Do you run on veg oil?

Check the sedimentor behind the rear drivers side wheel isn't gunked up.

I had exactly the same issue as you. Mine wouldn't even rev past 2500. Fuel starvation issue. My sedimentor was gunked and was partially blocking my fuel lines

It's bypassed I've even replaced the hose again I wouldn't even try veg oil clean diesel with diesel forte every month

If your tdi were to rev to 7k then it would destroy itself, blow itself to bits in a very short time.

A run of the mill petrol engine would struggle to rev to 7k, modern diesels do very well if they are revving at 4k and that is revving hard for a diesel that is why they are so high geared.
 
Had the sane problems for over a week.
Changed fuel pump, replaced injector harness, serviced all filters and checked waste gate arm, movement fine.

My rock was ready to drive off a bridge.

I've been using www.discovery2.co.uk.

Clear description how to do many things (which I used to change fuel pump as I'm only a computer technician lol).

Found his page on solenoid (some people call waste gate modulator and many other names)

See WWW.discovery2.co.uk/waste gate.HTML

I was apprehensive that a solenoid could give me the kangaroo petrol syndrome as I call it.
Boy was I wrong!

Another 10 minute job and omg I have full power and speed. Can't believe something so small could cause problems so big and to think I nearly bought a new MAF sensor!

So anyway problem solved with no thanks may I say to nano com locator who I got no reply from any of them I emailed (Edinburgh guy).

I did get help from discovery2.co.uk and obviously lots of help from everyone here on landyzone.

So a big thank you to all of you on here, (its like a big family Lol)

Thanks all

Regards

Mikey
