Good day,
My name is Paul Iroha, I am writing you from Nigeria.
I have an issue with my 2002 VW Bora (VIN: WVWZZZ1JZ2W000258), which is so strange to me. I have a "no communication" issues between my Engine control module (ECM) and my transmission control module (TCM).
When you scan (with VCDS Lite) the TCM, these codes are gotten: 00518, 00529, 00545, 01314. On the ECM, you have 01315 code. On the CAN gateway, 001315
Now, when you start the car for the first time in the day, it revs up and attempts to stall. The second and subsequent starts follow the normal start sequence.
When you engage the car on drive mode, the car shifts normally from gears 1-4. After some time, it will now stay in gear 3 and will not upshift or downshift from there. If you turn off the engine and restart the car again, the shifting returns to normal. This cycle continues once in every 2hrs or your driving pattern.
The power feeds and grounds to both TCM and ECM are good. The CANBUS wires resistance on both modules re good(62 ohms as stated in the technical service bulletin). When you check some measuring block values on the TCM, you could see communication between the VAGCOM and the TCM.
The fuses of these modules are also very good. The relays are also in good order. I have cleaned the throttle valve body also.
I have done everything I could but cannot get to the cause of this mistery on my car.
VW dealership does not support this car anymore and really couldn't help me.
I love this car so much and would not want to let go.
Please any assistance to unravel this mistery will be greatly appreciated.
Thank you so much.
