Hi, my car was overheating and I took it to the garage and they found some major problem (with head gasket) with it. They charged me £1365 (including all other parts normally replaced when head gasket is replaced and labour. warranty company agreed to pay only £450 for head gasket alone ). I paid it and took the car from the garage in the morning and in the night I got the engine warning lights in my car again. I was planning to take it back to the garage next day morning. but my car was stolen in the night and recovered in the morning and I took it back to the garage again. Now they think something else is also wrong with my car (engine block). They thought the problem was with head gasket which they had replaced and thought the problem will go away after that and didn’t check if something else is also wrong (I am not sure if they have actually test driven my car). When I ask them, they are saying no garage strips the whole engine down to see if there are any other problems, because it costs them lot of money. Now I am not sure whether the garage is at fault or not and what options do I have to solve this problem. If I go to warranty company again, I am not sure what they are going to say. I have a maximum limit on the warranty pay, so I will have to shell out even more if I decide to go ahead with this repair. I can make a complaint about the garage (for that I need to check if they are at fault), but I don’t want to get into a lengthy legal battle if there is an easier alternate solution. Is it not possible to check what the problems are before carrying out the repair? is it a trail and error method? like fix something, drive and if it problem occurs again, check it again. surely there must be a better way to diagnose the problem? This issue is causing lot of stress to me, Please help. Thanks in advance.
