Hey all, 

New time poster. 

The Fiesta (1.4 TDCI 2011) I use as a run around has had the Engine Management light on for a while now and on longer runs will go into limp mode. 

It's a really useful car to have around and keen to try and sort it out in a cost effective way if possible. 

The codes I've read are P0490 (EGR control circuit) and P132b (Turbo Boost Control) - there's a lot of information online as to the likely source on P132b suggesting cleaning the turbo might be a first step to resolution?

Wondering if anyone has any advice on the right things in which order. Or whether it's essentially something a professional should look at 😉 

Running around the city it's not really a massive issue but it's a big problem on longer trips. 

Given it's age and value, I'm happy to undertake some DIY maintenance. 

Side note - in the MOT they raised that there's an open recall, not sure if the EGR might be related to that or not (can only hope 😭)

Thanks in advance. 

Hi

You can check for outstanding recalls using your reg number on the .Gov website.  Can't remember any for the EGR on these though.  It's likely to be for the glow plug relay potentially catching fire or the rear suspension potentially falling off.

I think the 1.4 uses a wastegate turbo, so there's nothing to clean really.  It's the vanes on a VNT turbo that can get clogged with carbon and require cleaning.

P0490 is generally caused by the electronic side of the EGR valve failing.  Cleaning won't help that.  It'll need to be replaced.  And it needs to be the correct one, the Peugeot/Citroen EGR's are not the same as the Ford ones, despite the rest of the engine being virtually identical.  You could try a good used EGR valve with the same part number as your own to keep costs down.

Thanks for the advice @TomsFocus

I'm assuming the two codes are in some way related - P132b seems to be a more common fault than P0409 (I'm assuming if not directly related P0409 on the EGR is upstream from P132b on the Turbo at least - so you'd look to address that first). 

Having watched a few videos (annoyingly can't find a specific 2011 1.4 vid) changing the EGR is probably just about within my skillset / tools but might be pushing it a bit 🙂 (that said it's a older / low value car so less of a risk). 

I'd love to get to the personal satisfaction of resolving the issues but part of me just wonders if it's more sensible to ignore/clear, avoid long trips and see how long it lasts me. It's not really an issue on local trips, game over on duel carriageways / motorways though. 

 

 

Honestly it's just experience that's shown me the EGR code often causes limp mode on the 1.4 & 1.6 TDCI engines.  That's why I'd start with that one.  But there's no real reason you couldn't start with the boost fault first.

Chances are it'll be the boost solenoid that's failed to cause the P132b code.  But that's not as common on these as it is on the 1.0 EcoBoost.  

Changing the EGR valve isn't difficult on these.  I think you could probably manage it.   

@TomsFocus is there anywhere you'd recommend looking at in terms of steps / guides /  diagrams to reference for both jobs? There's a few examples to follow on youtube but frustratingly they seem to be for models either side of my 2011 1.4.

YouTube is my main recommendation now.

If you can find a good used Haynes manual cheap then they can be useful, but I don't think they're worth the £20+ for a new one.

I'll have a look on YouTube myself later to see if there's a suitable video for this.  Peugeot and Citroen 1.4 HDi is very similar so worth checking videos for those as well.

This is the layout 1.4 Zetec. as you say and from that I can gather the EGR is easier to get to on this model : ) 

Yeah, the EGR is just below the fuel filter at the back right of the engine.  I haven't been able to find a Mk7 Fiesta video either so I'm not sure quite how much access space there is on those specifically.  If it was mine, I'd remove the fuel filter housing for access, but try to leave all the fuel pipes connected so there's no need to bleed the fuel system afterwards.

@Brader1089, how are you getting on with it?  Have you resolved your P132B DTC?  If you're still to embark on this fiddly job, if you can get it on ramps just to remove the bottom bracket bolt, it's much easier than doing it from the top.  Reaching over the engine to remove the EGR and cooler with it on the ground it best after that.

Still chasing a resolution to this code myself.  Fitted a new EGR valve and cooler (£160+).   

The 11-year-old original just won't come apart.

Having replaced the EGR, still getting the P132B code.  Car has no outstanding recalls so I'm interested to hear how you're getting on.

Hey @Rickspark thanks for the above. I haven't had time to fully get a plan together yet. Interested that swapping it out hasn't solved it for you though. Above advice greatly appreciated in terms of access. 

I had a boost control fault also, for me it was the hose to the wastegate that was faulty.

Cut off a piece and put it back on.

Hi all, through July, the following DTCs triggered with increasing frequency on this 2013, Mk7.5, 1.6 Diesel Fiesta Econetic - PCM P0403:13-64, PB132:22-6C, P2562:77-E4.

As each day passes, I'm increasingly confident this is now resolved.  The problem: Leaking rear silencer.  (Pretty basic stuff eh!??  Just did not expect this would have this level of impact. )

Reflecting, the old leaky silencer was obviously impacting on various sensor readings and causing the listed DTCs and limp mode to trigger.

Hope this helps someone. Good luck with yours @Brader1089.

Hi all, the idea that the silencer fixed the issue turned out to be nonsense - the engine warning light showed its face again last week.  

I have now replaced the Wastegate Actuator Position Sensor.  A logical cause of the DTC codes - P132B:22-6C and   P256 - the ECU not receiving the correct signals from other sensors because of the Wastegate not being in the correct position.  Posting in the hope it might help someone else.

Initially, I replaced the entire Wastegate Actuator which includes the sensor.  I set the actuator rod to match the length of the actuator being removed.  The car performed as normal.  I asked a turbo specialist about the need to calibrate the Wastegate Actuator and he explained that this is not necessary on these cars as the ECU is effectively doing this in real time.  So, not calibration of the wastegate actuator required.

I hope this is of some use to you.
