General Diesel Judder??

[Plon71]

Car back from Corts today, without judder. (So Far). They've done a full service on it and also replaced the Turbo Boost sensor, or MAP sensor as the mechanic also called it. I gave it a reasonable blast up and down the M66 and all seems well at the moment. Will keep you all updated if this turns out not to be the problem. Apparently this sensor was caked in carbon dust, so rather than clean it, they've swapped it.

Hi all,

Car has been back in for the last 3 weeks, still got the judder, still being looked into what the cause is, hopefully I'll have an update l8r this week.

Hi Plon71.
Mine got sorted under warranty. I had the gearbox and dual mass flywheel replaced.

Oh God, just read this thread... I've got it, the judder, deffo. Tends to be after 20-30 mins, including spirited drive - i'm not a town commuter. Darn it. Todays judder was so bad I thought I was going to breakdown (but didn't, it subsided).

(also worked late tonight and walked out of the office to a flat... brilliant, not much Bravo love today)

Hi All.

Just got my Bravo back, it was dropped off whilst I was away, so i'm still trying to find out what exactly has been done. It's looking like they've replaced all the engine valves etc etc etc.

They've had the car for 5 weeks, and Fiat technical have been invloved, when I get the full report, I'll update my post. All seems ok at the moment.

My car has been at Richard Cort Fiat, Manchester Road, Bury. BL9. I can't fault the service from them, so if people are having the same problem, it might be an idea to contact them there. I dealt with Alan and Leanne.

Cheers, Paul

I've got a 10 month old, 10K miles, 165 Mjet Sport and get the same symptoms. Problems started at about 6 months. First it was changing up to 6th on the motorway at about 75 - 80, judder and no acceleration, and increased fuel consumption. Gradually, this progressed to intermitently occurring on upshifts at any speed, but usually around 2000rpm. I do a lot of town driving with a bit of motorway in between. Average fuel consumption is now down to 34mpg - absolute rubbish!

It's been into local Arnold Clarke three times, had an exhaust "regen" whatever that is, and then the EGR replaced under warranty. Also had replace engine oil warning appear. AC tell me it needs a software update (is FIAT and acronym for Microsoft???) but they haven't got the kit to do it at either of their two local branches. For God's sake, these guys are supposed to be professionals.

 

[Plon71]

try going to the dealer again, and get the service manager to ring Corts in Bury and ask for Alan, might then be able to get to the bottom of your problem.

Thats my 165 started it as well, the day after it had its first service, but thats another cause for concern as I am not convinced that the Fiat dealer used fully synth oil.

Lost so much power that I was contemplating pulling up onto the hard shoulder, it just wouldnt accelerate or maintain its speed.

Anyway, took it down to Alton Towers with 4 of us in it and it was fine (900 miles in 3 days!) then when I got it back up here to Scotland and on the way down a backroad juddering and lack of power again. It did 50mpg according to my calculations after brimming the tank again which was pretty good for 4 people plus luggage on a 70 mph(ish ;-)) long trip, well I thought so. Anyway back to the problem....

If this is the DPF then its dangerous, its not just a slight loss in performance its basically loosing all power, then a minute later fine again.

Need to decide now whether to take it to the dealer.

I got the same judder in a Bravo multijet after about four months of driving.

It kicks in when doing a steady 60MPH and above, and last (intermittently) for a few minutes, during which you can't accelerate.

FIAT garage initially said it was a DPF regeneration cycle that was supposed to be undetectable, but a software fix was in the works to make it go away. All under warranty. They cleaned the DPF completely and it went away for about eight months.

However, it's just come back and this time the story is different. FIAT garage claims that the DPF is clean this time, and that the cause is a flooded intake caused by 1.1 litres(!) of excess oil (i.e. my fault and the warranty is invalidated).

Crucially, we haven't added any extra oil since the service eight months ago, so I'm wondering where the extra oil came from. The guy made some comment that if the regeneration is interrupted then deisel can (somehow) get into the oil and increase the level - but he says that none of our regen cycle were interrupted and so that can't be the cause.

I'm left with a big bill and invalidated warranty when I don't think I've done anything wrong. I'm highly suspicious that there is some sort of mechanism for the oil level to rise on its own and have to conclude that, somehow, this is the cause of the exess oil, even though the garage naturally takes the position that I'm the one who has added it.

