I've had a bl%%dy annoying tapping noise on my Estate for ages. It only happens when it's idling and it can be intermittent. The dealers have had it for four days without finding anything although all the mechs have heard it at one time or another. They have been looking around the dash area but I think it's coming from underneath the car and resonating around. I intend looking under there myself. I want to take off the plastic floor trays which line the underneath of the car. It looks like they're just held on by torx screws. Could anyone advise me whether this is a straight forward job and whether there is anything troublesome I should look out for? I would appreciate any advice. :yes:

On the 2.0 170 it is very simple to remove the undertray, I think that your vehicle should be the same, I have an inspection pit in my workshop so it is exteremly easy, just a few torx head screws. Not an easy job if you have to lie on your back with the car raised and suitably supported.

Thanks! My eldest said he'd come round in the week and put it up on axle stands. Do you know whether there's much under those plastic trays, particularly on the drivers side that could cause any sort of tapping noise?

Thought I'd stick up an update. I took my Superb into another dealer and they sorted the problem out within 3 hours. It was the fuel lines rattling under those floor panels under the drivers seat. Apparently there's some sort of bulletin on it. There's a new bracket and a shaped " sponge " to pad out the lines.My motor is now quiet as a mouse when idling! I am over the moon! :)
