the car is a 2001 VW Jetta TDI ALH with EGR, can I delete it or will it cause problems?
-
You can delete it, but you'll need a specific replacement coolant hose, and the ECU will throw a code, so your Check Engine light will stay on permanently, perhaps masking other problems. The only real way around it is to get the ECU tuned to ignore it.
Most folks actually leave the EGR in place nowadays... thanks to ULSD there's little or no soot buildup in the intake manifold anymore, and most people report their fuel economy goes down a little bit after a delete.
Having said that, if you want to install a EGT gauge the EGR port on the back of the exhaust manifold is a perfect spot.

I'm new to TDI's and I just got the 2001 TDI ALH with 417K on her, and justn looking for a bit better power
-
OK, then an EGR delete is not the droid you're looking for. ;)
Unlike IDIs, TDIs respond really really well to bigger nozzles. Brian at Roseland in NS has good prices on VEG .205s and .216s... ship 'em to Giles to have them mounted and balanced and for $350ish all in you'll be roaring.
The car has a MAF so don't mess with a K&N... the stock airbox and filter flow more than enough.
ECU tune is your next best bet after nozzles... Malone in Vancouver is very well respected.. you can ship him your ECU or he'll rent you a loader.

What, he'll send some drunk guy to your place to hang out?

I already talked to giles for some injectors and was talking with TD performance about a programmer, I don't want this poor baby to blow up yet lol. I need to rebuild a motor first within the next few years lol. I had it out for a spin today, some haze on take off in first and she struggled for traction which suprised me compared to I've been driving the gf's 2010 city 2.0 or my 300k old truck lol

I borrowed my friend's 98 AHU , which used to be mine. very easy to smoke the tires. I removed the big nozzles because i didn't want to burn my clutch, but it still has a chip, and even without trying, goes through a set of front tires a year.
-
I got a EGR delete kit from dieselgeek.com and haven't had any problems with it. I only got the "racepipe" without the coolant pipe delete stuff. It didn't throw any codes. 2k1 TDI ALH
HTH, Colin.
-
Haha Catlin I am currently looking in to all this same stuff for the AHU swap ;)
How weird, our engines have nearly the same mileage.. I have 423k.. Creepy eh? My intake will most certainly have to come off and be cleaned out as there is a butt load of carbon build up, I'd say about a 1/3 of the intake path is blocked.
Injectors and Malone's Stage 2 (http://malonetuning.com/?page_id=6 (http://malonetuning.com/?page_id=6)) should be pretty hefty power increase no?
-
Injectors and Clutch is on my list, but she needs a new Paintjob this spring JUST before MVOC ;D
-
paint? Paint? PAINT!? cosmetics Catlin? really? :P
Its not whats on the outside its whats under the hood.. ;)

I had malone tune the ECU for my dads 98 jetta tdi. Deleted the EGR, MAF and stg 3 tune. He has helped me along the way and even sent me a spare ECU due to some issues i am/was having.
Haven't drove it yet but will report back.
Catlin, Sam put a PSI box on his dads and it feels good.
It'll haul 2.0ls and AAZs like nothin at all halfway across Canada and midwest US! ;D
-
Hahaha Tom I just noticed you posted this, now back to dleting the ERG? YEs or No?
-
Vince says it is not needed, and as you just cleaned out your intake.. I think your well ahead of deleting the EGR..
I was thinking of doing this as well, but a clean out of the intake might be a better idea.. As you stated Vince, the ULSD fuel has a lot less stuff to soot up the intake.
-
Jeremy this is my thread! get your own!!!! :-*
Just joking, I will eventually delete it, just not yet lol
-
In general there's no winning reason to delete the EGR anymore, in the era of ULSD which leaves no oily residue to speak of.
As well, the ECU will throw a permanent CEL, the engine will take slightly longer to warm up (since the system is water-cooled) and fuel economy is reported to get slightly worse.
If it's not leaking most people leave 'em be these days, particularly in any district with physical emission inspections.

I think Vincent just made a Star Wars joke!
[/pause thread]
-
Jebus.... took you guys long enough.... ;)
On the other hand, most of you guys are probably too young to remember the *real* Star Wars. ;D
-
I have seen all 6 ep. ;) Guy was a genius.

Dont forget about Kerma TDI.
Charlie will do about any tune you want, including EGR Delete.
Getting mine done in a week I think.
-
Effff Kerma... Not a person i buy from.
But you can reduce the EGR rate by vcds-
Channel 3: EGR
-To decrease the EGR rate, increase the number to the highest possible value (typically 33768).
-This will prevent/slow down the intake manifold clogging problem and reduce smoke.
-Though the MAF at idle is still within specifications (370 mg/h) do not use this adaptation on the road :-)
-Again, this EGR setting is for off-road use only !!!
