okay I hooked up an OBDII reader to it... and it gave the code p0335 for the crankshaft positioning sensor... anyone know where to get that? and how hard it is to replace?

 

can anyone tell me where the CPS is located... and kind of how to swap it out for a new one... pictures would be grrrrreat... im going to change it tomorrow. thanks.

 

I was going to suggest cps,but you did not mention the code and if they start to go bad no code,if they fail code.

located at about the 1 oclock position looking from the front of the car on the top of the bellhousing area just behind the engine.Pop the hood up all the way with the hood button located on the hood hinge and use a good flashlight to see down there.

index the cps properly when you finish installing it.

 

we got it for seventy shipped to our house the bosch one as well from a local euro shop... ive read all the diy things.. but I still cant seem to find... I will try again right now.

 

I wish the check engine light would come on in my car...it won't...something is obviously teeing the computer off to the point where the engine acts goofy but will not trip the check engine.....that would be great....I swear the O2 sensor is shot but 90% of the time the car starts and runs great...it's the other 10% that leaves me with trepidation...and that's the most important 10%...plus I noticed in the rain today after driving the car that there was one of those little rainbow looking rings (as when petroleum mixes with water) right underneath the tail pipe...tells me engine running rich, unburned fuel coming out the exhaust...good luck on this issue

 

okay I found it once I got the engine cover off... I used to think you werent allowed to take it off... but now to find that torx socket... hopefully we have one laying around... there isnt any part stores around.

 

actually that sounds like a solenoid/starter issue...those Bosch starters are prone not retracting the arm...maybe...maybe not..just a thought...anyway...best of luck...cliff

 

you could always just jump the starter posts with a large screwdriver to see...it's pretty cool to anyway...but be careful

 

Don't ever jump the starter posts on a mb with das.The starting cycle needs to be generated by a rolling code supplied to the das system.You can royally screw up your ability to start the car.His code is cps,clear failure when it comes up,replace it and problem solved.
