Rebuilt engines offer peace of mind with replaced components, but they often cost more.

Can I drive with a used transmission without servicing it first?
It’s risky. Always service the DSG and inspect the clutch pack and fluid.

Where is the engine code located on the RS3 engine?
Usually stamped near the front engine mount area on the block — verify it before buying.
