timing

Not posted for a while, since I’ve had around 25-30k trouble-free miles (apart from self-inflicted odometer jam last Summer, which was an easy fix). Nearing 180k now. BUT... A few weeks ago I had my local garage fit a new cat, an after-market one (recommended). Since then I’ve had both cold...

I've recently bought a 2013 Mercedes A180 Diesel and I wanna know if it has a timing belt or Chain? And which oil would it take for the engine? Thanks!
