I have been having a little bit of bother with my 06 ST.

I recently fitted a dump valve to the car, it worked fine but i discovered a hole in one of the pipes coming off the intercooler, so i bought some samco and replaced all of the turbo hoses.

After fitting i went to start my car and it seem'd like the battery had died. so i put it on a jumper pack and got it started. drove round for an hour to give the battery a charge. got the car home, quick shower, jumped back in my car, turned the key and nothing, just got that annoying clicking sound. tried to jump it off my mums car and still nothing.

My ESP system fault light came on on the way home.

I'm thinking the battery could be shaged, but after reading a few things on here, i think it could be the alternator. If it is the alternator I could get it replaced on warranty as i took out the extended warranty. but with the car now fitted with samco, dump valve and an air filter. do you think this would void the warranty?

Thank you in advance
