Did my EGR delete!

Man up you big baby.

finnneeee I will

Preenster drop Darkside Developments a line in the UK, it seems the Dieselgeek one is very limited in Euro fitment, being very USA specific.

Can you give me the engine code from the Caddy manual?

Ok will do. I'd obviously rather get it thru you though, dude. Happy for you to contact them if you want the business.

Engine # is BLS according to my rego papers (had them handy).

is your engine code AXR??

no real HP increase, it just feels more linear again, and smooth. I like it!

Getting rid of the EGR flap makes it a much smoother car to drive!

Nice! That's what i like to hear!

sure does! Big fan of the new driving experience

however my only gripe is by getting rid of the flap, shut off is a lumpy affair, scared the crap out of me when I first turned it off, but then I worked it out and it was all ok

Good to know before I do it.

was it tricky getting the egr motor out?

i might have to do this.

nope. The whole thing took about 20mins.

Also a quick note. When you do the EGR delete, blank it off from the exhaust manifold, You can blank it from three different places along the EGR itself. I blanked it from the top and the flex joint on my EGR pipe snapped

There are two coolant hoses that connect to the cooler, when you take the cooler off you obviously have to join them so the coolant continues to circulate. To do this, locate the hose that connected to the EGR from a T-Piece. Take that off and place the elbow hose that connected to the EGR cooler and connect that to the T-Piece. Looks OEM and it works.

While I was there I cleaned out my intake. Christ that was a messy job!

ive often thought about doing this with my t5, but too nervous. heard stories like it can increase temp and decrease life. does it make any difference to your polo?

EGT should not increase with an EGR delete as replacing the hot recirculated unburnt fuel with oxygen should help the fuel burn more efficiently and lower the intake temp

It also stops build up on the turbo vanes reducing the chances of them sticking and causing over boost

Worth while modification to improve the longevity

ive often thought my egr valve is stuffed, but dont know how to check apart from changing it. if i block off egr, then valve is still there and if its playing up then i may not achieve anything. im wondering if i can replace entire egr valve case with a peice of hollow pipe the same size, and blank off pipe from exhaust?

EGR is there to lower combustion temps. It's all about controlling NOX, and lowering combustion temp by addition of exhaust lowers NOX. More O2, faster flame front, higher temps, more NOX. The reality for a normal car is that you are right, and you don't see any major rise in EGT's, but if you really look into it, that's the theory. In a gasser EGR is about reburning unburnt fuel, in a diesel it's about controlling combustion temps.

Absolutley agree that more O2 from deleting EGR equals less soot, and that's a good thing, especially with a DPF.

In the 1.9 pre DPF I believe that is so.
