ska_abbas Posted December 21, 2022 Share Posted December 21, 2022 Hi all, I have Nissan Qashqai 2015 Ntec+ Diesel and the other day the engine management light went on. I took it to the garage and he used the computer for diagnosis and it turn out 'Thermo Plunger Relay' error. The garage guy wasn't sure about what it is, and said it could be the DPF.... Has anyone encountered anything with Thermo Plunger, what its job is, and how much does it cost to replace it? Any advice would be highly appreciated Thanks Link to comment Share on other sites More sharing options...
Trevor Posted December 21, 2022 Share Posted December 21, 2022 Not sure the diagnosis is anything more than if it is the DPF then it is best to give the car a good blast to clear it through and at zero cost Link to comment Share on other sites More sharing options...
ska_abbas Posted December 21, 2022 Author Share Posted December 21, 2022 The guy advised me not to go on motorway in case the issues escalates and DPF would become problematic, which is a major cost. However, I read on internet that if you drive at 60-70 miles for 30-40 minutes, the DPF usually clears itself Link to comment Share on other sites More sharing options...
Trevor Posted December 22, 2022 Share Posted December 22, 2022 You are correct with the latter, always worked on every car I have had a DPF issue with Link to comment Share on other sites More sharing options...
