Help - My Cayman will not start. Electrical issue I think!!

[mightyfine79]

Since my 09 Cayman went in for a Major Service at an OCP I feel it has not being the same car. It has only done 19.5K miles. To me it does not pick up like it use to or stick to the road like it did. (It also came back with a few scratches for which they agreed to give me a Free Machine Polish, hearing some horror stories might give that a swerve!!) Over the last two months however the fuel gauge has completely packed up, the windows don't often go back up when the doors are shut and the clock constantly resets with every ignition. Had booked it in to be seen on Thursday but tonight it will not start at all. The bizarre thing is that now the radio just randomly comes on without the key even in the ignition or anyone been in the car. The other half is totally freaked out!!

Is this going to be a pricey fix it is still under warranty.

Thanking you in anticipation

Thank-you for the help. Typical that this is the one week I don't have access to my other half's car as she is away on holiday and being a Bank Holiday it confuses the issue further. Went in to Halfords and spent £115 on the best battery they had got it home put it in, and the car started first time. The only thing that does not seem to work is the petrol gauge now. I assume that would be an MOT failure so I would have to get it fixed at some point?

If I take it in to the OPC will they insist on changing the battery to an approved one? I own the car on a PCP deal so am not bothered about the longevity of the battery just need it to last a couple more years and the only thing left I need to do is get it minor serviced next year.

Thank-you once again for the help.
