This lovely jaguar XF R visited our workshop last year for a tailgate loom repair (the common rear camara not working) and recently came back as the no warning chimes were apparent even though the messages would appear in the MFD on the instrument cluster.
First we ran JLR SDD to do a full OEM main dealer diagnostic test plan of the vehicle. This diagnostic test plan returned no faults. So we started to search our heads, we ran another few tests on the cluster including the speaker activation to find the speaker was not making any audible sound.
Next we removed the instrument cluster and checked the speaker and soldered connections and this looked A okay. We then removed the speaker and powered it externally to ensure the speaker was the fault rather than a network of CANBUS error.
As the speaker was not making any sound we changed the speaker for a second hand one we had in stock. Total turn around of 3 hours to diagnose and repair.
All in all a fairly straightforward job for a relatively common issue on the jaguar XF amd landrover discovery.
We are based in Saxmundham Suffolk but we are often able to provide a mobile service across Suffolk, Essex and Norfolk depending on the service required.
