Engine cutting out while driving - VAG COM codes

Hi all,

I was driving central London last week, when whilst in heavy traffic, my engine decided to go (1999 Bora 2.0 8v). Did it to me once on the strand then again - after bump starting it, on victoria embankment. For those of you who don't know the roads - it wasn't much fun. It annoyed plenty of people.

Anyway, finally got round to scanning with VAG COM today (apologies if this is in the wrong area of the forum)

I got these results:

Chassis Type: 1J - VW G/J/B Mk4

Scan: 01,02,03,08,16,15,17,19,22,35,46,56


Address 01: Engine

Controller: 06A 906 018 EF

Component: 2.0l R4/2V MOTR HS V05

Coding: 00031

Shop #: WSC 00227

5 Faults Found:

16684 - Random/Multiple Cylinder Misfire Detected

P0300 - 35-10 - - - Intermittent

16685 - Shareware Version. To Decode all DTCs

P0301 - 35-10 - Please Register/Activate - Intermittent

I'm thinking coil packs? Any ideas?

Any help would be great,

A faulty coil pack wouldn't make it cut out all together,if it was just one cylinder it would show as a simple misfire and it would tell you which cylinder.You need to clear all the codes then scan it again when the engine cuts out again and not several hours later.

I'm guessing maybe crank sensor which is easy to replace,also Google those other fault codes to see what they mean.

Thanks Chris. It seems it is an engine speed sensor fault, which is a real pain as I only replaced it a few months back - but at least its a relatively cheap and easy fix. Do you know if the genuine part is made by Bosch?

It's only cylinder one misfiring - but I think coil pack is a safe bet for that at least, what do you think?

Just to check, 'engine speed sensor' and 'crank sensor' refer to the same thing?

Is yours individual coil packs (one for each cylinder) or just one for all four cylinders?

Crank and engine speed sensors which are the same thing aren't common to go but also aren't all that rare to fail but are fairly unlikely to fail at such close intervals,but if you put a cheapie in before then get an OEM one which I think are made by Bosch.

The lack of a crank sensor signal or at least one that is breaking down could explain the multiple misfires which will be the effect rather than the cause of these problems as it supplies the timing signal for when each cylinder gets it's spark.
