#2532 of 2589 tapping noise by jkobty2 Apr 26, 2009 (8:04 pm)
I have the 2009 mazda6 2.5 I4. I am noticing a tapping noise when accelerating from a stop at low rpm, as the car shifts, the noise is gone, so only appears at initial acceleration. It does not happen when idling. And I only hear it in the evening probably because of much less outside road noise at night compare to driving during the day. I tried reproducing when at idle, I can hear it if I rev up slightly to 1000 rpm. if I increase the rpm, the tapping sound is gone. Is this normal of this engine, or should I be worried and take it in for service? I did notice on my oil change receipt from the dealer that they are using bulk 5w30 oil. The manual recommends 5w20 oil. Could the thicker 5w30 oil be causing this issue? Replies to this message: lg2207 (May 15, 2009 7:35 am) jkobty2 (May 30, 2009 9:41 pm)
#2533 of 2589 different problems by racegirl4 May 01, 2009 (5:47 pm)
Well I'm blowing a lot of smoke on start up. I'm wondering if maybe it's a bad PCV valve? Also, I have a CD jammed or something. I put one in and now it's not working. It won't even switch CD's. Is there anyone out there that can help me out? Give me some info or something? I'd really appreciate it!
#2534 of 2589 2004 Mazda6 2.3L crankshaft and balancing shaft timing marks by epicmetal May 15, 2009 (7:05 am)
I have a 2004 Mazda6 with the 2.3L motor. Assembling the motor installing the crankshaft and balancing shafts but know one knows the positioning of the crankshaft to the balancing shafts. And I mean no one, not the dealership the engine machine shop or the local repear shops. Hopefully here I can get the information that I'm looking for. If anyone can help let me know. Thanks   John

Replying to: jkobty2 (Apr 26, 2009 8:04 pm) Sounds familiar- I had that on my '07 6S (check my posts and replies)-- turned out to be a bad design by Mazda of the Idle Air Purge Valve (poor placement and materials near the firewall)- same thing- in the 900-1200 rpm acceleration phase- and very slight noise----- wonder if they carried that design over........ Did you get anywhere with it? Replies to this message: jkobty2 (May 30, 2009 9:41 pm)
#2536 of 2589 2009 6i Bluetooth Issue by vfontjr May 21, 2009 (8:53 pm)
I took my car into the dealer today to have them fix the bluetooth. For the second time since I bought the car last October, the bluetooth cut off and wouldn't turn back on. (The bluetooth menu option is grayed out and remains inaccessible.)   The first time this happened, it came back on by itself after 3 days. This time it went out about two weeks ago and never came back on. The dealer admitted that they didn't know what the problem was and had to call Mazda Tech Support for assistance.   The fix was to disconnect the battery for 10 minutes and reset the electronics. They said the bluetooth is sometimes left in limbo and performing a reset by removing the power is the only way to get it back. This is just my opinion, but it sounds to me like their software has a memory leak somewhere and rebooting the electronics has the same effect as rebooting a computer. It works now.

#2538 of 2589 Something Weird is Happening by vfontjr May 27, 2009 (10:58 am)
Today the Auto button for the front windows on my 2009 6I stopped working. Thwy'll go up and down as long as you hold the buttons, but the press and release feature ceased functioning. Weird! Replies to this message: vfontjr (Jun 23, 2009 1:47 pm)

Replying to: ianmatic (May 23, 2009 7:15 am) my niece has complained about the same issue. I have not experienced it because I usually wait for the rpm to go down before driving off. all cars idle at high rpm initially when the car is cold.
#2540 of 2589 Re: tapping noise [lg2207] by jkobty2 May 30, 2009 (9:41 pm)
Replying to: lg2207 (May 15, 2009 7:35 am) I checked the earlier TSB and confirmed from the drawing that the car has the new design. So I do not think this is it, I also confirmed with another mazda6 with the same 2.5l engine, and it has the same noises. Sounds like a sloppy job of enlarging the 2.3L.
#2541 of 2589 oil change by sedmund Jun 07, 2009 (4:11 pm)
According to the 2009 mazda6 manual the oil change per "Schedule 1" is every 7500 miles. Does anyone here in this forum follow this, or do you do the usual every 3000 miles? Replies to this message: jeffyscott (Jun 08, 2009 5:03 am) sedmund (Jun 14, 2009 7:19 am)
