Egr blanking and map delete

[Csr dog]

Had my egr blank and map delete today, wow what a difference, no smoke, pulls from low revs and goes like stink

 

[lisknik]

Does it really make that much of a difference??

Remap next??

 

[Csr dog]

Huge difference as fresh air and not soot is now entering the engine

 

[conaero]

Is that on the 1.9JTDm yes, can you tell me more, costs, where to get it done???

 

[Csr dog]

I paid £150 inc the vat at autolusso but i had to pay an extra £60 as my map sensor was that clogged up it looked like a small piece of coal!

Yes mate 16v, mine is like a different car.

No, an EGR and MAP sensor clean do though.

 

[conaero]

Can you tell me where the MAP sensor is, do you mean MAF sensor?

 

[ALFA TUNER]

The MAP sensor is on the back of the inlet manifold,little black unit about 3-4cms long secured on the manifold with one screw(usually torx)

Just an ebay link so you can see what it looks like

Just reading this post, Mike is thinking of getting the DPF removed on his 2.4 159 with the remap as well of course. At the moment he has a partial blanking plate on the EGR which has improved smoothness and delivery.

Can anyone recommend a good garage to get the work done?

Mine is so much better though, smooth! Responsive and pulls so much better.

I work with some diesel fitters and they all say the egr blanking will eventually
Mess things up avoid at all costs.
I don't know much about engines I'm a coach builder but they all agree.

 

[ALFA TUNER]

Lol,ask them why.

 

[WTI]

I will tommorow

Because it allows the temps to drop too low at idle burning out glow plugs and gives an unclean burn and clogs the turbo and exhaust with soot. You also need the metered heated exhaust gas to bump up the inlet air temp at idle to prevent thermal shock in the cylinders. The real solution is to annually clean the EGR and MAP sensor and scrape out what you can from behind choke valve bolted to the inlet, that way the car will run as it should, plus every few years with your cambelt change it might be prudent to to remove the inlet manifold and clean it out properly too.

I thought it would now be a clean burn because it isnt recycling soot?

 

[Smaky]

Think, now that all this soot isn't going round to the inlet, where IS it going?

Also what are the 2 things required to burn diesel?

Out of the exhaust i would imagine.

The plate has come from main dealer and is a recognisedmanufactured part its not a total blanking plate so does allow some flow. In my opinion the diesels should have been fitted with these from new. We have done 5,000 in our 2.4 with the plate over the EGR and the car pulls like a train no soot. In fact its cleaner than ever, granted the car does motorway miles every day and we do run on shell optimax. The car starts better, no hesitation, pulls very well and generally seems happier.

 

[Smaky]

Ah so you have the 4 hole plate, that will still need the egr cleaning every so often.

Eventually, but first it ticks to the turbos turbine blades, imbalanding them and killing the bearing, blades and seals.
