Ticking noise from the alternator

<< < (2/3) > >>

The only way to know if it free wheels is to take the slack off the belt or remove it and then check the wheel itself.

The filings would usually come from internals.

Mine would not free wheel.

I had a nightmare getting the pulley off snapped two torx bits, had to take the alternator out and do it on the bench.  :sick:

In the end i used the impact wrench flicked it clockwise then anticlockwise a few times and it came off.

I have the correct tool for this job but the alternator needs to be out to  impact it off as I did an audi A3 one last year and there's no way it was coming off any other way  :wink:

As above impact required to save yourself swearing too much... I've replaced the pulley at 80k but just recently at 150k bought a second hand alternator from ebay with a pulley on, only £20 and works fine, at that price just do it. :happy2:

I think your right, I don't have any error codes on the dash - however after changing the alternator would I need to plug in a VAG to reset any error codes? (I don't have a VAG system)
