Spark plug OEM BMW or OEM Volkswagen

If you’re buying a used VW. This is the easiest one (Polo) to maintain.

1. Figure their parts change and maintenance schedules and follow. Check oil cap for oil type to use (15-20k is fine).

2. Always check oil hoses, rubber seals and gaskets (40-70k).

3. Change engine bushings (100k), chassis bushings (50k), transmission bushings (100k) for first time used buyer.

4. Check condition of all parts above before change, also include spark plugs. Stick to German OEM plugs (50k).

use BMW OEM plugs from the dealer. Yes the are expensive but I have never had a problem with misfires and I've put over 100,000 miles on my current E36 and over 150,000 on my first. While they are suppose to work and be interchangeable according to the manufacturer the NKG you buy aftermarket are supposedly different than what you get from BMW

I replaced the spark plugs, ignition coil plugs, alternator and checked the tensioner.

FWIW, I just had spark plugs and coil packs done on my 2016 Jetta, $185 out the door at my local dealership

I had a 2012 Passat I drove for 10 years (after buying used with ~20K miles) and only just replaced two weeks ago with ~125k miles. I had to replace the alternator at one point and some other general stuff like spark plugs over the years, but that was it really. Nothing super expensive.

I had similar problems with mine until I tried stock F80 M3 plugs. Mfg #12120039634KT1. Mine was 07 N54 FBO.

Guy was gunna charge me $720 USD for changing my serp belt and another $550 USD for changing just my spark plugs. That's $20 for the serpantine/drive belt, $150 for the belt tensioner and I think another like $120ish for spark plugs (B58 engine). So in total I saved myself roughly $1,000 just doing it myself.

I’ve done an oil change as well as swapping the spark plugs and coils for brand new ones. The roughness persists!

I just came across a recent problem while doing my spark plugs at 80,000 miles. The dealership was the one that did my spark plugs at 40,000 miles. Sure enough, they broke Cylinder 3\u2019s wiring harness connector to the coil pack and stripped the bolt. I had to helicoil the bolt, replace the connector, and repin the connector.
