Removing and installing oil filter housing: VW Polo 6C (AYH, BAC, BAR, BGH, …)

🧭 Before you start

Clear the intake side (air filter housing, bracket, cover, air intake and air duct with EGR pipe) and remove the dipstick tube. Drain the coolant, take off the wheel housing liner, the electric coolant pump, noise insulation and poly V-belt, and hang the compressor out of the way with lines attached. Disconnect the N428 valve and other connectors, remove the thermostat housing and lower the oil filter housing out. Refit with new seals, bracket bolts evenly to 15 Nm, oil filter to 20 Nm and harness bracket to 10 Nm, then refill coolant.

Fits: VW Polo 6C (2014–2017)

• Opens: coolant
• Renewed: seals

Don't miss

• Seal the dipstick tube hole in the sump with plugs once the tube is out, or coolant can get into the oil.
• Leave refrigerant lines connected; unbolt the compressor and tie it up on the right side.
• Renew all seals and O-rings and use production-standard hose clips.
• Tighten oil filter bracket bolts evenly to 15 Nm and the oil filter to 20 Nm.
• Keep a cloth under the thermostat housing to catch oil when it is pulled off.
