The remote part pulls away from the blade so easy replaced .
Just don't lose the immob chip inside.
I'd you only got one key I'd suggest looking at getting a spare even if it's a cheap cloned solid key always safer to have a back up .
The battery codes denote the size 20mm round 3.2mm thick...
Dig up and old thread .as I can never find it .
Mine is 55 plate pre facelift .
Changed to 00151 (still too skitty for me)
Managed to code 00181 - now perfect. (for me anyway)
But then I was bought up with manual steering RWD cars with no gizmos so used to a bit of weight
As fozzybear said connect up the supply properly and better still from the battery with a decent guage wire
Start dropping the bass and you'll be wondering why your amp / stereos is cutting out or worse still your dash and Speedo start melting
Ooh And a fuse
It will not only be safer but...
Sounds daft but want to get the low down on vapers the technical side really
Just toying an idea to see if could setup/make a remote one in some way.
Just think long lasting times and on demand air freshener lol
Could be subtle difference between the two such as the angle of the spindles casting to compensate for the screen rake. Or the length of the rods
I can see why your asking. Sadly not had both side by side to compare
The part number difference would suggest not
The first 3 digits are for the specific model or engine etc
Next 6 are group and sub group .as in body / wiper linkage
Then letters for specifics as in base or gti etc. Can be doubled up if modified or upgraded and even X for exchange items etc...
Needs a physical check then to be honest .
Just replaced turbo on same car .previous owner had attempted just the same as you described .resulted in his turbo breaking off the inlet and munching up the turbines .
Ripped door apart to replace the lock mech anyway and found the regulator was missing .ALL OF IT lol
Glass took 2 hours to get down as they decided to cut out the mech and silicone the glass in place OWCH
Found a mech at scrappers and swapped motors etc over
Might help shed some light in the darkness .
If you can post that pic might get the model sorted and barrow down the Instructions
Don't ask me where exactly sadly but I seem to remember there was a way in vagcom to read the lock switch status 1 n 0 to diagnose door lock operation
I'll dig about as I've written it down somewhere
Time being check inside the rubber tunnel between the door and the car. Might just be a broken...
