Any one watched Watchdog last night about water dripping from an incorrectly factory installed seal which allows rain water to drip down and sit on cylinder head where the injectors are.

Evidently over a period of time corrosion sets in between the injector and cylinder head which makes it impossible to remove a faulty one although a new tool has been made which overcomes this

If you have one of the above makes, check that yours does not leak, look on the BBC Watchdog website for full details and now warranty phone numbers

Cheers Peter.. makes interesting reading, especially the Vauxhaul responses


Will Vauxhall now admit that this is a design fault and cover the costs of removing and replacing seized fuel injectors out of warranty?

The potential leaking of water into the engine bay is not the result of a design fault. In cases of injector corrosion, it has been identified that the seal which deflects water away from the underbonnet area has been damaged or become detached through damage or other outside influences.


The further down:

Can Vauxhall confirm whether this design fault has been fixed on the new Vivaro vans released this year?

Injector corrosion on Vivaro (codename X83, the model referred to in this Watchdog investigation) is specific to that model. The latest Vivaro (codename X82) is an all-new vehicle. Its design, construction and engine installation is completely different to the previous model.


In that answer they do not deny it was a design fault merely say the new van is different..
 
Sounds a bit like the scuttle problem with the X250. How can manufacturers get something so basic so very wrong?
 
Watched it with dismay Peter :(

crap isn't it.. First Fiat, Citroen and Peugeot vans with "scuttlegate" now joined by this trio...

Is it any wonder I have little faith, or enthusiasm in buying a panel van conversion based on any of these chassis ..

Sad really ..

My Transit does the same, so I am having to make a shield to go over the whole top to redirect the drips, I cannot see exactly where it comes in but it runs along the flat head getting three front injectors and bit on the rear one. There is rust showing there on all. It stood still over the past years until I got it, so the damage is done, but luckily the water level has not reached the electrics plugs on the actual injectors.
 
Many thanks Pete (y)
 
And dont think its all plain sailing with VW T5 either

They have their foibles shall we call them
 
I consider most products have their "character building" moments but really in this modern world where people go to the moon - they should not.

For me it's all down to companies deciding that a money saving measure meets their personal performance targets and so they are happy.

And in the long time we suffer. :(

After a recent job requiring me to remove the passenger headlamp of my MH (Ducato X250 body) I discovered that the scuttle drain was completely blocked, and draining straight into the engine bay. I cleared it, and put it back to the proper route. This lead me to check the drivers side only to discover the same problem, also cleared and re-routed.
I do however have an engine cover on mine (2011 model) so I think I should be OK. Finders crossed. One would have hoped that such a simple job was checked at regular service!
 
Had my Movano work van for eight years and think I had injector problems nearly every year. Started off having all four replaced by main dealer and then the seals were always going causing them to "chatter".
Finally bit the bullet this year and bought a new Transit Custom.
Don't think I would ever go back to Vauxhall .
 
It sort of underlines my opinion that my work Primastar is THE worst van I have ever been issued by an employer!
My company is owned by Nissan but we now buy VW Transporters!
 
aws, post: 1194649, member: 4189"]Simple.. they send their technicians to Swift for lessons ![/QUOTE]
Why Swift ?,
 
Not only a water issue I'm afraid. I replaced the injectors on my wife's c4 1.6hdi managed to get one out but the other three would not budge even after I made up a fitting and used a slide hammer. I had to strip off the top area of the engine and then take it to an injector specialist and they remove them using an hydraulic puller, something they do very often, trouble is then you often need new ones even if they test ok as they can stretch when being removed. Another risk is that the nozzle will break off and remain in the cylinder head thus leading to a cylinder head removal to get the nozzle out. All these problems are due to carbon build up and sometime compression leaking past the injector seat. There have been a lot of issues with modern high compression diesel engines being damaged by carbon build up, especially the engine type in my wife's car which is also used in some ford models, numerous ones have had turbo failures due to oil starvation and engines seazing. It is really important to do regular oil changes and to use good quality low ash oil. When I service hers next I shall be removing the sump to check for any contamination or restriction to the oil pick up and also removing and cleaning the turbo oil feed pipe as these are both areas that have caused problems for many vehicles.

I did have until we bought this car I changed the injectors as it was poor starting and ran rough, so four new injectors and better but not completely cured. As for taking the sump off, this is just to see if I have any carbon build up issues and try to extend the life of the engine. Turbos have failed on these during or shortly after the mot taking place due to the engines being revved a lot higher than normal and repetitively in order to pass the emissions test. So anything I can try to prevent this I will, the sump is fairly easy to get off so it's well worth checking out as buying another car at the moment is not an option, so this one needs to last a year or two more.
 
I had a Vivaro for six years and 50k miles, had injector problems with it in June this year the main dealers were no help at all could not even give me a quote due to this problem I spent over £2,000 on trying to get this sorted out I gave up in the end and sold it. I would never buy another one of these Vauxhall/Renault/Nissan vans I have now replaced it with a Ford Transit

As a slight drift

How do you rate the transit for driving etc as we wont find out reliability issues for a bit

I know of two poeple with new transits that have had to have new engines after they self destructed at motorway speeds. Something to do with oil pump drive chains failing?

The Transit drives very nice we had the custom Ltd 125ps goes well if you rev it but has no torque ie easiley stalled on pulling away. Also has lots of toys if your into all that :)
 
I cured the water Ingress through the scuttlgate on my Fiat by sealing between the gate and the windscreen ,and the centre joint in the gate + the drainage pipes under the rubber grommets that hold the drain pipes with this stuff ,it cures in wet conditions and is flexible ,up to now the engine bay is bone dry ,you can buy this in any builders merchant (it's good stuff for fixing all kinds of leaks that are not under presure)
