2015 Merc C-class 1.6 Petrol/Diesel?

Stallingrad

Pal is looking at one of these, anyone know anything about these engines? Seems small for a C-class, always thought a 2.0 diesel would be the best best. I see there is a 1.6D as well, is this the engine tweaked from Renault? Any ideas as to how it rates for refinement and reliability?

What miles do you do and where do you drive? If your doing tiny miles in built up areas petrol is the way to go.

Not specifically about the 1.6 Diesel engines but the other engines don't get great comments in these reviews below:

"The C200 Bluetec is even more efficient. The 134bhp 1.6-litre Renault-sourced diesel engine fitted to this model keeps CO2 emissions down to just 99g/km, and the standard six-speed manual 'box is light and easy to use. Performance is decidedly mediocre, though – you have to work the engine hard to get anywhere in a hurry.

The outgoing C-Class was one of the least refined cars in its class. Its diesel engines were noisy and coarse, and motorway journeys were accompanied by far too much wind noise. The good news is the new model is quieter than its predecessor. The bad news is that all the diesel engines still sound decidedly gruff, and there's far too much wind and road noise at a steady 70mph.

However, the optional Airmatic suspension – an £895 option on Sport and AMG Line versions – does a properly good job of keeping things comfortable on the motorway, where the C-Class lopes along in a manner that would shame some luxury limos. We'd definitely recommend it as an option.

Things are less impressive over sharp-edged bumps and potholes in urban environments, though, which all too often send violent jolts through the cabin. We've tried the C220 and C250 on standard suspension in the UK, and although it deals reasonably well with long crests and cambers, it rarely settles in town. On anything but a very smooth surface, the ride is bouncy, jostling those inside.

.....The C-Class’ upmarket atmosphere is spoiled when you twist the key and Mercedes’ ageing diesel rattles into life. The 2.1-litre engine fails to settle down on the move, either – it sounds strained when extended and drones on the motorway.

The optional £1,500 seven-speed auto gearbox is unresponsive to throttle inputs and often holds gears too long before shifting up. And while there are steering wheel paddles, there’s no option to lock the box in manual mode, so it frequently kicks down with no warning....

from my experience as a mechanic the diesel mercs are fairly bomb proof reliability wise

A proper car needs a proper engine. Avoid the weedy Renault unit and get the C220 at least. Or go petrol.
Even though the 220 has the older 2.1 it's a bit unrefined but well able to haul the car around at least.

But to be fair, you'd probably have no experience with the new Renault powered one, it's only out since last year. The one you'd be familiar with would be the 2.1, carried over, which as you say is decent, if a little less refined than the class best these days.
