Removing and installing particulate filter (LHD): VW Polo 6R 1.2 TDI (CFWA)

🧭 Before you start

Disconnect the steering universal joint, remove the engine cover, G505 connector, heat shield, lambda probe, temperature senders and turbocharger clamp. Remove the pendulum support, lower the subframe on pins and jack within the stated limits, remove the drive shaft heat shield and filter bracket, slide the front pipe clamping sleeve back and turn the filter out. Refit with new seals, self-locking nuts and clip, reinstall the subframe and align the exhaust free of stress.

Fits: VW Polo 6R (2009–2014)

• Timing position: the crankshaft or camshaft is set and locked during this job
• Renewed: with locking pins, seals, defective cable ties

Don't miss

• Lower the subframe no more than 10 cm on the right and 7 cm on the left.
• Secure the subframe with strap T00038 so the hydraulic lines are not stressed.
• Do not bend the front pipe flexible joint more than 10°; fit the transportation sleeve if reusing the filter.
• Renew seals, self-locking nuts and the filter clip.
• Align the exhaust free of stress after the subframe is back in.
