Do I have to pay for diagnostic work on my car?
An extended warranty provider may not cover the costs of diagnostic work and investigation or, if it does, it may not pay straight away as the warranty company will need to establish if the claim falls within the warranty’s terms and conditions.

As such, you will usually be responsible for giving the repairer permission to start any exploratory, investigative or dismantling work and for paying the costs involved if this proves that the warranty company are not liable for the claim.

Some extended warranty policies will pay any reasonable costs of investigations if they are part of a valid and authorised claim – however, you will need to refer to your policy’s terms and conditions for full details of your coverage.
