As I said in my post, I recommend the tight reach wrench (
link is here) - it made it much easier to get to some of the bolts on the duct clamps.
Also, you might remember the electrical connector (for EGR temp sensor) that I said I had trouble disconnecting? Good to know I'm not alone. Check out posts #60 and 61 on
this link - it's for a 335d, but the much of the info is relevant to our 35d. FWIW, I went back and tried the suggestion in post 61 of pulling the white tab all the way out, but I still couldn't get it to work. For me, using a very small flat blade screwdriver slid under the connector from the back side is still the best way to get it apart.
BTW, if you're replacing the thermostat I assume your temp is also not getting above 72-73 degrees?
Regards.
