More on the EGR Bypass Valve....Modify or Leave alone

Sorry Jamie, long week, didn't mean to "snap" as it were.

No worries Nic...no offence taken.

The results come from the drive cycle that is a totally repeatable test.

Now you might say that they're not real world, which in one way they're not. If we were to take a real world result, they would be much higer than that as no one drives to the required drive cycle.

The point that I'm trying to get across is that an MOT test is a health check only and the EGR/CAT systems do not function the same as they do under a legislative testing proceedure. If you were to have the same test done for an MoT, your test would cost around £300 to £400 every single year to find out if your vehicle is still operating within the tolerance allowed under conformity of production rules.

Becuse the engine is in a different condition at an MoT, you'll never know what you're engine is putting out of it's exhaust.

And correct, there engines will deteriorate over time, which is why we test the way we do to inculde deterioration factors in the results for aged catalysts, EGR and any other part of the emissions system requirments.

So you might as well do the mods - egr bypass and decat!
No one will know, no one will ever check.

If you've tuned the engine, then they are probably beneficial.

As Jamie says, if there is less visible smoke and less fuel is used that tells me the (important) emssions are reduced.

Some BMW owners believe that BMW have spent so much money developing their cars that they are perfect and can't possibly be improved upon. Yet its funny how others are proving them wrong....
I suppose if the egr bypass was £500 they might be more inclined to believe it worked!

(by the way, I also agree the EGR bypass DOES do something that can be qualitatively felt too!) But surely the point re: the above is that BMW have a different set of legal and environmental responsibilities that they, as manufacturers, must obey. We can bend the rules and can be more singleminded in selecting the factors we wish to play up on, if we so wish.
BMW could never market something like the EGR bypass.

Excuse me!, who is proving who wrong? I don't think a small group of so called enthusiasts (that's my polite name) is any fit state to even suggest that they are following the path of righteousness. Damn arrogance.

I thought it was whether an EGR bypass would blow up my engine.................





Oh, and it hasn't done, at least not yet

I think we've established that it won't, not on our cars anyway, which is what the concern of the original post was all about.

I'm not sure who you are calling arrogant, but I hope its not me!
I'm sure you meant those BMW owners with their head in the sand.

For the record, I was refering to those BMW owners who have actually tried Dave's EGR bypass for themselves and found that it does do what he claims, which is what those of us on this forum have also found out for ourselves.

I've been through all the arguments for and against covered in this thread on a BWM forum some months ago. But in the end I realised I was flogging a dead horse due to the arrogance of a vocal few.

The silent majority of that forum's membership must have been bemused at the pig headed arrogance of a few of their community who were quite offensive in their comments. Yet none would actually try one for themselves, though the ring leader eventually had the temerity to ask for a 'free' one to 'evauate' when I challenged him to put up or shut up.
