1999 E300 TD. Yesterday , Mon. 6/1 on way home my Check Engine light came on Today on way back from work lost Turbo power. Yesterday I did ck my air filter and its dirty and will replace tomorrow. Missing both clips to air filter closest to engine. 1) would dirty air filter cause engine light to come on and lose Turbo power? 2) Not having a tight seal for air filter canister cause turbo to fail? Lost Turbo power did happen next day after pulling filter out of canister to check condition. Wonder what I did ?
