Symptoms

Screen refuses to rise when the car is started
Screen goes blank or flickers
Grinding noise from the dashboard

Root Cause

The fragile ribbon cable connecting the screen to the base unit flexes every time it opens/closes. Eventually, it snaps. The plastic gears lifting it also wear out.

How To Fix

If it's a blank screen: replace the ribbon cable (kits available for £40, requires delicate dismantling of the screen unit).
If it won't rise: replace the motor/gear mechanism or the entire screen assembly.
Used screen assemblies cost £150-250. Dealer replacement is £800+.

Other Faults on This Variant

Water Pump / Coolant SIlca Bag Rupture

Critical

2013-201940,000–90,000 miles£800–£1500

The coolant expansion tank contains a 'Silica bag' designed to extend coolant life. This bag frequently bursts, sending silica gel through the engine and destroying the water pump and heater matrix.

Haldex Gen 5 Pump Failure (quattro models)

Severe

2013-201950,000–80,000 miles£400–£500

On quattro models, the Generation 5 Haldex unit frequently fails because VW/Audi removed the filter present on older generations.

DSG DQ250 Dual Mass Flywheel Wear

Moderate

2013-201980,000–140,000 miles£700–£1000

The 6-speed wet DSG gearbox (DQ250) is highly reliable, but the Dual Mass Flywheel (DMF) attached to it is a consumable item that fails predictably.
