I’ve got a mk2.5 tdci and I was just going to the shops and the engine malfunction light came on and started beeping. Oh my short drive home from the shops it didn’t come on again and seemed to drive fine. Are there any common faults that cause this but aren’t serious? Or does it mean something bad?

Yes, classic instrument cluster cracked solder joints due to the use of lead-free solder. There are a number of companies that can repair and test for around £90 if you aren't confident about resoldering yourself.

I posted this topic about when it happened to mine. There are many others if you do a search.

Thanks. So do I need to run a diagnostic still though in case it is an engine fault? Or will an engine fault say something else? Don’t want to assume it’s just the dash if I do have an engine issue lol?

If you use FORScan to check for DTC's then if the problem is the instrument cluster you will have lots of codes beginning 'Uxxxxxx' and faults list as 'Lost communication with ............'

Ah ok thanks. Shall I just wait and see if the malfunction error keeps coming up before I take to garage to read code?

Also I wonder if it’s just my glow plugs? As twice since the message it’s taken a bit longer to start than it ever has

No need to take it to a garage you can read the codes yourself.

Does forscan show you when the car is due a regen/ let you force a regen etc? I’d find that useful by itself 

Yes. It does probably 90% of the functions that a Ford dealer can do.

Used it myself just after Christmas on my daughters Kuga:

Well good news (I think).

Finally got the new DPF sensor today and fitted it, which took only about 20 minutes. I cleared the DTC's and reset the DPF learnt values. Then off for a half hour drive on the motorway at between 60 and 70mph.

Took a couple of photos of the live data (ones a bit out of focus 😧). The car seems happy 🎉 and no EML or warning bing-bongs. 

 

If it is the common problem and you have U error codes then it can let you down at very inconvenient times which can be when you are actually driving along , it will say engine malfunction and the engine drops to idle speed. Which can be dangerous depending where you are. What engine size do you have?

It’s not done it since that one time on Sunday. It’s a 1.6 tdci. Is there any other common things that can trigger the engine malfunction as a one off?

never tried to count them but probably around about 10,000 or more issues can trigger the EML

Use FORScan and get the DTC's

Did you order yours from that site? I ordered on Tuesday but comes from China so will probably take weeks 

I bought mine from Amazon when it was on offer. Many on here have bought from that site and normally get it in 7 to 10 days.

If it’s coming from china I hope you don’t get caught for import duty, apart from the cost, it delays it also. It seems a bit of a lottery on whether or not you have to pay. 

How do you check on for scan when a dpf was last done or when one is due? I can only see guides on how to do a static regen etc but not to show when one is due. Also, are stating regens ok to do?

The current state of the DPF is what you really need to know. When it was or will be are variables.

Forscan is free. You have to earn the know how in order to use it. Most of it will become clear with an evening's research.

That info isn't available for the Mk2.5 Focus unfortunately.  (VAG DPF app is good for that on VW/Audi group stuff).

Static regens are safe enough but unlikely to be necessary on a cDPF.  If you've come across my YouTube vid on Forscan static regen for the Mk2.5, that was on the older Eolys type DPF.

You mentioned glowplugs earlier.  On the 1.6 TDCI, their failure usually shows the 'Engine Malfunction' message on the dash, but not the engine light.  After it's happened once, usually it'll happen again within the next few days.  Other common triggers on the 1.6 TDCI would be EGR or underboost from a split/cracked boost pipe.

The engine malfunction hasn’t come on since it did it last Sunday. Hoping forscan will able to let me know what caused that but I’m sure there will be loads of codes as I’ve not done it before. Also I think my car did a regen the day after the engine malfunction as my fan was on when I got to work in the morning and I had thought my engine sound was louder than normal. I took the motorway home and tried keeping revs high til I got home and engine sound is now normal again so guess it was a regen?
So do cDPF just not need regens as often?

cDPF's regen a bit more often, but it's a much more effective system.  They take less time to complete each regen, will work at slower speeds, and do a better job of clearing out the soot.  Even if you fail 3 or 4 in a row, it'll still clearout at the next one.  Where the old Eolys system would just keep compounding the soot, only burning a bit here & there, until it blocked the DPF.

Could well have been a regen. The best thing IMO when using Forscan on a car for the first time is to consider the value of stored codes. Consider this: none at all! You want to know the current state, not what happened before. It is very unlikely to help. Clear the lot, go for a run and scan again. If there are no DTCs, put the kit away and pour yourself a beer. If there are still problems then at least you won't be confused by irrelevant information.

Yeah I’ll clear the codes, just wanted to know what caused the engine error last weekend

Probably a DPF needing a regen as it appears to have done one and the MIL has been extinguished.

It didn’t come back on again though, came on as I was about to park at shops, never came back on way home or since. Never come on before for regens either?
