2010 BMW 7 Series - Page 4 - Answered Questions & Fixed issues

loosen the OIL cap when the car is running,if the idle picks up and it starts to run better then the crank case valve on the back of the intake manifold is bad and needs to be replaced

if the temp guage is going high when engine is cold its the cable attached to the temp sensor touching the body at some point

if the engine is hot see if the radiator fan starts running if not see the cables that are attached to the fan and also see the thermostat

You have to provide the model of the car when you ask a question like this.

The first thing that you should check is the crankcase ventilation system. You have to be sure that all the tubing and the oil separator and its drain tube are clear and clean. On a 14 year-old car with ~200k miles on it? You are due to need to have that system cleaned out.
If that is not the problem, the prognosis is not good. The other likely problems are all expensive.

Did you put cheap gas in it recently or lower octane rated gas? Also, make sure your gas cap is on tightly.

If the cheap and easy answers aren't working, I would get a Peake code reader and see what the errors are (you may have a misfire). I wish I could give you more but this is a good start in determining what is going on, there are so many reasons why this is happening and by having the code reader you'll be able to isolate the problem better. The Peake reader gives you more specifics on the errors since it's specifically designed for BMWs.

Hop this helps!

Well sorry to tell you this but hes not the type of mechanic i would have working on my car BMW or any other car as all vacuum hoses are fitted on all engines for good fuel /even running etc
but the thing any mechanic would have is a vacuum piping chart as we all have them and some older cars only have 5 pipes but the later ones have up to 14 pipes so get the print out and do it yourself .

Ebay is a good source for owners manual. If it's service manual you're in search of check Amazon.com or BavAuto.com

check your fuses could also be a relay

please explain what you mean by valley pan ,now heard of a dog kennel and pigs tails and trunk for the boot and hood for the bonnet but this is a new one on me ,these bolts can come loose and drop out if they were loosened up for anything and not re-tightened properly but this could have been done before you bought the car ,older models with V belts can and do work loose on their own ,hence a proper service fleet vehicle style to ensure everything is correct and not a dealer style service where its profit motivated by changing everything in sight except a proper inspection

Hello Wade.

When the engine light comes on in any late model vehicle it has set a code in the computer due to a malfunction in the system.
The code will need to be read with the use of a scan tool or code reader.
Once the code is determined then it will need to be repaired depending on what it is.
Sometimes the code will lead to a direct repair, other times it is only a clue to the next step in the diagnosis.
When you are able to provide us with the code or codes we will be able to assist you further.

Thank you for using FixYa.

1. Remove bumper.
2. Pop off the grills. Easy to reach everything with the bumper off.
3. Take off the plastic fan cover.
4. Slide the latch cover off the bottom and reach up inside and pull the latch release.

i ahve one but i cannot upload a pdf document ,sorry

not suer what you mean here ,most vehicles have a slot on the back of the cam which lines up with the head ,check position of valves on no1 cylinder to make sure its correct though as some models use another mark

low coolant, air in cooling system, or it needs a good radiator flushing. have a good one !!

The battery is located in a compartment in the trunk

1. Check brake lights bulbs & replace if necessary. Also check the rear brake lamps ground connections.
2. If brake bulbs & ground connections are OK, remove the brake pedal switch connecting plug out from the switch socket. The brake pedal switch is placed above pedals on the brake pedal bracket.
3. Put a direct "hot wire" between two brake switch plug pins, and see if the brake lights work, ignition key in "ON" position.
4. If brake lights work, replace the brake pedal switch.
5. If brake lights don't work, check the brake pedal switch supply wire & fuse coming from ignition switch. If ignition key is in "ON" position the brake pedal switch supply wire, (plug pin), must have around 12 Volts.
6. If the brake pedal switch supply wire, (plug pin), is 12 Volts supplied, check the wire going from the brake pedal switch to the rear brake lamps for interruption & repair bad wire(s).
7. In the most cases the brake pedal switch is bad.
Good Luck!

This is not something the average "driveway mechanic" should even begin to attempt. BMW has made it a habit of using special fasteers that require special tools, as well as special tools to redo the timing after the head has been replaced. If you do not own a torque wrench and the $600 worth of special tools required to do the job, please do not attempt it. You will be getting yourself in much deeper than you anticipate.
