hi, ive scanned this forum and the internet, can anyone provide specific instructions: can anyone advise more about removing and fixing damaged 'gear shift module' / 'selector lever module 'in my W202 c220 cdi 2000 I would also like to know the MB part number, as it is 722.699 transmission(5 sp AUTO - tiptronic), so i can online search/order. maybe there are alternatives? currently, it's got the classic 'limp-mode' (stuck in a low gear and can only get reverse from P, and P with the key off) and no dashboard gear indicator. this seems a common fault on other vehicles, the circuit shorts or gets water damage and we are told to have it replaced approx £600 parts plus labour. have just had MAIN DEALER do a 'star' diagnostic today, very helpful: P1856-01 P1856-03 P1856-05 selector lever module position detection has failed. service manager said its probably the gear selector module need replacing. thats good news for me, easier than dismantling the transmission itself i searched and found interior photos on this site http://forums.mercedesclub.org.uk/showthread.php?t=72442&highlight=p1856 this video explaining the cicuit operation is also pretty cool: http://www.youtube.com/watch?v=qbVJ_p6bTig but no procedure list for removing or splitting it down i am an expert engine builder/technician so seems worth it if it's just repairing worn copper tracks and wiper contacts which i suspect. i think i would remove the surround, and centre console, check for a loose connector first, then proceed release clip from underside linkage, then what? if this is such a common fault and the damaged bit is cheap, then why are they so expensive new or used~? so why cant i replace ONE worn electrical wiper under £800? when its a 12 year old vehicle worth about £1200 fully working ! tiptonic was so rare in a W202, perhaps i can use a 5speed tiptronic lever from another model?
