New to BMW’s but not to diesels. Just acquired a 318d that’s clocked over 145k miles however was a company car so FSH and very well looked after. The car is now only used to bob around town and very rarely sees a motorway. The particle filter light has since come on so I went for a 40 mins motorway drive doing a steady 55mph in 5th gear and nothing??? It’s now booked in for a forced regen however I don’t want to have to keep doing that!! How come the motorway drive didn’t do the trick?

Morning Keith

My sons Toyota pickup gets this from time to time the Dealer told him that it needed engine revs at 3k for 15mins minimum to generate the heat required in the DPF. Even in his truck that means 60+ in 3rd gear. The other thing to check is the EGR valve and all it;s pipework.

      BMW 318i boot locked can’t get into

      Update: I checked my battery and it charged in 5 minutes, so I don't have to find another alternator. All seems to be OK except for the plastic "L"s with a short rubber hose that bypass the HV/AC solenoid. Those get clogged after @ 150,000-190,000 miles (if distilled water wasn't used) and cause air pockets that try to burst radiators. I have a few more brass "L"s, so now I can throw the plastic ones away. I have to be careful I don't fog the windows though, without heat or cool.

      105C thermostat replacement

      You are absolutely right. The strange thing is that when I put the chassis number on the realoem it shows that the temp sensor is not applicable on my vehicle. I will physically check for a sensor. In the meantime, do you think that the removal of the MAP activated thermostat will effect the temp gauge on the dial instrument item 6? I am tempted to add a dummy resistor , 11.5ohms - 13watts , to simulate the MAP thermostat. Your thoughts?

      SLIPPING CLUTCH

      Morning Andrew I normally disconnect the Neg lead only, some folks disconnect both a few even say disconnect both and touch them together. Goes without saying both sensor plugs need to be checked and a squirt of contact cleaner applied never hurts 😅 Dave

      SLIPPING CLUTCH

      Hi Dave, I fitted one of the sensors on the rear but it has made no effect as the light is still there, I will fit the other sensor tomorrow and see how it goes then. You mention the disconnect the battery, is there any pattern to this ? is it both leads or just the negative lead? cheers Paneuro.
