Since 2010, with rentals so far, but planning to buy a motorhome in the next few weeks
Howdy everyone,

Following up on our motorhome-buying adventures so far, we hit a major bump here yesterday: after what was supposed to be the last batch of fixes, we were driving the motorhome from their "fix man" garage to the company's main office to make final payment and sign papers etc, and then the "check engine" light went on :-(

We then went to their mechanics garage (which is in a 3rd location) and there they scanned the engine and said the "turbo electrovalve" was bad and needed replacement. They ordered the part from the nearest dealer that had it, in Santiago (Osorno is kinda small/medium city and doesn't have the most "hard to find" items), and it was supposed to arrive this morning but late last night the saleswoman told us they didn't manage to ship it in time :-/

She swears it will be shipped today (and that she will provide us with the tracking number as soon as she gets it, for our peace of mind), and then they will be able to fit it Monday morning. I insisted (and she conceded) that, before final payment, I need it to be revised by the independent mechanic that was recommended to us here in Osorno, so they have an incentive to really fix it well and fast.

The strange thing is, Check-Engine light notwithstanding, the engine seems to be operating completely normal: we not only drove it the rest of the way from the "fix man" to the main office and then to the mechanics garage with absolutely no issues, but also drove it from there to the saleswoman's home driveway (where we camped for the night) with the engine behaving absolutely normal, except for the CheckEngine light and the lettering "Hacer controle motor" ("do engine check" in a literal English translation) scrolling in the panel's LCD display. We heard about engines with "Check lights" on getting onto "crawl mode", but definitely this is not happened here: the vehicle went to 100km/h with no hesitation and kept it there for 15-20mins at least with no noticeable loss of power nor anything.

Has anyone ever seen, or heard about, a fault like that? We're kinda concerned because their mechanic is not a FIAT expecialist (he is a Citroen guy, which we understand uses the same chassis but a different engine than the Ducato 2.3D 150HP we have on ours) so perhaps it's *not* that "turbo electrovalve"... our fear is that this could be just the start of an undesirable cycle of "it's that other part" / order it / wait for it to arrive / test / "it's not that part either" / rinse&repeat, and we would end up being stuck here for longer that we want.

On the plus side, we spent the night in the saleswoman's driveway in a very rural region just outside Osorno, connected to her electricity and with reasonable (but 3G only) Internet, and woke up to the sounds of crickets and birds and some cows pasturing nearby ;-) That is not quite the life we signed on for, but this morning was very close to what we want to wake up to every day ;-)

We hope everything really gets fixed on Monday so we can be on our way back to Santiago and then to Northern Chile -- the motorhome is very cozy, but outdoors it's kinda colder than we like at 50-60 Farenheit (10-16 Celsius, not sure what Units you Brit folks are using right now). One of the reasons we moved into full-time motorhoming is to "follow the seasons" and be as much close to the magic 77F-25C outdoors temperature as possible ;-)

Cheers,

We are approx 15/58 in Manchester at 5pm, few weeks ago it was around 30/88, fear our hot spell is over.

Hope you get your problems solved.

I am no expert but have done a little research and it appears that this valve controls the wastegate pressure on the turbo. They are available here on eBay for around £90 somit doesn’t look as though it is a major problem, is easy to fit so you should be okay on Monday.(y)

Howdy @Xabia, thanks for your help.

I did some research too and found out about something called FIAT ePER; more details on my other post here, but suffice to say it's an automated, VIN-based spare parts database for all FIAT vehicles, and there I was able to find what I think is the exact part (based on the saleswoman description of the part):

It's the part depicted in the diagram as "5",and its details are in the white box that opened when I clicked on it.

What do you think, is it indeed the wastegate pressure valve on the turbo? Does it look like an easy replacement?

Cheers,

Sorry to hear it, hope you can travel out to a warmer area as soon as possible.

Hope you get your problems solved.

Thanks! Right now we are still waiting for the damned spare part tracking code :-/ hope they really shipped it today and that Monday we will really be able to get the heck outta here... not a bad place, but we *really* want to go NORTH (which here in the Southern Hemisphere, means WARMER)! :-/

Cheers,

Its a device external to the turbo that allows the ECU to adjust boost. If access to it is straightforward it will be easily swapped. On the subject of limp mode: most occurrences of limp mode, if not all, are not the result of something dramatic failing. Limp mode is used to force a visit to the workshop because an emissions-related device has failed.

Hi Du,

I don’t think it will be a difficult job, I recently replaced the throttle body on my 3.0 litre Fiat and your job looks a lot easier. Hope I am right, let us know how it goes.

Thanks for your responses, @Xabia and @tonyidle. Will keep this thread posted, hope tomorrow we can get it all sorted out.

Hi Du and Nica,
Aside from your hiccups with the purchase with which I cannot help you, I just wanted to say how envious I am that you are (almost) living my dream in Chile! I travelled by bus south from Santiago with my daughter a few years ago- including a stop in Pucon where the other poster's niece has her restaurant- all the way south and then across and north again up through Argentina, and then back across to Santiago. Once you have sorted the problems please would you blog your journey back up to Santiago and bring back many happy memories for me? Buen viaje!

Thanks @Nangie! We don't have a blog yet and can't promise we will be able to bring up, but we will if we can.

You can easily create a blog of your travels on here, just create a new title and post away, uploading photos as you go.
I think you'd be the first to blog from South America, on here anyway.
You may inspire others to explore the area (y)

Thanks @Figaro, we will try that.

Bit late to the party here but it's a valve that allows (or not) vacuum to act on the wastegate of the turbo..
Because diesel engines don't make their own vacuum on deceleration like petrols do, they need a vacuum pump, usually mechanically controlled and running when the engine is turning..
So to control this vacuum source, you need an electronically controlled solenoid (Electrovalve) to open and shut as desired..
That allows you electronic control of the wastegate.. (the cylindrical thing that's not numbered in the diag above.)
Easy enough to change but just because the diagnostics says that's the fault, I wouldn't trust it as far as I could throw it.
Any time boost levels are either under or over desired target boost pressure, the ECU quite often flags that sort of code.
HOPEFULLY, the mechanics there are not just a bunch of "but the computer said...." types and actually do some proper investigation first!

Good luck with it, either way, it's probably nothing major to worry about even if it wasn't "fixed" by the time you have to either buy or leave..
I'd buy it anyway but then I do know my way around vehicle electronics :D

Howdy everyone,

Many thanks for your help and support.

Today the part arrived, was replaced and then the motorhome was inspected by my mechanic: he approved everything "suma cum laude", so we closed the sale and are now parked in a truck rest stop just north of Osorno.

We're very happy in our new-to-us home! ;-)

Our plan is to drive all the way to Santiago to finish our businesses there and then go a bit more North to somewhere warmer... Then November we will drive South again all the way to Ushuaia to start our Panamericana trip.

Sorry for the brief post but our internet access is not good. Will try and keep the forum posted on our progress along the way.

Cheers,
-- Du & Nica.

Thanks for the encouragement, folks! We started out already, let's hope we can find the time (and the internet access) to keep it up:
