Yes I did, but was not very successfull. First I realized that the spark plugs I ordered were according to the NGK Website not the correct ones, which ones do you use for the V12? Upon wanting to check which plugs are installed, my toolset failed to have the right socket to get them out. So in terms of progress it was a very unsuccessfull weekend.
I took the car monday to the airport for 130km drive, which worked quiete well without any funy lights coming on. So at least I had a bit of motering pleasure.
Holidays are coming up, so hopefully I will have some time to sort out the things I have planned.
