Fl 2 Engine Failure

Sanbuild · Jun 4, 2023

Hi
I have a 2009 TD4 with 171K on the clock I was motorway driving and suddenly heard not a loud catastrophic banging but what I would say was a muffled noise from front followed by ignition lights.
Luckily managed to put out of gear and coast from 70mph onto a slip road where I spent next hour and half waiting for AA
Strangely they said they can't do emergency checks as it was a motorway but offered home, a garage or a service station where they could carry out their roadside checks. A year previously they diagnosed a crankshaft sensor at fault so I thought I would accept this offer so was dropped of at a motorway service area and waited another hour for the AA man with the van
He arrived did normal routine of checks including battery pack. Engine turned over but no ignition he then plugged in his laptop whole series of codes but he could not say if it was anything conclusive.
I had a new cambelt 3 years previously so thought maybe not but AA man would not guess, but offered to arrange for another truck to take me home as I feared the worst and as garage recons are 3 to 4k, thought would first try myself as local dependants have 4 to 5 week wait just to look.
So engine still cranks over but have drained battery twice. I originally thought cam belt again, had I bin ripped off previously with old belt and read up on taking the head off and a new valve set.
But got as far as stripping cam belt covers off and surprised to find the belt still intact.
So below is a read out of AA roadside print out, I think a few old red herrings mixed in. Does anyone have suggestions as to next step?
See below AA roadside report, bearing in mind there was a noise beforehand.
Report - -
Patrol found the following fault code/s:System : Engine control - 57Y / Diesel EDC 16CP39 Status

Any advice appreciated
Thanks

Can you do a video of it cranking over, so we can listen to it?
It looks like the throttle body valve is stuck closed, which would stop it running or starting.

Hi,
Thanks for your reply. I have attached a video I took a couple of weeks ago, it shows the engine turning over several times and although I have a battery boost on it in the video I’ve tried it again with a full battery…Same result.
Yesterday, I took the rocker cover off to investigate and, the chain is fully intact.
Cheers

I would use a scanner to delete the codes left on the ECU, then see what pops up during cranking, The difficulty at the moment is the plethora of codes generated and which ones are still relevant to the source fault.

PS. My FL2 had stripped several teeth on the cambelt without snapping.
To check , take the top cambelt cover off and mark a point on the belt,
then rotate the engine off the bottom pulley whilst looking for gaps where the teeth should be,..until you see your reference mark on the belt again. To be sure your timing belts 100 percent

Hi thanks for replying
I will try a new scan after reseting what I can delete at the weekend as I have some parts to replace first.
Also good point about the cambelt although they at first look OK I have not thought to check the whole belt for missing teeth only odd sections I noticed at the top cam.
Hopefully find something.

coltron1 · Jun 6, 2023

My FL2 was bought as a none runner, and during fault finding I initially diagnosed an intact belt too....weeks of starting attempts followed, until I decided on doing a cambelt change while the cars was on axle stands, ( to ensure the engine timing was correct) I've changed a few timing belts over the years but I'd never come across missing belt teeth before then.
This scenario may explain the noise you heard?

J_D · Jun 6, 2023

Can you check the cam timing for a slipped belt?
If you have an oscilloscope on the battery you can check for a rough evenness of the compression of the cylinders.

coltron1 · Jun 7, 2023

Hi jd.
Assuming the timing locking holes line up on the cam pulley and flywheel, ( remove starter motor for access), i would consider the engine is timed ok,

unfortunately that won't tell you if the injector pump camshaft drive-end has sheared though? I've come across threads showing pictures after the fuel injector pump, momentarily seizes due to internal swarf build up.

to determine that without removing the pump, Live pressure rail data while cranking might give an indication. e.g. zero mpa. is undesirable.

(Oscilloscope on the battery ...... interesting)

As above check the the throttle body for the plastic cogs may have stripped some teeth

If so you can purchase either a new throttle body or repair the one you have with this kit.

3

I glued and screwed mine has a belt & braces fix, well a spare i had not yet fitted it has mine seems ok.

