I am looking for ways to improve the life of the dual mass flywheel (DMF) in my 2005 Ford Focus tdci. I have heard that they can wear out quite quickly on the Ford Focus if they are driven in city conditions a lot, i.e. running on low revs and lots of stop-start driving.
Like a lot of people I spend 15 minutes sitting still in traffic most days, so I am trying to think of ways to improve my driving style to reduce the wear on the DMF.
I understand that at low revs a diesel engine puts a lot of strain on the DMF because it is running less smooth, however is there much wear on the DMF when you are sitting idle in neutral in traffic? Surely there wouldnt be much strain on the engine, so not much strain on the DMF also?
When you're running at low speeds in traffic and the revs are down around 1000rpm and the engine seems to be under strain and so could be straining the DMF, would it be better to drive faster at say 1500 rpm and then coast in neutral and then go back to 1500rpm when you're slowing down? Or to just stay driving consistently at 1000rpm?
I suppose it just goes to show that diesels aren't meant for city driving!