Fuming! Has anyone else experienced this or is it just me?

 

[rambyuk]

(Fuming - nice pun)

I suppose you could equally claim that their forced re-generation process malfunctioned or has caused an ongoing malfunction as much as you over filling the oil (which you didn't).

I'm thinking of getting mine into the dealer now as the odd judder's just not going away despite the higher gear driving and fast road daily commuting - not looking good. Wonder if this is a major 2.0 JTDM flaw?

 

[dcdewick]

Mine was back in to Arnold Clarke's again two days ago. Can't reproduce the fault, but did a "forced regen" twice "which should fix problem the fault for a while". Apparently there's a recall for this problem? The dealer's computer has been away in Italy for a repair, but came back today so I'll be booking in again next week.

In the meantime, I've tried different makes of fuel, including BP Ultimate, but all give the same effects.

 

[Pintopitt]

Yep, similar problem for me in my 2.0 M-Jet. I didn't really notice it as a problem until I read this thread.

I feel my car juddering slightly when 'coasting' clutch out in 6th - and notice the consumption dropping without me applying any throttle. I sort of assumed that the car had enough low down torque to 'accelerate' under the low revs supplied at tick over, putting the drive train under strain and causing the judder. I'd be doing around 40-50 MPH at the time. I could not understand how it seems to be random, sometimes the symptoms are not present at all, even whilst coasting along at much lower speeds.

Also, after this happens - next time I accelerate, maybe after changing down gears I get a distinctive 'cough'. Like the engine miss fires slightly, it only affects acceleration slightly and is not noticeable to passengers but I definitely notice it after a juddering episode. Has anyone else noticed this?

My car is 2009 165T Sport with 7600 miles all since March since the car was pre-registered.

If you read my other post, I love the car but my consumption is pants compared to others forum users. Around 39-40MPG.

Incidentally dcdewick which Arnold Clark you been dealing with? Bought mine from Arnold Clark Springburn in Glasgow.

I'm still getting the problem fairly regularly and have had it so often over the last few weeks that I'm going to take it in to Research Fiat, Nuneaton again next week.

Anyone have any more info on whether this is a known issue? If so I may get in touch with Fiat UK directly before I take it back to the dealer to see if they have any info on this problem.

 

[Plon71]

I'm still getting the problem, getting worse again, despite the best efforts of Richard Corts in Bury. I've given up at the moment, got more important things to worry about.

Hey guys. New member here and joined after reading this thread. I THINK my Bravo 165 Sport has the same problem you are talking about. Basically I first notcied it when I accelerate away from a roundabout in 2nd or 3rd I get a noticable 'kick' (flatspot maybe) at about 2200 RPM. Once I'm thru this rev range it seems to be fine. But recently I have notice it does this at constant speed as well All but 'kangarooing' up the ramp into my works car park in 2nd and At 60MPH in 5th on the motorway the other day did it so badly i had to change down a gear.

I've only HAD the car 8 months, tho I've done 12K miles in that time, so it's well under warranty and my dealer has been very helpful. However they can find NO problem with it. No warning lights. EMS not reporting any errors. And they claim they haven't heard of this problem before. I'd like SOMETHING to go back to them with. Is there a 'favourite' explanation for this so far? Just to give them a starting point. And of course I will report any resolution.

I'm still getting the problem, getting worse again, despite the best efforts of Richard Corts in Bury. I've given up at the moment, got more important things to worry about.

Is this only relevant to the 2litre JTD multijet? Are the cars involved all 16v, or are there any 1.9JTD multijet 8v?

 

[dcdewick]

Arnold Clarke in Amblecote, near Stourbridge. Not entirely confident in this dealer, knew them when I had a Alfa.

 

[Plon71]

Mine still has the dreaded judder, its slowly creeping back to normal, happening 3 or 4 times per week, starting now around 30mph, 15 minutes into my drive to work in the morning, then at any time during the day. Been too busy to take it back to the garage. Anyone else still having the issue, or have any of you had it fixed?

Cheers, Paul.

The 1.6 is 16v as well. However I have only seen 1 person with a 120 model 1.6 mentioning this where as loads of 105 models have been on here.

 

[rambyuk]

Still got the problem despite a 'software update' a few weeks ago

Someone mentioned Redex fixing it, but I've not tried nor not sure about this product.
