Dear people! Someone is familiar with the heater from the Volvo s80 D5. I changed the burner unit in February through an entire new unit (Feb.2014). Then the heater did not run very often anymore, since it was already warm and it was no longer necessary to switch on due to the temperature. Now that it is cold I have noticed that the heater does not start again. Was then today at the friendly and had the error memory read out and the servicepak 2.0 charged. Then the mechanic tried to start the heater over the laptop, you could hear how the device turned on it smelled a little bit like diesel but the unit didn’t ignite, after a minute it went out again. We tried this procedure twice, but nothing did happen. Furthermore no exhaust gases came out and the pipes didn’t get warm either! What could be funny about it, that no error was spitted off!?
