Thanks for the reply, tried resyncing with no luck. I'll give land rover a call tomorrow.

I had a similar problem on a motorbike a couple of years ago, felt like big transmission lash but turned out to be a fueling problem, ran fine up until high rev acceleration or quick throttle shut off. Re-jetted the carbs and it was fine afterwards, don't know if that helps at all.

For the past couple of months everytime i've tried to unlock my 90 with the fob the alarm sounds, whether i've locked it with the fob or the key. I'm hoping this isn't a main dealer only issue as it's a 6 hour round trip to my local dealer. If anyone else has had this problem, how did you sort it?
