2005 Acura RL 40K miles. Dealer states I

Many cars set this lamp as a result of reaching a certain number of miles that clock in on the odometer. It usually means you've reached a particular service interval - often a "major" one.. Other times, it can be the result of detecting a malfunctioning sub-system or sensor that needs attention. Your mechanic (possible autoparts store) can usually scan the computer to determine exactly what the cause is.

Did you ever find a solution to the P0304 warning. I am at 40,000 miles on my 07 RL and got the same warning along with an AWD warning. Just got it serviced last week, what a coincidence.

you should have it flushed only at 40k miles.some dealers will say every 30k miles....but it should not be changed until 125k miles....the fluid is very expensive...35 dollars a quart...but up to this point just flush the fluid which will clean it for reuse...

IT is a "Time for Service Code" B2 Means its time for an oil change, Tire rotation, Cabin filter replacement and air filter replacements. Call your dealer or local Acura rep for an appointment. Hope this helps.

05 Acura RL reset Address Book, Calendar, and Go Home gray out.

Close the door, use remote and press both lock and unlock at the same time until you see red light on the remote blink. Then release and press unlock. It will fix the problem. I call Tustin Acura dealer and got the answered.

You need to do the trans fluid and power steering every 30,000 miles on all vehicles. Forget what they say
I used to own a trans shop.
Flush Brake fluid every two years
Coolant every three
Spark Plugs at 60,000 miles
Fuel Filter 30,000 miles.

I would stay far away from the dealer
Go to a local shop

Your best bet is the dealer, It may be a recall or a technical service bulletin. Dealer or electronic specialist.

it is in the radio, you have to take the radio out and get a serial number and call the dealer!

there is no major trick other than removing front and rear flange bolts and center support bracket bolt and $2200 is very high dealer in delaware it sells for $1450 for part

change the oil and filter is not done, replace the air and fuel filter if not done, service the transmission if not done.
