Hi, I have jus bought an 2006 Audi a6 se 2.0tdi 138bhp
It has had oil pump, turbo, egr, t belt water pump intercooler redone an new ones an I have seen the receipts for work, test drove it an seemed dead on a. Drive home 100% and now today it's throwing up oil pressure warning, got diagnostics on it but it won't pick any codes up yet car showing fault,

Any help appreciated
Thanks
