Thought of getting a Pre owned Tdci 2.0 since Euro 5 is widely available in KL. I would like some comments on the following...
1. Is the turbo diesel engine reliable?
Yes
2. Is the powershift dual clutch a dry or wet clutch? Does it give the same problems as in the Fiesta?
Wet, and its way more reliable than the dry
3. Is the cabin well insulated from road noise and from the diesel engine noise?
Not bad
4. Any common  problem areas  I need to be aware when choosing a Pre owned unit?
Make sure its well taken care off and hv good service history, parts are really expensive. Check wear n tear parts like mountings and bushings are still ok. Turbo hose is the common prob but can be solved by replacing with aluminium hose.
5. Since Euro 5 is available,  does the engine need to be re-tuned to enjoy the full benefits of euro 5 diesel?
Nope

Thanks

If these were fitted with diesel particulate filter, you're best avoiding them, with old euro 2 diesel , it may be end of life already due to the soot load inside the filter , dpf are very expensive to replace. If no dpf no worries.

Not that i aware off.

Take the trouble to go deep and look at te turbo, any signs of water or oil leaks , walk away , leaking seals always means a turbo rebuild

My gf sister owns the 2014 Focus titanium spec hatchback

Interior space I can say Myvi offers more legroom than the focus

The transmission not really that smooth however power is there when you rev it

This model is using dry clutch

Nvh and refinement not the best in class either

However a good buy if you don't have a large family and this can be served as a 2nd car if you have a mpv or suv at home
