23 Tiguan L replacement spark plug

September 3, 2024

It was just 6 months since I picked up the car and had a mileage of 20,000 kilometers. I was going to go to 4S for maintenance. Before going there, I bought a set of spark plugs at a discount on the Double 12 and replaced them.
The 330 flagship engine model is DPL.

Although it is easy to replace the spark plug, it is the first time the Tiguan L has been removed and is unfamiliar with it, so it takes a slow step by step.

The main tools are special sleeves for spark plugs, torque wrenches and long sleeves, because to disassemble and disassemble the stud bolts, the sleeves need to be lengthened.

I wanted to remove the ignition coil plug first, but after the buckle was pried, the plug would not move at all and could not be opened, so I had to remove the stud bolts that fixed the ground wire and the ignition coil.
Remove nuts, ground wire, and bolts

The feel of this stud bolt is strange because it is not tightened smoothly.

A hook is prepared to open the wiring harness buckle. The previous car is relatively old, and it is easy to crush the buckle if you pinch it hard.
The new car is really good. If you squeeze it with your hand, you can hear the crisp sound of the buckle opening.

The plug is very tight, so it is slowly shaken before opening it one by one and pulling out the ignition coil.
