hi.twin air 2012. very bad engine accelerate+ engine dash board light warning.
do you know this problem? what to do?
 
excuse me... but what is coil pack+where do I see the fault code? I didn't know what to do so I first put the car at the fiat garage, they too are searching for the problem,telling me it might be a problem in the wastegate(?) maybe it should be replaced...
 
Hi, the garage just told me, after checking, they found a crack in an air hose that deals with the air pressure in the turbo system(not sure myself if it is the exact term) and they will (costly) replace the hose and check if it helps. any advice?
 
Hi. Probably coil pack.

Read the engine fault code..and use that to aid buying the correct parts.

It this a turbo version?

Charlie

Surely coil pack would imply running on one cylinder only which render it pretty much undriveable? If it ticks over OK (no load) then I'd look for air leaks etc and hope its nothing to do with the uni-air module.

Good luck!

could you please explain:" imply running on one cylinder only which render it pretty much undriveable"
 
Sure, so you have a twin (two) cylinder engine which has a relatively small capacity 875cc or whatever and if turbo version produces a goodly amount of horsepower (85bhp others will correct my numbers if I'm wrong but it is not relevant).


The coil pack(s) - there are two, one for each cylinder, are used to generate the high voltage required to create a spark at the plug burning the fuel to generate the power or energy in the cylinders. If only one is working then the car, rather than accelerating would probably not want to run at all and would certainly run very poorly with half the power, in my experience you will have the engine warning light (yellow triangle) indicating a fault.


If there is a hole in the induction circuit hose or whatever this will likely affect performance but I don't have the experience to say whether there would be a warning light. This will likely give poor acceleration but the engine will probably run at tick over (no load, when not moving) ok.


The experience we have here is that any FIAT dealer diagnosis and repair is expensive and I'm sure Israel is the same or worse?
 
1.your numbers are correct
2.Fiat dealer is highly expensive-yes.(replacing the hose will cost more than 210 GBP)
3. what is:"the engine will probably run at tick over (no load, when not moving) ok"
4.shluld I ask them to check the coil pack?I told them (before they found the leak)
about the coil pack and they looked at me like I was talking nonsense...
thanks

Hi Yishir

First you should understand that I am not an expert, I can only speak from my experience and training as an Engineer.

1 Good but its not relevant to your problem
2 If that price includes the part, fitting and connection to the dianostic computer then this is good by our standards. For example my local dealer wanted 114GBP just to connect to the diagnostic computer when the car just needed a new battery (which was the same price)
3 I am saying that the engine starts ok and runs when standing still (tick over) it is running at aroud 800 revs - if this is happening then it suggests the coil packs are ok
4 From what you say I think you should go with their opinion, if one of the coil packs have failed then they would be able to diagnose it.

I had an experience where the Uni-air module failed (this controls the engine inlet valves) and it gave symptoms similar to yours but I REALLY hope this is not the problem with your car.

Most likely to be the cause in my view. If air leaks cause a fluctuation in boost pressure then this would likely flag all sorts of concerns to the ECU and the EML would come on. I'd bite the bullet and let the garage fix this cracked hose (ask to see the broken part afterwards, just to be sure) and I suspect it will be back to normal again.
 
I used to have a very highly-tuned Uno Turbo ie - Barry Waterhouse (remember him and his Fiat racing exploits?) did the job and reckoned it was the most powerful roadgoing Uno he'd come across. This used to perforate the high-pressure - and high specification - composite rubber/plastic hosse between the turbo and the inlet plenum chamber every six months. Apart from the loss of power, it also developed an extra, high-pitched whistle, which I came to recognise - it's too late for you to hear the way the noise has changed but, if this is the issue, you'll notice that the noise goes when the tube is replaced. The part was expensive but, with the Uno on ramps it was easy to change it.
 
the garage indeed replaced the rubber hose(f-500 0.9cc) attached with 2 metal bands.
I took a photo of the cracked one(can u see?). I hope it will work good.
there are very few panda TA here so they have little experience.
when the panda TA works good it drives(5 passenger) great .the question is:
when it will "fall" again ? and maybe I should have bought a regular 1.2 panda...

Well its good that it is fixed and I am impressed that your garage made such an accurate diagnosis seems you have some good technicians there! In my head a good, accurate diagnosis sweetens the bitter pill of the cost! Enjoy driving your revitalised Panda!

Either as R1NGA says a manufacturing flaw or the material has aged and someone has enthusiastically squeezed it when looking at the engine (as you might a radiator hose) and it has split, given the direction of the split I'd put my money on this. In Israel I suppose the operating environment (air temperature) is pretty severe and given the generally higher operating temperatures ageing would be my thought - how old is the car? Aged rubber (elastomer) does stiffen and therefore will not like to be strained by squeezing or similar (now this is my professional experience).

I wouldn't expect it to fail again in the short term, certainly other things will before this happens again but that is all part of car ownership! With the TA engine I would, however, encourage you to keep to the FIAT recommended oil change schedule and ensure the correct oil specification is used.

The TA engine is in my view a cool piece of engineering but with it you are producing 100HP per litre which in days past was the holy grail for many amateur racers and engine tuners so it is quite highly tuned and therefore sensitive, although I'm tempted to say fragile but I do not have this evidence, just treat it well!

What hose is that the top to bottom one. ??
