Hi all,

Recently bought a second hand I30 FD. I've noticed there is a rasping noise from the front of the car when accelerating, which seems to be loudest in 2nd and 3rd gear around 20-30mph.

It stops immediately when I take my foot off the accelerator, so I'm certain it's not wheel bearings. It sounds more like an exhaust blowing but the car had an MOT a few weeks ago with no issues identified.

I have noticed the exhaust manifold heat shield has some play in it - all the fixing bolts are tight  however there is a metal netting around each fixing hole and the whole shield can easily be moved a few mm.

I wanted to ask if these were supposed to be fixed firm, as if so this may be the source of the noise.

Thank you, @BrendanP, that will be very much appreciated. I have read that there should be absolutely no play laterally (up/down or side to side) but in and out of the joint shoukld have movement. I've also read that a worn inner CV causes vibration/wobbling whilst a worn outer CV causes clicking sounds. Which is what has directed men to a possibly worn inner joint.

I've had the wheels balanced, which didn't change anything, but haven't had tracking checked yet. Suspension bushes and linkages all seem OK.

Hi there, MarkAndyJ

to the forum.

y mechanic is crazy busy, so he hasn't been able to look as yet. He mentioned that a friend (UK Hyundai mechanic) said badges can start to 'peel' and cause the radar to play up.

Hmmmmmm - funny you say this. My PD's front badge, behind which the front radar module sits has something of a 'cobweb' like cracking to it. Its made of plastic/acrylic and has a few minor stone chips in it.  I wonder if this is the issue?

If so it's absolutely beyond pathetic - that Hyundai hasn't recalled all vehicles as what a preposterous situation - ABS, ESC, cruise control, etc all shut down due to a cheaparse branding badge thats cracked due to crappy materials.  I sincerely hope it's something a tad more worthy as I'd be infurated if so.

When I get a chance I'll try and wiggle the shaft on my car. I'm not sure if that would contribute to the car wobbling about as I don't think the driveshaft acts to anchor the wheel in position, I think it can move in and out to accommodate the suspension travel and steering movement. Have you checked things like the track rods ends and ball-joints for slack movement? Also whether the tracking is correct.
