Punto 2012+ 2013 Unplugged Green Punto Twinair

Introduction

So I've returned to the Fiat fold again after some brief encounters with French, Swedish and German cars.

I picked up a Punto Twinair just shy of 2 weeks ago mostly based on the colour alone.

Personally I absolutely love the colour and was the only reason I went to look at the car as I'd virtually chosen to disregard a Twinair car. After test driving though I really enjoyed the TA and so here we are.

I've covered just over 500 miles so far, the first tank about 60% motorway, 20% mixture of dual and single carriage way A roads and another 20% of town work. The onboard computer spat out 47mpg, after brimming the car again fuelly calculated 44mpg so not miles out.

Good bits;
  • Its similar to the Grande Punto, my first car, so things are quite familiar just with a refreshed look. Makes it easy to drive if un-envolving.
  • Noise. The thing most ordinary 4 banger superminis don't have is much of an exhaust note. The TA sounds great IMO.
  • Comfortable, did a 6 hour journey at the weekend, no numb bum at the end of it so a big plus.
  • Nobody seemed to buy the last gen of Punto so its suitably rare especially in this colour.

The Bad;
  • Twinair is weird to drive, I totally understand the people who don't like the engine. It can be too noisy especially in 1st and 2nd gears when road noise is low. You cant really drive it below 1500rpm and I like to keep it above 2000 to avoid labouring it.
  • This might be Punto specific rather than all TA's but the 6 speed box has very short gears, not the sort of thing you expect from an engine that creates its grunt in the middle of the rev range. You have to go up and down those gears a lot to maintain good progress.
  • Gearbox, following on from above its not got a positive engagment, I quite often find myself glancing down at the gearstick to check what gear I've selected. Reverse doesn't ever feel like its 'gone in'.
  • Bodyroll, I don't remember my Grande rolling this much but maybe its because I've had much stiffer cars since then. It leans and wobbles if you take a roundabout quickly. It doesn't feel like it'd understeer unless prodded harder but the bodyroll is comical.
  • It feels quite quick at lower speeds (sub 50mph) that its easy to forget on the motorway its not a fast car and in the outside lane it can get a bit out of breath.
  • Somehow Fiat have managed to design alloy wheels which look like hubcaps. At some point if a nicer set come up for a reasonable price I may look to change these.

TL;DR - I like it despite its foibles, which it certainly has plenty. The TA engine is fun but I understand people who dislike it.
In this case they don’t the whole undertray is one piece and it screws into the wheel arche liners, front bumper and back of subframe. With mine I also had to remove the wheel arch liner on the drivers side just to change the oil :rolleyes:
That sounds convenient...
At least yours likely has a metal dipstick with a crosshatched area for easy reading. Or did they only save that for the 1.2/1.4 petrols
 
Quick Update;

Over 1200 miles I've average 41mpg lots of that being stop/start town work. I think its pretty close to what my 1.4 8v did on my old GP.

Fitted an AUX lead that I adapted from the one I had in my Forfour (same plug just switched the bridged pins that make the HU know its plugged in).

Got oil + filter so will be doing an oil change very soon. Undertray doesn't have any flaps but it looks to be held on by 9 phillips screws so should be easy to drop.

Bought some clic-r pliers to take the airbox off, hilarious amount of noise insulation plastered to the bottom of it. Quite a strange design and makes changing the air filter a pain, 4 bolts to remove the box and then a further 6(?) to remove the filter cover.

Got the A/C recharged, its better but not outstanding although given we've had temperatures in the high 20's to low 30's I might let it off.
 
So I've run into the first signs of trouble.

Firstly I attempted my oil change (after buying a 24mm socket to undo the oil filter housing). Got the car jacked up and the undertray off with relative ease to find the sump plug to be in a ridiculous place and blocked by a bar thing...



Looking at it from the front above and from the back of the car below;



My deep 17mm socket isn't quite deep enough to reach past the bar and adding an extension is creating too much play to turn it as its been done up with a rattle gun no doubt. my breaker bar is waay too long to get in there given the weird position of the sump plug.
I will find a solution for this so no major worry but today after a few short trips in the car I started it and 'Stop/Start Unavailable' followed by 'Check Engine' popped up with the EML on.

Stop/Start error has appeared before, as I've mentioned its never worked but the check engine light is new. Car drove fine but the interior fan wouldn't come on. Stopped and restarted the car after a few miles and the same errors came up but interior fan working again.
Ran an ODB scan and got U3010 which my reader in unable to clear.

Any idea? I'm going to buy a ODB tool I can use with MES.
 
Undo the bolt on one end of the bar and pull it back and out of the way, see my grande oil change video where I had to do the same.

U error codes are usually related to the canbus network itself. They can also be specific to one car.

If you have MES or are getting it, this should give you more info.

Thanks for that, you're a star. I assumed the bar was under some sort of tension and if I unbolted it I wouldn't be able to get it back on again! :rolleyes:


The EML went out the day after it appeared, I think it may have just been something on CANBUS picking up the interior fan not turning that one time.

I got a compatible OBD reader but to connect to my ECU I need a registered version of MES which is a little pricey IMO. I'd happily pay for the software if it were half the price! :eek:
 
Oil change complete. The oil didn't look too old but definitely the wrong grade.



The useless dipstick is now even more useless, the new much more golden coloured oil is virtually indistinguishable so I put 3L in and just hoped for the best. Very alarmingly after priming the oil filter I started it up and it made an almighty clatter, switched it straight off and investigated. I forgot to swing the metal brace/arm back and bolt it on so it was rattling against the bottom of the exhaust :doh:
Now is running smooth again and sounds less clattery on a cold start. I will investigate the oil strainer thingy soon too.

