Can anyone tell me if an Audi a3 is lying up 10 months would the engine be seized??? It's on a slant so would the oil be stuck in a bad position?
It may or may not be seized, but putting a spanner on it and rotating the engine is one way to find out.
Before that I would suggest to check that there are no birds nests in the belts, that you have put fresh fuel through the system and have a properly charged battery - you might find it starts fine unless it wasn’t running when it was left.
Once you have it running you need to check the tires and brakes.
You will find a couple of answers that also make good points here: Could a car left sitting for 6 years ever run again?
