Have Mercedes Questions? Ask a Mechanic for Answers ASAP
Hi, you need to only swap one item at a time to determine if it's the sensor or the solenoid. I'd just replace them all as Mercedes is having a lot of trouble with them. If your codes come back you probably have a balance shaft gear going bad.
Please remember to click Accept for my help today. I notice that you never accepted on your last question where I gave you the instructions for the belt.
can you send me a print out of the location of the sensors and selenoids
I thought you just moved them side to side?
yes i did but when i spoke to the dealer they had no clue of what selanoids i was referring too i kept saying the ones under the cam sensors
The dealer calls them camshaft magnets.
ok thankyou now i know
what normally goes bad more often the cam sensors or the camshaft magnets?
Both go bad but the magnets are more common.
so when i go i just ask for two cam shaft magnets does it matter if i say bank 1 or 2 or are they all the same part number
Correct, they are all the same
now what happens if it is determined that its the magnets along with the sensors that are bad can i still drive with them bad
Yes you can but I would not recommend it. If the problem is actually the balance shaft gear failing you can cause severe engine damage.
ok thanks, XXXXX XXXXX to take my chances and replace the magnets first because they are less expensive
do you recommend to get the magnets after market or the dealer
so if my scanner reads bank 2 is it necessary to change all 4 magnets
No, just do the bank 2 magnets and see what happens.
ok thanks you were great !
