So... Just moved to europe and picked up a second car. 1990 318i and am happy! For an 18 y.o car it's great. Now just the finer points to resolve. Brake warning light doesn't go out - but I know it's not the brakes cause they were just done... think the previous owner burned through the sensor and didn't have it replaced when brakes done... Only two big probs are that it "pops" out of 4th more often than not (If I fix it... it'll be a mechanic cause that's beyond my abilities...)
BUT I may tackle the sunroof. Manual opening, seal seems old/crusty and dried out (despite Dutch fall

) It opens best when pushing down on it as you crank, and pushing up when closing. Crank skips a bit, indicating to me some teeth are missing. Can't find a euro spec manual for it and the one online doesn't have anything on sunroofs.
Anyone know how to make this smoother? Is this a DIYer job? Is it easy to replace a seal? Anyone know where to get pics/instructions on line to do this thing?
OR do I just say to heck with it and take it to a dealer!
Thanks for any and all advice.
