Technical Help! No vacuum to the turbo actuator

[multiplied]

hi , you sure overboost valve tubes are now correct way around?, i only ask because the wrong way might make all these extra faults come about.
these new car faults need clearing again & taking car for a spin. do faults occur while driving or just tick over?, does management light come on ?.
u need the fiatecuscan so u can delete the errors/read codes without shelling out each time

 

[millymoon]

Hiya, we double checked a diagram we got from my partners friend and the hose is definately on the right way now apparently. When he attempted to try your trick with the tee, he accidentally brushed past it and it literally came off! so it clearly wasn't on properly in the first place. As soon as the codes were cleared the new codes came up. previously we only had P0236 but now we have a whole bunch of them! And apparently the management light is on.. he thinks, but is not 100% sure - how can we tell? How much are the fiatecuscans and where would you buy? Have checked ebay but no luck. Is there a cheap decent alternative? Sorry, still so many questions...

hi millymoon,
sorry, only just got back to this.
you can download fiatecuscan completely free, just google it .
all you will need is an 0BD11 Cable off ebay (approx £16 delivered).
then just read the install guide on the fiatecuscan website, it tells you how to set up the software correctly so it will talk to your car .
my cars running great still, had a minor setback with new egr stuck open, but blanked off now & going fine.
hope you get your multi fixed

 

[millymoon]

Thank you. You really are a life saver. Ecuscan downloaded and cable on order. The ECU wasn't reconnected properly when we cleared last time so were advised it probably wasn't earthed properly and that may have caused the fault codes - I certainly hope it's that simple!!! Boyfriend is convinced the car should be fixed now so we will wait and see. Ex is down again next weekend so one extra head to scratch. Fingers crossed as always but here's hoping....

Hi peeps !

I hope Im not to late to the party !
somebody kindly linked me here, from one of my own threads ! I like to keep this one alive for a bit longer.

Im suffering pretty the same problems, but want to double check a few things
I picked up my car a few days back, as soon as I drove away there is no power ! The car crawls I have to work every gear just to get up to 30-35 !!! an thats on a flat road !

So I have absolutely no power, But the engine seems to tick over fine, sounds sweet tbh. When I 1st picked up the car it was reving max to 4000-4500
But no engine management light ??!!
That slowly dropped, got recovered in the end, the guy who recovered me gave me a little false hope maybe. He said it shouldnt be your turbo, engine sounds great idling. and the car was in good nick lol. He rekoned throttle sensor ???

One observation when I got home was it wouldnt rev above 2000, now I did try it with out the maf on the morning, and it revved upto 3000 ! But now it wont rev over that 3000.
1st garage wrote me off, and said turbo, and scrap it :bang:
now its with another mechanic who took the turbo off, said the turbo seems ok, just no vacuum going to the actuator or waste gauge ( I forget now)
Im hoping its going to be same problem multiplied had..........

Im interested in finding a bit more about how the vacuum system works overall !!?? As I noticed the second time at the mechanic that even after a good 20 miles driving my front brakes have not worked at all !!!!

( noted because the car has been stood for 5-6 months, but still ! are they just completely seized ? or is there something more to the braking system I should know about, that may be connected to a vac problem ! )

Would really appreciate any info ! I know I have me own thread going on but im desperate.

How have you got on millymoon ???

Im wondering if even with your vac problems, did your cars still have normal power up to a certain point ? Because mine seems complete flat it has to crawl up to the 30-40 mile point, and only through working the gears !!!

the guy who recovered me , said " its in get you home mode ??? not even limp mode ! but get you home mode, is there such a thing !!!

 

[millymoon]

Hi yoshi2u, welcome to this ongoing saga/nightmare! Mine has exactly the same problems that you mention even down to the brakes!. We are still waiting to have the fault code cleared from our last session of messing around with the car. The fiatscan works but the OBD2 lead does not!:bang:

If you read the various postings on here, Multiplied has successfully managed to find a solution around the problem and it was whilst trying replicate him that we found one of the tube connectors had been connected upside down! We now have vacuum to the turbo actuator but are stuck in limbo until we clear the code to see if this has worked.

Strangely our mechanic also told us our car wasn't in limp mode!!!?? The best advice I can give is to check ALL of your tubing connections for vacuums or holes/splits and follow Multiplied's instruction. It may simply be that you drove over one of our millions of potholes and a connector came loose. Hope it is that...

