350David Posted October 31, 2015 Posted October 31, 2015 Hi guys, This is a weird one. Just had my 2007 350Z Roadster serviced and MOT'd at Nissan and, because it had just broken down before it was booked in, over £2k repairs on cooling fans, bushes and screen washer switch. Now, I've driven it twice since getting it back. Second time last night on a short motorway trip and as soon as I get to 65-70mph I get this flapping noise that appears to be coming from the front/bottom of the car and it literally disappears when I drop speed again. I'll be taking it back to Nissan obviously but wondered if anyone had a clue what it could be so I don't get ripped off. Thanks all. Dave Quote
glrnet Posted October 31, 2015 Posted October 31, 2015 Plastic undertray/wheellarch liner not secured properly. Be careful I know of one or two on here who lost the wheelarch liner at speed because it wasn't secured correctly. Bloody stealerships!! :bang: Quote
davey_83 Posted October 31, 2015 Posted October 31, 2015 engine undertray loose........................ have you had a look underneath as yet? Quote
KyleR Posted October 31, 2015 Posted October 31, 2015 Had this also when I had a garage fit a new metal Z Speed under tray. They appeared to had cut the rear of it for some reason, maybe the bolt were seized or something, and that small section was flapping about at exactly 70mph. Quote
350David Posted October 31, 2015 Author Posted October 31, 2015 Thanks everyone for your replies. I've had a look under the bonnet and the car and found what I think is the problem. Got a manager at Nissan calling me back on Monday. Livid. Took a photo but unable to post it. Looks like a long thin flap under the engine at the front/middle with a hook/ring thing on the end that has clearly come loose or was never tightened at all. Unbelievable. Quote
jimboy2 Posted October 31, 2015 Posted October 31, 2015 It's nissan, it's very believable. Just don't take it to them again and get a decent specialist to do your work next time round. There are plenty of good ones on the forum. Where abouts are you based? Quote
350David Posted November 1, 2015 Author Posted November 1, 2015 Hi Jimboy, yea I'm learning. Interested to see what the manager has to say for himself tomorrow. Definitely using a specialist next time. I'm in Surrey at the moment. Quote
ZMANALEX Posted November 1, 2015 Posted November 1, 2015 . I'll be taking it back to Nissan obviously but wondered if anyone had a clue what it could be so I don't get ripped off. Thanks all. Dave Unfortunately, it sounds like you already have. Stay away from the Nissan franchise dealers, unless you know them first hand or by recommendation that they know there way around 350/370/R35.

BobbyZ Posted November 1, 2015 Posted November 1, 2015 Abbey Motorsport in Oxted are highly recommended Quote
350David Posted November 1, 2015 Author Posted November 1, 2015 It's been an expensive lesson alright Zmanalex. Thanks for recommendation BobbyZ. I'll give them a shout next time anything goes wrong. Hoping it won't be for a while after the morons at Nissan fix their botch job. Quote
jimboy2 Posted November 1, 2015 Posted November 1, 2015 Yeah abbey or Horsham developments (no where near Horsham) you won't go far wrong with them. Quote
Jack wellZ Posted November 2, 2015 Posted November 2, 2015 I also have this weird plastic wobble type sound when I'm hitting around 60mph, can hear it quite loudly when turning left. I've checked the arch liners they seem pretty sturdy, it's also not the undertray as I've just changed that to a torqen tray and is as tight to the body as it can go. Any other suggestions? Thanks Quote
350David Posted November 4, 2015 Author Posted November 4, 2015 Jack I'm sorry but I don't know what that could be. Mine was definitely the undertray. Nissan took it back in and have secured it but today I got a call from their service manager telling me that, despite their "full health check" not picking it up, not even a mention of it on my MOT and after a full service, my middle and rear section of exhaust needs replacing for £500 just for parts . Apparently they noticed it today while the car was on a ramp getting the under tray (that they left hanging out of the bottom of the car in the first place) secured. This is Nissan!! I'm in there tomorrow morning to have it out with them. If I wasn't so furious I'd laugh. Quote
jimboy2 Posted November 4, 2015 Posted November 4, 2015 Do you have a OEM exhaust still? Ask for pictures. If it is actually worn you can buy a full stainless system for a bit more than the rubbish OEM one. Don't let them do any more work on it! Quote
350David Posted November 4, 2015 Author Posted November 4, 2015 Thanks Jimboy. I won't be letting Nissan touch it don't worry! Quote