Did my first fill up after 2 weeks of entirely start/stop traffic and only achieved 34mpg, I was entirely expecting these levels of economy having read up on it but I despise Fiat for selling this as a 61mpg car.

The car has been missing some underbody trim/cladding since I got it on the N/S. It runs from the back of the front wheel to the front of the rear wheel and covers the underside of the car up to the exhaust tunnel. Its like an undertray but for the entire car I guess, one on each side of the exhaust.

I can't seem to find a P/N for this and I'm not entirely sure what its called in order to search for one. Anyone got a more up to date eper?
 
Good job with oil change.. what tools did you need?

ePER ..
Fiatdalys have an excellent online shopping system.

My underside is NOT a smooth 'tray'

But a series of 'boxes'..

Makes me confused.. on the odd occasion I see the underside..

Oh .. and the Royal Enfield exhaust :p

Other than the 24mm deep socket I had to buy to get the oil filter housing off its fairly standard stuff. 17mm socket for the sump plug and a 16mm to take the bolt out of the bar that sits underneath the sump. In the TA guide on here they mention the difficulty of getting the filter housing out but the Punto has enough space behind the engine that this isn't a problem at all, just comes straight out. Getting the filter out of the housing however, found that to be a pain!

The forums version of ePER is dated 2005 and the Grande's didn't use the underbody plastics of the later Puntos. I think it is probably could be described as boxes but I think its all one piece nonetheless.

That website is very useful though! Found it P/N 51 899 571. €100 though, was hoping it'd be about half that, doesn't even including the fixings :eek: Can't seem to find it for sale anywhere else either :(
 
Have you changed the pollen: cabin filter

I changed mine yesterday.. 1st on a punto for me

I used Andys youtube guide :)

.. was a typical FIAT 5.5MM HEX HEAD screw retaining the cover.. so as expected.. :)

The 2 things that were odd:

Old filter was damp:wet at one edge.. weather hasnt been great.. but scuttle drains should be clear.. can it get damp through aircon..condensing..??

The filter was a denso brand.. pretty grubby

Wouldnt be too surprised if it was the factory original.. despite FSH.. at 3 different places :(

Thats why I am attempting my own servicing again .. Marelli filter this time :)

I have actually, I did that back when I got my A/C recharged as the fan blew a little weak.
The same 5.5mm hex was on mine, bit of a pain, had to dig through a drawer full of old tools to find one.
Mine wasn't wet although hadn't had any rain, it was a filthy shade of black and full of small bits of leaf.
 
The actual MPG matched the computer for once, 48.5mpg which is the best I've done over a tank so far, mostly motorway work.

On wet mornings its started squeaking for the first ~20 seconds, not a squeal just a quiet squeaking. Could be aux belt I haven't checked yet, seems odd for it to be going this early. In my experience they usually wear due to age rather than mileage and it's only 6 years old!
 
Well its still got all the oil in it and its still a nice goldeny colour although the sh** dipstick makes it impossible to tell.
I forgot to post here, just before I did the oil change I sanded a part of the dipstick to make it easier to read.



Planning on changing the plugs before the weather gets too cold as the service history doesn't specifically mention them being changed the invoices just say 'service'.

Anybody know what plugs they used from factory and the gapping? Thanks
 
Ask about plugs on modern panda section..

Mine is on its 4th set.. they have a hard life.. so I get them done early.

Memories of bad plugs killing coil packs.. and burning ECU terminals :( punto2

£20 Extra per year seems a good trade ;)

Had my 1st trip in a while last night..

Abingdon to Abertillery.. ( other Alphabet letters are available.. :p )
1.5 hrs of 70 along the M4

Trip shuffled briefly from 51.6 to 51.9 then back to 51.6

Im fine with that. :) supermarket basics all its 50k ;)


Mine does squeak at times..
strangely.. it was quiet today.. in the mist up a mountain..
but last nights run would have helped ;)

Scraped through the MOT needed front discs/pads imminently. They'll have to wait till payday. Annoyingly about 2-3 days after the MOT I heard an occasional scraping, had a look and the undertray was hanging down at the back. The MOT garage shouldn't have touched it as they aren't allowed to remove anything?
It's been attached without incident since my oil change, perhaps its just coincidence and it caught on something.
Its torn the two screws out at the back to will need replacing/repairing before I can refit (n)

Another interesting tidbit, whilst coasting toward a red light I knocked the car into neutral, braking gently and the start/stop cut in? It immediately restarted itself but was very strange whilst moving, I thought it was only ever supposed to activate with the handbrake on :confused:
 
Fitted an intake out of lockdown boredom. IMO it sounds great although ditching the air box which has tonnes of sound insulation under it has made the valvetrain noise more noticeable at slow speeds. Can’t get enough of the turbo flutter though!
I monitored intake temps on my OBD gauge before for about a week and after and it’s not raised at all honestly, I think the intercooler is more than enough for the engine.

However not all is well in Punto land. I’m still working every other day as an ‘essential worker’ but my commute has cut from a 30minute drive to just 10minutes which means on a chilly morning by the time I get to work the car has only been at operating temps for 2-3mins, this has been ongoing for the last 5 weeks. On Thursday leaving work it really struggled to start, I was turning it over but it just didn’t want to catch. After letting off the key to give the starter a chance to cool each time I’d get a start/stop unavailable message. On the 4th attempt it kind of coughed into life idling at about 700rpm with my foot fully on the throttle, eventually it brought itself up to speed and drove fine, I gave it a 20min blast up the motorways in 5th to keep the revs high.
Not sure what to blame the issue on, battery is the obvious but it cranks just as fast as usual. It started fine when I tried on Friday, usually only taking 1sec of turning the key to kick into life.
