Multijet Engine Managment Light

On my way home tonight in my 55 multijet Panda the dreaded engine managment light came on! I was pulling away quite hard from traffic lights onto a dual carriageway and when I hit about 3500rpm in 3rd the power cut for a second and the light came on. Since then it is driving fine with no noticable difference but the light is staying on. I don't normally rev it that hard so quite annoying!

I guess I had better take it in for diagnostics but does it sound bad?

Thanks

Re: Multijet Engine Managment Light

I've a 55 reg mulitjet too, with 120k on it. I bought one of those cheap code readers that revealed my fault as "EGR flow inadequate." The same fault was also 'pending.'

Nevertheless, it's running fine and returning over 60mpg. I reset the light and it came on again after only 30 miles.

In the long term, I plan to to remove and clean out the EGR but it's a big job and can wait a while. I'm not sure but I think a serious fault produces a flashing MIL, not just a steady one.

Re: Multijet Engine Managment Light

Malfunction indicator lamp (MIL) - if it's a one off fault then it'll clear after 3 good runs I believe (if like the Stilo).

Failing that then like already mentioned, time for a code reader.

May be worth looking at fiatecuscan.net

Diagnostics will show an EGR error with 99% certainty.

The EGR valve tends to get blocked with soot if the car is driven too gently and especially if you mostly do short trips in it.

Re: Multijet Engine Managment Light

It has gone out now after a few journeys! Does it make sense to give it a blast now and again to clear it out? I know people used to say that about diesels a few years back...?

Re: Multijet Engine Managment Light

I can't comment on the Panda, but with the VW/Mercedes vans that I also drive, there is a sticker which recommends running at higher engine speeds if the DPF light comes on.

No DPF on the Pandas thankfully

That still holds true. The EGR valve is a mechanical component which can get clogged with soot.

In your case, a good couple of blasts with plenty of throttle massaged the valve enough that it unclogged itself. In severe cases, disassembly and thorough cleaning or even complete replacement is required.

Its been a while since i visited and now i found a problem on my old car! I hope its not too serious, more than likely egr as its had a fairly easy life althoughit did have regular longer runs which probably kept it clear for us.

If you do boot it after a steady week have a look it the rear view mirror you will be able to see the soot being thrown out.

Re: Multijet Engine Managment Light

Had a couple of EGR problems with mine even doing a lot of fast mway work runs it clogs up tried cataclean fuel treatment which fixed the problem temporarily. Had first replaced under warranty second after contacting Fiat customer services they paid for the part & I the labour as its not easily accessed this was a coupe of hours as various pipework attaching needs cleaning too. Currently I am using fuel system cleaner a couple of times a year to ward off the next EGR problem. Basically EGRs are a pain and should have been designed as a service item.

Re: Multijet Engine Managment Light

Had exact same problems, boost pressure fault found by local gagrge. I changed the MAP sensor - no change. it was the turbo pressure valve linkage sticking, cleaned and checked when having the clutch done and totally fault free. It happened when I lent my car to sister in law who sat in traffic every morning from Eastleigh to Southampton and back again in the rush hour so no real turbo use.

Re: Multijet Engine Managment Light

I bought a lead from ebay and checked the error codes this weekend, I am getting...

P0238 - Air supply circuit anomaly
P0106 - Atmospheric/turbo pressures feasibility

Anyone in the know have an idea of what the combination of these two could mean...?

Thanks

Re: Multijet Engine Managment Light

Finally going to try and get this sorted this week. Afterwards is it advisable to gun the engine now and again to try and keep linkage free? What is safe to do? Should I thrash it down the motorway in 3rd for a mile or so or just drive it hard now and again?

Re: Multijet Engine Managment Light

From the two errors you posted in October, I'd say it's a MAP sensor gone out of calibration, and no amount of thrashing will fix that, only a new sensor. If you can read the live data, you'll be able to confirm easily (MAP will be reading significantly higher/lower than atmospheric with the engine not running).

Super. Will give that a go, thank you. Is it something I can replace myself and if not what sort of price should I be paying at an independent garage?

I guess having seen all the stuff about waste gates that I should still give the Panda a bit of a thrash here and there? I normally try to maximise MPG so it doesn't get much revs.
