CAXC 1.4 TFSI
The 1.4 TFSI from the EA111 family. Willing and economical, and defined by its timing chain. The tensioner is the known weak point and a skipped chain is an engine-out repair.

Engine and component issues
A loud rattle for a second or two on cold start; in the worst case the chain skips timing and the engine runs rough or is damaged. The early spring-loaded chain tensioner on the EA111 1.4 can lose tension when oil pressure drops after the car stands, letting the chain jump a tooth on the next cold start. Low oil level makes it worse.
Check: Start from stone cold and listen for a rattle; ask whether the updated tensioner has been fitted, and have the cam-crank correlation scanned.
Later parts: Updated tensioner design fitted from later production
Rough cold idle, slow throttle response, misfires, gradual loss of low-end response. Direct injection puts no fuel over the intake valves, so crankcase vapour deposits bake on undisturbed.
Check: Not visible without a borescope. Treat it as a service item that's due unless there's a receipt. It's not a fault, it's an unbudgeted maintenance cost.
Chassis, gearbox and body issues aren't listed here. They depend on which car the engine is fitted to. Open a variant page for the merged list.
