Hello,
Just thought I would provide an update to the forum as there is nothing worse than a plea for help and then not knowing the journey or endgame...
I’m continuing to experience ongoing mechanical issues with the vehicle.
A self-conducted OBD2 diagnostic scan revealed the following error codes:
- U2101(56) – CAN data bus – ECM incorrectly programmed
- U0028(87) – Vehicle Area Network VAN data bus A
- B1C45(67) – Body Control Module/Gateway Module
- U0402(00) – Transmission Control Unit
A subsequent diagnostic via a Jag Assist roadside assistance service confirmed similar codes:
- U0402 – CAN message: Transmission control unit malfunction
- U2101 – Control Unit: Configuration calibration not performed
Following advice from the
seller dealership, the vehicle was taken to an authorised Jaguar service centre on 01/04/25. Their diagnostic identified
P245F-2A.
See inspection notes.
Interestingly – this shows as “Diesel” Particulate Filter on other OBD scanners and web-searches…
The service team advised that further investigation is required, which will probably involve stripping down the engine to determine whether the fault lies with a sensor (there is 2) or a pipe. While the vehicle is covered under its Jaguar Approved Used Warranty, the earliest date for further diagnostic work is 09/04/25, and unfortunately, there was no courtesy car is available. Upon leaving the
repairer dealership having confirmed the above date for diagnostic/repair, the “Limp Mode” issue occurred 3 more times on the journey back home.
I’m still considering the 30-day Vehicle Rejection route (but its going to be close [13/04]) and changing circumstances (as well as the current dependability of the vehicle) do not bode well to a 6hr+ drive back down to Northampton and then there is the costs of the subsequent flight, train and then taxi back home - just to shop around all over again.
To solve the courtesy car issue, at the request of the
selling dealership, I contacted Jaguar Assist again and was told they couldn’t help in this case. Although I had followed their roadside assistance process (as advised by the seller dealership), Jag Assist said that now that because the car is booked in for repairs, it’s the
repairer dealership’s responsibility to provide a courtesy car - if one is available.
I explained that they had already told me no courtesy cars are available until May ‘25.
Jag Assist then suggested I ask the
repairer dealership to contact them directly and request a courtesy car through their internal VOR (Vehicle Off-Road) service, which uses local third-party providers.
I followed this up with the
repairer dealership, and they said they’ll pass the message to their Service Team on Monday (they’re currently closed for the weekend).
Apparently the
seller dealership will also contact me on Monday to discuss the particulars of the Vehicle rejection process for clarity.
