I have a 2012 Volvo VNL 670 and after 12h of idling the truck would do a 20min regen by getting the RPMs up. After 20min it shuts down, and then after 20min off it starts again. And keeps doing the same till I start driving. It has a clean filer, DPF and DEF, new Turbo new Catalist. I took it to Volvo and they changed the Catalist few clamps and $5100 later same problem. The truck will regen when driving just fine, its only the parked issue. I did notice my Temp usually doesnt go past 190 degrees so I bought a new Thermostat. Asked another mechanic if that could cause it he said maybe. But anyone has a similar issue? And as its colder now it starts every 8-9h of ideling before the RPMs go up.
2012 VNL670 keeps doing parked regens

Isn't a good idea to idle the newer trucks...Idling causes def filter to clog quicker....the more times a truck regens while parked the harder it is on the engine due to the extreme high temps during parked regen

Have you checked the 7th injector? Has it been replaced? Any codes coming up?

I have Webasto for heating, it's quite affordable , around 1500 $ installed , have to save for some some sort battery powered AC and minimize idling. -

I dont know, i was driving on I-30 W in Texas all good running shooth, was late night got tired pulled over on the ramp at exit 178 to take a nap , idling for AC. After 2-3 hour i woke up by a loud banging, scratching noise coming from motor, right under the dash. I understand the idler gear gets lose from shaft and starts chewing the block or rear timing gears cover contaminating the oil and entire motor with metal shavings, interesting it didnt happen while driving.Last edited: Nov 13, 2018
