Power loss, poor hot starting & info on wastegate

[filip.krticka]

Check the fuel pressure regulator, if you have starting problem. Or the faulty Coolant temperature sensor G62 (at right rear of the cylinder head) could cause this issue.
Check the MAF- hot wire if it is not broken. You can use IPA to clean wires and plug connection. To recognize if the Lambda is worn simply unplug single cable plug ECU follow hardware map.
For hesitance check knock sensors and ignition cable. Simply watch them after dark. If you should see any lightning exchange them.
...and don't forget reset the ECU

the lambda could be another reason if MAF and MAT are fine... Paul correct me if I am wrong whit ths, but the lambda when dies, the ECU protects you adding more fuel to avoid damages...oh and fuel consumption may be a lot higher! cheers!!

No. Almost nothing will happen if you unplug the lambda besides slight change to AFR at cruise. No safe mode, nothing.
Also, no point to screw around with the wastegate spring...

If you have starting problems, it is 100% not the MAF or Lambda. Your car will start fine with both disconnected. It might have issues holding idle, but it will start fine.
