Is the word consertando the same in Brazilian and European Portuguese?

No

The difference is primarily grammatical and usage-based. While the word "consertando" (the gerund of the verb consertar) exists in both dialects, it is used very differently.

In Brazilian Portuguese, the gerund (consertando) is the standard way to express an ongoing action (the continuous aspect). In Continental Portuguese, the gerund is rarely used for this purpose; instead, the construction a + infinitive (a consertar) is the natural and standard way to express that an action is currently happening. Additionally, the vocabulary used alongside the verb often differs (e.g., celular in Brazil vs. telemóvel in Portugal).