Failing that stay tuned, this one is still ongoing...

 

[Yoshi2u]

Ill be getting my hands on the car tomorrow, its with a friend/mechanic !
But he's only plan me thinks is to get a MAF from the scrappy's ! As happy as I would be if this solved it, Im not to confident.

I will endeavour to check every hose and connection myself !

Like I said I dont have any management lights on ! or couldnt find any fault codes when we did a diagnostic ! Not sure if one kind of diagnostic software might show something another wouldnt ?? Think Im getting ahead of meself.

Well Ill keep you informed of how I get on too !

 

[millymoon]

It must be more irritating NOT having a management light as you have no clues where to start! I really hope it is a simple fix for you. Will be keeping my fingers crossed for you

 

[Yoshi2u]

Ditto !

I hope we both can get to the bottom of this soon !!! I do have a time limit

After that I dont know ! The cars at mine an my girlfriends here in Redcar, But dont have a drive or owt !
But if this job comes up in the next week or so in Derby, I could maybe utilise my parents of street parking space ! well if I could get the car there in the 1st place lol. hmmmm dont think Id be going down the m1 at 30mph ! And I actually need the car for a new job !

Ahh such if is life eh ! always likes to kick you when your down.
Im disheartened by the 1st garages response ! which was just to fob me off !!! And Im not to confident of my lastest mechanics expertise

So right now Im feeling a little isolated on this one, and feeling like im gonna have to try and solve it meself !
Id borrow the money and take it to someone if i thought they were gonna be able to solve it ! all except Fiat.....lol My finances deffo dont extend that far !!!

Keep us informed how you get on
And as soon as I learn something new Ill keep you informed !!!!

 

[millymoon]

Have come to the conclusion that most mechanics are crap and a complete waste of money. I honestly think that given you don't have a management light on, one of the pipes has come loose or is blocked. We borrowed a vacuum guage to test ours but multiplied has put some great ideas on here for checking so would def check all these first before shelling out any cash - it would have saved me a fortune if I'd done that first - as all the mechanics I took it to replaced part after part after part - and STILL the car is broken!

Can anyone advise re: the OBD2 cable - it doesn't seem to pick up all the ports for the fiatecuscan. (it only reads two out of four ports) is it likely to be a dodgy cable - or is it likely that this cable isn't suitable for my car???? Any thoughts gratefully received.

 

[Yoshi2u]

Hiya millymoon

Any news ???

I got my car back from a sort of friend/mechanic/muppet yesterday, and.....

It wouldnt start, even with a jumper pack, and then from another car, just wouldnt fire up. Sounds likes its being starved of fuel. He seemed like he knew he had f***ed something, that and he just couldnt give a f*** ! :bang:
his little muppet side kick was telling me oh, it wouldnt even go over two miles an hour !!!

I only have myself to blame, live and learn as they say. And I really am learning !
the hard way. I even had to get recovered from the garage, lol . I wasnt going to wait round for him to do anymore damage ! So now I am further away from light at the end of this tunnel !
Ive had the battery on charge all night, and Im going to see how it fires up in a bit. and take some picture to try and get some advice.


So things are getting worse not better at this point. Through desperation, i called a local mobile mechanic, He mentioned a sort of local firm, who are very well known diesel specialist, the best in the business, and not to expensive. Only thing is I cant get it seen by them until the friday after next....

I asked him if he would come and look anyway, just to give me an opinion, but he was saying things like hmmmmm, starter motor, or injectors, so on so forth lol

What can I say, they always want to go for the big stuff, Im no mechanic thou, so i cant say it isnt, but how can they rule out something very small too !

oh im babbling now ! time to go and do summat.......


Well I hope you have some good news soon !
keep us informed how you get on !!!

 

[millymoon]

Hiya Yoshi2u - can't believe how fast your car has gone downhill since the mechanic had it!!! I think we're all in the same boat with little money to spend on our cars but needing to fix them. It certainly helps if you know what's wrong in the first place... This forum has some fantastic people who give great advice so I really hope someone can come up with some suggestions for you. But if your car didn't have the problems it has now when it went to the mecahnic then the donut almost certainly broke it! Not good... Keep me posted

 

[Yoshi2u]

Yup ! I messed up, its me own fault really, live an learn an put it all down to experience. I have had some brilliant help support and advice on the forum, but theres only so far it can go !

