Common problems to know about

01S tronic (DSG) mechatronic issues

Same dry-clutch 7-speed auto as the Golf on smaller engines, with the same known mechatronic failures. Jerky low-speed behaviour or hesitation is the tell.

021.4 TFSI coolant weeps

Water pump and thermostat housing leaks are the classic issue. Check coolant level and look for pink residue.

032.0 TDI emissions recall history

Many diesels went through the emissions-fix era; some owners reported subsequent EGR issues. Check what work was done and whether any related repairs followed.

04Timing chain rattle (early 1.4 CoD units)

Cold-start rattle on early cars means tensioner attention. Listen from a genuinely cold start.

05Infotainment and electric niggles

MMI screens, parking sensors and window regulators can fault. Everything is fixable — at Audi prices — so test it all.

MOT history: what to look for

Generally strong. Advisories cluster around front suspension bushes, brakes, and tyres. Check for uneven inner-edge tyre wear on S line cars with bigger wheels.
