Fixed my own KESSY. 2 Mosfets and 4 resistors on the left rear door module. Problem solved. Sorry, I don’t know anything about Autoronics in UK.
A new PCB $200! Thats is still a lot cheaper than going to a dealer and getting a new module which by the way is obsolete and they want you to get 5 modules so they can talk to each other. They wanted $4,270!!! I fixed it for $14!

 

You know, doing things like that is the reason VW is not posting record profits! Think of the harm you are doing!

Get a used kessy on ebay. A carprog programmer and do the job for less than 100€. Just get the same part number as what you have. Do a vcds scan or check the part number on the old kessy.

Same number and same ending letter(s)

And be careful about lhd vs rhd modules. Get the one that fits your car. I already made the mistake of buying a door module from germany and not checking the rhd/lhd drive spec stuff. I toolk it for granted i was getting a lhd module from germany and ended up with rhd module from the uk.

Yeah never thought about that good point thanks.

 

Well Autronics have just told me they can't fix or test my kessy and are sending it back, my car has been immobilised (sorry for the pun) for 16 days and prob 5 to 6 more for it to come back, i have looked for a S/H replacement but can't find one with the same letter on the end of the part number. looking for a solution to fix this kessy. The battery voltage has been stable at 12.58V for the 16 days, if the kessy wos installed the battery would be flat in 3 to 4 days.thanks for any help. Vaughan

 

What is you kessy part number? You can probably get away with an updated version.


Sent from my iPhone using Tapatalk

 

mine is 3D0909135L

 

How will i know if i can use a updated version, this would be the best option i think.

 

What makes you think that you don't need to just have the mosfets and resistors replaced?

 

Autronics in the UK have tested the unit and told me that they were ok, i sent it to them when i came across there advert about kessy repairs, you send your module to them they repair it and send it back no programing required. Mine has what i thought common problems no keyless lock or entry and a battery drain.

 

Here is one L version from Europe:

Pardon our interruption...

Latest version is apparently 3D909137FX. Best way to find out is to go to a dealer and give them your vin and ask for a kessy module replacement quote. They will give you the updated version. Remember you still need reprogramming the new kessy.
You have sellers on ebay selling kessy modules with pin and ready to use. I don't have any experience with this but you can always contact the sellers, give them your touareg model and year and get the info you need.

Hey TRespect i gave my local VW dealer my vin and the replacement kessy is in fact the 3D0909137FX, i have purchased a second hand kessy with this number and a pin number from ebay. The dealer said he can program this to my car i am just concerned that it will match up with the rest of my car, the dealer is unsure but said that is the one he would fit if i just booked it in for a kessy problem. do you know if i will have any problems with the newer kessy, thanks Vaughan.

 

I have just checked with my local dealer and the 3D0909137FX is the replacement kessy but they want $1900.00 ex Germany.

 

I don't think you will have any issues if the dealer is ready to program it for you. How much are you paying for the whole thing, kessy and programming?

Kessy 250.00 pound, with freight about 500.00 Ausy dollars. VW said about 1hr labour so about $150.00

 

O and i got my kessy back from Autotronics and it doesn't appear to be draining the battery but the keyless entry and keyless lock still dont work

 

250 pound is too much for a used kessy. I've seen fx versions for less. 150 for programming is ok.

They wanted 300.00 i thought i did well now i am disappointed haha. i will be happy if i can just get it fixed.

 

No way. Let me check the price of that thing. Did you ask the dealer for the kessy price?


Sent from my iPhone using Tapatalk

 

I see 738€ in the vw catalog. Why the 1900$?

That is the quote that the VW dealer gave me and it is a trade price,

 

Mmmm. I still don't understand but ok get the used one and program it at the dealer. The dealer has the tools to adapt it. If he fails well then you buy the carprog tool and do it yourself. Carprog is 50$ on aliexpress.

Ok thanks for your help, i will update when i receive the new (to me) kessy fingers crossed, the kessy comes with a money back warranty.

 

Good. Don't forget to come back with a happy ending [emoji23]
I had a similar issue two weeks ago with the comfort module. My third brake light wouldn't shut off and the left brake light stopped working. I had a spare upgraded comfort module I bought on ebay. Last version for the T1. I plugged it in and voilà third brake like started working as expected and left brake light was back to life again. I got the module for less that 50€ with shipping.

Well no happy ending for me, today my car was booked in at the local dealer to program my secondhand KESSY and they said i could wate as it should take less than a hour. Well after 2 hours they told me there was a problem, the car would not communicate with the new KESSY and wont start. ( i gave them the new pin number) 1/2 hour later they told me they got it started but only one key was working. (both batteries are new and were working) 1/2 hour later they said it wont start and we are going to put your old KESSY back in.1/2 hour later they gave me the car back and said only one key will program at a time so you will only be able to use one key. They told me they would need the car for 2to3 days as they have to wipe the memory of the KESSY and program a new one. HELP!!! thanks Vaughan.
