EGR valve links hot exhaust gases from exhaust manifold to intake manifold via a "valve" that opens and closes based on instructions from ECM.

Don't think you could actually block the intake to the EGR valve unless you actually remove the valve and plug the opening left in the exhaust manifold where the EGR valve would have normally sat, then also block the port open on the intake manifold.

do you gain anything off removing the egr valve?

He probably has a bad / flaky EGR due to the bad diesel quality over there but he also has a diesel engine (TID equipped cars have a Diesel engine)

I really don't believe you gain anything in performance by removing the EGR and you may actually lose some in the cold weather. Further more, you may not even pass inspection if you do since the EGR is part of the emissions system.

The function of EGR is to route some of the exhaust gases back to the intake manifold. Without it:
- longer warm-up time
- constant check engine light
- a little bit more of pollution

You can block it at the pipe from exhaust (to EGR), but much better is to take it off and clean it, every once in a while.


Pozdrav :D!

The EGR valve is used to keep the cylinder temp below 2500F. This keeps NOx at a minimum and prevents pinging. If the engine was designed to work with an EGR valve, disabling it will not only increase emissions but will affect performance. Fix it.

Anyone have any pictures of the valve in question? I'm experiencing some of the symptoms, and it could be the culprit.

A Saab gasoline engine with the EGR(exhaust gas recirculation) is quite rare..

The Diesels from Saab and VW are stuck with this high maintenance unwanted device.......
I believe it can be cleaned every 30K miles or so, hopefully.....in Croatia, every 15 K ???

When the Diesel fuel is really clean (nigh zero sulfur), this ERG may be good for 100K miles...

Many VW postings on this subject on the TDI board...
