Could be the exhaust making contact with the torsion beam. Mine did (although aftermarket), but someone had the same issue with a Monza exhaust when going over bumps.

Mines just on lumpy roads as well, i think now i've noticed it i keep hearing it. It's going for it's service at the end of the month so i'll get it checked out then.

My Konis are in the process of being whipped off and the original rears being re-installed as I type. They are then on their way to Koni who will then send out a new set. Just hoping the knocking noise disappears when the originals are back on!

Konis are off, originals are on and the knocking noise has.........gone!!
Faulty shocks are winging there way to Koni and a replacement set are on there way back to me.

The front Koni's. You have to be careful when doing them up or undoing them, the allen key part is very weak. I'm putting the rears back on in a week's time, if they get here!

It was def. Koni's, they sent them back, brand new pair!!. Mines a rag top, so can't be that screen thing, noise has gone, def. was shocks. I must say Koni are great, no problems changing them.

Full marks to Phillip at Alfa Shop.  He has arranged to have the shocks picked up via courier free of charge.  I also asked him about the Koni position on fitting costs and at the moment those of us with the gold ones are gonna have to sing for it.  Presume you will be fine with any dealer fitted and supplied black ones though.

Phillip did mention they were pushing Koni to at least cover part of the cost of fitting for returned items and thinks there will be more of a case for it in this situation as obviously there's been a c*ck up on their part somewhere.  To be honest, if there has been a problem batch of shocks it would be appalling customer service on the part of Koni to refuse point blank to cover at least part of the cost.

Good, I'm glad you've finally confirmed where the problem lay, and can look forward to getting replacements.
I agree with you wholeheartedly that Koni should offer some compensation for your costs incurred, and to this end, perhaps it would help if we could get a better idea of just how many Abarthisti supplied gold Konis have had to be replaced: a "mass protest" by a group of disgruntled customers is always likely to carry more weight than a number of complaints over an extended period of time from individuals.

It would be good to get an idea of how many of the gold variety have caused problems.  Phillip mentioned that Koni Holland said they had received two sets back (one black, one gold).  Phillip has another four sets on the way including mine (three of which are gold) but I've also noted that some people here have dealt with Koni UK directly so they will have a set of returns figures themselves.  So I would estimate there must be around 10 plus sets have been returned from members of this forum alone.  There are the ones that have been dealt with via Abarth dealers as well.  That suggests a serious problem to me that needs to be addressed.
