Nice vid, but I'd recommend having the EGR mapped out on these engines. They tend to cause problems continually even if the car seems to behaving okay with no codes or other obvious issues present. The problem is that they are often open more than they should be which causes the engine to run a tad rough and underpowered, but hardly noticeable, this is then compounded by the fact the ECU tries to compensate by delivering more fuel, which in turn leads to a faster build up of deposits in the inlet manifold etc. Eventually the deposits can become so heavy that they prevent the swirl flaps inside the manifold from being able to function properly, they can stick or even worse snap, this can obviously cause serious engine damage, usually because a piece of the broken flap gets lodged under the inlet valve holding it open, which results in the piston striking it, the outcome from this is usually not good at all. Also worth doing a leak off test on injectors once and a while, these units are prone to the seats wearing out prematurely. It's true a leak off test can only detect excessive flow through the spill off side of the injector and not leakage from the tip, but it's quite likely a faulty injector will likely leak both sides anyway, so it's a good idea to keep an eye on them.
I have a 1.6 65 plate insignia and I have this dpf fault. Was thinking of blanking it but heard some horror stories of the engine blowing up because of it
@@powerhouse2669 Unfortunately you can't just blank it off on these more modern systems, the ECU will recognise that there's a lack of gas flow through the EGR system and will illuminate the EML light on the dash. It has to be mapped out by someone competent, but beware many aren't, and this can be the reason people run into trouble when having this procedure carried out. Another option is to fit a restrictor plate, this is basically the same as a blanking plate but it has a hole drilled in it that only allows enough gas through to prevent triggering of the EML. It's not perfect but it does considerably extend the time scale before issues are encountered by the build up of carbon from the EGR system.
Excellent advice. If I have it mapped out, I will obviously need a blacking plate but, which pipe am I blanking? Also, would it pass the emission test? Thumbs up bud!
@@catxls1835 The benefit of having it mapped out is that you don't need the blanking plate, as the valve will never be commanded open again anyway. Blanking plates were simply a cheap fix for the older style EGR systems without the need to use a mapping service. Regarding emissions. If the mapping has been carried out by a competent technician then there should be no problems getting the car through its annual test, but beware if its done badly there can be issues with higher emissions and increased fuel consumption. Best to seek advice or recommendations on a suitable online forum for your vehicle, ask if anyone has had a good experience with any local tuners in your area.
Close valve and unplug electric connector, had egr probs several times, running like this last 6 months no issue, won't pass an MOT as engine check light on but runs great, will have to clean again and plug in for next mot
Wish I had found this video earlier lol. I also have 2011 insignia cdti and mine also had to be towed. It refused to start after being washed in an automatic car wash. Cost 500 euro to replace the valve, maybe I could have cleaned it instead.
Thanks for the video.. do you know what is the name of that gasket under the valve? Because my valve is stuck on gasket and it is not possible to remove without damaging gasket.
Help in short time too clean, the problem of thats happend its the owner drive to short distanse , the exhaust temprature its high enogh , and engine its never in the worktemprature , cars with ,EGR, Catalytic cleaner, DPF , its made fore longer driving distanse in higer speed
Hi, It's a 2011, take a good test drive in it, the seats are so uncomfy on the back, I think the newer one's are the same, apart from that not a bad car.

@@Altair885 These cars are crap anyway! Unreliable money pit cars. That's why Insignia costs 50% of the same age VW.
Excellent video! One where I can actually make sense of what's where
Glad it help, that's what it's all about. :)

I think its just called the ERG valve gasket
That was a very informative video my friend!
Do you recommend disconnecting the battery to do this? have seen alot of people do but wondered if its necessary
Hi, I don't think you need to disconnect the battery
@carsbikes9961 thank you, your time and response are appreciated
Hi! My egr valve is very much stuck on the engine. Do you have any tips on how to get it loose??? I've been trying for hours now.
Could need a gentle tap with a soft hammer or similar and twist it, just make sure all the bolts are out.

Superb!
What year of insignia are like this? Looking to buy 2017 1.6

great video
My 2010 insignia is smoking badly,white smoke 🤦♂️
