Hi everyone, I'm currently in the market for a Mito, but down here in Australia the only option available is the multiair engine.

I understand the earlier models (pre 2012?) had quite a few issues in regards to the oil used and filter changes. Given that buying a Mito in 2020 means I'll be buying one second hand (the original alfa owner decides the fate of the next owner), are the 2013 onwards multiair engines better? Were the issues fixed by Alfa?

Is there anything I should look for in particular when inspecting? Are there any noises which point to a failed multiair unit?

Any help is greatly appreciated.

Cheers!

One thing you can check is to un-screw the oil filler cap and have look at the top of the top Multiair module (just underneath the filler cap), if it is dark then there is a risk that the oil has been contaminated and you have a potential risk for the Multiair module might fail.

Another thing you can check is if there have been a misfire on cylinder 3 or 4. If the Multiair is close to failing it is cylinder 3 or 4 that fail first

I'll be sure to do these checks, thank you!

Does this Mito engine sound right? I've always grown up with the TSpark and 3.2L Busso engines...never really had experience with these new units.

They sound a little truck-like?

They can be a little 'noisy' I've had workmates ask if my MA is a diesel! I know they're taking the mick, it's not that bad, but there's definitely some mechanical noise to them.

That's exactly what I thought!

I posted a video from YouTube in my last post. A video of an engine in a Mito that I'm checking out. Is it not visible?

Hi Couthinho11,

the car in the vid sounds exactly how it should. Its the Multiair unit working propperly. ;)

Issues with the early units: they were falling apart because of mechanical problems. The oil pistons are locked by nuts these came off. But this was an issue on cars before 2012.

Remaining issues are failing hydraulic valves (mostly one of them - there is no priority) of the Multiair units which causes failing of one pair of engines intake valves. So if they fail, the engine won`t run properly (only on 3 cylinders).

I think, these hydraulic valves tend to be "polluted" by old (and black) engine oil. They get sticky. So just be sure to use the right engine oil and change at least once a year and every 8-10.000 mls. And so the pre owner of the car should have done! If so, these valves and thus the Multiair unit should last 60.000 to 80.000 mls or more. Mine (car from December 2012) lasted 90.000 mls

Changing these units is quite an easy job and you can get them i.e. at the alfaworkshop.co.uk or shop4parts.co.uk for less than 550 GBP. In Germany they are 720,- EUR (so down under you should be able to get them too).

This all in mind - the prices for second hand Multiair equipped cars should be quite decent!

So I just had a Mito inspected by a mechanic. He told me it took a little key turning for the engine to start.

He then drove for 2km and noticed that the car wouldn't shift above 2nd (it's an auto tct). For the next 1km however, the car was shifting as it should. Stop/start is also not working.

He tested the battery and found that while the alternator was working as it should, the battery was a dud and needed replacing.

He also noticed oil wetness around the upper/lower parts of the engine, and said it could just be a valve cover that needs replacing or a loose fitting/pipe from a previous service and that it's nothing serious.

Finally, he did not get any warning/check lights or beeps.

Based on these factors, would you say the start up, transmission and stop/start issues are being caused by a dud battery only? Or is there a deeper cause?

Is the oil wetness a major cause for concern?

Should I walk away?

Any help greatly appreciated on this one.

Edit: It is also worth noting that he found no issue with the engine and its performance. Said it sounded and operated as it should, despite a little oil seepage.

Stop/start would definitely be affected by a dud battery. It took 3 days for the stop/start on my sons Fiesta to work as the car had been in a dealers for a month or so. It may also affect the auto TCT.

Interesting.

My suspicion is that as the alternator was working perfectly, the battery may have got just enough charge over the first 2km, meaning the car operated as normal for the final 1km.

The car has been sitting as it is on sale too...which all contributes to a dud battery.

Stop start has never worked on mine, which was owned by my mum from 2 years / 12,000 miles old. No other issues with it, no errors, just hasn't ever stopped on its own. I'm guessing it may also be a battery issue, although it's still going fine on its original now 8 year old one!

You're getting close to borrowed time wit that .. ours latest 9 but it wasn't a stop-start battery ... then it just died. Luckily at home rather than miles away!

Hi there,

yep, start&stop is disabled when the battery is weak. You may also have problems with the powersteering - another german Mito 1.4 Multiair that I know experienced that. But this one and also mine do have a manual gearbox - so I cannot exactly say something about TCT equipped cars. But if the battery affects the electrical powersteering it very likely affects the electro hydraulic TCT gearbox.

If you are about getting a new battery - check ten times you get the right one. My colleague owning the aforementioned Mito had to return the first battery he was supplied by the spare part specialist. With the wrong battery - even new - start&stop, etc. and powersteering weren't working properly.
