Thank you for the good news! It appeared that it would be accessible via the method you've outlined. Although with the mild winter we've been having here I'll be able to do this at my leisure and I will simply bypass it for the immediate future.
As for you advice regarding the manuals I concur. I have not been able to find or purchase anything except the engine manual in print so far as these manuals are no longer in print nor available from MBUSA. I have obtained a collection of manuals on CD but a rather lengthily search has been fruitless for me so far.
If you by chance can recall which manual this information is in or the numerical job code for the procedure I would appreciate any info, then I could then go straight to the appropriate PDF file on my CD. If you can recall how the white plastic clips holding this part are released that would be very interesting also! Thanks again.
