Hi folks i bought my 2007 a3 8p 2.0tdi bkd a few weeks ago it had a damaged fuel tank so I've replaced that and have gone to start it and still won't start and has come with oil pressure light after turning it over, iv dropped the sump to see what pump I have to see if it was the drive pin and my pump doesn't have one so am I right in thinking new oil pump? Iv attached a image of what my pump looks like
