Re: 2016 Panda 4x4 hesitation/surging/running issues

Fiat customer service called today to say that as far as themselves and the dealer are concerned, they've checked absolutely everything, and there's nothing wrong with the vehicle.

They've now suggested that my only course of action is to try a different dealer.

I hate intermittent faults!

Re: 2016 Panda 4x4 hesitation/surging/running issues

I'm booked in with another local dealer in 2 weeks. Maybe it just needs a fresh set of eyes.

Fingers crossed for you!

My one is still playing about occasionally, but I can't really see anything with the scanner tool, nor come up with a routine that brings the fault on. No point taking it back to the dealer because it is clear that they won't do much unless they can unearth a clue.

As this is becoming increasingly frustrating, I might be tempted to sell up and move on to another car and just forget all about it. It's a shame, because she's a good motor when running right even though the rear passenger door can't now be opened from the inside!

Thanks mate. Hopefully, if I can get it sorted, it may also help you out.

I considered getting rid of mine a few weeks ago, but the going rate for the car I paid 15k for just over a year ago is around 9.5k. Unfortunately, that wouldn't cover the finance, and I'm not willing to lose money on it.

I hope to get it working properly. I've spent way too much money chopping and changing cars over the years, but I've had enough of that now, and this one was supposed to be a car I could keep for a good many years.

I was just googling for a good picture of the position of the EGR when the alert came in for your post. I'm thinking of taking it off myself and checking it over. Don't really want to as I'm definitely no mechanic, but I really need to get to the bottom of this.

This morning I tried revving the engine a little before driving away. The problem still occurred the first time through the rev range. Whatever it is doesn't seem to right itself until the engine has been under load.

Sorry to hear you're still having problems with the door. I'm guessing it's something I'll get to experience at some point as this has been a fairly unlucky car.

Re: 2016 Panda 4x4 hesitation/surging/running issues

Just looking around and came across Celtic Tuning. They say they can remove the EGR and remap the ECU to ignore the fact that it's missing. A remap may even smooth out some of the kinks in the rev range.

I wonder if it may be a route worth investigating. I've had 2WD cars remapped before, but not sure how good of an idea it is with a 4WD.

Maybe it's worth approaching a tuning company just to see if they have any insight on the issues I'm having.

Hi.
You say that with the Bluetooth dongle connected things improve. One quick test. Turn on the radio, select AM and tune it to 531khz. Then switch on the ignition either with or without the engine running, does the radio get very noisy? If so plug in your dongle and if the noise reduces you have an earthing problem. Now it could be anywhere, most likely at any of the ECU s or engine to body. This noise is electronic hash and if it effects the radio so badly it will be sending rubbish to the engine ECU. If you can't find the issue a decoupling capacitor to each of the ECU s supply "might" work.

Re: 2016 Panda 4x4 hesitation/surging/running issues

Thanks for the advice mate.

Ive just tried it, but the radio is noisy with and without the ignition on, and it's the exact same noise either way.

Worth a shot though!

Well at least this discounts earthing and possibly poor connections.
The reason I asked was a friend had similar problems on a 500. He also complained of rotten AM radio reception. I plugged in my dongle and both the radio and running issues stopped. Fault was the engine ECU earthing strap was broken.

Re: 2016 Panda 4x4 hesitation/surging/running issues

Just found another thread with some similar sounding issues which were again attributed to the EGR.

The "cough" they describe is particularly familiar.

https://www.fiatforum.com/croma-ii/1...multijets.html

I think it's time to insist the dealer checks the EGR out. If there's nothing wrong with it, then I'll pay the labour charge, but if there is, then they can get it sorted.

Re: 2016 Panda 4x4 hesitation/surging/running issues

I've just remembered something.

Years ago, I had a mondeo ST220 that had a flat spot/blip at the exact same part of the rev range every time. It was 2nd hand, so I decided to get a full service done with all filters, spark plugs, leads etc. Cost me a sizeable amount as I got all the genuine parts through ford.

When I got it back, the problem was still there. I just learned to live with it, and did so for months.

As it's a performance car, I'd been running it on 97ron from the day I got it. One day, the fuel station I always use had ran out of 97ron, so I put a tank of 95ron in. The blip instantly disappeared.

From that day on, I ran it on 95ron fuel, and the problem never reoccurred.

Maybe I'll try a few different fuels over the next few weeks. I currently run it on Esso fuel from the local Tesco station.

2016 Panda 4x4 hesitation/surging/running issues

Just back from the 2nd local dealer now.

Basically, as it's already been looked at by another dealer and deemed to be in perfect working order, they won't spend any time on it until we try another car to see if the issues are just a characteristic of the vehicle.

My feeling is that if it was a "characteristic", then it'd happen all the time rather than intermittently. They tell me that's not the case, but surely an intermittent fault is more of an anomaly than a characteristic.

They were able to feel the hiccup at 1500rpm, but I was unable to demonstrate the morning running issue as it only lasts a few minutes on a morning.

Unfortunately, the first dealer have been trying to source another car for me to try since February, so I don't see that happening any time soon.

2016 Panda 4x4 hesitation/surging/running issues

About 4 weeks ago, I decided to disconnect the MAF sensor on my car. I hadn't considered doing this in the past, as the dealer has already checked the MAF over, and on all the road tests, it was considered to be reading values in the correct range.

Long story short, disconnecting it transformed the car. I ran it for 3 weeks, and not once did I experience any stuttering in the mornings.

Not only that, but the car feels a whole lot different. It seems more willing to run at lower revs, and just feels a lot smoother when running around town.

The little hiccup at 1500rpm is still there, but I've found that I can reduce that to a barely noticeable level by using premium diesel.

I've also experienced what I believe to be a significant improvement in fuel economy. No matter how I've driven in the past, I have been unable to get more that 44mpg, and generally average 42.5-43. Over the last 800 miles with the MAF disconnected, I've averaged 48mpg. This is in no way connected to the premium diesel, as I've ran a few tanks through in the past and actually saw a decrease in fuel economy.

With all of this information in hand, I booked the car back into the dealers. I reconnected the MAF before I dropped it off, and as soon as it was connected again, the problems came back.

I've just spoke to the dealer, and they've fitted a new MAF. Hopefully this will fix the problem, but only time will tell. I'm picking it up tomorrow and will keep you all posted.

On a different subject, I'm happy that the dealers have also ordered me a part in to fix my noisy rear brakes under warranty. They were starting to get ridiculously loud!

Edit: My apologies......I've just re-read through this after posting and realised that it was in no way "long story short".
