OK, here's my translation directly overtyping the Spanish, no Google. I find it really messes with my head if I try fixing Google's quirky phraseological guesswork. It's after ten and I'm starting to squint, so pardon the on-the-fly typos. I'm sure I'll find them all tomorrow.
--------------------------------
It's a long time since I disabled it, but today I took some photos to show you how you can do this. First we're going to take some key steps , know what it is, it's purpose, the pros and cons of disabling the EGR in our car.
- What is it? The EGR valve is a solenoid that, to reduce pollution, introduces part of the gas flow from the exhaust pipe to the inlet manifold, achieving a reburn and therefore cleaner outcome. It would be something like us breathing part of our CO2 with our O2, so that we breathe bad air. The EGR funcions at low revs, from idle to 2,200 RPM approx., from this point on it remains closed.
- What's its purpose? As I've said, its funcion is to have the vehicle pollute less, complying with EURO4 and EURO5 pollution laws.
- Pros of disabling: The car breathes better, shall have somewhat more torque down low, we shall notice that taking off on incline the car takes off better, above all if we hit a speed hump in 2nd gear and try lifting (hoon?) the car. Apart from this we prolong useful engine life, since the gas flows tend to become increasingly blocked over time and kilometres. It passes inspection 100%, in diesels exhaust opacity is measured and EGR has absolutely no bearing on this.
- Cons of disabling: It will reach operating temperature more slowly, the car pollutes somewhat more...
- How to disable it? That's where we're going...
Necessary materials:
- (Metal) sheet at least 0.5mm in thickness.
- Ratchet and socket wrench 10mm. and 13mm.
- Pressure(?) pliers.
Info:
- Time taken: 1:30h. Approx.
- Estimated price: 0€.
- Difficulty: Medium, we can't forget any component as we rebuild everything, we have to pay a lot of attention to what we're doing.
We begin:
1. The first step is to dismantle the engine cover and the inlet bell (manifold?), for that we dismantle the 2 screws of the cover and the 2 of the bell, the 4 are 10mm., once off, we pull upwards on the cover to free it from behind, and to remove the bell we pull upwards at the same time as out.
2. Following on, we should remove the pipe coming from the intercooler, for that first we remove the bracket, using the pressure pliers, and once free, pull on the tube carefully to extract it:
3. Remove the air meter, for this remove the 2 10mm screws. as seen in the image, once removed disconnect the sensor by pressing the clip, once removed, pull on the whole module and it's out: (CAUTION: Now we have the inlet collector exposed, don't let anything fall into it or we will blow the motor, I advise putting newspaper or something to avoid anything getting in... If it does DONT TURN ON THE ENGINE, try recovering whatever fell in with a magnet or something).
4. Now we have to remove the EGR pipe at the inlet of the collector, which is where we can plug the operation of the EGR without affecting the valve so that we won't get caught out, for that we take out the 2 screws that hold it, one of them is behind as seen in the image:
5. The other is on the front part, both are 13mm., what you see oily is that by not getting a good join it sweats a bit of oil fumes here, no big deal, it's simply a bit stained.
6. Once removed we have the join, as in the photo, take care that it does fall against the motor because we need to use it as a mould to create one the same.
7. Following on I show you what has to be done, we have to copy the sheet fully without the big hole in the middle, the 4 flanges are not necessary, copying the sheet with hole and screw holes is sufficient:
8. We assemble everything.
With that and "a piece of cake" we have the mod done, now to enjoy our new motor
.
P.S: I have my sheet available for whomever wants it they want to start making their own ahead of time and that way make the mod quicker, I'll probably pass it to Apejeje on the 22nd, when I make his sheet if you want to start asking
.
I hope this will help!!!
