I'm a long time BMW fan, usually I work on my own cars except the slightly more exotic one... I have my own diagnostic reader and am very familiar with REALOEM !
Here's a quick run down of my BMW history...
E36 318i Saloon
E46 M3 Coupe
E39 530i Champagne II
E36 318 Saloon
E36 316 Touring
E48 318i Saloon
I do like a bit of Bavarian ;-)
I've just bought an Automatic E36 Cabrio which has a few issues, I'm searching previous posts and reading up before posting any questions.
