Hi. I live in Argentina, sorry for my bad english. My 1998 320ML went on Limp home mode after a service at dealer, they only changed transmission and engine oil and filters, and the famous o-ring at the transmission connector because of a leak, and tried to solve two problems: when placing gear lever from N to R the back light turned on and immediattely off, and low range was not working; but they couldn´t solve either of these problems. After draining and filling again the transmission fluid and looking after the fluid level that was ok, it kept in limp home mode, after several tries now it won´t work even in limp home mode: doesn´t engage reverse or 2nd gear any more. The mechanic says the previous transmission fluid was too old (this ML has 142000km) so the new fluid cleaned something out of the transmission and I have to replace it!!! They weren´t able to read the codes in the computer. I think they did something wrong and there is an electrical problem but I would like myself to read about it in a repair manual if anyone can help me to download it from the net. Thanks a lot.
