Sup fellas 

So wife's dad got the above car. Hardly any power in any gear. I'm thinking the turbo snack erred or most likely the waste gate has stuck open.

My theory right and if so how do you test such things? I learned the theory in school but I've never had to get to one.

Any help greatly appreciated

Have a look at turbo,there should be a rod going across it to a flap,if its open you will feel the gap,or remove a pipe and see if the vanes spin freely,as it could be seized,if it has seized you need to find out why,also if it is a new turbo job,do oil and filter change.

Thanks martin/

don't suppose you got a piccie? I take it if it is the turbo its a simple remove / replace job?

No i havnt mate,have you looked on autodate?

You need to check the the vac hoses first.

With limited tools the only thing you can really check is as mentioned that the turbo vanes spins freely. Touch the shaft not the vanes.

Diagnostics can test the turbo actuator electronic box which actuates the vacuum feed.

Any codes with your new toy? (n57 valve)

The turbo variable vane movement and associated pipework can be tested is you can get your hands on a vac gauge.

Split/ rubbed hoses cause issues.

Engine code/ diesel?

Did you check fault codes ? As Other say check vac pipes

+1 on checking vac pipes,is this the old tdi lump or the later Pd lump?,engine code?

[henryd]

Don't assume turbo just because it won't go,many other things can cause the problem,maf being one of them and they rarely throw up a code for it .

Thanks boyos

Sorry, yeah shoulda mentioned..... Passat 1.8 TDI on a 2000 plate

So, i'll check vac pipes going to and from turbo. ill see if theres any codes. and i presume the inlet connects in someway to the turbo so i can remove this and spin turbo by hand?

Plenty of things can cause lack of boost including the likes of a stuck open EGR valve etc.

Thanks mark,

anyone familiar with this engine and possibly have pics of the wastegate, pipes, turbo, egr valve etc. im just a bit scared as never even held a turbo before lol

[Marks DTM Calib]

Well we still don't know which engine it is, it could be the old 8V direct injection diesel or the PD given the age.

And there may well not be a waste gate either.

Check the hose hasn't popped off the turbo, happens quite a bit and can lead to a diagnostic tail chase if not checked first

It won't be a 1.8 unless its petrol powered,diesel is 1.9 unless its the v6 ,engine code is written on a label on top cam belt cover and under boot carpet on a stuck on paper label
