I was wondering if you guys have ordered egr delete kits. If so where did you get them from because I can't seem to find a site that has any. I have a 2003 VW Beetle TDI. Thanks for the help!

2004 pd tdi jetta overboost

My tdi is over boosting at 17.3 PSI for a dangerous number of seconds, also my duty cycle on the 011 log starts at 98% and quickly crashes to 5% . What on earth is happening to my tdi. I hear of clogged vanes or actuator rusted out. Also I just had an underboost code show up. I'm obviously plaged with limp
Mode at WOT and even moderate acceleration up steep hills. Turbo is making screaming noise near redline, I notice its louder even at idle. PLEASE HELP.

Among the moderators there is no distinction between removal of the DPF, catalytic converter or EGR. All are illegal and will be dealt with accordingly.
Not to be picky: it is NOT illegal to remove DPF, cat, EGR or ANY OTHER modifications you want to do to your car. You can do whatever you want to the property you own.

Technically, it is only illegal to drive such modified car on public roads.
All of us who have modified their cars are CERTAINLY only using them off road, for racing, etc.

But so is driving over the speed limit (yet a few cars a sold in the US with top speeds exceeding the speed limit; not illegal, just not legal to USE that top speed on public roads).

BUT: rules are rules. And if the owners/moderators of a website stipulate it is not permitted to discuss certain modifications (ditto Uwe over on Rosstech/VAGcom/VCDS for example), then those are the rules.

Just don't scare members or misuse the term 'illegal'.

It is like saying: "guns are illegal" or "the use of guns is illegal". Nope. Just killing people with them is illegal.

malone stage 2 or 3

i'm quite new to TDI club, haven't had time to read through everything but i am looking to upgrade my 2012 2.0L tdi
I am looking to do a stage 2 or 3 malone tune but i just replaced the DPF in my car (105,000km) so i don't want to do a delete for obvious reasons... with the tune do i need to do anything else? will it kill my DPF faster? more regen cycles?
which would be best?

Hey guys, i'm new here. I have one question about ECU's.

Can i upgrade/change my ECU on Audi 100 C4 2.5TDI (AAT engine code), with automatic transmission?

I heard, that it can be done on AAT or AEL, by changing ECU to Golf III ECU, and by changing fuel pump electronic part. But with manual gearbox.

So is it possible to do the same on my Audi?

Ohhhh, don't know. haven't checked yet, but it's an old ECU, because i have AAT engine code.

And i have been told that i couldnt replace my ECU because i have automātu gearbox.

plus we don't all live in the same country, and it certainly is not illegal to remove a few of those in my country. maybe any advice given should have a statement saying it MIGHT be illegal if you live in certain states or countries to remove,or modify, certain items.
the uk is pretty laid back with regards to modifications, especially on older models of vehicle.

What exactly are the various stages frequently mentioned on the site? Are the stages specific to a particular vendor, or are they fairly standardized?
