Hi All,

I've been getting the ASR dashboard warning light coming on intermittently on my mk1 Octy vRS.

Plugging in a Ross-Tech VAG cable gives me the following info but I'm not sure where to go from here or how serious these codes are. I'd appreciate any advice. Thanks.

UPDATE:

I note the Ross-Tech site states 16486 could lead to a loss of power!

They state the following about code 01314:

Engine Control Module stored a Code which influences other Control Modules Functionality.

To clear this Fault Code you will need to correct the Problem in the Engine Control Module first.

16486/P0102/000258 - Mass Air Flow (MAF) (G70): Signal too Low

Possible Symptoms

• Probably no serious malfunctions
• Loss of power

Possible Causes

• Wiring and/or connections (short circuit?)
• Mass Air Flow (MAF) (G70) defective

Possible Solutions

• Check wiring and connections
• Check / Replace Mass Air Flow (MAF) (G70)

Special Notes

• In MY 1995-2002 (?) in Europe at VW-diesel-cars G70 had the bad reputation of slowly losing his performance, causing loss of power. It's not a matter of defective or breaking down, but it is filthy / dirty (not easy to clean). You can check functionality by making a log in [01-engine], [meas.blocks-08], group 003 (3e gear, full throttle, from 1700-4000rpm)

01314 - Engine Control Module

• 01314 - Engine Control Module: Check DTC Memory
• Possible Causes
• Fault(s) stored in Engine Control Module

Possible Solutions

• Check Engine Control Module for Fault Codes

Special Notes

• Engine Control Module stored a Code which influences other Control Modules Functionality.
• To clear this Fault Code you will need to correct the Problem in the Engine Control Module first.
