I have had a few of these in now where the vehicle immobilises itself and requires the ecu matching to the Becm.

One of the cars came from Norfolk and had never been a problem untill he parked it outside his friends house in Barnsley, It was parked within a few hundred yards of a Mobile phone mast and he left it there 2 nights and the indicators stuck on both nights and immobilised itself.

The next one was bought by a pub landlord who parked it in the Pub car park And funnily enough in the same car park was a mobile phone mast, If he parked the vehicle just down the road, it never caused a problem, but he kept risking it and parked it in the car park, But after about 10 times of having to have the vehicle recovered and the immobiliser reset, He decided to sell it.

I asked the dealers if there had been a recall, but they said that they didn't know anything about the problem. A Modified ariel was available but they couldn't say what the reason for fitting the modified ariel was.

I also tried an Autodiagnos on the first one that we did and it failed to reset the immobiliser, So the T4 including the trolley went in the back of the van and the job was completed in a few minutes.

Another case of using the correct tool for the job. Most Aftermarket sacanners are just a waste of time, space and money.
