1996 A4 Sport 1.8t Engine (tappety) noise???

[150bhp]

Hi everyone, I've just returned from a 500 mile round trip in my old Audi A4 Sport 1.8t and the engines making a noise on tick over that i can only describe as tappety. Not to dissimilar to an old Ford engine(think mk4 Escort, mk3 Fiesta) if that makes sense? I've not yet had time to check the oil level but i do know the engines over due a service, could this cause the noise or anyone know what else i should check? Many thanks in advance for replies, cheers.

1.8Ts are known for turning their oil into sludge well before Audi say a service is due.

Change the oil as a first port of call and whip the sump off for a quick inspection if at all possible (usually lots of crappy congealed oil plugging up the sump and pump pickup).

Thanks Dr G, think i'll stick it in for a service and get them to inspect the sump while they're at it.
Was out in the car today and at first there was no noise. A mile later the engine was v noisy when left on tickover. Will report back when checked the oil.

Zero oil, oops! Hopefully no long term damage, filled it up and it sounds ok so far. Time for a service.
