Message: <blockquote data-quote="Roberto" data-source="post: 468894" data-attributes="member: 8160">If its the valve body, any bmw shop with a scan software like DIS and GTR will be able to spot it as the solenoids in your gbox will register fault codes. Have them clear the fault codes immediately....sometimes that fixes the problem permanently ! Should not charge you more than 50 for all of this.The mechanic who told you 'valve body' immediately is out to make a fast buck imo. Anyway, stuck valves in valve bodies can be unstuck by cleaning out the valve body (vb) with a degreasing solution and low pressure water hose. Sometimes, stuck valves can be unstuck by the simple addition of products such as Lucas Transmission fix (generally only available on ebay not locally) to the gearbox, which break up deposits without doing harm to seals.You have alot of options. Especially if this suddenly happened, and you haven't done anything to your car as yet, I'm pretty sure that you've got error codes in your VB solenoids which have disabled them or put them in something called 'limp home' mode, which artificially degrades their use in order to prevent further damage under normal or severe use.Error codes can often be deleted by the owner by simply disconnecting both battery terminals for about 10 minutes and reconnecting them. However, this procedure may vary from car to car, so I suggest you google for that information. Perhaps deleting the codes will solve your problems straightaway (as mentioned earlier). In any case, I think its a good idea to get your car scanned to see what went wrong....</blockquote>
