I need oil level sensor for 750il BMW 1990

valve cover there should be a cap that says oil or have a speed lube change it and watch them to find out where it`s at.

contact the dealer with your registration there going to want to know your the owner first usualy you take the raidio out and there is a coad on it if thats not the coad the dealer can tell you the unlock coad from the radio coad lol

• The battery is under the rear seat. This is not to bad of a job but it seems like a ridiculous way to have to get at a battery. I'll direct you to a really great write up that has some pics for you as well http://www.cardomain.com/ride/433594/1997-bmw-7-series/page-15 .

• If you have any comments please feel free to leave them here.
• Hope this helps and thank you for using FixYa.

need alot more info

if you have to ask this question, you probably shoudnt be attempting to do whatever you are trying to do, you only get one shot at valve timing and serious damage to your engine and wallet can result from a mistake, seek out someone who can assist you.

Disconnect negative battery cable, disconnect wiring to altenator, then remove 3 bolts holding on altenator.
To reinstall you can move an idler pulley that will make putting the belt back on easier.

Hello
I do not know how your mechanic making that judgement , but most probably it could be repaired . You will know for sure after dismantelling the transmission and checking the interior parts of it.
Usually the vibration comes from the Transmission convertor and that happens if low on oil or oil pressure is law.
You will need to check the status of oil and filter before you do any thing as some times if the filter is in need of change , could do that too.

have your bmw dealers check switch it might need to be replace.

You have a cam or crank sensor that has gone out.

you may need to have a throttle body adaptation done at the dealership please rate -jeff
