Aaaaarh esp+engine light 1.6

[jahilton2002]

Hi guys,

thought i'd the pros about a prob on the mrs Bug,

popped over from the mk6 goof section so this is my first posting the new beetle threads. Anyway... to the bug mobile;
I’ve just fitted a 3rd mass meter this week, so I guess it’s something else lol. The car revs really erratically at the lights and from cold, seems to be drinking allot of fuel, 300miles to a tank my Honda (yes I know) 2.3 auto accord does 364miles).
I have a basic diag machine codes are;
Engine
17549
16486
16556
Abs
01314
I’ve been told to check pipes for splits...... but I would know which pipes to check, any pointers
Just nope it’s not both lambda or the car

Which year and engine code?

Which year and engine code?

its a x-plate 2000 iirc.... where can i find the engine code?

thx for your reply and help

[Crasher]

I don’t do text speak, I had to Google iirc to know what it was an acronym for…

PM me your reg number and I will tell you the engine code.

[jahilton2002]

sorry, thx for the reply i'll pm you now.

As I'm on nights and bored I did some research. They seem to point towards a Mass Air Flow sensor fault. Is yours firmly connected and not contaminated.

Check all pipework after the air filter housing for splits that would cause a vacuum leak in the inlet.

If you check for faults as recommended in the information below and have no success it is likely to be the MAF itself. I would wait for Crasher to respond before spending any pennies !!

Code 01314 can probably wait until the other codes are investigated and cleared.

17549/P1141/004417 - Load Calculation Cross Check: Implausible Value
Possible Causes

• Mass Air Flow Sensor (G70) OR Manifold Pressure Sensor (G71) faulty
• Vacuum Lines faulty

Possible Solutions

• Check Mass Air Flow Sensor (G70) OR Manifold Pressure Sensor (G71)
• Check Vacuum Lines
• Check Engine Operating Conditions => Meas. Blocks

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)

16556/P0172 - System Too Rich, Bank 1
Possible Symptoms

• Irregular behaviour

Possible Causes

• Fuel system
• Excessive fuel pressure
• Leaking or contaminated fuel injectors
• Leaking fuel pressure regulator
• Low fuel pressure or running out of fuel
• Vapor recovery system
• Air leaks after the MAF
• Vacuum leaks
• Improper seated engine oil dipstick
• Stuck EGR valve
• Oil overfill
• Cam timing
• Cylinder compression
• Exhaust leaks before or near HO2Ss.

01314 - Engine Control Module: No Communications
Possible Causes

• CAN-Databus Wiring/Connectors from/to Engine Control Module faulty
• Fault(s) stored in Engine Control Module

Possible Solutions

• Check CAN-Databus Wiring/Connectors from/to Engine Control Module
• Check Measuring Value Blocks (MVB)
  
  • Usually Measuring Value Blocks (MVB) 125+ show the current Communication Status

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
