Hello, I am have quite a problem on my 1994-E-420 Mercedes. I was having a problem with the check engine light coming on about every three day's and the code was #26. I checked all of the vacuum lines and all were ok. I purchased a new upshift delay vacuum switch, which I was told the culprit was that, now the problem is since I changed the upshift valve the check engine light now comes on every day, I reset it and the next day it comes on again still code #26 I just threw $34.00 in the garbage, glad that I changed it and not the dealer?? Does anyone out there have any super ideas to repair the problem<IMG src=smileys/smiley17.gif border="0">I sure can use all the help <IMG src=smileys/smiley14.gif border="0">that anyone can give me. Thanks everyone. Ben Still wondering if anyone on the forum has any ideas as to my problem.<edited><editID>bigben3</editID><editDate>38021.7452199074</editDate></edited>

 

My check engine light came on last night on my 1999 E 320 because the car ran out of gas. How do you reset your Check Engine light...just wondering so I can try to reset mine myself.</P>

disconnect hot battery cable,then reconnect. that will reset the check engine light</P>

 

It will reset on its own after several starts. Don't disconnect the battery unless you have your radio codes handy.....

 

Thanks for your responses. Actually, the 'check engine' code did disappear by itself after 2 days.</P>


Thanks</P>
