I'm a new 147 owner and reading about bonnets flying open has kinda put me on edge about my new purchase!
My bonnet catch is horrible. It's covered in dirty grease and the safety catch? (the one you have to lift the lever up for to open the bonnet after pulling the release) is pretty seized, I assume there is supposed to be an element of spring action in it, which there is not currently, though it DOES seem to engage when slamming the bonnet down, i.e. you can pull up on the bonnet and it won't budge either in fully closed state or on safety catch only.
Went to nearest Alfa dealer they confirmed my car had the recall performed on it in 2004 (my car is a 2002 model). Tech there advised to WD40 it.
What's the best way? WD40 followed by Profi Dry, WD40 followed by 3in1 oil or a white spirit clean then Profi Dry? Or something else? Is the method described here
correct (i.e. WD40 only?) I don't care about £13 a can safety is what matters to me here.
We can all post tips and give our two peneth, personally I'd hate to advise then someone had cause to complain.
How I cleaned and renovated the catch on my car is not what I'm dictating as the only way or the right way.....just my way.
What ever you chose to lube the catch with IMO is not the issue, but how often you check or maintain it.
My only criticism of the ARDC file is advising to clean the catch in situ, the catch is only held in place by 3 nuts and is easily removed/replaced to give it a thorough clean....i.e a good soak in white spirit or similar, then removed any crud with a stiff brush......it ain't rocket science.
Again, what seems to be missed out is the cable pull, although some cables these day are coated, a little light oil won't go amiss as the catch spring can be overcome by a dry cable. If you look at the mechanism of the catch, you will see the 'latch' is only retained in a closed position very finely.
WD-40 is marvelous stuff but is only good for an instant or quick fix, and is a penetrative oil not a long term lube.
You need to decide whether or not to take advise from your local dealer, me personally.....I own 3 toys which are enthusiastically maintained on enthusiasts help and advise.......all from forums like this.
