After consulting with a lady on the phone and being reassured that your bulbs would work perfectly in my car. so I take my car to the garage to get my bulbs fitted and amazingly there we go two warning lights on my dash so I call you back and get some one who does not seem to sure so they go to ask for help and I am now told that this is very common on audi and I need another part. My question is this why would you not give all the information to me on my first call as I now have to pay again to either fit your modified part or put it back to a standard part. you have given me no information regarding weather the bulb or modifications will render my bulb warning system useless. I don't fell that you have done a good job looking after this customer I now have to wait for these parts another trip to the garage another bill from the garage this could have been sorted first time round
