I have a problem with a 2007 Altea XL 1.9 TDI with about 137K miles on the clock.

It is a BXE engine, I know how bad they can be but this one still has conrods intact :)

It is as flat as a fart. Ok when around town but no go for overtaking or up steep hills.

it is as though the turbo isn't doing much ?

We also have a newer 2010 Altea XL with the same 1.9TDI 105 engine and that goes really well so I have something to compare to.

Can anyone suggest any simple checks to prove if the turbo is working at all.

I have a Carista dongle and various apps etc, what should I be looking for?

Runs nice and smooth for a high miles TDI as it has had oil changes every 9K since new.

It just lacks get up and go.

Any clues anyone ?

Thanks,

Mark.
