Vehicle Diagnostic Timeline and Dealership Communication Analysis - Volkswagen

Vehicle Diagnostic Timeline and Dealership Communication Analysis
VIN: 3VWE57BUXKM218251
Model: 2019 Volkswagen Jetta

This post documents the vehicle’s diagnostic history in chronological order, followed by a comparison to the dealership’s written statements. All quotes from the dealership representative (Colin) are taken exactly as written. No interpretations or recall references are included.

The goal is to present clear facts based on the vehicle’s ODIS engineering log and compare them to the statements made by the seller after the issue was discovered.

Diagnostic Timeline

All timestamps and mileage readings come directly from the ODIS long scan.

  1. October 8, 2024

Module: Brake Electronics
DTC: C113B00
Description: Hill Descent Control Button
Mileage: 156,662 km
Notes: Early irregularity in the brake switch circuit. Electrical, not mechanical.

  1. May 31, 2025

Module: Body Control
DTC: B147A18
Description: Key 2 low current
Mileage: 170,346 km
Notes: First sign of electrical instability in the key receiver circuit.

  1. June 24, 2025

Module: Access and Start Interface
DTC: U112300
Description: Data bus error
Mileage: 170,999 km
Notes: Recorded CAN bus communication irregularity.

  1. July 18, 2025 (Critical)

Module: Transmission selector system
DTC: B116229
Description: Selector lever Park Position lock switch signal implausible
Mileage: 171,778 km
Frequency counter: 135
Notes:
The selector lever Park Position system logged failure conditions 135 times before the fault was promoted to a stored entry.
The timestamp in the ODIS freeze frame shows this fault was active two months before the vehicle was sold.

This is the only date ODIS provides. It is a direct extraction from the log.

  1. August 20, 2025

Module: Body Control
DTC: B147918
Description: Key 1 low current
Mileage: 172,641 km
Notes: Repeats the earlier key circuit irregularity.

  1. October 21, 2025

Module: Engine Electronics
DTC: P2B9F00
Description: Coolant Pump B underspeed
Mileage: 175,679 km
Notes: Single occurrence, consistent with transient voltage behavior.

  1. November 2, 2025

Module: Brake Electronics
DTC: U112300
Description: Data bus error
Mileage: 175,858 km

  1. November 6, 2025

Module: Access and Start System
DTC: U140100
Description: Function restriction due to overvoltage
Mileage: 176,295 km

  1. November 12, 2025

Module: Passenger Door Electronics
DTC: B132054
Description: Rear passenger window regulator
Mileage: 176,436 km

Pattern Summary

Reading the data in chronological order shows three phases.

Phase 1: Early irregularities

Brake switch irregularity

Key low current

Bus communication errors

Phase 2: Major failure before sale

Selector lever Park Position fault appears with 135 occurrences

Timestamp places this fault on July 18, 2025

Sale occurred September 19, 2025

This confirms the Park Position failure is pre existing relative to the sale date

Phase 3: Cascading electrical symptoms

More key circuit instability

Coolant pump underspeed

Overvoltage

Window regulator configuration issue

Repeated CAN bus errors

Dealership Statements Compared to Diagnostic Data

Below are direct quotes from Colin compared against the factual timestamps in the vehicle log.

Statement 1

Colin:
“The sporadic issue happened after sale has been done.”

Diagnostic Record:
The Park Position fault was promoted to stored status on July 18, two months before the sale.
135 occurrences were logged before that date.

These entries contradict the claim that the issue began after sale.

Statement 2

Colin:
“I am unable to confirm any instances as to when you have been lied to as the vehicle did pass safety and the issue happened after the vehicle has been sold.”

Diagnostic Record:
The ODIS timestamp for the Park Position fault predates the sale by roughly 62 days.
The fault counter confirms repeated behavior before this timestamp.

The seller’s statement conflicts with the recorded diagnostic data.

Statement 3

Colin:
“Unfortunately, the sporadic issue happened after sale has been done hence why we have tried reaching out to help rectify the situation.”

Diagnostic Record:
The July 18 stored entry is the oldest time ODIS could display the fault.
The frequency counter confirms ongoing failures before that.

The phrasing “happened after sale” is not supported by any log entry.

Statement 4

Colin:
“As mentioned prior, the vehicle was properly inspected as per Manitoba safety and during that everything that was checked passed.”

Diagnostic Record:
At the time of inspection, the selector lever Park Position system had already accumulated 135 recorded fault events.
Electrical faults do not disappear during a safety inspection.

The documented data contradicts the assertion that the inspection described the true state of the system.

Statement 5

Colin:
“We are recognizing that things can happen that are out of anyone’s control even if proper safety inspection has been followed.”

Diagnostic Record:
The Park Position signal fault was active and confirmed two months before delivery.

This is not a post sale or spontaneous fault based on the logs.

Closing Summary

The diagnostic log provides clear evidence that the Park Position detection fault was active well before the sale date. The dealership’s written statements do not align with the recorded timestamps, fault counters, or mileage logs.

All information presented here is factual, directly extracted from the ODIS report, and matched against verbatim written communication from the seller.
