I recommend a trained mechanic to do this

Need more information about the brake fluid leak and what you needed to do to rectify it. Brake pedal feel should be fairly consistent and when it isn't it does indicate something mechanical is sticking and freeing itself intermittently. I suggest you inspect all aspects of the braking system systematically and thoroughly to ensure everything is serviceable. Pay attention also to the correct adjustment of the pedal linkage and if the master cylinder or brake booster servo has been changed at any time, the master cylinder clearance should be checked. Check also wheel bearings for excessive free play.

it means there is a code in the computer that needs to be checked and repaired in order to turn off the light.

Take it somewhere and have it scanned for codes. It will save everyone a lot of guessing.

gray smoke is water ( check water level ) black smoke is oil (check oil level) also check if you are parked on an incline, if back of car is up un air then water can sit in the exhaust over night. and it can take upto 2hrs of driving to get it out. this will also give you gray smoke.

Lots of problems with those roofs. Take it back to the place that fixed it and tell them to fix it properly. Probably air in the hydraulics. https://www.google.com/search?q=Opel+Astra+Bertone.+Message+%27too+slow%27+appears+when+trying+to+open+roof ..

Identical cold start issue on my Astra IE 1996 F series after the engine got rebored - after months the new oil pump was found to be faulty & clogged-up & replaced by the spares supplier - the car then ran perfectly after this. I was told the blockage created a backpressure & the computer was stopped it starting. 16 years later - 10 yrs after the last service covering just 8600km (last 2 yrs car hardly started) has identical cold issues again. It can be driven around & wont take long cold start in our warm coastal winters. The good mechanic seems to be giving up trying to fix my old car but refuses to believe its a low oil pressure issue saying that just makes the oil warning symbol light up & doesn't affect a car starting. I want to check if the engine warning light works on starting showing the low oil pressure sensor is working. But his now busy searching for a Astra specific temperature sensor.

Question edited for a lot more clarity, and sentences. Question moved to an Astra Category. All question need full 'year make model' please. That is a sorry tale. Some garages will disconnect stuff so you have to come back and they will dream up something else that needs fixing. All your issues are electronic and covered by the computer network that connects all the modules and sensors. There is only one way to diagnose those faults and that is by an auto-electrician who will connect a $5,000 scan tool computer and pinpoint where these faults are and fix them. They will often come to you. You can't guess faults like these. https://www.google.com/search?q=auto+electrician+near+me ..
