2003 a3 2.0 fsi
wouldnt start last week,just had new timing chain and cam pos sensor fitted,starts o.k now but idle tickover is so low and lumpy it cuts out in traffic ie, when stopping at traffic lights e.t.c...
Had more work done,timing chain was out by half a tooth,also had a oil service
Now starts fine cold and ticks over perfect, but now struggles to start when warm and oil warning light comes on even though its had a new filter and oil!!
Pulling my hair out,any ideas folks?
