Question Limp mode with no dash light?

Hi I have a slight issue but no dash light. The car is a Passat B6 TDI 1.9

It has happened twice within the last week and both times (maybe coincidence?) have been from first starting the car, not middle of a journey)

There is literally no power what so ever when it happens. I would imagine this is limp mode after trawling online but there is no dash lights. The first time I drove around to let engine heat up before I tryed being a bit more aggresive but nothing struggling pushing like 60mph in 5th gear so decided to come home. When I got home I turned it off and thought I would try again and it was fine. Has been fine since done about 100 miles and if anything it feels more powerful (the car wants to wheelspin now &#128545

2nd time was today, went out in the morning and went to 3/4 places all was well........ come home and about an hour later had to pop back out but the car had a lack of power again, this time I pulled over took key out, locked car, unlocked car, put key in and off I went absolutely fine. Again no dash light or warning though.

The car will be scanned tommorow hopefully but as there has being no lights will the ECU log it?

I am aware it could be many things such as MAP sensor, MAF sensor, N75, actuator, sticky veins to name the main culprits but these come with a dash light so any one have any reasons as to why this is happening?

Yes, limp mode will not always turn on the MIL, but there will be a code stored in the ECU. please report back after you have done the scan.
