Need Advice Please .. Re T5

[MultiplexMan]

Noddy,

1. Turbo would be an "unlikely" source for the gearbox problem described. A "loud rubbing noise" from a turbo is usually followed by immediate failure and fire

If it is a turbo bearing/lubrication problem - this can easily be diagnosed with basic vibration monitoring tools (machinery analyser).

2. No fault codes from the transmission?
Something should be evident via VAG-COM if the dealer test drove the vehicle with VAG-COM plugged in and data logging. This should be one of the first things checked.

3. No bowing in my roof either (T5 SWB Kombi Beach). This is a very simple item to fit. A couple reusable plastic screws. Post a photo if you can. Even a dealer should be able to fix this...

I know how disappointing it can be when you make a purchase and things go wrong. Either give it a 'reasonable period" to get sorted or lobby VWA for an exchange...

Good luck, MM

Thanks MM.
Today a "Damper" was inserted into rubber hose that runs from intercooler to turbo...just after the metal pipe ..same radius as hose....sorry for my lack of mechanical knowledge....this was done at suggestion of VWA Technical.....it is supposed to even out the air flow from turbo to alliviate the whizzing noise that occurs ..apparently ....in some 128kw motors when they rev at about 2500 rpm.......they did this because the VWA rep who drove the vehicle thought the whizzing noise was unacceptable. I have checked a number of new 128kw motors built after Sept 2007..the build date of my motor apparently...but none of them had this fix from the factory...so must only occur in some vehicles and only fixed if complained about..the damper does stop the whizzing noise...only wish it fixed the clunking.
Meanwhile the service manager and workshop controller continue to witness the clunking sound that occurs somewhat regularly when the auto changes from 1st to 2nd.....i was present today when the onboard computer was again tested for errors in gearbox...but nil detected.
There is genuine headscratching going on with VWA. re this problem.
I am in full on negotiation with the dealership for an exchange vehicle now....Don't know where it will get to but not letting up as have spent a packet on a vehicle I have had in my possession for only two of last six weeks.
Everyone I deal with seems genuinely perplexed by the issue and keen to help...hopefully get some idea what they are going to do early next week.
To quote an oft used phrase..."I'm over it"
Will keep you informed
still hoping for someone out there to come up with a possible suggestion of what this problem is.
many thanks and kindest regards
Noddy

ps. they are about to order another roof to try for a fix. for the bowing...the third one........I happened to be at Tysons in Revesby late today..noticed they had some just delivered LWB T5s they are doing up as campers...guess what ...two of them had bows in the roof...interesting....however, they don't worry about it as they cut roof out anyway as they install pop tops.

What a palaver !

I've never heard of a "whizzing" noise in turbos (except for those that had bearing problems), let alone an air "damper" being installed on a 128Kw R5 motor before (and because I've got that motor in my van I've been following any R5 problems fairly closely for nearly 18 months). Did it reduce performance at all, as it sounds like it could inroduce some reduction in air flow to the motor ?

I wonder if VWA would consider letting a transmission specialist have a look at your auto (seeing as VW obviously don't know what is wrong, let alone what to do to fix it).

As far as the roof goes, it brings to mind an old saying: "If you keep on doing what you've always done, you'll keep on getting what you've always got".

I'm sory you've had so many problems with your van, and I'm not surprised you are sick of it.

Greg, I have not taken possession of the vehicle because they still haven't fixed the problem.
The damper is supposed to even out the airflow. I have no idea about impact on performance....there must be an issue out there re this whizzing noise as the part that was put in looked fairly intricate....as i said,maybe they only fix it if complaints occur. Perhaps most people think it is just a normal turbo noise ..just as the service blokes thought,.
Do you notice any slightly high pitched SCHZZZZZZZ type noise when you are accelerating. How many kilometers do you have on your vehicle. Do you notice any roughness when gears change.
A technical specialist is supposed to be coming out to look at vehicle in next few days...so we continue to wait...
thanks mate

Sounds like VWA need to get there hands dirty and actually look at the transmission instead if reading Computer Diagnostics.

I agree with Greg get a Trans. Specialist to take a look if VW are willing to pay for it. (or just phone one see if they have heard of anything like this before)
