On this forum, there are quite a few people that are VERY knowledgable on the G37.
As our cars age, they will start to develop problems... and people will come here to ask questions and hope to get answers.

Here are some tips to increase your odds of getting a good answer to your request for help / question:
• State the year and model of your G37.
Things are different between 09 and 13, AWD vs RWD, auto vs manual, coupe vs sedan

• Use the enter/return key in the post to prevent the "wall of text".
If it is hard to read, many will just move on. I know I do.

• Describe the problem and when it happens.

• Scan for trouble codes, even if the check engine light isn't on, and post them.

• Be humble and polite.
No one here needs to help you... BUT many want to help you.
For example, if a specific task is requested, we might of missed that you have already done it.
Don't be rude and don't quote what you have already said. That isn't helpful to you getting help.

• Thank the person who is researching your problem and trying to help you.
This is how you keep on getting help.

In the end, you can ask anyway you want.
BUT if you want to increase the odds of getting help, make it easy for someone to help you.

 

Excellent advice. Thank you, Sonic.

 

100% agree with this.

When a member decides to inquire on something, they are asking for diagnosis's. These diag's require substantial information for the problem to be found in the right manner and at the proper diagnosable speed.
Being that we're an online group means we are 100% reliant on your information so it's imperative that this information is as informative and accurate as possible. If you have not bought a OBD scanner, this is your sign.

Example: in the electrical aspect of it, certain multiple P codes could mean a single bad ground that affects them all or missing power that is shared along the harness, so when this fails it affects multiple other systems making it seem like you have a plethora of problems however it could be a simple as a bad connection from a recent install that just happened. Many times problems in these cars usually happen after a physical change in the area ( intakes, exhaust, interior dissasembly, etc). The other times can be due to water leaks onto electrical controlling units.

Lastly this chassis was made for 8 years and it's 15 years old now. This is enough time for your typical problems to start affecting everyone regardless of mileage and use.
