New 595, Rear arch buzzing/electrical noise
« on: October 31, 2020, 05:17:52 pm »
Hi There,

Firstly this is my first post, this week I picked up my new Abarth 595 Competition which is my first ever Abarth car. I have had the car for three days now and love(d) it - however, on day three of ownership something really strange has happened. I have spoke to the dealer, however the UK looks like its about to go back into lockdown so I am in a situation with a brand new car, potentially I cannot go back to the garage until covid lock down eases and I don't know if I can use the car.

Basically at the back of the car, drivers rear - when you get to 30mph a buzzing sound starts, as you increase speed it gets louder and louder - by 70mph it sounds like a pair of hair clippers working double time. It is not faint, it is very loud. I have tried to jet wash the rear acrch and wheels, checked the tyres as I wasn't sure if it was coming from there and no change. It does have the beats audio system installed, sitting in the back with my wife driving it does sound like it is coming from the speaker - however I don't understand how increasing speed inscreses the sound. It is also static, happens all the time now - just buzzing whirring, and when I decrease speed the buzzing decreses also.

Does anybody else have any ideas what might be causing this or any experience of the same thing? Just very odd on a brand new car with less than 100 miles on it.

Thanks in advance - any information big or small would be really appreciated! I would like to be able to drive the car, but I am also worried incase something bigger is amiss.

Cheers!

    If the noise is consistent with engine revs even whilst stationary then possibly electrical interference due to a missing suppressor on rear of alternator body, used to be common with cars from 1980's.
    Only other likely cause I can think of would be the in-tank fuel pump being noisy as its roughly situated where youre hearing the noise from, though you should hear this better underneath the car Id think.

    Hope this helps.

    Thanks for the reply, I tested stationary and it doesn't make the noise - only whend driving. It is consistent with increasing pitch with speed. It is going back to the dealer this week so maybe know more soon.

    So the whole issue has been referred to Abarth now in Italy, the dealer replaced the wheel bearings as they were shot - within three days the problem came back, back in the garage and the new replaced wheel bearings are also broken. They do not know what would cause them to break on a car with only 200 miles on it straight from the factory.

    Wow...I would be insisting a new complete rear axle, didnt expect that to be the cause  :thumbd:

    Well, your reply couldn't be more ironic! I just had a call from the dealer who has spoken to Abarth - they have been told replace the rear axel. Then I saw your response lol so you were spot on the money there. They have said this has never happened before and it is a completely new issue for a factory build car straight off the back of a low loader.

    I can only hope this fixes it, must be the root cause to trash two sets of wheel bearings witin 200 miles on the road.
