I'm ready to blow up my W124066 320CE cabriolet. Had the typicle hunting idle as discussd on this forum, so removed the throttle body off my HFM injected 104. Checked the crancase beather hoes and decidec to change them while I had it apart. Well the litle nipple broke off the plastic manifold ( yes I cut it down the side as I did do my mechanics apprenticeship) si that meant off with the manifold. Repaired the nipple and refitted the manifold & cleaned/serviced the injectors as well. Reasembled everything but the bastard wont start. It wants to start, even catching a couple of cylinders, but wont. That stupid design manifold flap vacuumn pump is singing all the time, and I got a decoder from th States. Codes are as follows. Pin 8. code 25- CMP sensor not recognised/implausable. Code35- Model 124,129 & 140 air pump switchover vale &/or electromagnetic AIR pump clutch. (Australian models dont have n air pump so WTF) and code 49- voltage suply at engine implausable/low volts.
Now battery is fine, car cranks over fine, OVP fuse is fine and the car had a new engine harness in 2001. also I cannot clear the codes as per instruction manual of the decoder,which I might add is the same diagnosic system as was on my 199 740 turbo volvo, & I could work that fine.
Am I MISSING something here!
