My check engine light was on so i checked it last week to see whats wrong and they told me code p1397 comes on after is cleared cam shaft position sensor is bad needs replaced. if Anyone had this problem its a challenge shifting on the first gear u killing the engine . Anyone familiar with the cam shaft sensor how much will it cost me to get it replaced
google "bmw camshaft intake sensor" and a butt-load of wholesale retailers will pop-up. mine went bad last month. i bought it for $95 online. took me about 30 minutes to replace (you'll need the Bentley repair manual for your car... solid investment). you'll require allen wrenches, flat head screwdrivers, star wrenches and one pair of alligator pliars to remove the VANOS solenoid unit (i used the pliars from my trunk kit, perfect fit). don't forget to have some string or flexible wire handy... the sensor has an 8" length of wire that passes just above the alternator through some tight spaces... tied-off spare wire makes threading it back easier.
Thanx guys, like i said on the first gear u have to go at least 3000 rpm and it only does it when the car runs hot , im going to replaced next week to see if it gonna make any difference i heard a lot of people had the same problem and after they replaced car runs like new
yeah you have only one cam sensor it's the M54 which has a sensor on the exhaust side.
and not that it makes a diffrence to this topis but you actually have a M52TU which the TU stands for Technical Upgrade which mean you have a throttle by wire and no actual cable.
spot on, the 2000 year 3 series have two camshaft sensors. i had to replace my intake when it failed, my exhaust was fine. as a side note, the exhaust looks like it's a whole lot easier to replace than the intake. none-the-less, a quick fix.
I changed the sensors yesterday check engine light is gone , i had to change both sensors first i changed the intake and it didnt make any difference when i changed the exhaust one its was worth it the money i spent
