VAGCOM Fault codes query


Registered User
Hi Guys,

I've got an A3 1.8T and have recently been throwing up some fault codes.
16486/P0102/000258 - Mass Air Flow (MAF) (G70): Signal too Low
17544/P1136/004406 - Fuel Trim: Bank 1 (Add): System too Lean

both probably because defective MAF??? thoughts? (car has done 93k miles). Easy to rectify/fix?

17055/P0671/001649 - Cylinder 1 Glow Plug Circuit (Q10): Electrical Fault
I thought only diesel engines had glow plugs? am i being really dense or is there something else i should check out?

Any advice would be great, cheers
