Help! Rough running from cold start 2007 v8 vantage

[stanwan]

I’ve had a couple of isolated incidents from a cold start - hesitation and lumpy running culminating in a red triangle warning light and urgent emission service warning.

Normal running seems to resume after switching the car off and on again. I picked up one of those Aldi OBD tools rectently and it gave codes of p02010 and p2100.

Today I erased the codes and once I arrived home, I connected up the code reader and ended up with around 17 different codes from. MAF to injector and an obscure C code too.

My dealer reckoned it was running perfectly when serviced a month ago!

Does the vantage spew these codes out constantly? Anyone Got any ideas before I take it back?

Possibly - it did go flat around a month ago but seems to start the car without issue after it spent a week on the battery conditioner.

Its still the original battery - might be due a replacement anyway!
