Egr delete

Hello everyone. Has anyone done an egr delete on theyr 1.9? I found these fellas on ebay who chip tune and sell ecus, immo off, just swap ecu and you get an instant remap. Not expensive either. A 115 bkv like mine goes up to 160 hp tops and in torques too, which is enough for a big ol bis, i just wanna pull a caravan properly tbh, not to go nurburgring.
Anyway, they can also offer egr delete at the same time, so im considering it. Im an mot inspector, so i dont worry about higher emissions (i understood is exactly the opposite). There are some cheap kits on ebay that can be fitted easily. Now i like my bus, i bought a properly recon turbo to bring it back to life and drives great, but never had a car with deleted egr. Will it cause any harm to components, any one heard of head haskets failing due to increased temps, blown turbos or serious stuff like that? Having 200 k miles, the egr valve is visibly tyred anyway, can see oil weeping through joints although the valve itself is not clogged. I could buy a new egr, offcourse, but i am more inclined towards a delete. Parts are cheap on these old cars, so not really a massive expense.
Any thoughts?

That's actually how I remapped mine with a postal map, but the Galaxy has a separate module for the immobiliser so I haven't lost that part, just be aware insurance companies do regular checks to see how a car was stolen so on the off-chance yours was nicked they may not pay out - fairly small chance but still something to consider. Yes, you'll stress the components more I noticed the oil temperature runs about 10*c hotter with the map but if everything else is in good condition (including your run-on pump) then it should be fine assuming the mapper knows what they are doing and its not excessive - 160 from the 115 IS excessive. The 115 goes to about 145/150 safely and whilst it CAN go more on something like a Golf, the Golf isn't carting around 1600 Kilos of weight.

I'd also be wary of any ECU mapper saying they can do an EGR delete on the 1.9, the EGR is non sensing on these engines, you could unplug it and drive forever more without an error code or MIL light. There isn't really anything to map out and you don't really need to do it on the 1.9 anyway since you can set the duty cycle to near zero within the software.

Hello Mirez, and thanks for the input. I dont have many important things to say on this forum, but ive red a good portion of it and i could count on the fact you'll be amongst first to jump with intel. Cheers to you for that.
I know the egr is not electronic on these. I know there is not much to program about it, i just considered either buying a new one or the delete. Like i said, just wanted to know from people who done it and drove it like this if are any major issues. Offcourse will stress components, but if you dont rag it like a morron goong on 7000 rpm, service it on time and be just a regular driver, should not cause issues, right?

Well a map works by bringing in the turbo earlier and running it an higher boost pressures as well as raising the fuel rate and advancing the throttle position sensor, that's why they are so effective on turbo engines. So even if you drive it exactly the same as you did before then you'll still be stressing those components more then you would be without it, but no its not going to do serious damage quickly. I still think 160 is too much from the 115 though!

Mines a 115 remapped to 145, which has done about 80K miles since and it's been solid with no reliability issues. As for the EGR, it's still on the original which is set to 1% duty cycle so it very rarely does anything. I doubt there is anything to gain by removing it but equally it's not going to do anything nasty by doing so and you will stop the manifold gumming up at least.
