Scissa's 2015 Polo 1.2 TSI
Posted: Sat Dec 27, 2025 10:23 pm
Hello everyone, in the recent months i was using this forum very frequently now i wanted to share my experiences and adventures throughout the ownership of the car. I am scissa and i live in Turkey. I am a mechanical engineer and had experiences in automobile industry at production plants.
The car is 14/5/2015 Comfortline equipped with CJZC EA211 1.2 TSI 90hp with PED 5sp. manual transmission. It has been purchased from the first owner at 8/2018, Currently it is at 103600 km's and it is increasing.
Recently, i have changed the spark plugs with a different one from the catalog and parts list. I used NGK 94224 IKER7A8EGS Iridium, which is service part for EA211 evo, or 1.5 TSI and 1.0 TSI models.
The stats were looking the same except the material and reach of the spark plugs. The EA211 1.2 and 1.4 TSI engines do originally use NGK 95463 PKER7A8EGS Platinum plugs.
I believe Iridium plugs are better compared to Platinum ones.
Since there was nothing to lose, I wanted to give it a shot. The specs of the plugs are:
Platinum Plugs
Iridium Plugs
When the plugs were original, the car was not misfiring on VCDS but i was definitely feeling them randomly at idle. I guess they were below the threshold to register as misfire.
When the plugs were changed first, the idle was horrible and the engine was about to leave the engine compartment
After few start and stop cycles, the result turned out to be absolutely amazing. Now the car is not sluggish anymore at any condition, it can pull from stand still like a rocket, or no need to downshift when climbing a hill with very low RPM such as 1300. Also, it consumes less fuel now.
I couldn't find any sources on the internet for this upgrade (except https://world.taobao.com/lang/en-us/goo ... 080876.htm), so i decided to create a guide for it for everyone who searches it.
For the oil change, the car had numerous oil brands through the ownership. The best ones for this engine are Motul and LiquiMoly. As you know, the engine has a very annoying cold start rattle/knock. These oils just prevent that noise completely.
I will share the mods that i applied or will apply like footwell lighting, glovebox lighting, second trunk light, cloth wrapping the plastics, windscreen wiper fluid sensor installation, sound insulation, dismantling the car, vcds coding, adding heated seats, problem solving, rcd radio upgrade with car menu
, and many more for this platform.
