I need to R&R the Exhaust Manifold & related components on my 1994 e320 wagon to clean out the egr tube. I have the CDs and Booklands w124 Owners Workshop Manual. Unfortunately, they don't provide enough information for me regarding this R&R.

With the help of the dealer's workshop manual, I've R&Red most everything on 88 Ford 2.9L v6 [Merkur Scorpio], but the Benz system is much more complex. Are there any other more detailed sources available for this Benz engine. My wagon has been sitting for a month now because it won't pass emmissions and I can't afford the $1,000 the shops want to do it.

Thanks
Bob

PS Also need to R&R Engine Temp Sensor. Where's it located?
