Lost in Fabia Engine Bay

[jcarr162000]

Was doing a headlight restoration on my mums Fabia 1.4 Diesel Bohemia. Was using a small roll of modellers masking tape which I placed on the beauty cover of the engine while I worked. Unfortunately the roll if tape slid off and has nestled itself somewhere in undertray towards the front. Is there an easy way to get into this area? Dont really want to take the whole tray or bumper off, contemplated taking the fog light surround off and trying to get at it that way. Will it be ok down there for a few days, she never does more than 10-15 miles a day? Thanks in advance.

will be fine and may roll out somehow. undertray off is pretty easy if on axle stands. wheel ramps or a high kerb might be enough too. Think they are torx 25 ish screws
