My V40 2L Turbo built in 2002 has the problem that it often runs out in idle. If you turn it on, you have to wait for a few seconds and watch how the stationary gas settles in. First it is over 1000 u, then it falls off until shortly before, then it goes up to a normal measure at about 700 u again and stays there. If you do not wait for this procedure every time and starts immediately, you can assume that it runs out of the next idle. That’s annoying because you are used to turn on and start driving. Can it be that the engine control unit has lost the long-term memory (Alzheimer/Dementium)? Besides, the central locking only goes with the key into the driver’s door lock. Neither the radio nor the button in the interior solve the ZV. Can it all have to do with the engine control unit or, someone knows what comes into question? The workshop of my trust has first waved off and I said to the Volvo dealer. I would like to get some tips first.
