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
:1zhelp: :beerchug:

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…:o

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

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 !! :biglaugh:

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

Yes, I would suggest you start by fitting a genuine VAG VW dealer supplied exchange Air Mass Meter purchased from your VW dealer or a trade TPS, the part number is 06A 906 461 BX and they cost just under £100. DO NOT buy one from anywhere else, not fleaBay, an aftermarket supplier or anyone, just from VW.
