M157 V8TT | Spark Plug Replacement Poll**
Hello fellow forums members,
Just wanted to take a head count of all the forum members who have been experiencing spark plug issues.
All M157 owners please chime in. If you haven't replaced your plugs still post a reply so we can paint a better picture as of why this issue is recurring for some of us.
1. none performance package, performance package, or tuned
2. at what mileage and under what condition did you changed the plugs if at all
3. how many times you've changed them
4. total mileage on vehicle
5. driving style
6. fuel type you're using

No spark plugs replacement for me. Checked with the dealer when I took my car for other minor issues. They checked my VIN and ran my car through the STAR diagnostic and no error came up.
My car is 2012 CLS63 with 6700 miles (it has the older Navigation system) and it has the PP package. Took my car to the track a few times. No mods.

never had a problem when i had manufactor plugs ( even when tuned )
after dealer replaced my plugs ( major service ), one broke while WOT, new plugs had less than 6000km on them.
i am thinking propably the plugs that they installed were old stock and have some quality issue.
1. performance package and tuned
2. 30k km, major service as dealer says in GCC.
3. once
4. 39k km
5. the worst in history, LOL lots of > 300km for more than 10 min, daily WOTs
6. 93US, 98 UAE.

As people mod the TT cars the added boost subjects the spark plugs to added stresses.
Look to the EVO and Subaru tuners to see what type of spark plugs they use when the boost gets turned up...

Did you retune it to stock before you took it to the dealer?
