hi am gonna sound stupid to those who know?
i have a S3 225BHP 2002 model. 2 months ago my car was running on 3 cylinders so i sent it in to the local garage he replaced the coil packs and spark plug the car was running fine for a day or 2. then the car started to splutter alot so i had i look found that the wires connecting to one of the coil packs was bear so i taped the up still no joy. i quessed that the bear wire might of broken the spark plug so i replaced all sparks but when i took out the plugs they was the same as the ones the garage put in. the car was great for a day or 2. and yes it started to splutter again. am wanting to know if there is a special type of plug to fit in the S3 and which ones are best. the plugs that keep going is the BOSCH SUPER 4 PLUG. can anyone help thanks. sorry for the assay:tocktock:
