Technical Euro6 1.2 Throttle Response, Hill Start Issues & Watchdog report

This brings us back to the question of why the problem apparently affects some Eu6 cars but not others. If that were true then surely Fiat could correct the problem by finding out what difference there is between them?
 
Mmm, good point. Did the Euro 5 have the clutch "voodoo" treatment, do you know?

No.

IMO understanding exactly how the new type clutch position sensor works could be the key to understanding this issue. One idea I have is that, due to manufacturing tolerances, there is some variation between individual cars in the output of this sensor in relation to the actual clutch position. If this is the case, it could explain why some cars are seriously affected, some less so, and some apparently not at all.

It also raises the question as to whether the proper functioning of the Euro6 engine might be compromised as the clutch wears in service.

There is a general lesson to be learned here, I think, which applies to pretty much anything of significance you might be considering buying:

Do not assume that the latest version of anything will be better than, or even as good as, the version it replaced.

Oh, I cherish our Gloworm boiler. 40+ years old with 3 moving parts (flame, water, pump). Solid as a rock, though not the most economical.
 
Please don't forget that this issue isn't a Euro6 problem.
The problem only affects Euro6 1.2's ............. but not all of them.

Clutches?
Maybe.

Right. As per my previous update, I was requested by Fiat to go up to Chippenham, drop off the car at the dealership, pick up a loan car (which I was very lucky to have according to Fiat), and then wait for the fix in April. Oh, and the initial hire period was 2 days which took me to Saturday morning.

Fiat sent a message to Enterprise stating that they were cancelling my loan car after the initial 2 day period and that I would be liable for the daily costs thereafter (@ £22.00 per day). Needless to say, I took the car straight back to Enterprise because nobody in Fiat had the courtesy to return ANY of the 12 phone calls made to them on the Monday chasing for them to extend the hire period.

So I am now using a friend's car until such times as we know more....it maybe a long wait...watch this space.

You're right in saying it's only 1.2 engines that appear to suffer from this issue - but I'd say there's little doubt that this has all come about because Fiat needed to gain Euro6 homologation for this engine.

They wouldn't have messed with a proven design just for the fun of it.

Fiat are really taking the p1ss now.
 
Yes I am sure this is the cause as its only when the clutch is at biting point that the revs go erratic,which is a real nuisance when in traffic and must be hammering the clutch.

Yes, they wouldn't have messed around with a proven engine, but why only SOME of these cars?

We still haven't found the key to this.
Some Euro6 cars are affected, and some Euro6 cars appear not to be affected.

We can't blame the engine.

Whatt? Fiat have to give you a loan car!? Tell them to give you one immediately and keep on calling them!!


22 gbp for a corsa? That's embarrassing for that money I hire a bmw 1 series :)
 
Lol I thought you'd enjoy my update everyone!

Yes - it's farcical. And for them to be SO insistent that I get a loan car (which they never do for their customers apparently) and for them to then suddenly take it away from me after two days just highlights some of the games they're playing.

And it appears their phones have stopped working to make outgoing calls, too....wonder if that's a similar fault to the hill starts?

by the way fiat greece told me that they only provide loan cars under warranty, so i dont get a loan car. i called them because i was angry my spare parts were taking a month to get to greece!
 
I think people on here with the problem need to start bombarding Fiat hq ,and see if it makes a difference just a suggestion ,keep copies send recorded delivery ....

It may well affect all cars as having driven a 1.2 Euro6 engined 500, I could easily imagine that many owners would not actually notice the issue until faced with a decent hill start and even then probably think it was just a cold engine or some brief glitch. But then, admittedly that could have just been the car I drove.

As much as I'd love to have someone talk me through the software algorithms it all does make you long for those days of a carburettor, a clutch and a couple of cables.

Has it been established how many cars have the fault?

Can't see it. We'd hired a brand new 500 last month in Spain - I was braced for the problem as it's hilly, proper hilly. It as fine.


Also, does it just affect UK cars? We get non-UK visitors to this forum, but is there an equivalent problem on LHD cars? Do the LHD cars have cable clutches like the Mk3 LHD Panda?


Hard to believe it's still a problem all these months later. Staggering.

I think a physical protest outside would suffice I'm in London March 20 Friday anyone joining ?

What you really needed is for Top Gear to have taken up the issue and mockingly laid our 30 or so 500s on a long hill.


That's not going to happen now of course, though, silver lining, hopefully the Moxford idiot will not be back.
