    Evening all
    As title says i have got a slight problem with a ticking noise it is really loud i first thougt it was coming from inside the car untill i went outside had a look and it is coming from my fuel rail and not my charcoal canister which i know ticks. The ar struggles to start since this ticking noise has come earlier today.

    Has anyone ever experienced this and could give me an idea what is wrong or what to do i will give it a scan on vagcom in the morning to seenif anything comes up

    Thanks grant

    I would unclip the Fuel pressure regulator on the fuel rail, and make sure its not blocked by disintegrating fuel line first..
    Bill had a pic showing one blocked once..

    The clicking sound you can hear is your tb trying to reset.
    its because your wiring to the tb on the side is loose, unclipped or corroded.
    i had this problem and drove me insane.
    if you take your inlet pipe off you will see the butterfly going nuts.

    the problem is your wiring.
    yes you can take the hose off your tb(the one from the intercooler) to check to see if the butterfly is the clicking noise

    If the butterfly is clicking try moving the connector on the tb to try and stop it clicking

    Right ...
    Got the rac out to have a look he first said its flooded as he thought he could smell alot of fuel. He then managed to start it with a jump pack after giving the starter motor a beating.

    He plugged it in to his laptop and the ect sensor come up as a fault so i will change that tomorrow but could the ect make the car not start and also every time the ticking noise comes the fuel pump primes can it cause so many problems.
    Thanks grant
