Check engine light is coming up repeatedly and this is the third time its come up. First time its problem with Temperature sensor(thermostat) and it was replaced. Second time it was leak detection pump was replaced and now it complains regarding oxygen sensors, code P0130 and P0139. Appreciate any and every guidance to help resolve the issue.
Code p 0130 refers to the heated oxygen sensor (HO2S) 1 bank 1
code p 0139 refers to HO2S 2 bank 1 the HO2S is the ones in the exhaust manifold or pipe before the cat converter

as per vw, you need to check transmission oil level., not an easy thing to do. if transmission oil level ok (no dipstick on these by the way). it is a mecahnical fault.
SOURCE: my 2004 VW Golf had the check engine light on.
Go to any autozone store. Most will check your codes for free
SOURCE: check engine light comes on my Volkswagen Passat 2008
if you live near an autozone they will scan the codes for free
SOURCE: check engine light comes on even though i replaced the faulty camshaft senors
take it back to shop because.some of the 2.8 v6 passat had 2 cam sensors.one for right bank and one for left bank.if shop already replace them.they need to remove code from computer.

Hi,first thing your cambelt and tensioner should have been replaced 13k miles ago,it would pay you to replace the water pump at the same time as they are known for impellor failure = cooling system fault=P2181 code,hope this helps.
