My VRS is already mapped and have no idea if it has an EGR delete.

What does it do exactly?

You'll have a piece of metal pipe in place of an EGR valve (which also houses the ASV -anti shudder valve).

When you do this the ECU knows and records a fault and lights up the engine management light. It can be mapped out on ASZ engines but not BLT.

How would you know if you have a BLT enginer and not an ASZ? Does it matter the car I have has already been remapped?

year of car, I think the BLT engines were fitted around late 2005.

Exhaust gas cooler fitted on BLT engines.

Engine code stated on V5

So I probably have ASZ engine

The EGR has to be mapped out when it's remapped. Generic remaps wouldn't have the EGR mapped out. You'd have to request it to be deleted at time of mapping.

So id have to go and have the car remapped again

it depends who mapped your car to begin with.

do you have any idea who mapped it?

No and the previous owner doesn't either

You could also try unplugging it to see if it's already been mapped out.

A lot of tuners tend to modify the expected airflow map (EGR map) to close off the EGR to promote a faster spool-up, helps keep the air intake cleaner etc etc, as already suggested, disconnect the vac hose to the EGR and see what happens. If an EML comes on the software will need tweaking. This can be done to an existing remap if you go to the right person, a full remap is definitely NOT needed.

What lead do I need to un-plug

There is a small black hose going into the ufo looking thing and another lower down.

Just had a Shark map and they turned off the egr in the software as requested... I have a 54 plate BLT so it can be done....

Are you sure you have a blt, they didnt come in till really late 2005. I have a 55 with an asz

Checking on the V5..

Not sure is it will say on the v5. Check the cam cover under the engine cover it will be the first three letters above the bar code.

Thanks for that Joe, it is a ASZ.. and on the upside the Allard pipe will go straight on...

Apologies all, I'm still struggling to understand this and am concerned as I have an EGR issue at the mo!

It's going in the garage on Monday, think they're going to clean it. If they replace it, will my Awesome GTI remap be affected? Would you recommend anything to pass onto the garage?

Sorry kevin that I've gone off the subject slightly!

Kevins car is an ASZ and to my knowledge doesn't have an EGR delete.

So is there absolutely no way of turning off the engine light on a BLT engine thats been remapped with an EGR delete?

Both Shark and Jabba have maps that can turn off the light on BLT engines.

Cheers! Do you have to do the EGR delete when you remap it or can you remap the car without the EGR delete? Sorry if these are stupid questions but im new to vRS ownership! lol

No you can leave the EGR on if you want to.