Ive had some good news and bad news kinda ! the good news aint about the car unfortunately lol. I got the job at toyota in Derby, thats taking three months of jumping through hoops to get :slayer:

But that now means I have no time to fix the car :bang:, that is also a 150 miles from Derby...

I may have to pull a little swifty, and call out recovery to get me to Derby, where I have lots of room and tools to work on the old girl.
Ive had nothing but knocks and sh*t advice, telling me to cut my loses and scap the car, I dont think so lol
So I just winging it at the moment !
But I will not give up !!!!!! never !
You can take my land , you can take my money, but you'll never take my FIAT !!!!!!!!! Ahhhh !

You got anywhere with yours millymoon ???
I hope you get a lucky break too !!!

 

[millymoon]

Unbelievable! Have just had the 6th Mechanic look at the car. He cleared the codes and found the wastegate remains open when the car is revved. He then took the car for a drive & thought it might be the fuel filter. A quick look under the bonnet and he noticed the intercooler pipe wasn't blowing out. Hence intercooler is probably blocked.

He's sure if I clear this, the problem will be solved as no more codes coming up on the diagnostic thingy!! This took him all of 20 minutes and he didn't even charge me!!!

Will hopefully clear the intercooler this weekend so will let you know if it really is the problem. Everything crossed!!!!!!

 

[millymoon]

WOO HOO!! Car is finally FIXED!

It was definitely the intercooler. Apparently it is standard practice to clean this before fitting another turbo and this clearly wasn't done. We were told to expect some blades and other bits of the old turbo, but we certainly didn't expect to find a paper towel crunched up inside! Bad workmanship all round really. Would highly recommend anyone with the same problem to check all the tubing first - and don't forget to check if it's on the right way round! Get someone to rev the engine whilst you check. The mechanic simply looked down and noticed the tube from the intercooler was starved of air and was contracting like it was being sucked, rather than expanding like it was being blown up. Am really glad the problem has been solved after all this time, but really not happy about all the numpty's passing themselves off as mechanics and charging for the privilege

A HUGE THANKS to all you guys for your thoughts and suggestions. I really don't think I would have kept pressing for a result had it not been for you

 

[momoe]

I think you should be congratulated on your perseverance, I'm not sure I would have stayed the course.

Your last mechanic sounds like a diamond, post his details up in the recommended garages section if you get a chance. As you've found out, good un's are hard to come by, paper hats are two a penny.

 

[millymoon]

Thank you Momoe. But it really is down the great people on this forum pushing me forward with new ideas all the time. Priceless! Will definitely post the mechanic's details on the recommendation page. For those following this post it was all down to Geordie and Phil who can be found at Nunney Catch Garage, Frome, Somerset, BA11 4NX absolutely top blokes. Poor Phil got roped in whilst on the school run...

I recently changed a turbo and while cleaning out the inter cooler pipes (inter cooler was replaced) found a huge rubber grommet in it...no wonder the turbo had bent fins!

 

[multiplied]

hey millymoon, so pleased you now have yours fixed!, ours has been spot on since, just done 180 mile round trip into snowdonia camping at weekend, car driving perfect (all fingers crossed & wood touched!).
one footnote- i had a hick-up few weeks back with total loss of power, blanked off egr valve & car went better than ever. these cars dont like egr valves, i would highly recommend anyone to blank it off as they fail all the time

 

[jwmultipla]

Hi Millymoon,

Been following this and i'm glad you finally got to the bottom of it after all the traumas! I must say though, it is standard practice to clean out an intercooler when the turbo goes so this realy goes right back to the start when the mechanic that did the job fitted the replacement turbo but did not clean out the turbo and more importantly check to see if what he had fitted was creating boost pressure. As you say your guy that fixed it noticed that the intercooler pipes were not pressurising. also when a turbo fails there is sometimes a possibility that the turbo will dump huge amounts of engine oil into the intercooler. this oil lays there until the engine is started, the new turbo creates pressure and heats up the air inside the intercooler, this in turn warms the oil that was left in the intercooler from the failed turbo and eventually it makes its way into the engine via the inlet manifold. this will cause the engine to run on the oil vapour rather than diesel so turning off the engine with the key does not make it stop. As the supply of oil is uncontrolled the engine will rev up to speeds never seen before and usually destroys the engine! so in that respect you were lucky that this did not happen. Hope the car behaves itself from now on!
