Replaced stock 2003 w220 rims with 19 inch w221 stock rims and tires. Rims and tires fit well but now I have an airmatic error ( visit workshop) on the dash.

Car had front struts replaced a couple of months ago with brand new Mercedes struts and block replacement and pump is a recent replacement as well

All was well before the rim/ tire switch.

I also had the front bumper replaced because of damage. Old bumper cover was removed and replaced with fresh new front oem
bumper cover.

Thanks for the help!

Maybe a ride height sensor arm wasnt reattached correctly. Check under te front wheelwells at the upper control arm and follow that link down to the sensor, see if its all good.

Good luck!
