    Posted: 13 Mar 14 at 16:26
Had my first contact with customer services and the guy on the phone seemed very nice but although the door handle was a known issue and they fixed it under warranty it was only up to 6 years and my van is just over that. To add to my woes I found some rust under the near side step and when I asked him about this he suggested that I get a van dealership have a look at it to see if it is covered by the warranty.
The nearest one is an hours drive away.
I wonder if it is a cheap/easy fix for the handle if anybody has done it or had it done I would be grateful for any information.
Cheers

Contact them now and keep them busy.

The one who is looking after my woes only works to 2pm each day, calls at 1.55 so the conversation can't go on too long.

You maybe be under some illusion that VW actually gives a dam about a customer.

Email anyway, fill their mailbox for them.

I fitted a new moo valve and this to have done the trick but the van, although 7 years old, has only done 18000 miles. Why should the valve start to fail with such a small mileage?
My contact with the dealer seems to have stalled and I am wondering how long I should give them before I contact VW customer services direct.

Standard VW answer to the rust question, "Feck off!"

The corrosion warranty is a myth on paper.

You will be told to pay £200 to get a paint report and they hope that pisses you off and you go away.

You are a sub human in VW eyes as you own a commercial vehicle, if it was a car it would be sorted.

VW tail light warranty policy.


Tail light warranty definition. When they can't see your tail lights your warranty is over.

Have already had a response but just to ask me for my post code and contact number. I hope just to let me know which dealer to take the van to but may be just to put me off. We shall see.

Your local dealer will probably want to see your van and take some photos of the rust problems so they can put a report together for customer services, so it may well be quicker to take your van to them than wait for them to reply to your email.

It doesn't seem to do anything when the engine is running although it does click when I pull the handle. Having looked at diesel engine runaway on u tube maybe I'll try to get it working.

I also emailed my local; vw dealer about the rust under the handle and am waiting for a response. Will let you know what happens.

Given how VW turbo-diesels work it would probably only slightly reduce maximum power (due to the extra drag of air going around it reducing the maximum possible volume of air).  

At partial power levels the ECU just injects the right amount of fuel for however much air is going into the engine, so no practical effect.  Much like a dirty/partially clogged air filter.  

The story would be quite different for a naturally aspirated petrol engine.

It's a simple/clever idea.  If the volatile gasses ingested cause the engine to overspeed- the increased airflow then automatically sucks the valve shut.  I'm surprised VW didn't think of making the shut-off flap they already have capable of that.  The ECU could shut the flap if the MAF showed excessive air flow.  Maybe they didn't trust that it wouldn't happen in the fast lane just because the ECU was having a bad day... Tongue
.
I think it will disturb the airflow and affect performance/fuel consumption a bit because it forces the air to squeeze around the open valve.  But still, if the van is going well why change it, it might just save the engine one day as Greg says.

So definitely not a snake oil go faster/use less fuel device then LOL

If it was my van I'd be tempted to take it out - it is one more thing that could go wrong.  Although if your turbo seals ever fail it might stop your engine doing the rev-to-death runaway on the engine oil, so maybe leave it on ? (assuming it's a quality piece of kit that won't play up and doesn't need any maintenance ).

Hi

I have been doing some research, just for interest, and have discovered the website of the valve manufacturer. It is a Chalwyn D valve and is designed to prevent what zedzedeleven said ie engine racing when taking in volatile vapour.


This diagram shows how it works.

From what I remember from my days in a chemical factory diesel engines (and maybe petrol engines) could suck in volatile vapour like acetone and methanol causing the engine to race. The van in question was used up in Sullum Voe, so maybe it was fitted with the shut off valve as a precaution. Be interesting to see how it worked automatically.

So it could have been a van used in say, a gas installation?  I bet it is a simple flap to block the intake on command.  If it was mine it would get it off and find out how it works in a nanosecond!  If you do take it off, post up some pics. Thumbs Up

It could be an emergency engine kill I suppose...  Although it's clearly not working.  And it could do with a cable through to the cab.

Hi all
Some extra info on the yellow thingy. It is made of metal and I put the cable strap on it is it rested on the metal tube below it and had worn half way through it. The strap holds it above the pipe, I hope.
The orange handle is attached by a cable to the mystery control and I gave it a pull when the engine was running and nothing seemed to happen. On the metal below the handle is a label saying emergency only but I don't know if this has anything to do with it.
I don't think it is a "go faster" gadget it as in it's former life it was a crew bus in Syllom Voe. It has only done 18000 miles and has probably spent most of the time ticking over to keep the heater working; it can be very cold in Shetland.

Wonder what it does though?  Smile  It's clearly after the air filter and MAF.. 

I'll take a wild guess at it being one of those "cyclonic vanes which rotate the air as it goes into your engine and improve your fuel consumption" snake oil devices.  Unless of course it is an electronic "supercharger"  LOL

Considering what is about to happen to the air in just a few more inches when it gets whirled around in the turbo-charger I don't believe that sort of thing is going to make much difference, except maybe a slight reduction in maximum power due to slightly impeding air flow Wink

hi again

I am still investigating, I liked the cable idea as the sound was just as I imagined a vibrating cable would sound but I tried to remove the centre panel with no success. It seems to be held on with a single screw and plastic lugs. I gave up after some pulling and twisting as I have a bad record with plastic bits.
I ordered a new valve as it seemed cheap enough and even I could probably fix it. If the valve is not the cause I will have a spare part and will spend more time with the plastic panels and look at the cables.
On a different point does anyone recognise what the yellow thingy attached to the air hose is. I asked a local mechanic and he hadn't a clue. At this point I will try to put in a couple of photos but if they don't appear feel free to come up with exciting ideas.
