This automotive maintenance tutorial was specifically written to assist owners of the 6th generation MK6 (2011, 2012, 2013 & 2014) Volkswagen Jetta sedan or Jetta SportWagen in cleaning or changing the engine air filter element for the 2.5 liter inline five cylinder engine.

Owners of other VW Group vehicles equipped with the 2.5L L5 engine such as the previous generation MK5 (2005-2010) Jetta, Vento, Bora, Passat, Rabbit, Beetle, Golf, Eurovan and Seat Toledo may also find these DIY instructions to be helpful.

A few compatible replacement filters including their part numbers are as follows: Wix 49186, Fram CA10085, Mahle LX2093, Mann-Filter C 43 102, ACDelco A3111C, Purolator A25596, K&N 33-2331, Pentius PAB10085, Mann C43102, Beck Arnley 042-1686, Premium Guard PA 5596, Hastings AF1324 and genuine OEM Volkswagen 07K-129-620.

The tools needed to access the engine filter include a pair of pliers, a Torx T20 screwdriver and a Phillips head screwdriver.

Loosen Torx T20 Screws
The engine air filter for the VW 2.5L I5 motor is located inside the plastic engine cover.

(This procedure might be similar for the 2015 and 2016 Jetta with the 1.8L turbo engine.)

The first step is to pinch together the two tabs on the metal hose clamp that holds the air intake hose to the inlet tube on the right side of the engine cover.

Slide the hose clamp away from yourself and towards the rear of the engine.

Then move to the front part of the air intake assembly and loosen the two Torx T-20 screws that hold the rectangular top cover in place.

Turn Over Engine Cover
Now you can pull the plastic engine cover off the top of the motor.

It is held in place by four rubber friction fasteners that attach to four plastic pegs on the top of the motor.

Turn over the engine cover and locate the 5 Phillips head screws.

Pull Out Old Filter

Inspect Both Sides

Flip over the air filter tray to access the old element.

Pull the old air filter out of the tray and inspect both sides of it.

If the old filter is relatively clean, just tap out the large debris and remove any dust with a vacuum.

If the old filter is dark grey or black and clogged with dirt, dust, insects, leaves, twigs and hair, it should be replaced with a new element.

I recommend buying the Mann-Filter C 43 102 engine air filter since it has excellent reviews on Amazon.

If you'd prefer to have the OEM filter, the part number is Volkswagen 07K-129-620.
