Help with Alfa 147 Jtdm - MCUF & VCD

Help! Hi I have an Alfa 147 Jtdm 16v. It's a 55 plate and has 90k on the clock. Last week I had to jump start it due to a dead batt. It failed on me again a few days later so I have now replaced it with a new one. Whilst this was happening the MCUF & VCD fail come up on the dash. The car now runs 70% in limp mode and feels like it mis-fires a lot and then the rest of the time it runs fine. (Still with the warning signs on the dash) Before this started there was quite a bit of white smoke, which smelt quite strong on start up which now seems to have gone. I have looked on several forums but I can't find any with the same problems as I'm having. Any help would be much appreciated.

They're known to behave oddly when the battery is low/unhealthy... I'd get a replacement battery installed, clear all the fault codes, and see if any of them come back... Could just be a bad battery causing gremlins!

Hi, thanks for your response. I have put a new batt on there so my next step will be to have it plugged in & see what comes up.

Do you have any idea though why when its stuck in limp mode the engine feels like it massively mis-fires & can only just make it up a hill but then out of nowhere it runs perfect for a little while without being restricted.

Is there anything else that I could check or eliminate before having to take it in?
