• Toughest car ever made 4 Oct 2016 (Forum)
  With all the talk of costly failures on modern turbo diesel cars. DPF, DMF & premature turbo failure, I'm hankering back to a simpler time. The days when a simple well maintained Diesel engine could cover massive mileages with little grief for owners. I've been in a Nissan Bluebird 2.0dLX

  this would seem unlikely. I have read reports of DPF sensor but the engine is not fitted with a particulate filter. Other comments have been the ERG valve whatever that is.   Many thanks for attention Robin Grimmett

  at  JLM PAT fluid DPF Cleaner. It says it replaces  EOLYS 176 and DPX 42. Haynes manual mention that EOLYS 176 and DPX42 are not mixeable or interchangeable so wondered if that EOLYS replacement can really replace both, hence asking if anyone has used it.
