Yeah. The part came in yesterday (new drivers side door switch panel). It was the central locking button that was at fault. Fitted in 30 seconds. Reset my windows. Jobs a good one. Thanks for the replies.

I unplugged the driver side window/lock button cluster and the problem went away. PM'd Alex to see if he has the part. Thanks for the help.

Hi all, Bit of a weird problem in my 09 370Z. It started about a week ago when I heard the car continually trying to lock itself outside my bedroom window. No lights were flashing, but I could hear it was trying to lock itself as if the internal "lock button" rocker switch on the door was being pressed. The car unlocks with both fobs and keyless entry buttons (including boot keyless unlock) just fine, but it'll randomly try and lock itself again. Car starts and drives just fine (albeit continually locking itself driving down the road). No warning lights on dash, no "door ajar" warnings. I haven't scanned for codes. Has anybody seen this before? What sort of things should I check? Now that I write this, could it be the driver side door "lock" rocker switch at fault? It is something I use everytime I get into the car. Hmmmm. Any advice welcome, Alan.

My stage 2 clutch and Solid flywheel combo arrived today. Thanks Ewen. I've bought a few things from Clark Motorsport over the years. Always a pleasure to deal with. Will definitely buy from them again.

How did you manage the On/Off button? I know you can get programs that put it into a deep sleep when the charger is disconnected (engine off), and wake up when the charger comes on (engine on). But what about those times when the battery runs down and the device shuts down completely?

Just had the hub done. Noise is gone. Case closed. I am once again, a happy Zed owner.

I immediately though wheel bearings. Is it coming from one side of the car? Get in! i can also do a full MOT by kicking the tyre. Yeah, the maddening thing is that I thought it was coming from the drivers side. Even when sitting in the passenger side with teh mech driving. I was holding out for bearings myself as well. It's a simple fix. We'll see if this fixes the problem.

The diagnosis is the front passenger side wheel bearing is shot. Diagnosis process: Went out for a test drive with the mech who at first couldn't hear the noise. I could hear it quite clearly, but I guess I was attuned to it. Anyway, we tipped into a roundabout and I told him to push it a little going in. This re-produced the noise at a level audible anough for the mech. He went back and checked the wheels again. Tyres were fine, but on full lock (to the right), he gave the passenger side wheel a shake and found the bearing was done. It was nice and tight in the straight ahead position (which is what I tested). So, the moral of the story is: When checking your bearings, try it while a mate holds the wheel at full lock as well. I'm getting the hub assy replaced next Friday. Hopefully this will solve the problem.

Thanks lads. It's going to be Friday before I get the time to look at it. I'm driving my diesel workhorse to work just in case it is a tyre issue. I'll keep you posted. Thanks again for the suggestions.

Really? How would this happen? I do indulge in the odd session of spirited driving. But nothing too serious. Damn, and they're expensive tyres (here anyway) as well. €165 a corner.

Cheers mate. I'll post back here when I get to the bottom of it.

Definitely has that quality to it. Or a buckled rim perhaps????

Definitely not a belt problem. I replaced the Alternator belt a few months ago as well. Besides the rhythm quickens with road speed. If it was a belt, I would have expected it to match engine speed. Now that's a point. This I did not check! Cheers, I'll check that out.

No. I'm running Hankook Ventus V12s. Defo not run flats.

I want to say the drivers side .... but I think that's just because I'm sitting on that side. I can sort of feel the whump whum throught the steering wheel as well. Very faint though.

Hi lads and lassies, Lately my 2004 Zed has been exhibiting a "whump whump whump" sound when driving along. It sounds very much like the classic flat tyre sound. Or like a car driving over the segment gaps of a long bridge. A rhythmic "whump" that increases in speed with road speed. The sound was originally only prevalent when taking corners, but lately it happens in a straight line as well ... and seems to get worse when the car gets warm. The sound doesn't go away when braking, so I'm pretty sure it's not brake related. The tyres are in good nick. All 4 brake discs were replaced in the last 4 months (with new pads of course). I've tried the classic wheel shake test to test the bearings and all seems tight. Spinning the wheels by hand don't seem to produce any weird sound either ... but I'm not ruling out bearings. Does any of this sound familiar to anybody? I'm probably going to bring the car in to Nissan in the next few days because I can't diagnose this sufficiently. But I thought maybe some of you good people might have an idea what it is, or maybe able to suggest some more tests I could perform to diagnose the problem. Thanks for reading, Al.

Thanks everyone. I dug out a pic of my Z with my other indulgence:

Biker you say .... I happen to be quite partial to taking my GSX-R 600 out for a blast on occasion.

Where did you get these discs from? Are they for Brembo brakes? I keep seeing discs for the 350Z at one price, and then the Brembo versions at a substantially higher price.

There's one or two Welcome to the forum - tidy looking zed you got there Damn my clumsy typing. But you know what I meant ...

No, they were on it already. I did notice them when I was looking at other Zs though.

You should see it now. Dirty slush hanging off it. Covered in (frozen) road dirt. When we get over this cold spell, I'll give it a good wash.

Here are some pics:

Hi Lads and Lasses, I've been lurking here for a few weeks. I treated myself to a 2004 350Z (with the GT pack) about 2 months ago. So far, I'm loving it. Not so much in the snow/ice, but when I do get a dry patch .... I just ordered a nurrish SatNav system last night. So I thought I'd better introduce myself properly. I live in the midlands of Ireland. Are there any other 350Z owners on here at all? I've been servicing my own cars for a few years now, and I intend to do the same with my 350Z. Already did an oil&filter change. It needs new brake discs soon, so that's next on my list. Probably change the brake fluid as well. This is why I think forums (with DIY/HowTo sections) like this one are invaluable. Thanks, Alan.
