Removing and installing pressure differential sender G505 or pressure differential sender 2G524 — VW

🧭 Before you start

Remove the engine cover, intake hoses, rear insulation, particulate filters, catalytic converters and propshaft. Support the gearbox on the jack, unbolt the gearbox support and lower it the specified distance. Unplug and unbolt the sender, lubricate and pull its hoses straight off, and blow the hoses through toward the filter if clogged. Refit everything in reverse, including the gearbox support and propshaft.

Fits: VW Touareg II (7P, 2010–2018)

• Special tools named: V.A.G 1383

Don't miss

• Never remove the jack or leave the car unattended while the gearbox is lowered.
• Pull sender hoses off straight; the unions break off the sender very easily.
• Use silicone-free lubricant on the hoses, nothing else.
• Blow the hoses through toward the particulate filter to clear any blockage before refitting.
