Scan codes?

[Choongmu]

Hi got one of these today and i can say that for the money, it works very easily and has already saved me £40 for a diagnostic from an auto electrician.

http://cgi.ebay.co.uk/047-U281-VAG-VW-Audi-Seat-Skoda-CAN-Fault-Code-Reader_W0QQitemZ320501005503QQcmdZViewItemQQptZUK_Diagnostic_Tools_Equipment?hash=item4a9f593cbf

Anyway its thrown up the following codes:

16486 - mass or volume air flow circuit low input

16684 - random misfire detected any cylinder

16687 - cylinder 3 misfire detected

16514 - 02 sensor circuit malfunction bank 1 sensor 1

17545

17705

so im guessing (hoping) that the 2nd and 3rd codes are linked and a coil pack?

I cant find the 17545 but from a search on here it seems that maybe a throttle body clean and check of the pipes might sort this and the 17705 codes. Does anyone have any ideas about the other 2. Do you think that i will need to replace the MAF and 02 sensor? I have a MAF cleaner so will probably try this first when sorting the throttle body etc out. But do these codes mean a knackered sensor or just a consequence of the other things malfunctioning?

If the 02 sensor does need replacing can you tell me where it is and if its something a semi competent person can do?

For a bit of info its running only slightly rough, there is a hesitant on idle and initial acceleration but no problem boosting or steady driving.

thanks in advance

Cheers for that, a very useful site. have reset the light with the diagnostic tool i bought and took it out for a drive today.......sods law light has stayed off!!!! Think i'll get the coil pack replaced anyway as its only £30 and then take it from there, though it seems that the 02 sensor needs replacing as its linked to that 17545 code.

Anyone know where the 02 sensor is located?

Unless I'm wrong that would be your Lambda sensor in the exhaust system!
