Re: Several problems with my Punto!

Could be a bad earth or connection somewhere. Remove and clean any and all earth straps battery to chassis, chassis to engine / gearbox and so on. Then heavier looking wires especially those towards the steering rack. When 12v motors pull current you get all sorts of voltage dips unless connections are good and a dodgy connection might still check good using a multimeter. Open and clean them!

Hey, thanks for the advice!

Spend 2 hours to find all earths and cleaning them. Unfortunately no such luck the PAS problem is still there. However, the power loss seems to have been reduced significantly, just a small hold back near 3000 RPM but I can live with that, as it's hardly noticable.

PAS light still burns, but keeps working nonetheless. Only happens on almost full lock, I can steer a little left and right when stationary, nothing happens. But when backing out a parking lot or such, there it is again.
Could it possibly be a sensor or something?

Re: Several problems with my Punto!

Hello!
Been a while and have been trying to sort out the problems still. Only to have found more, of course.

PAS light is still on, but steering assistance keeps working nonetheless, so really a non-issue.
However, I have two ELM327 bluetooth dongles and have connected them both. However when my phone connects the boardcomputer completely resets, as if you've detached the battery. Anybody have any idea?

Another small issue is that when I've been driving for a while the clutch goes a little ' lumpy' when changing gear (when I put the clutch back up) which makes for a very rough gear change. I've read that this could be the slave clutch cylinder?

Would like to hear your advises, thank you

Re: Several problems with my Punto!

I had this issue on both my puntos. On the Sporting it turned out to be the power steering motor (first of all the light comes on periodically, then it'll start to fail and the steering will go heavy).

I managed to get a cheap replacement which fixed it and didn't cost much from the scrap yard.. really easy to replace too.

My HGT took a little more work. On that it turned out the be the whole steering column that needed replacing... Luckily there is a firm in Birmingham that sell them refurbed for 150 (on the condition that you send back your faulty one within two weeks). For this you get a refurbed motor, steering column and ECU... they are nice and shiny too!

I got a friend to fit it for me as it was a more involved job (he did it for 60 although a garage will charge more) and i've done about 25k since without an issue.

Re: Several problems with my Punto!

Thanks mate, will go on the look for a replacement motor in my area.
Hopefully it won't give out before I get a new one though, haha.

Any ideas on the ELM problem btw?

Re: Several problems with my Punto!

Hi,
Rather than using a phone, get a laptop and download MultiECUscan, www.multiecuscan.net
This should work with a bluetooth ELM 327 (if laptop has bluetooth). Make sure you can connect to the engine etc and then pay the registration fee so you can connect to the power steering module. This will give information on the fault(s).
Most 'phone software is not powerful enough of Fiat specific.

Robert G8RPI.

Yes.

Worked for me.
I could read the free engine module but it would not read the power steering or airbag.
