Seafoam to clean manifold
2004 E320 4matic. 91000 KM.
Can I use seafoam to clean intake manifold without damaging or getting codes ? I want to hook it to vaccum line but am afraid that it may show codes or do some damage.

THE C350
I wouldn't use that stuff on any car... but if you are that worried you can take it off and clean it properly. My c320 had almost 215k when i sold it and still managed to get over 30mpg I think you should be fine with such low miles. Just keep up with normal maintenance (oil changes with proper fluids, air filters ect....) and do a Italian tune up ever few days 
I will say I did clean the TB at one point around 150k and yeah it was dirty but not honestly bad enough to cause any issues really.

New to Benz's myself, but seafoam is my go to for all my motorcycles I find dead and bring back to life. I have used it in the crankcase of my bikes to help release the clutch waste and other goo, since a lot of bikes are ridin until they quit.
