A couple of weeks ago going uphill the power (so good with the turbo) went pretty completely. I managed to limp up to the house (500 meters) in first. I switched the engine off. Re-started the car and it was ok, the power back in the engine.

I then duly forgot that it had occurred!

Last Thursday it got lovely big premium service and new front brakes and the car has been running really sweetly. After 250 miles I have been motoring up a steep and long hill today and the power went again, especially concerning in 2nd gear. It was like switching on the eco mode but worse. As it happened I was collecting a friend from a garage a few miles on, switched off the engine on arrival, switched it on and once again the turbo is firing ok and we drove back up hill and down dale flawlessly. Phew.

However, although I am no engineer this is a symptom of a problem, I suspect with the turbo or the mapping or something, and I will contact my Fiat garage in west Wales to discuss but wondered if there is any wisdom among fellow forum members that might illuminate! I would be grateful for any suggestions!

There's lots of, I'm sure, good advice on this threads re turbos, but... I would also consider whether the uni-air module is mis-behaving. My experience with a 50k miles TA was as you describe, power loss, feeling of running on one cylinder etc. My specialist (not dealership) garage in the end had to throw their collective hands in the air and apologised taking it to a dealership for the diagnosis.

The uni-air module provides the variable valve timing that gets this engine buzzing and effectively producing 100+ horses per litre which back in the day was every mini tuners holy grail! The module bolts onto the head and uses the engine oil to vary valve timing and lift hydraulically; thus making oil changes and grades, and indeed levels, absolutely critical.

A new unit was in the order of 800GBP fitted

There's quite a good supplier's technical briefing linked elsewhere on this forum or search for INA variable valve timing or similar.

Good luck

The sellers are very friendly and helpful too. In addition you can access a forum with further useful info.

MES could tyell you a lot and you can watch sensor readings live and graphed for you if connected when you drive the car.

Bought my daughter a Panda recently and it saved me a huge sum when I added a new remote key to the system. This was easy to do and took seconds. I usually take the kit with me if I am going away. It is amazing how things settle down when the little beast knows you have it cornered!!
......

Wow!

Giving me major pause for thought!

Thanks for this. As it happens i had just limped into Carmarthen this afternoon - the first time the car has lodt power since my posting - and i saw your message. Gulp!!

I managed to get to Cardigan and the car is booked for an inspection on Friday afternoon. so I feel well-armed with info about possibilities now and (gulp again!) forewarned about possible costs!

Will keep you updated....

Pete

Re: Panda 4x4 TA Cross, power issue!

Fingers crossed for a rubber hose or the like...

Assume the oil level is ok? Not the easiest dip stick to read, but use a clean piece of tissue and lay the business end of the stick on it immediately on removal - tissue absorbs oil indicating level. If you can see the oil because its black; change it pretty damn quick as they say!

As I remarked in another thread, the dipstick was designed by a stylist who thought it was a good idea to match it to the colour of oil.

Sounds like you went into limp home. Could be anything to cause this so a diagnostic is needed.

Re: Panda 4x4 TA Cross, power issue!

Update: the Fiat diagnostic revealed nowt. Chatting with senior mechanic i mentioned that at the recent full service the spark plugs had been changed. The car has only done another 2,000 miles since but they put two new plugs in as i requested...and the car seems to run well.

I dont really think it is the plugs...or can it be? The other change is that I have topped up twice now with very expensive Shell Premium Unleaded....who knows?

I expect the car to play up again soon, sadly.

I guess if there was a uni-air module fault it would show up on the diagnostic? My recent diagnostic revealed nothing though...

The original specialist (Fiat tech but not main agent) could not get the diagnosis with their non-fiat equipment, the main agent diagnostics found it.

Was the oil level OK?

Let's hope its a passing phase, I'll not speculate about stuff beyond my actual experiences.
