A drive through wash doesnt wash your car good enough....wash it with your hands with dawn dish soap and warm water and rag..will take a little scrubbing

Common sense

Some people should hire someone to do there work...if u dont know which plug is which just stop....there will be one on bottom and one on side...some have 2 on the side, one is the level and the higher one is the fill port....and they are plugs, not bolts...

warning you, buy a key copy right now, an extra one! they always get lost then you cant change your flat. keep the damn thing in the vehicle, in fact i dont want your wheels and almost nobody does. they can be bought from scrapyards so why would i commit a felony to get yours lmao

Astra GTC 2.0 CDTI white smoke?

I was driving down the road and noticed white smoke out my rear view mirror, it then proceeded to start increasing the RPM to the max, I trend the engine off before it got to the max and let it settle down. I then drained 1L of oil out of the sump, this was because we assumed it had been filled up too much. I then tried it again and it started fine until I revved it up and it went to max again, BUT this time it didn't stop once I took the key out of the ignition for 1/2 seconds. What could the problem of this be? Is this an expensive job?
