This automotive maintenance tutorial was specifically written to assist owners of the first generation (2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016 and 2017) Volkswagen Tiguan SUV in checking or changing the engine spark plugs in the 2.0 liter TSI turbocharged inline four cylinder motor.

Owners of other VW or Audi vehicles such as the Jetta, Passat, CC, Atlas, Touareg, Golf, Beetle, A3, S3, RS 3, A4, S4, A5, A6, S6, A7, S7, RS 7, A8, Q3, Q5, TT and Q7 may also find these DIY instructions to be helpful.'

The OEM laser platinum spark plugs in this 2016 Tiguan were part number VW 06H905601A or 06H 905 601 A.

The OEM ignition coils part number is VW 07K905715F (also known as 07K 905 715 F).

The tools needed to complete this procedure include a plastic pry bar tool, a 5/8" spark plug socket, an extension bar, a 3/8" drive ratchet and a tube of dielectric grease.

The first two steps are to open the hood and gently pull off the plastic engine cover.

The plastic cover is held in place by four rubber friction fasteners on the underside of the panel attached to four metal pegs on the top of the engine.

Set the plastic engine cover aside in a safe place.

In order to remove any of the four ignition coils and access the old spark plugs, you will need to first remove the electrical connectors for all of the coils.

Use a plastic pry bar tool or a flathead screwdriver to firmly push the release buttons on the ignition coils down and back towards the rear of the engine bay.

You should hear the electrical connectors make a "click" sound when they have been released.

Spark Plug Socket
Carefully pull the ignition coil straight out of the spark plug well.

If your SUV has an engine error code (or DTC diagnostic trouble code) for a misfire, you may need to replace the ignition coil.

The OEM part number for the ignition coils is part number VW 07K905715F (also known as 07K 905 715 F).

Attach the 5/8" spark plug socket to the extension bar and a 3/8" drive ratchet.

Lift Out Old Ignition Coil
Lower the socket into the well and push it into place over the old spark plug.

Loosen the spark plug in the counterclockwise direction.

If you have trouble removing the old spark plug, try spraying in a small amount of penetrating oil such as PB Blaster, Liquid Wrench or WD40 into the spark plug well and wait five to ten minutes.

Once the old spark plug is loose, detach the 3/8" drive ratchet.

Spin out the spark plug the rest of the way by hand with your fingers on the extension bar.

Carefully lift the old spark plug straight out of the well.

Tighten Clockwise
Detach the old spark plug from the socket.

Inspect both sides of the old spark plug.

If the old plug is dark black or grey and covered in soot or oil, the engine might have an oil consumption problem and should be inspected by a professional mechanic.

If the old spark plug looks ashy white, the plug may have been exposed to high temperatures due to overheating.

The original (OEM) spark plugs in this 2016 Tiguan were part number VW 06H905601A or 06H 905 601 A (NGK M56P NG4).

A few other compatible replacement spark plugs with their part numbers are as follows: NGK PFR7S8EG, Autolite XP3923 Iridium and Champion KC8WYPB4 (9805).

Apply a very small amount of dielectric grease to the top of the old spark plug where it will come in contact with the ignition coil. The dielectric grease will help ensure a reliable electrical connection.

Push the new spark plug into the socket and carefully lower it into the well.

Spin in the new spark plug in the clockwise direction until it makes contact with the cylinder head.

Attach the 3/8" drive ratchet and tighten the new spark plug to just a fraction of a turn past hand tight. You should feel the new crush washer collapse as you are tightening it.

(If you are re-installing the old spark plugs after checking their condition, just barely tighten them past finger tight.)

Double check that the new spark plug is tight before moving on to the next steps.

Double check that the engine cover is securely attached.

Start the engine and listen closely for any strange sounds or odd noises that might indicate a problem such as a loose spark plug or a disconnected electrical connector.

Be sure to record the spark plug change in your SUV's service records.
