hi, i have a 1997 bravo TD 100.

it has 90000 on the clock,
it also has no power!!
changed the fuel and air filter, no difference!!
cant find a MAF sensor, its a manual fuel pump so not sure if it has one?
also the turbo makes a fairly loud whistling, could this be a jammed wastegate or is the turbo allways loud?

also where is the wastegate in relation to the turbo itself, ie on top?

any help would be very much appreciated, was looking forward to owning a bravo but mine is junk!!

cheers
 
Ah, bugger. What be the problem with it? think i could get it reconditioned for less than a ton?
 
i have found one, its a JTD 100SX, any one know if they are compatible? i will try my pipes tomorow lol! thanks for all help, much appreciated, keep it coming! i heard someone mention and EGR valve at BOO, any knowledge on this?
 
that'l be a no then, i checked the intercooler pipes, seem to be ok. the whistling seems to be coming from where i would imagine the wastegate to be, but it looks imposible to get at, do you just unbolt the heatshield and it simply comes away to reveal the turbo, or is it more nightmareish? great info so far, nearly gave up and took it to fiat, £67 for a troubleshoot, STUFF THEM! thanks!
 
The TD100 turbo is a bit of a whistler anyway, so you should not go on noise alone, unless its really load and doesent go away when the revs get up. Make sure there are no cracked / loose / split hoses, or holed intercooler. You can do a basic check for boost by squeezing the hose from the intercooler to manifold with your fingers, and giving the engine a good revving, you should feel the hose "fill out" a bit under the pressure. but you really need a boost guage to check properly, as the turbo only really works under load (i.e. while driving).

Is there any black smoke when you floor it ?. This could also be a fueling or EGR problem.
There is a MAF on the TD100, but it doesent have anything to do with the fueling or power.

dont go replacing turbo's without being sure they are knackered, as they are hard to find and expensive..
 
i have checked pipes etc, did the squeeze test and seemed to give out a little, not as much as i expected it would. if you want to picture how slow it is: there is a half mile (at least!) stretch where i live, i come onto it doing 65 in fourth, by the time i come off the strait i'm only doing 75-80 with my foot in the engine bay, my SEIC used to do 100. (dont worry i do this at 3am and make sure its clear before i boot it)
i am thinkin it could be the wasegate, how would i check?
i unplugged the AFM just in case, no difference!
 
Ok, so the squeeze test showed at least some pressure so no major holes anywhere. difficult to fully test wastegate without removing turbo but make sure actuator is moving / stroking fully in and out, and the bellows inside is not leaking (by pressurising it). You could buy a cheap pressure guage that can read up to 1 bar (15 psi) and attach it via a t-piece to either the actuator pipe on turbo or at the connection on top of manifold. You should be seeing nearly a bar when floored and the turbo kicks in around 2000 rpm

The EGR valve may be passing, so remove it if possible and inspect, and pressure test by blowing through it on manifold side. If it seems ok, disconnect the actuator pipe from the EGR valve and block it up with something, and test drive again.

Does the engine run normally otherwise ? What about smoke ?

Sounds like FIAT didnt do much of a troubleshoot, did they actually take it for a spin or anything. bloody time and money wasters..

They told me to come back in ten days because their "MACHINE" was at fiat getting calibrated? WHAT THE HELL DO THEY NEED A MACHINE FOR, THERES NO ECU!!! is what i said lol, i only nearly given up so far, not yet!

to be ohnest i have no idea where the EGR is, i disconnected the AFM like i said, but this is my first bravo and i have no manual.

when i first start the car there is some white smoke which is one big puff then clear, nothing apart from that.

I'm gutted cos i've got a host of goodies being saved for me but i'm reluctant to buy them until she runs right!

One of the parts is a boost gauge for £20, could this help the analasys?

thanks again
 
Hmmm, I get the picture of your case dude. But to be honest with you (this coming from a fellow TD brava owner), don't expect much from a diesel brava when it comes to performance.

Once it his the 100km/h speed, the brava will just increase speed slowly. However, it does worry me that you only went up to 75 (miles i assume) in half a mile.

Are you by any chance leaving the engine revved too low (i know its a stupid question by wth):confused:
 
Ok, so no smoke other than at start up which is fairly normal. The EGR valve is located on the top right hand side of the intake manifold (obviously you need to remove the plastic engine cover). What is the fuel economy like (see what mileage you get from a full tank) ?.
BTW, there is an ECU on the TD100, it controls the EGR and timing advance, so a problem here could also result in poor performance.

the boost guage would certainly help in diagnosing this problem.

Gabaj, the TD100 will fly up from 60 to 80 and up in a few seconds.. its not a poor performer

If you cant figure out anything i would suggest finding a good diesel specialist garage who should be able to help.
 
itll do 40-55 mpg,
did 0-60 in 21 seconds (with a bit of wheelspin) CRAP!!
my mate had a JTD 100 which would do 115 mph on the same straight?
my 306 dturbo would do 110 on the straight, and full war it would do 130, i havent been passed 90 in bravo?
i think i've been robbed, if fiat cant sort it i'm giving up and getting a 2.2 TD ZR on finance, 150 bhp lol!
plastic cover is off the engine, i'll have a look tomorow and try and take some pictures.

the sump plugs a witch to get off aint it!!!
ruined my TORX!!

you need a hex bit. there's a standard size for most fiat sump plugs and also the same size is used on gearbox drain plugs. ask at a motor factors and tell them its for fiats, they should know the size (cant remember off the top of my head)
 
Sorry, think i meant HEX but got mixed up, fitted like a glove but it was a crud cheap bit which split...
smacked my hand on subframe, unleashed verbal diorhea before giving up!!

Fix It Again Tomorow!!!!!
