A couple of Nube questions

[Saff]

Hi, I'm sure there will be plenty of questions coming your way in the future

4.2 TDI, I'm assuming its chain and not belt for the valve timing?

Also, I try to do my own basic servicing so: I understand that the oil filter is on top and changeable from under the bonnet, as I always used a Pela suction pump through the dipstic tube on my E-Class (remove plug as no dipstick fitted) is there a removable plug on the dipstick tube 'stump' on the V8 TDI to enable me to do this?

Thanks for your advice, Steve
