Question about Mercedes-Benz E-Class

1 Answer

My newly purchased Mercedes E320 1996 will not pass smog. Had it at dealer for 2 weeks, new computer, ran motor, etc. Previous owner had problem. Emissions are not the issue, seems it is a glitch in t

If cannot resolve, best case I can donate. Seems like a waste to junk for parts, as has so much life left in it. Bought car knowing it did not pass. Previous owner has amnesty from DMV, but DMV says has to pass for a title change. We only need it to pass for title change as our permanent home county requires no smog testing at all.

SOURCE: emissions test failure

hi what is meant by driving cycles are when you drive the car in all conditions accelerating stoping idling its a full range of what anormall driving run if you change a battery what you need to do is drive it in as many situations as metioned above so your ecu will learn what to do take it for a run between 50-60 mph for 30 secs take your foot of the acclerator see if it stalls if so do it again if after 3-4 times it doesn,t run correctly there is a problem with the sensors but usually sorts itself out i have done a job on a car in the afternoon and it takes till the following afternoon before it has relearned its setting be carefull while driving as the car can be unpredicitable stalling idling to fast ect but if it was ok before you changed the battery it will be ok yates210456

SOURCE: failed emmisions test..

I am in Virginia but I believe you vehicle is showing a monitors not ready for Catalyst & Evap. If that is correct you need to basically drive the car a few days. The computer will remonitor itself and should be fine following that. Most drive cycles require highway driving & city driving. Make sure you turn on a/c as well. Its not how many miles you drive but what conditions you drive that sets you monitors. You could locate the drive cycle and attempt to replicate it but its usually very difficult drive exactly as the cycle asks. Good luck.

SOURCE: weird computer glitch causing my car to fail smog tests

Once it runs all of the tests, its good to go. If you keep having that problem. someone is disconnecting the battery or resetting the computer or somehow the computer is losing memory. Have a shop check out why.

There should be a display. OE radios tend to use the car's general purpose computer display.
If there is a code It is likely to be an OE product and the code and audio manual (and spare keys) should have been passed on by the previous owner. If such things are not with the car the resale price should be considerably lower reflecting the trouble and expense not having such things can cause subsequent owners.

If the previous owner cannot or will not help I suggest you contact your local VW dealer.

Had both air fuel sensors replaced to pass CA smog. OBD2 evap and catalyst monitors say "inc" or "not ready," and vehicle won't pass smog.


Not sure how old the vehicle is, or model, or engine, so I can only give general suggestions. You may need new catyitic converters, or O2 sensors. They sometimes can't be corrected, just replaced.

Where is OBD 1 connector location for 1993 Nissan SE-V6 4x4 pick up?


Try disconnecting your battery for 2 minuets then reconnecting the battery . This probably will turn the light off.. then see how long it takes to come back on.. I had Mitsubishi that we never could find out what turned the light on.. The dealer even checked it and could not find the problem (did not even charge us) .. When we would turn off it would stay off for a couple of days.. so to smog it we would turn it off, smog it and worry about it in 2 years..Car ran great, always passed smog eaisly and got over 30mpg and went 200,000 miles..

Mercedes radio removal


Before removal if it is a factory unit a main franchised dealer should have the code, if not there are companies who recode them for a small fee. Cheaper than a new unit.

I purchased a car and the registered owner told me because the car was legally registered I would not need to smog the vehicle


Check all vacuum lines, egr and Pcv vlv and all the other junk that doesn't look like it belongs there. If you hear a hissing, it's a loose vacuum line.
Need to know why light is on but you could just disable it.

1996 Nissan Maxima GXE Fail Smog Check Due To ECM System Failure


There is no way to fix this issue according to my Nissan Dealer Service Manager. The monitors will not run and therefore the vehicle will not pass smog. If you need assistance from California's SMOG authority they are called "The Referee" and you can call them at 1-800-622-7733.
