Hi Guys!

I've got a really bad problem with my GT that no garage can seem to sort I've taken it to 2 garages now.

Started off slightly misfiring in the morning, which gradually got worse and now it cuts out in the morning and also fires out black smoke out the exhaust. It's fine when warm but not cold! And has 'Motor Control System Failure'

So... ended up taking it to a garage who changed the glow plugs, EGR valve, fuel filter, ran diags, cleared codes, and it still happens. So, they then blocked off the EGR valve which sorted it for a bit although I had Motor Control System Failure still.

Now, last week went to another garage who changed the turbo on it because they said it might be that.. I'm really stuck now I just don't know what to do to get this stupid MCSF light off and get it running normally again :( so so so stuck please help it's costing me hundreds of pounds every time it goes in and I can't afford anymore :(

Cheers

Lee

sounds like injector to me as we get that alot.

next time you take it to a garage check the flow correction between the injectors and there you shall see which one is playing up :)

If the fault codes were cleared and the problem persists (with no fault code shown) i would definatley go down the injector route :thumbs:

Has anyone ran a compression test on the injectors? As everyone else mention it does sound like injectors.....also the MAF might be worth a try too.

Codes read, but random parts changed anyway? - take to an Alfa specialist is my advice...

Errr correct me if I am wrong but having EGR blocked off should show the engine management light.

If it's been blocked like you say then you also need the ECU re-mapped to remove the EGR from the code.

If that has not been done you will always get the light coming on regardless of how well the car is running or not.

At the risk of sounding a bit pedantic
: Doing a forum search on MCSF errors and failures would have thrown a lot of cheap and chearful fixes up that even the most basic of DIYer could follow and would have saved a fortune in obviously an ill informed mechanic's bill...
Sorry but there it is....
For all to use, glean information from and use..... Kudos goes out to the very unfortunate yet very well informed members who have been there in the same situation and had the foresight to post their findings in an effort to help fellow members:thumbs:

Justs makes me glad to be an anti-Alfa diesel advocate when it comes to reading posts like this...:rolleyes:

I really hope you get this sorted out though Lee and I don't mean it to sound rude and ignorrant...
Start at the beginning, clean the EGR valve, the solenoid etc. Check your pipe work for splits, then disconnect the MAF and see if that rectifies the misfire and spluttering... It sounds like you have a culmination of minor faults that are making up a big one...

There are plenty of tutorials to help you on how to do all this and the best part is, all of the above is cheap to do and will help you eliminate one part logically at a time... Don't forget to remove the EGR blanking plate... As John Says above me.... It will only throw up a fault anyway if your ECU hasn't been re-mapped to ignore it....
Good luck:thumbs:

makes me laugh.........how people blame the turbo or stuff like this

i had a rough running gt jtd, motor control light on and fuel gauge at zero as well

take engine cover off........number 3 injector was my fault....or to be presice the connector...full of muck and it was still iffy after a clean........if i pushed the connector in it would be fine but letting go made it run rough, so its now zip tied in tightly and it as been problem free since november !!!!

just push the sockets in one at a time with engine running if engine tone changes that the problem connector

hope it works for you !!

I don't disagree with you there.....trouble is we can't all afford the thirsty V6 or those TBi's (which are just as thirsty!).

Also, alot of these new petrol engines use direct injection and turbochargers from diesels so in turn will start to have similar issues. The only benefit of a modern petrol engine over a diesel now (from a reliability perspective) is that petrols are less sooty so 'should' be more more reliable even with all these new fangled bolt ons they now have.

Bring back the old skool petrols is what I say!!!....oh hold on....we have to be all green and run low emissions don't we......arggghhhhh:(.
