I've done thorough research and it appears the problems arise with modern diesel cars when you only do short (less than 10 mins) journeys everyday. It takes about 5 mins to get warm enough and a further 5-10 mins for the active regen to take place and complete.

So if you're doing at least one weekly journey of at least 15+ minutes, you'll be fine as the car will start the active regen process under even stop and start city conditions by pumping extra fuel to get exhaust hot enough.

But if you're only doing short journeys of just 5-10 mins everyday, then you'll have serious problems.....

Also, better quality fuel also helps. I.e. avoiding the supermarket cheap stuff....

However...there may be a lot of other issues with having a diesel car for city driving. Best to buy a petrol car for city driving!!
