My 05 XJ8VP was attacked by a squirrel a few weeks ago! It ate the bundle of wires on the left side of the engine (next to the oil filler). I soldered the wires back together, BUT now, there are numerous error messages displayed on the cluster such as traction, airbag, engine wiring, parking brake, etc. even though the car does start up/idle perfectly (with the error messages). The car will not rev above 5 mph! I cannot get into the engine ecu with my iSoft scan tool which I understand is a known flaw in the software.

Before having the car towed to the dealer, IS it likely the car needs a complete reset with the Jag dealer software? It did start up the morning after the squirrel ate the wiring, but ran very poorly. Again, the car now starts perfectly and idles perfectly with the wiring repair.

Any help much appreciated! Frustrated because the car was awesome before.

You are probably missing additional wires or your solder repair didn't take.

Pulling and listing the codes you have is the first step to figuring out what is wrong. Most likely it won't need a reset. There are most likely additional modules or sensors that can't talk to the rest of the system.
