Hopefully it's fine now. I don't know if the O-ring was the problem though. Were there any oil leaks?
Interestingly though, comparing the old vs the new filter in this article and you see a difference in O-ring shape.

Yeah, the photo of the new filter gave me the clue. Forgot to mention, oil is leaking slightly from the bolts that hold the ignition coils in place on cyl3 and 4. The plug holes itself are dry. Weird

Think I’ll pull mine out at the 30000kms oil change. Ours was bought new - first change at 800kms, second at 7000, third at 15000 and fourth at 22000.

15000 is too long imo for these highly strung engines with such a small sump capacity.

 

My G is a 2011 version. The attached photo shows the MA filter replaced as routine at 48,975 miles. The o-ring looks flattened but perhaps not as much as yours. The mechanic who did the work (Pud237 on here) gave the old filter to me and said that a wash in petrol and it could be reused if I wanted to save money next time it was changed. This was in 2016 when the belts and water pump were replaced. I had no multiair problems until 2018 when the engine would momentarily misfire and the engine management light came on and DNA was disabled. In-between the engine ran fine and drove ok except for the lack of DNA. A read of the fault codes indicated P1061-71 stored (rather than active) which is "cylinder 1 UNIAIR actuation electrovalve signal - Actuator stuck". I was advised the engine was ok to use but take care, do not drive it hard and if the problem got worse review the situation. To cut a long story short I had the multiair unit replaced as a confidence measure.
The whole story is detail here https://www.alfaowner.com/Forum/alfa-giulietta/1159586-help-error-message.html

I suspect that if you are getting both P1061 and P1062 codes then actuators on two cylinders are sticking but not necessarily at the same time as they show as pending not active. This might be due to a lack of pressure rather than mechanical sticking. If your suspicions are correct then you should have no further problems but my advice would be the same as was given to me. Take care, don't push it too hard and see how it goes.

All the best and fingers crossed it is sorted.

 

Interesting information, thank you! You didn't by any chance have a look at the old failed unit to see what was wrong with it? I think I will be preparing myself to bite the bullet and replace the unit because i really like the car and didn't buy it to drive sensible really [emoji28] Btw, my local Alfa dealer didn't even know the little filter exsists, had to send them the part number so they could order a new one. [emoji34]

I did not get a chance to see the old unit. It was changed by Alfaworkshop and the nearest I got was seeing the mechanic dump it in the scrap bin. In all honesty I don't think there would have been anything to see without dismantling it and they do not have the time or need to examine the old units.

 

FYI I sold my broken multiair on eBay for ~70euros plus postage.

 

About Multiair Problem I faced two times this problem specifically 4th cylider low pressure.Some mechanics they said you have to replaced multiair unit which too expesive for me then I researched some oil specifications with all brands then I decided to use mobil 1 0w40 oil. First I got unit cleaned with filter then I used mobil 1 0w40 so problem was solved. If you live cold places I certainly advice use 0w40 mobil 1 its better than others especially with cold engine oil fluidty. Try this way maybe you would be lucky as me.
Have a good day

 

Multi Air Problems. I have Guilietta 1.4 170BHP MultiAir Turbo. Have had problems with misfiring and stop/start and DNA switching off.

Before expensive replacement (Genuine £1000+ plus fitting) was advised* that it was probably and issue with the actuators sticking/gummed up

Advised to have complete oil change. and replace with Petronas Selenia StAR P.E. SAE 5W-40. FIAT 9.55535-S2 - ACEA C3. As specified on Page 227 of hand book. After a couple of repeats no issues for past 6 weeks.

(*My mechanic was an F1 mechanic before he grew up ! So he does know what he is talking about)

This is expensive oil and not all garages stock it or will even buy it in (Have to purchase in bulk and very limited call for it).
M above may have been OK with Mobil 1 0W-40 but really do recommend using the Petronas product specified.

Any updates on this? Is it still running OK?

 

Hi, my multiair needs replacing I have been told by Alfa Tech Huddersfield.
they told me cylinders 1 and 3 are misfiring and a new multi air is required.
I have silver cover with warranty wise is this covered? The warranty states the following:

ENGINE:
All major internal moving Parts of the cylinder block including; crankshaft, camshaft, pistons, connecting rods, balance shafts, gears, oil pump and including the cylinder head, engine block and liners (but excluding; variable camshaft timing units (Vanos), chains, sprockets, tensioners, burnt out valves and valve seats).

 

Sorry but I believe the multiair unit would come under the definition "variable camshaft timing units" so I suspect you will be told the warranty excludes it.

 

Thank you I am gutted. How much should this cost? I have been quoted £1200 plus vat.

 

The unit is £1100 or so from Alfa, maybe 1.5h labor

 

sorry for butting in but on this topic of the MA filter - is it also fitted on a Non MA engine.
Mine is a 1.4 tb: 198A4000 / 940FXA1A engine.
Thanks

The MultiAir Micro Filter is only fitted to the MA units.

 

I got very variable prices. The cheapest I had, some years ago, was from AlfaWorkshop at Royston. In 2018 their price was significantly less at £820 than other quotes I had which ranged up to, from memory, about £1200.
Currently they are charging £1266.62 including VAT. See the bottom of this page Fixed Price Servicing For The Alfa Giulietta. (alfaworkshop.co.uk)
Just dug out the old invoice. As well as the unit there are a couple of gaskets and the micro filter. Then the oil is changed and that needs the normal oil filter and the sump washer. The billed labour was 2.18 hours.

This was showing as £1017 or something a week ago as I'm currently looking into getting mine changed, so it's only recently been updated. I think I'll just trade mine in and be done with it. Too many other niggly things need doing to it to justify that outlay.

 

Part is £750 including VAT from Alfa Shop. Then a couple of cheap parts to complete the job.
