The 2014 facelift brought updated styling and improved engines. The worst timing chain issues were better understood and later cars had updated parts. This is the safest used 8X buy.
Early small-capacity TFSI engines (1.2 and 1.4 EA111) use hydraulic chain tensioners that lose tension overnight. On cold start, the chain rattles violently against the timing cover and can jump teeth, causing piston-to-valve contact.
The 7-speed dry-clutch transmission suffers from internal hydraulic pressure loss and electronic mechatronic module failure, causing severe low-speed judder, refusal to engage reverse, or total loss of drive.
The front and rear drainage hoses for the panoramic glass sunroof shrink and pull away from the A-pillar and C-pillar drain spigots, draining rainwater directly behind the dash into the front carpets.
The foam sealing gaskets on the rear light clusters degrade, allowing rainwater into the housing. This corrodes the multi-pin connector and burns out the common earth pin.
