EGR should we all be more concerned

Then he has no idea about diesels. He's not alone.

My local VW service manager is a South African... I asked if they can fit a provent. I used phrases like "I've read" and "could it be beneficial"... you should have seen the look on his face. He could out "disapprove-stare" my Grandma!

Needless to say for the 50,00km service the provent is comming off and it'll be in stock form again.

Why? It is your car and Provent does no harm to the engine (when fitted correctly), it is actually beneficial. I have Provent in my T5 and had some warranty work done on the engine and didn't have any problems with my dealer. Maybe Solitaire Automotive is more knowledgeable.

I think if you saw the provent in an engine bay and hada clue what you were looking at, then surely all one could think is "thats a good idea".

Any mechanic worth his salt should know it.

I've seen this type of behaviour from OEMs before.

I had a similar experience with the manufacturer of famous yellow haul trucks - $4M a pop over 15 years ago. Recognised a potential improvement to the air intake and lubrication systems, trialled both mods on several units to prove its value, reported results to OEM. This was backed up by tear down reports, lube analysis and filter sampling.

Site was told in no uncertain terms, in writing, that the "sky would fall down" and our warranties would be void... We rolled out the mods across our fleet and sent the data to our sister mine sites. Real world reliability was valued over a warranty that we would HAVE to use.

Next haul pack model incorporated both mods! Needless to say we sent a "please explain"...


The ProVent is staying on my T5!

I've got a '06 TDI got worried reading all these threads so I pulled the EGR valve and inlet manifold off.

Was at most .5 mm of soot on there and less in the manifold. Gave it a clean but in my honest opinion it wasn't required.

Btw my car has done 110,000 km without a clean.

Does you TDI have a DPF in it?

[Greg Roles]

GT TDI, the only Golf with a DPF, released late 2007, so no, he's DPF free.

Glad YOU had a good experience. Not everyone is so lucky!

I just had my '05 TDI serviced... $500 to replace EGR which is "Blocked and leaking"

*sigh*

So with all the heavily sooted/oiled EGR valves/manifolds do we know if these are from vehicles
that are used mainly for around town driving use, has anyone come across one in need of cleaning
that has been used mainly on long hi speed driving.
Can we pin point the use of car condition to the cause of the problem.

So I thought I should quickly share my EGR experience.

I have bought a Multivan 2.5 TDI that had done 200K in the space of 6 years.

I decided to remove the EGR and have to say that the sad state it was looking, explained the issues I was having. It was not smooth to drive, very notchy. I was worried it was the transmission. The EGR was pretty caked with soot and the intake was as well. I removed it and installed an Allard Power Pipe EGR Delete and instantly the notchiness was gone. The following week I removed the intercooler and cleaned it up and that had quite a bit of oil in it and I was happy to have that gone.

Overall, I understand that the EGR has a place, but from my experience I am not interested in having a mechanical device in there adding more soot to my engine than required.
