Every 5 to 10 days I get the ENGINE STSTEM FAULT message for a second just as the engine starts on the first start of the day. It does not come on at any other time.

The FF runs and starts perfectly.

Any ideas why I am getting this occasional message?

Thanks in advance...

It just likes to worry you



Sorry, couldn't help it

How about you get any codes read and take things from there

Thanks Dingg1

Yes, it really enjoys worrying me!!!

I’ll get the codes read, thanks

Defo get the codes read with a decent diagnostic.... Gone to a good home: 2011 4.4 TDV8 Vogue SE Buckingham Blue with Ivory and clear glass = "Rory"
2025MY Defender D350 90 in Silicon Silver on coils
1974 Series 3 Lightweight = "Millie"
Many, many other Landies over the years

Read codes with iCarsoft reader:

No faults found relating to engine.

Noted the following readings with engine running at idle:

Boost pressure actuator Bank 1 - 0.76%
Commanded boost actuator control Bank 1 - 76.47%
Commanded boost actuator control Bank 2 - 76.08%
Swirl valve actuator 95%

Does this all look ok?

Thanks....

Thanks Stan, I’ll have a read through

I don’t understand why no fault is showing up on the reader given that the car showed ENGINE SYSTEM FAULT this morning?

Maybe I’m not using the iCarsoft properly....

Is this likely to be caused by a split in a top intercooler hose?

I know one of them has been replaced.

thats one of the first things i would check , underneath the hoses as well. ... - .- -.

Thanks again Stan, a job for today

Both top hoses removed, cleaned and checked….both in perfect condition.

No DTC on reader.

Last ENGINE SYSTEM FAULT message was on Thursday morning on first start, nothing since. Vehicle running perfectly.

Could it be actuator/s needing lubricated?

because its an intermittent fault it could be it sticking now and again... ... - .- -.

Thanks Stan, I’ll get the actuators checked/lubricated and go from there…..

Still can’t understand why no DTC has been logged and reported on the reader

I think what is described here is the occassional, random and very momentary popping up of the 'Engine System Fault' message which occurs as the car is turning over but actually before it has actually started. No other accompanying warning lights. Mine does this perhaps every 2-3 weeks. It started after the starter motor was replaced. As it happens when the engine isn't actually running I haven't followed it up yet. The car continues to run perfectly. I am curious as to what it might be however!

Thanks zeb. Yes the situation is exactly as you describe. I have had battery drain issues recently resulting in a replacement battery and a new alternator both which were not required as the drain was finally traced to fuse 49! The ENGINE SYSTEM FAULT message started at this time- I put it down to a low battery but now that the issue has been resolved the message is still randomly appearing!

How long has yours been doing this for?
