Hi,
New member, thanks for accepting me and my tale of woe.
I have a 2015 1.6 Diesel Focus estate.
My car made a 'whee' noise, warning lights came on and I came to a halt whilst doing around 70mph (naturally) down the motorway one night.
The AA diagnosed a cam belt failure and recovered me.
I looked over the car the next day  - no coolant so I poured some in but it came straight out underneath the engine.
A local garage took it in and confirmed the cambelt was stripped plus the water pump had failed.
They replaced the cam belt and the water pump plus the damaged rocker shaft etc.
The car is now running and sounds OK.
I have a warning light (amber engine outline) and a srvice required that came on initially when the cam belt failed.
The garage have now replaced the MAF sensor but the light is still on.
I bought a code reader which says 
P2279:00-E4 Intake Air System Leak Bank 1
P1102:21-E4 Mass Air flow in range but lower than expected.
Subsequently the car started leaking coolant again which the garage diagnosed as a thermostat problem and replaced.
I don't understand why all these problems happened simultaneously and are ongoing.
What is the connection if any between the fault codes now and the cam belt failing.
Any help much appreciated as the car has now cost £2,000 and is still not fixed.
Many thanks

 

To me, those codes (and "we" only really rate Forscan to get all of the codes) imply an air leak somewhere (after turbo)

Therefore, you may not have a full list of the codes.

This could be due to the work done and needs checking.

Unless, as usual, someone else can go straight to the issue...

Many thanks for responding.
Everything including this error happened at the same time or possibly warning fractionally before the timing belt failed. It's not related to the work done.
I sort of think it's somehow related to the initial failure - I can't see how that provoked what appears to be an air leak.
Wish I'd known about Forscan - had a look and it appears to be a USB adapter plus Windows software which I'd much prefer.

Are you a betting man ? 🤔

Cam belt failure causes a massive amount of damage to the engine, in many cases it's just not even worth trying to repair.

Since a repair has been attempted it will have involved a total strip down of the top end of the engine, and therefore the work often introduces problems that were not there before.

The only sensible thing to do now is to use FORScan and get the full Ford specific DTC's so that some in depth diagnostics can be done.

On the work done cause - I'll put money on that, error was there at cambelt failure (light on) although now I have doubts as the light may have been on for a different error. OK you win the beer🤔
I have found a couple of posts that also had the errors along with cambelt failure at the same time. One seemed to be related to timing in some way, the other, no cause as yet.
I have to come clean, it's friend of mine. He's 75 with little money. Initially he went to a couple of garages who told him to scrap it as did I. It's worth at best £2.5K and he's nearly spent that and it's not fixed. I was amazed the garage got away with just replacing the rocker assy. along with cambelt and water pump. They didn't remove the head for inspection. I bought the code reader because he couldn't tell me what the garage was telling him. 
I think the car is a lost cause but he's sunk nigh on £2K into his clapped out banger. 
Is the Forscan only applicable to Fords or is it generic.

You got me thinking, error came with the belt failure but of course, I didn't read the codes so they may be different now and as you say, somehow related to the work. The only thing I can say with certainty is that the car didn't have errors prior to the event.
Might look at the Forscan if the adapter isn't too much. Thanks for the advice.

Get FORScan, and a vLinker FS cable.

Use it to clear all DTC's and then see which codes come back.

Rocker assy?  In the first post you mentioned camshaft.  Was that not replaced?  The shafts on these are known for slipping cam lobes when the belt fails.  If it wasn't replaced, it's likely one or more of the inlet lobes are slightly out of time now.

No, Tom. He actually said "rocker shaft".

Fair point, but what else could that mean other than camshaft? 🤔

Hi Tom,
No, I don't think the camshaft was replaced. I'm a bit old school and more familiar with OHV. As I understand it, the camshaft in this engine doesn't directly act on the valves but rather by some sort of rocker assy. so I'm using terminology from engines I'm more familiar with (apologies). I had assumed the camshaft acted directly but apparently not in this case hence rocker arms which were replaced.
What you have just said makes total sense ie lobes slipping. I'd never considered that possibility but had been wondering what could have affected timing. How are the lobes located - interference fit, sweated on?
I'll have a look at the invoices and see if there's a mention, don't recollect seeing one.

Induction heating and pressed on. Once fitted they are never intended to move, but they do when the cam belt snaps and they get hit with the force af a couple of tons.

Just googled, yes, and they're hollow for lightness.
How things have moved on.
I'll post here once I've followed it up.
Many thanks

Indeed they have, it seems that vehicles have electric start these days and the old hand crank has been done away with !! 🤣

Well I interpreted "rocker shaft" as meaning the shaft that carries the rocker arms.

This is one of those situations where I've forgotten my own experience and used that as a baseline for everyone else's understanding.  This engine does only use one shaft at the top end, the rocker arms sit underneath it, they are not carried by a second shaft.  So the camshaft could reasonably be called a rocker shaft as well, but there aren't any other parts that could be named in that way.  I do realise that confusion was caused by own complacency now though.  Must do better in future!

Fair enough, Tom. Your description rang a bell that I'd seen that arrangement somewhere and I found it in the Haynes for our old Mk3 which includes a description of the 1.6 litre DV turbo-diesel. So your comments are now completely understandable.

The photos in the Haynes are awful quality but just about good enough to see the principle. Back in the day Haynes would have had nice line drawings. Their modern manuals are really cr@p.

Pulled the trigger on this item.
Saw the garage yesterday - they reckon camshaft is solid.
They are now saying it's something to do with the DPF.
They also say the rocker arms are designed to fail to save the engine when the cambelt fails.
I'll report once I've used the software you recommend.

It isn't.
It's nothing to do with the DPF.
The rocker arms are designed to fail first - but on this engine they don't.  (Been caught out by this myself.)

Must have been a specially made "anti-start" DPF just for that car 🤣

Hi,

More digging - car was sold as an 1.6 Titanium but the sticker on the door frame shows as a 1.5 Style.
Apologies for the incorrect info
Does it still have the hollow cam. What is the identifying code for this engine or how do I find it from the VIN code>
Many thanks
