repeated decrease pressure,

but now it helped only for two weeks.

on fourth visit they reflashed newer firmware of cooling system -

still not solved :(

My one does not do this.  I take it you have the Air Conditioning switched off.  If not, see if that makes a difference.

 

You mention that the garage reduced the pressure in the cooling system twice as it was too high.  This would worry me as this can be caused by a blown head gasket.  It is easy for a garage to test this, have they??

another guess that can be connected to temperatures under zero

gone since 20.jan (service were on 13. Friday)

 

 

solved on fifth attempt by replace 5Q0959126A

What does that code represent and what was exactly the defect ?

nr.16  pressure sensor, refrigerant line
