Title: 00537 - Lambda (Oxygen Sensor) Regulation: Lower Limit
Post by: ryanbrook on 17 January 2013, 18:47
got this code when doing a diagnostics.

I have had a look on ross-tech and found this:

Possible Causes
Activated Charcoal Filter Solenoid Valve 1 (N80) leaking/sticking
Injector faulty (not closing completely)
Fuel Pressure Regulator faulty

Possible Solutions
Check/Replace Activated Charcoal Filter Solenoid Valve 1 (N80)
Check/Replace/Clean Injector(s)
Check Fuel Pressure Regulator

Right i know i could go ahead and change everthing, but just wondering if you guys know what the most likely culprit is?

Cheers
