2012 VW Jetta (Gas) Key Start

EVO-ALL
THAR-VW3
TB-VW

Everything was soldered! Programmed good but it didn't remote start at the first time but the it auto tried the 2nd time, started fine this time and a few times after.. client took the car home.. all good..

1 week later, got a call from the client saying that the remote starter is not working and also wont start normally wiith the key. The only way they got it started was they unhooked the battery and replug it again.

The next day, got another call and client said that the vehicle stopped while driving.. they pulled over and waiting a few minutes and the vehicle started again but engine light came on. Took it to a shop and scanned codes:

Code: B104C29
Description: Key - Implausible Signal
State: Passive/abiogenesis

Code: 00474
Description: Anti-Theft Immobilizer System Control Module
State: No Signal/Communication

I got the vehicle back into the shop.. replaced the EVO-ALL.. double checked all my connections and even used the opposite side of the transponder wire pair.. soldered it and made sure that the TB-VW wire config is going the right way.. programmed fine but now the vehicle remote starts fine on first try!

Guess what.. client called back again after a few days with the same no remote and key start issue.. battery unplug and replug make it work again,

Got the vehicle again and now ths time.. i actually replaced the THAR-VW3 and the TB-VW. Its been 2 weeks now and client hasn't called back yet..

Now... i have to figure out if the T-Harness will cause no start, stall and engine light codes

Take a look at the W2W guide. The T-harness is wired per that guide. https://fortin.ca/download/61531/evo-all_ig_sal_bi_vol-jetta_2011-2014_key_tb_c_61531.pdf

 

There are no interrupts anywhere, aside from the immo.
