Clio 172 Limp Mode after reshell.

[LukeSi]

Hi guys,
I'm in the final stages of reshelling my 172 cup and although it is now running it is in limp mode. When I plugged it in the faults are Lambda and TPMS. I'm assuming this is probably down to the big white connector in the fuse box but just wanted to double if there is anything else it could be?
Cheers

Can be caused by a lot of things, in my case a dead ECU 👍. But, assuming that all components were fine before the shell swap, I would first go through all the connectors that you've disturbed. Were you careful removing the wiring harness through the bulkhead?

Used the engine harness from my car and main harness from the new one. Both were running driving cars prior to being stripped, (got the new one as a rolling shell)
