£160 seems around the going rate.

You buy a car which costs over £35k new and are complaining about £160 for a key?

i bought the car on the basis that the key fobs weren't working. £3250 for a 330d se touring, 55 plate! FSH.

Is it worth breaking open one of the fobs and changing the battery anyway? I understand they use a small panasonic cell

Is there a fuse for remote locking? Sounds like wishful thinking

You should have checked the costs involved before you bought. Then you would not be moaning about the prices having knocked the seller down by the correct figure.

You live and learn but for now you will have to pay up if you want a working car.

I think you will find that the water ingress problem only affects the estate/touring models.

As this is a touring,the problem could be water in the receiver unit ,under the gate spoiler ,or broken wiring from the tailgate to the body.(very common)

Ok, i took the rear spoiler apart today. The ribbon which plugs into bottom left of unit, has split, on the narrow side, which trails left (RHD) into the bootlid. Please see photos below

When i disconnect the unit, the radio reception is worse (understandably) as i am disconnecting the amplifier. I therefore assume there is power going to the diversity unit, although i couldn't find a live/ground wire to check with the multimeter.

What is the purpose of the ribbon shown? It has two tracks, a wide and a narrow one, like i said above, the narrow one has sheared off, which trails left, the wider one trails right, and it looks ok.

Also the rear wiper doesn't work. The washer pump is fine, though the nozzle is blocked and needs replacing.

One last thing. The washer pump doesn't work at all (no noise) if the bootlid isn't closed properly, nor does the independent rear window open, again , if th ebootlid isn't closed properly. Could any of these be linked?

emote locking now sorted. It wasn't the amp, it was a broken wire in the black rubber loom by the bootlid hinge! soldered back together, now all is fine!
