Markatlee Posted August 30, 2019 Share Posted August 30, 2019 We have an Eurostar, 3.0 litre 160, camper with a fiat. Ducato basis. Made in 2010 She drove well enough for the first year, she began to smoke terribly, a black thick smoke, after much searching the egr system was replaced , since then the unknown problem began, she drives well for about 200-300 kilometers then when slowing down, to around 60 klm or driving she starts to malfunction, the accelerator pedal actually moves up and down and from nearly stalling to hard accelerating making driving a nightmare to be honest. We have so far had a whole new egr fitted, fuel injection system, clutch,and gear box, a new on board computer, which apparently has to learn, a diesel expert has looked at it, fiat has given it a diagnostic, 3 garages have given it a computer analysis, it always says that there is nothing wrong. Does anyone out there have any ideas? She is a 3.5 ton, 7.5 meter camper Link to comment Share on other sites More sharing options...
Alanb Posted August 30, 2019 Share Posted August 30, 2019 Modern vehicles are drive by wire as the accelerator is concerned. The accelerator pedal connects directly to a duplicated variable electrical resistor unit, which also contains the pedal return spring. There is no way that the pedal is going to move independently, unless perhaps the return spring is broken. Alan Link to comment Share on other sites More sharing options...
Markatlee Posted August 31, 2019 Author Share Posted August 31, 2019 Thanks for the reply Alan, that's what everyone says, yet the pedal really does move on it's own, it revs as the pedal moves by itself. I shall ask them to check the spring as you suggested, thanks for that, the garage now wants to bring in a software expert, even though we have just had the onboard computer replaced! Thanks for the suggestion, I shall pass it on to the garage. Link to comment Share on other sites More sharing options...
Markatlee Posted August 31, 2019 Author Share Posted August 31, 2019 Do you think the problem could be the electrical resistor unit? Link to comment Share on other sites More sharing options...
Markatlee Posted August 31, 2019 Author Share Posted August 31, 2019 Would this problem show up on a computer diagnostic sca or test? I have had 4 of those so far, tray all say that there isn't a problem. Link to comment Share on other sites More sharing options...
Billggski Posted August 31, 2019 Share Posted August 31, 2019 There was a post exactly five years ago, 31st Aug. 2014, about a similar issue which was discussed with "euroserv". https://forums.outandaboutlive.co.uk/forums/Motorhomes/Motorhome-Matters/fiat-ducato-2-3-throttle-actuator-condensation-issue/35958/ Link to comment Share on other sites More sharing options...
Markatlee Posted August 31, 2019 Author Share Posted August 31, 2019 Thank you very much, I shall be passing this information on to the garage. Link to comment Share on other sites More sharing options...
Derek Uzzell Posted August 31, 2019 Share Posted August 31, 2019 Like Alanb I find it hard to imagine how there could normally be ‘feedback’ from the motor that could cause the accelerator pedal to meve of its own volition. The only thing I can think of that MIGHT cause such movement is if a ‘mechanical’ cruise-control system had been fitted that physically connected the pedal to the motor using a cable, but that’s most unlikely to be the case with Mark’s motorhome. (The only “Eurostar” motorhomes I’m aware of are/were built by a company called Apollo and marketed in New Zealand and Australia. Is that relevant here?)

Markatlee Posted August 31, 2019 Author Share Posted August 31, 2019 Thank you for the reply, my autostar was built iin France I believe , I have seen a few as we have driven through France. 2010 was the year of production. Link to comment Share on other sites More sharing options...
ColinM50 Posted August 31, 2019 Share Posted August 31, 2019 Hate to post this but bearing in mind how much trouble you've had with it and all the money you've no doubt spent, is it maybe getting to stage where you cut your losses and move it on? NEC show next month, maybe a trade in? Link to comment Share on other sites More sharing options...
Will86 Posted August 31, 2019 Share Posted August 31, 2019 When my computer keeps doing a wobbly, I have to dismantle all the connections then re connect one at a time from the start point. Spurious emissions come to mind here .......................... needing similar treatment ? Link to comment Share on other sites More sharing options...
Derek Uzzell Posted August 31, 2019 Share Posted August 31, 2019 Markatlee - 2019-08-31 8:58 AM Thank you for the reply, my autostar was built iin France I believe , I have seen a few as we have driven through France. 2010 was the year of production. Autostar is a French manufacturer with a factory near Quintin about 20km south-west of Saint Brieuc in Brittany. The marque has an excellent reputation in France for good build quality and innovation and has been part of the Trigano Group since 1998. Autostar commenced motorhome production at Quintin in 1985, but has taken little interest in the UK market. A few Autostars were ‘officially’ imported to the UK for a while in the early 2000s and there’s a reference to this here https://www.ukmotorhomes.net/reviews/motorhome-reviews/autostar-aryal-9 I believe Autostar chose not to build right-hand-drive models, which must have had a negative impact on potential sales in the UK.

Markatlee Posted September 2, 2019 Author Share Posted September 2, 2019 Yes, the camper is definitely a French production, you do see a few of them in Europe. Mine is a left hand drive as I live in holland and drive all over Europe, until this issue that is. Link to comment Share on other sites More sharing options...
Markatlee Posted September 2, 2019 Author Share Posted September 2, 2019 We are going to sell it, the magic has faded, yes we have spent over 6000€ so far, we cannot sell it until the thing is mended, it wouldn't be fair to sell it as it is. We did drop her off at a dealer recently, a dealer, camper garage, he has said that it isn't good and would not sell it, Ithis is garage number 5.

Keithl Posted September 2, 2019 Share Posted September 2, 2019 Markatlee, The forum expert on Ducato's is Nick Fisher (aka Euroserv) but he does not appear on here much of late. Suggest you either PM or email him and ask for advice https://forums.outandaboutlive.co.uk/forums/view-profile.asp?action=view&uid=3275 Keith.

onecal Posted September 3, 2019 Share Posted September 3, 2019 Did they replace the wiring loom ? Sometimes moving it when fitting other parts may look like the problem is solved (for a short time) Water ingress can cause problems to some components but Fiat are well aware of this Get your wiring loom changed and hopefully it should solve your intermittent problem.
