I've read the How2 on here, googled and read lots of info on forums around the globe and it looks, on the face of it, not a bad idea.

 

3 questions though

 

1. Are there any downsides for daily use?

2. Is it really as easy as folk say?

3. Can it be coded out (during a remap) prior to removing all the hardware, preventing an EML forever?

1) I haven’t seen any and it’s been an excuse to add a catch can.

However, my outlook is that it was designed for a reason.

 

2) It can when you see how the pipe work routes. A little harder with the engine but when it’s out it makes sense. Bowders guide does include a drawing of the PCV system which helps.

 

3) Most have it coded out at the time of the map and have the deletes done before this.

Thanks mate... 

I think I'll go through the vacuum lines and replace any perished ones. 

 

Will do the delete if an expensive part fails. 

At which point I'd go through the instructions as I did it. 

Definitely mess it up otherwise..

I believe @skinnyman has just does to his as he was in the same boat. So he might have some wisdom on the matter.

Wisdom?  You must be thinking of someone else!

 

I suppose I can offer my opinion and experience of doing the job myself.  It may give you the confidence to have a go yourself or it'll put you off I guess.

 

I'll answer your questions first.

 

1. Are there any downsides for daily use?

None that I have noticed.  I did this back in February and have had no issues since.  The car is definitely happier on cold mornings and other than the emissions probably being a bit higher in the first instance, there haven't been any downsides.  If anything, there's a couple of benefits as far as I can see.  Firstly, the car is smoother on cold start up and secondly, there's more room in the engine bay now making access to certain things easier.

 

2. Is it really as easy as folk say?

It wasn't difficult, but there were elements that required a certain level of competence.  The removal of the pump itself was a bit awkward so I dismantled it in situ to get it out.  The top bracket bolt was a pain to remove but I managed eventually.  It made a bit of a mess on the drive as I lost coolant removing the temp sensor housing (I replaced mine with a new one).  It took me about 4 hours in total but you have to factor in that it was bloody cold, I have a dodgy back and I kept being rained on.

 

3. Can it be coded out (during a remap) prior to removing all the hardware, preventing an EML forever?

I used a resistor to overcome this issue.  I took the connectors out of the pump, soldered them onto a resistor, wrapped this up in tape and plugged it back in.  Three months later it all seems okay and there haven't been any error codes.

 

My car also has the N249 and N112 bypass done which again doesn't seem to have affected anything.  I'm going to have a go at the PCV system next as I've already installed a catch can and want to do this last mod to finish everything off. 

 

I'm waiting till I have a free weekend to do this as well as make sure I won't get rained on again.

 

I've attached a photo of all the SAI bits on the drive after they came off the car.

 

Hope this helps but if you have any other questions, just ask.

@skinnyman thanks.. 

 

That's a lot of hardware binned!! 

 

Do like the idea of gaining space (and deleting unnecessary gubbins) 

 

I did a pcv delete on a mk4 golf (pd engine).. think, on that, it just stops derv fumey nastiness going on the inlet.. 

And I think I simplified the vac system on my old Saab.. 

 

We're reasonably competent (she's a mechanic, we can handle most things we're physically capable of - which seems to be less every year now) but I'm very short on confidence so tend to be a bit of a pita and procrastinate a lot. 

 

So many things on the list (house and cars) it's hard to know where to start...

I know what you mean.  We bought our house as a fixer upper in 2008 & we're still going.  Not because it's a big house or anything, it's just that I've spent the bathroom fund twice, the kitchen fund three times and my life savings twice - all on cars.

I have a very understanding wife, a manky bathroom and a knackered kitchen.  On the flip side though, I've had some cracking cars and a lot of happy memories.

Well, the SAI is being mapped out (stage 1 next week) and the plan is to remove the hardware over the summer. 

It'll be a joint effort, probably get swmbo to do the stuff under the car..  she's not going to like the look of all the vac hoses etc up top.