4

screwed which was then ground flat,

Nice fix, especially the additional screws

I know from experience that glueing on its own eventually ends with the cog plate falling off during use. Even after following the instructions

Sanbuild · Jun 10, 2023

Thanks for the advice I will follow both this weekend. Below is a report I carried out with my basic OBD reader, so it seems to focus on both the Throttle Body and what I interpret as the fuel pump, so If anyone can advise on this that would be useful. So I will start with removing the throttle body as its the less costly. If I remove the fuel pump would a fault be obvious? Also when I removed the pressure rail I was expecting a lot of diesel but there was none?

Below is latest report I have after a basic reset and cranking:

That's a lot of fault codes...
Anything observed from live data?

Sanbuild · Jun 13, 2023

Yes agree too many fault codes to say but I will need to reassemble for another check.
I have checked cam belt teeth and also lined up crank and cam successfully with lock set so can rule out belt slip,. Also throttle body the flap operates mechanically and sounds good
I note high and low pressure fault on readout does this point to the pump if so is there a check?

Yes,
You can crack off an injector and look for diesel while cranking, but your OBD tool should indicate a poor pump without a spanner to anything.
Are you familiar to live data functions?

Nodge68 · Jun 13, 2023

Lots of codes aren't necessarily something to worry about. A weak battery and not allowing the system check to complete before allowing the engine to start will generate loads of codes.
I have a larger than standard battery, and always allow the system check to complete before starting, and I very few codes. It's always best to all the system check to complete before starting, so codes generated are relevant, not ghost codes.
Cracking the injectors isn't wise, as A the injector pipes are a tighten once design, so need replacing if released. B the pressure is enormous, and can easily spray high pressure fuel through the skin with fatal results.
If you want to check for fuel in the rail, lift a spill line from an injector, and fuel will emerge

In this case, I'd be looking for bad wiring, under the air filter is a classic harness damage point. The items effected may well be on the same fuse, so check all the fuses in the engine bay fuse box.

coltron1 · Jun 13, 2023

Safety tip acknowledged Nodge.

Sanbuild · Jun 13, 2023

Hi thanks for feedback I get the message about not mixing diesel with blood, insanely high pressures by any measure
I need to update my OBD reader as wasn't sure that live reading can be done whilst cranking
Also Nodge I will make the checks on spill line and trace the harness as advised.
Though it will have to wait until the week end now

coltron1 · Jun 14, 2023

All ECU fault codes deleted?

With live data, a user can monitor all available sensor information in real time, during cranking (even if the car doesn't start) and while running. .
Whatever new codes are generated during starting can be read and hopefully provide direction for fixing.
most (ebay budget) obd2 readers have the function, and provided a good battery is used while cranking, (otherwise you create more fault codes as the battery depletes). will provide values for the pressure rail.

Course you could pull the injector pump off and check the drive cam is in one piece, though you still need to establish that the pump is creating enough pressure for the injectors, The ECU needs the rail pressure to be above a certain value.

pwood999 · Jun 15, 2023

Surely one of these two must be a rogue fault ? +1 on check you actually have decent fuel rail pressure.

Definitely worth checking the sensor as well, as plenty of vehicles show exactly these two faults when the sensor or wiring is bad. No guarantees the ECU will actually trigger the injectors when these are present.

P0088 [0x0088]
Fuel rail/system pressure too high
Status: Pending fault present, Pending fault present during this driving cycle, Test conditions are met, Test is inhibited by other DTC, Test has not been completed, Validated and stored in non volatile memory, Validated fault present at time of request, Validated fault has been present during this drive cycle
----------------------------
P0087 [0x0087]
Fuel rail/system pressure too low
Status: Pending fault present, Pending fault present during this driving cycle, Test conditions are met, Test is inhibited by other DTC, Test has not been completed, Validated and stored in non volatile memory, Validated fault present at time of request, Validated fault has been present during this drive cycle

coltron1 · Jun 15, 2023

Fair point, can,t be both........... possibly neither. Low battery causes lots & lots of ECU mayhem, all those 12v devices trying to run on 11v (during cranking)..you can even watch the battery voltage drop with live data OBD2
