Technical Turbo Boost

[Mr Brown]

My other half (mrs Brown) has a Mk3 Punto GT last week the injector light started coming on, now it's on all the time and the turbo isn't boosting properly the boost is not even half way (about 0.5 bar). The car isn't missing or juddering, it seems to run ok but with a lot less boost any idears

Could be the ECU Trying to limit engine damage by reducing boost pressure? You need to get the car hooked up to some diagnostic kit quickly.

i'm quite sure i read something up about fiat ecu's having a "get you home mode" that kicks in if there is a fault in the engine to prevent there being any major damage done to the engine

 

[Mr Brown]

Had a look last night to check for split hoses ect everything ok, thought I'd check the oil (guess what NO OIL) filled it up took it for a drive, within 5 min light went and turbo boosting ok. Also had a word with mrs brown about checking the oil once a week

 

[ChrisUK]

lol that could of been baaaaad!!. Also i didnt know they did a mk3 GT

 

[klaus23]

yeah if they do sell a MkIII GT can you let me know where?

I was checking the transmission dipstick for the first month of coupe ownership When I checked the correct one, The car was about 2 litres down on what it should be I was very dumb, And very, very lucky

 

[Punto Power]

wot i think he means by m3 gt is the engine, they made three slightly different engines in the gt series, unfortunately only in the mk1 body shell

Bought a punto turbo a wee while ago and this has just happened with me the light goes on and off. going to check the level of oil. does a turbo timer affect it in anyway?

 

[custard]

nice to see a healthy use of the search there all a turbo timer does is keep the engine running to allow the turbo to spin down without loosing its oil feed.

thanks maybe cud be the oil feeder to the turbo be leaking causing it to drop in oil? shudnt be hard to fix tho?

 

[custard]

well any leak will drop oil. lots of other factors though.
if the cars driven hard oil useage will increase as with things such as engine wear.
have you noticed it using much oil?

 

[MacK-MinTeD]

no just come on there. i thot it was sumthing to do with the injectors but as i read its the level of oil i presume

 

[custard]

well if its the oil level indicator get it checked ASAP. especially on yurbo cars as the oil is critical for the turbo.
should be checked weekly for sure and changed more frequently than N/A engines

 

[MacK-MinTeD]

very true. cheers will get it checked out

Weekly check at the fuel station - tyres (remember spare!), oil, coolant, screen wash.

Once had someone remove the oil filter from my parents car 'for a laff' Was a 1.4ie tipo and managed about 8 miles, leaving a thin line of engine oil from our house until about 4 miles when it stopped. Car managed to get nearly all the way back home until it siezed up :bang:

Had to remove the bottom end, replace all the shells, wet n dry the pickup off the crank and refit. The car got going again and used less oil from then on until it was given away!

yeah if they do sell a MkIII GT can you let me know where?

Are you gettin the mk's off the cars confused? Are you wanting to know if the Mk3 punto GT is available or did you not know that there are there types of mk1 punto GT's?

 

[MacK-MinTeD]

no luck the management light is still on! Gona take it to fiat and get it diagnostic check and see wot the matter is
