Hi All
I've been getting a lack of acceleration going uphill intermittently. Looking through the threads I reckon it could be the dreaded ovalling of the actuator arm attachment for the wastegate.
It has thrown up a code for "turbo air leak" and if I move (what I think is) the actuator underneath the heat shield on top of the turbo it feels like waggling a stick in a bucket.
So I have a couple of Qs:
Does anyone know what make of turbo it is on a 2014 twinair 85hp 4x4?
And anyone know where I can get one from cheaply?
And if I put it in eco mode would this limit the boost and hence limit wastegate opening so prevent the issue until I get it fixed?
(I'm assuming it was only happening uphill because I was using full boost?)
Thanks all for any help
Jon

yes I've read a few posts about it but none of them really answer my questions (or at least the one's I have read). seems like there is a "kit" available but this is quite big money and I can't work out how to get one and it might be easier or cheaper to get a new turbo (especially if I'm paying a mechanic to do it).
It might be that I haven't found the right post so if you know of one please send me the link
Much obliged
Jon

Hi Jon :)

Member Goudrons may recall the finer details.. but around a year ago somebody had drilled out the ovalled slot..and fitted a bush to restore the original tolerances

They did the repair with the bonnet up ;)

The turbo is a Mitsubishi TD02V.
I think one of the Fiat part number is 55243430, though there does seem to be more than one number, thanks Fiat!

The clevis on the actuator arm does seem to wear and go oval and I think someone had the same problem a while back.
https://www.fiatforum.com/panda-iii/487060-turbo-actuator-availability.html

I seem to think the wastegate spindle can wear and this causes the clevis to wear as well, so it's worth checking the spindle in the turbo carefully.

There are new complete actuators available with the clevis.
Nerings sell them on Ebay, they are from Lativa.

There are after market clevis, though finding one that's the right length, thread, hole size might be a bit hit and miss.

If you can get yours off, a turbo specialist might have one that fits, or take the old one to a local engineers, see if they can bush it or fabricate a new one.

brilliant thanks goudrons. I've seen some on ebay so if the spindle on the turbo is OK I might go this route.
