The big problem here is that fitting a Remote start unit to any Thatcham approved product will void the system's approval. “Cat 1” security systems are tested as a complete product and then given an evaluation number by Thatcham based on the products proposed usage.
In their view, adding any other product at a later date, which interacts directly with the approved security system or by-passes any of its circuits, can be looked upon as a modification to the system that was tested and could void the approval on that particular installation.
To be fair, you wouldn’t expect a Category 1 product to still gain you the same recognition by your insurance company if the secure, passively arming immobilisation circuits were by passed and this is exactly what these products do to allow the engine to run.
Adding additional products such as turbo timers and remote start devices are seen by Thatcham (the UK insurance industry’s test centre) to compromise security in the same way, as these systems usually have to by-pass the security system's immobilisation circuits to allow the engine to run. In theory a turbo timer need not cause a problem provided that it is not connected to or by-passes the existing immobilisation wiring, however the immobiliser would kick in 30 seconds after the ignition was turned off (a Thatcham requirement), limiting the turbo timer to 30 seconds.
There are also a couple of other points for you to consider:
Due to the UK insurance industrys requirements (and EU legislation) a turbo timer or remote start unit is unlikely to have been designed with the UK market in mind and so is unlikely to have been tested to EU 95/54 (- electrical legislation) and will not bear an “e” mark to show that the product has been tested and is fit for the automotive environment.
In addition, leaving a vehicle unattended in a public place with the engine running is also an offence in the UK, contravening the Construction and Use regulations.
If you don’t mention the mods to your insurance company, or the broker does not understand the implications of the modifications, then they will still be happy to take your money, but few vehicles with the standard system are stolen without the keys, so if an enlightened insurance inspector were to detect the modification it could invalidate a policy and save them paying out.
