ksing44, let the dealer do the head gasket and timing chain cover gasket replacements. Plan on doing the wiring harness replacement yourself ... from what I've read it's a relatively simple DIY job ... plug and play. Also, since you live in Downingtown get an estimate from Rex Carle (610-269-5050) for the gasket replacements. Rex is a local independent who works on BMW, Mercedes and Porsche automobiles. He's in the process of relocating his shop from Exton (610-363-7044) to 291 Norwood Road, Downingtown.
