I have a later style w124 fender on the wagon with a cold air intake vent. I would like to use it for that. Currently I just have a cannister filter sitting inside the fender, rather than the little plastic fitting with the round hole that seals on the inside of the fender and feeds the stock airbox. I guess I will try to buy the seal plate from mercedes.
I suspect that the na606 filter from the 1995 e300d is a bit under size for my fuel level on the turbo 606 motor however, so perhaps I need to fab something up and use the stock fender seal plate to feed a hose going to a larger box. Seems like maybe a 603 turbo filter would be bigger than a na606 filter. Is the 603 filter box larger than the na606 box? And where does the 603 box draw air from? The headlight? And is it wedged in behind the headlight like the na606 box?

On the 126 the EDS computer is located in the passenger kick compartment and requires no tools to remove. Not sure about the 201 and 124. 4 phillips screws in the lid removes the boards which are clipped together. Looking inside the 2 boards, you can see 2 heatsinks that are clamped to some transistors on one of the boards. You will want to remove the 2 phillips screws holding the OTHER board to the main heatsink/plug assembly. You can then lift it off and pivot backwards on the ribbon cable. There are plastic clips that hold the 2 cards together, they simply unsnap. Once you have the cards opened up like a book, the locations of the capacitors are obvious and the capacitors are clearly marked. On the board you didn't unscrew from the main heatsink/plug assembly, there are 4 capacitors: 100µF @ 50V Radial, 100µF @ 10V Axial, 22µF @ 40V Radial, 7µF @ 63V Radial. The board you unscrewed and pivoted out of the way has a single electrolytic capacitor 22µF @ 16V Axial. The circuit cards are double-sided, so be careful desoldering and resoldering. I used 63V parts for all my replacements. 7µF is also not a standard value, so I substituted a 6.8µF capacitor for it. Out of all of my capacitors, only the 22µF radial was good (I replaced it anyway). The next highest reading I got out of any of mine was .006µF In Germany, they'd refer to that as "kaput". ------------- Max Charleston SC _______________________________________ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com _______________________________________ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
