UK: 2.0 TDI ultra engine no power
Hi maybe long shot . I have had audi fit new turbo which had expensively not fixed the power issue. Car has had dpf gutted and mapped out . Actuator and converter all new and map sensor new all working . Is this likely to be the dreaded egr cooler as car just has no power and smokes bad out the back .

If car is smoking out back, what color is the smoke, as that's a big clue? White, billowy smoke means coolant is leaking internally (EGR Cooler internal failure, a head-gasket leak, etc), whereas heavy black smoke generally indicates a fueling problem. Bear in mind, with the DPF removed/gutted as you say, the car will allow some black smoke when under engine load, etc. Does the engine appear to run smoothly, just with low power output, or is it shaking/bucking and acting crazy.
Normally, you begin by providing results of a full diagnostic scan, as well as year/model/mileage of car. If it is down on power, it will almost certainly have some trouble codes stored. Sometimes you may see a fault code that appears as possibly unrelated to the issue, but in fact it will be linked to the issue either directly or indirectly.
Check your coolant reservoir tank to see if losing coolant; a very simple check. Same with oil level; oil too low/oil level rising are indicators, so you need to understand all the symptoms that are presented by the car. Low power and falling economy numbers can also result from a carbon clogged air intake, which is a by-product of the EGR Cooler system. A vacuum leak can also result in several bits not being able to do their jobs well, if at all.
Check the easy stuff like coolant and oil levels, and if you don't own a VAGCOM scan tool already, you should get one, so you can see what's going on inside the car rather than making (expensive) random attempts at parts swapping to see if that fixes anything; that's what Audi dealers do...semi-random parts swapping until they eventually find what is actually broken, which is your wallet.
Good luck! Gather more DATA on your symptoms, when began....etc., etc.
