Power loss

Hi. My 53 plate a4 awx 1.9 has been parked up a while but before we parked it up there was a turbo issue. So replaced all usual. N75 valve, turbo , various sensors. But never cured it. Went to a local specialist and he said maybe the ecu is ********. Would a 2nd hand ecu be worth trying as a replacement

Did you check all the braided vacuum pipes? Split or leaking Vacuum pipes are one of the most common causes of turbo issues on VAG 1.9 tdi's.
Sticking turbo vanes too.

Yes replaced all pipes with silicone pipes. Will plug back in and check fault codes I got. One was an engine mount one was a temp sensor and one was boost pressure senser
