Daniel Ricciardo’s power loss in Monaco saw him string together one of the best defensive driving performance you’ll see to keep Vettel and Hamilton at bay.
Red Bull had initially suspected that damage to the MGU-K element had resulted in the power loss. However, further investigation before the Canada GP has revealed that the power loss was actually caused by assembly of the power unit.
Hence, the MGU-K element of the engine was actually left undamaged.
If the MGU-K element would have actually been damaged, Ricciardo would have had to face a 10-grid penalty in Canada.
The 2018 regulations state that each driver is allowed to use two MGU-K, energy stores and control electronics.
Ricciardo had damaged his first MGU-K at the Chinese GP during FP3 after which he was forced to switch to his second MGU-K.
Red Bull have had issues with their MGU-K
According to Renault Ricciardos MGU-K can be used again despite Monaco issue. So he will avoid grid penalty at Montreal. Marko confident Red Bull can challenge Mercedes & Ferrari with low tyre deg, good traction & new Renault engine.

Red Bull have had an issue with the MGU-K element as Max had to switch to his 3rd MGU-K element and would have suffered a grid penalty, but it did not matter in the end as he was already starting from the back of the grid.
Ricciardo would be thanking his stars that he won’t be slapped with a grid penalty in Canada as that would have hindered with and hampered the momentum that he had gotten on his side after the Monaco win.
