Poorly running 4x4 TA

Bugger!
My 4x4 TA has started running rough.

It's a few days short of it's second birthday with just over 12k on it.

Yesterday, when pulling away from cold after about 150 yards it coughed, stuttered, clattered and shuddered.

Not a full misfire, it was definitely still firing both pots, it was more like the it lost most of it's power like it was retarded and sounded awful for a few seconds.

It seem to snap out of it as the revs rose and it drove ok the rest of the short trip.

Today, same trip, same place, it did it again, but this time did it again 10 minutes later and again after that.

When I eventually pulled up home, it didn't sound too happy, noisier/rougher somehow, but was pulled reasonably well without the flat spots.

Seems to do it when pulling away, I lift the clutch, apply some throttle and it struggles to build revs smoothly, looses power and sounds all clattery and shuddery.

There's no EML lite, but I'm starting to think it's got a problem with valve timings!

Re: Poorly running 4x4 TA

Just checked oil level and it's spot on as it always is, but it's now idling like this:
Tick a, tick a, tick a, tick a, tick a and so on.

Sounds like it's coming from the head/valve train and it makes my fillings arch!

Had a quick look around the web and on Alfaowners, the Multiair can fail if the wrong oil has been used and they go around 2k after it's been put in.
Mine was in for an service/oil change at the dealer 2k ago!

Re: Poorly running 4x4 TA

Yeah, easier said than done.
I guess I'll have to wait for a "slot" at the dealers.

I'm fuming, as I needed this one this weekend.
I've two other Pandas, but this is the only one with a towbar!

Re: Poorly running 4x4 TA

Looking at some Alfaowner threads, some owners report their Multiair system failing shorty after a service, 2 thousand seems to come up.
It's been suggested wrong oil is to blame and that some dealers aren't using the proper spec.

I can't say for certain what the dealer put in, but it was 2 thousands miles ago when mine was serviced.

I'll ring tomorrow morning and book it in, but I'm not to happy about driving it there as it sounds like cement mixer running on marbles!

Would running it in cause any damage if it was a fault with the Multiair system?

Re: Poorly running 4x4 TA

I wonder how your spark plugs are doing? Mine had almost cooked one of my plugs the earth fork was almost all but gone. It would hesitate etc under loaded acceleration. Might be worth a check.

Actually, the plugs have been mentioned a few times so yes, get out there and check them. If nothing else, it eliminates something but if you're lucky, it'll be a relatively cheap fix.

Question Re: Poorly running 4x4 TA

Hi All, I have had this as an intermittent problem from before the first service.
Mine is June 2014. Have taken to two dealers, who have both said NO FAULT FOUND. I have broken down in the outside lane of a fast duel Carriageway, this brought the EM light full on and the car refused to restart. After being recovered, about 3 hours later the car coughed into life and the EM light went out. Both dealers say no logged fault code!!. My dealer I purchased from states that them or Fiat have no knowledge of this issue. Oil levels and grades have been a point of blame, and I now understand that with a VVT engine holding only about 3.5 liters means that this is critical. Some comments are that overfilling somehow stresses the Camshaft sensor, and I understand their a several timing modes. I have seen a thread last week that replacing this has fixed the fault, but can no longer find it. I have been back to my dealer with whom I have a lot of confidence, but he is giving me a hard luck version that is, unless they have an EM fault code Fiat will not pay. A bit difficult for me about 100 miles from them. And I am told that any EM error is soon removed!. I have my own Diagnostic Kit so hopefully, I can capture it if it happens again.

Re: Poorly running 4x4 TA

It's booked in, but the soonest they can do is the 29th!

I'm furious, I'm going to miss a whole weekend of sport over Easter as I need the towbar!

Re: Poorly running 4x4 TA

Well after a few tentative trips around the block it's seems to run a lot better.
The clattery sound seems to have died off and it's as smooth as ever (so not very smooth).

It looks like it just needed burping!

Bad fuel? Condensation?

Could still be an intermittent fault so worth leaving it in anyway to get codes checked etc, also worth having a gander at the plugs.

Re: Poorly running 4x4 TA

That is exactly what I experienced for a while after I got the car to restart. Drove back home with everything crossed (240 miles) with no repeat.
