Questions - Diesel engine and transmission / gearbox reliability circa 2014-2019 -BMW - Mercedes - Audi ( on small hatchback or coupe models)

I worked it out earlier for your 120d Vs a 220i. At 8k miles your diesel saved you just under £300 year which is hardly huge in the scheme of things.

However an EGR or DPF fault could easily eat that and more.
Also since you're seemingly insistent on a manual as well (as opposed to one of the main reasons for getting a "luxury" German car - a decent auto box), factor in a near certain DMF replacement with a clutch change.

Let's say an avg of 10k miles over a year which could go up. So probably around 400 a year?

EGR and DPF. I don't really have any faults on my current 120d for these as far as I can tell, and as I said earlier.i do hybrid city and motorway driving .

Am I correct in thinking the model which has the exhaust coming directly out horizontal doesn't have a DPF fitted. Exhausts that curves down do have one? Or is it the other way round.

My 120d e82 has a straight exhaust, not seen any dpf issues driving around



Clutch change, so this is another thing , I always thought that auto boxes were no less or more reliable than manual, cost more to repair when it goes wrong and doesn't have as good performance as manaul counterpart (delayed shifting etc)
