As post header says our Panda Twinair(2012) has developed a misfire severe enough to bring on the triangle of doom,my local service garage has no idea where to start,any ideas or help?.
Thanks,Graham

Don't want to be doom monger but consider the Uniair module...
How many miles has it done, and has the servicing been kept up?
Hope its the plugs
The Uniair/Multiair unit is a mechanism the works between the cam and the intake valves to adjust the valves timings.
It uses solenoids to control oil within passageways that act as a fluid link between cam and valve.
It basically uses engine oil as a push rod on the valves.
Altering the pressure of the oil alters the link, thus altering the valve timings.
There have been reports of failures, not many but they are starting to grow.
It's relies on the correct spec and amount of engine oil as it's this that it picks up to act as a fluid link, so it's worth checking and topping up the oil if it's a little low.
There's also a small oil strainer within the system, they can get a bit dirty and it's worth a clean every 30,000 miles or so, and no they aren't part of the service schedule.

Very glad for you that it is the plugs.
As Goudrons says, the uniair module essentially does away with the inlet valve cam and allows ariable valve timing and opening to optimise engine performance (or more specifcally immissions I believe - the two don't go hand-in-hand!).
There's a very good link somewhere on this forum to the OEM suppliers data sheet for this module which sits on the top of the engine. Oil and oil spec is everything for the performance of this system; do not cut corners with cheap oil!
The symptoms of this unit failing are hesitancy, missing on one cylinder and associated engine warnings...
Sorry but has nothing to do with aircon...
Before you start thinking the worst, check your engine oil.
It's not easy with the TA, the dipstick is better than useless, but make sure it's up at or very near max.
Allow the oil to settle a while after driving before you check, say an hour or so.
If it's short on oil it can cause the Multiair to play up.
Just add a little at a time until it creeps up to the correct mark.
Anyone should be able to change the plugs for you.
There's nothing really tricky about it, with a few tools (10mm socket and a plug socket, see below) you could probably do it yourself.
The only fiddly parts are the air pipe to the turbo, it has a Clic R clip that can be a struggle to reclip again after (without the right tool).
You can bin it and fit a large jubilee clip though.
The plugs themselves require a thin walled plug socket to fit down the holes, they aren't expensive, Laser 3682 fits perfectly.
There are guides about that can help you with the job.
If after there's no difference, then think about getting someone to look at it.
What's wrong with the air con?
My worry is that your local garage to quote your own words "has no idea where to start". Its like going to your GP with a serious and complex brain issue, he'd be out of his depth and would refer you to a specialist.
If this is the garage you use for servicing then reading between the lines they are unaware even that the TA needs the correct oil, let's hope they haven't been using Duckhams Q20-50.
Graham, if your garage has parts supplier they can get this (Selenia branded by Petronas themselves). Total do a similar oil, so if still specified for use by Peugeot and Citroen dealers you can source from them. Also there's a Castrol Magnatec Ow 30 C2 developed for Honda. https://www.eurocarparts.com/ecp/p/...ngine-parts1/engine-oils/?521772801&1&cc5_249
