A couple of months ago I started getting intermittent misfires, now it's constant.

I get a load of errors on starting the car - VDC Unavailable, Steering Corrector, Hill Holder and the engine is vibrating heavily.


Also getting quite a bit of smoke from the exhaust.

I only have basic diagnostic app on my phone which gives P0301 (Cylinder 1 Misfire) and P0300 (Random Misfire). I've switched coil packs around, but still always the same Cylinder 1 error.

I'm going to have to get it to a garage - nearest Alfa dealer is 25 miles away and no local specialists, but just hoping for a heads up on what it could be?

Battery is 5 months old, new plugs and filters and full oil change 6 weeks ago.

I really hope it isn't the case, but there have been occasional issues with engines failing.

It seems that when a spark plug is removed a large part of the end is missing.

It is either the cause of or a consequence of an engine failure and major damage is found to the pistons, head and valves.

However I would rule out more simple issues such as a failed coil pack first (Swap the pack from the missfiring cylinder with another and see if the missfire follows it to the other cylinder)

I had read that thread when searching... hopefully not that. The old plugs were OK when removed and there is no visible damage to the coil packs.

As per the title of my video, was wondering if it is likely to be MA failure.

I am not familiar wiuth the MA unit myself, but there should be information here.

The earlier units (such as yours) were the ones most prone to failure.

Had it to a local garage who did some diagnosis and have confirmed that there is no pressure in cylinder 1. Fairly sure it is MA failure now. There's an Alfa specialist about 20 miles away that have good reviews so going to try and get it in there soon to get sorted.

Just an update if anyone has the same symptoms - it was the MA unit. Fixed within 2 days by WAD in Wolverhampton (highly recommended if your Midlands based).

Did they repair or replace?
How much did they charge, if it isn't too nosy?
They replaced for £609. However, this was such a good price because they already had unit in stock that they bought at a much lower price than they are now.
