IBased in Cornwall , I have owned a 2006, 2.5 axd vw transporter/ caravelle for 2 years bought with known limp mode problem at a reduced price. Not an awfull lot of service history pretty sure its orginial Turbo.
Mileage: 365300km-226986mi.

If I am driving around b roads and under 70mph doesnt normally go into limp m. However soon as hit some speed especially with a few passangers / weight in the van goes into limp just flick ignition off and on and re-sets itself.

this is part of the scan

17978 - Engine Start Blocked by Immobilizer

(no units): 0.0


Ignoring 17978 I have read horror storeys of garages replacing parts until its sorted, starting at cheapst parts and if necessary going right through to a new turbo !!!! I dont have those $$$$
I spoke to a vag mechanic who said he never found a vehicle with a failed n75 !!! but often people change coz easy and 2 seperate vag trained mechanics told me a lot more often, than not, its the stuck turbo veins

Would people agrea a relatively easy way to check would be get under the van and move the actuator rod by hand if stiff hardly moves pretty sure its that and saves alll the testing????????

Have read quite a few reports on using mr muscle squirted inside exhaust side of turbo to unstick the veins without removing turbo from vehicle


I would appreciate any ones experience with this , I realise this has been sort of covered in the past but sometimes its good to start a fresh thread so people with to date problems may get quicker answers.



Sorry for such a Introduction but I have read a lot of good recomendations about this site.

Thanks

Sean

Welcome to the forum.


Its nice to see you made an intro on your own. ;)

This is a new forum layout which is owned by a company last year that doesn't give a dam with loads of bugs which have been reported in the new thread. There is no TDI Wiki at the moment or original similes which they refuse to install. It doesn't show the car spec/location.

Add your car specs to your signature that will show on every post you make.

We Are Live - Community Feedback

This has been talked about many times.

I've made a poll which no one has posted in, there are a few votes and comments.

Do you like the new forum features?

Wiki pages have been restored as of 7th December, I asked where is the link it should be on top of the main forum.

Make a new thread in general as we don't have a Transporter sub forum, as I don't want to use your intro for your problem.
