Worn door locks? - 4/22/2007 8:32:13 AM    smigel   Posts: 4 Joined: 4/22/2007 Status: offline My 3 door 300Tdi is on 144000 miles and within the last few thousand miles the driver and passenger door locks have started to misbehave.  The remote unlock doesn't seem to quite lift the button inside the door enough to unlock it and I sometimes have to resort to using the key to give it an extra bit of turn/lift..  Having done this at the start of a journey, it seems to settle down over a journey and then require an upwards pull on the button to be able to open the door again.  This is no big hardship, but occasionally with the keys in the car, and the door shut, I have had to resort to the boot to get in! At first I thought it was somewhat of a coincidence, this starting to happen on both front door locks simultaneously, as the car is used 99% of the time by me alone, but I realise that the front locks both experience the same number of lock/unlock cycles... Apologies if the subject is an old one, I had a brief search and didn't see any similar threads. Post #: 1

RE: Worn door locks? - 4/23/2007 3:12:50 PM    smigel   Posts: 4 Joined: 4/22/2007 Status: offline Thanks for reply, Mike.  I have tried the door locking system with the actuators out of the loop mechanically and still have the same symptoms.  The actuators seem to motor over pretty well, and I can't believe that the system would rely on them exerting residual force after the initial actuation (but then I have been wrong before).  I am still left wondering if the door locks themselves are worn in some way.  As you say, the actuators are easily replaced but ~£100 each (so I am told)...  It would be annoying to change them and still have the same symptoms!! Thanks again (in reply to Disco Mike) Post #: 3

RE: Worn door locks? - 5/5/2007 7:34:21 PM    smigel   Posts: 4 Joined: 4/22/2007 Status: offline Solved by adjustment on the passenger side, and replacement of a small spring on the driver's side.  The latter is not available from LR, I guess they would prefer to sell you the whole mechanism.  I searched on eBay for "Discovery Lock" and found a UK supplier for the springs which arrived the next day. Fiddly job, and I now look as if I have been self-harming after having my arm inside the door for an hour or two, but satisfying.... (in reply to smigel) Post #: 4

I got them at www.partsexpress.com Part Number 330-010. $5 US. They work great. Kyle (in reply to smigel) Post #: 5

I've got the same problem with my locks but I also have an issue where the alarm randomly arms and is very difficult to disarm with the key. I've never been able to get my remotes to work (they probably need reprogramming). Just wondering if you had the same trouble. Thanks! _____________________________ Arman 1997 Disco I slowly being whipped in to shape. (in reply to lostsheep22) Post #: 6

Good luck with the alarm issue, I wouldn't be surprised if the electrical switchery at the rear of the assembly rotated by the key was implicated in some way. (in reply to adowgiert) Post #: 7
