**help Needed**

i did a vag-com reading this morning and it came out with 9 faults if i explain a bit about the car and then hopefully i can get an idea on whats wrong. the car has at the moment, a red flashing oil light which only came on after i did a engine flush and a oil/filter change using castrol 5w/40 fully synthetic oil, the reason i did the engine flush was due to loud tappets noise. secondly the "excess of pollution" light is on, i changed the coil plugs just before xmas? and thirdly the car has been sluggish starting, it ticks over a few times then starts, when before it would start straight away, after i did the vag-com reading i clicked on clear faluts or something like that and now the car wont start? my last question is when using vag-com can i change stuff like unlocking the doors, mine only unlocks the drivers side, no matter how many times i press unlock or resetting the ecu? atm i'm using the shareware version untill i buy the full version off ross tech.
here goes:
16487 - mass air flow sensor - signal too high
16717 - knock sensor 2 circ high input
16684 - random/multiple cylinder misfire
16688 - cylinder 4 misfire
16395 - camshaft pos. actuator circ. bank 2 malfunction
16705 - ign/distributor eng. speed inp circ range/performance
16706 - engine speed sensor
16622 - turbocharger boost sensor (a) circ high input
17863 - exhaust gas temp sensor

Your codes are incomplete. Each code consist of two lines of information. You're missing half of it.

Most of those codes are "Intermittent", meaning the fault condition that set the code did not exist at the time you performed the scan.

Do this:

* Select -> 01-Engine -> Fault Codes -> Clear Codes.
* Exit the Engine.
* Turn off the ignition for a bit.
* Try to start the engine.
* Select -> 01-Engine -> Fault Codes - Copy Codes, and post the codes you have then.

That way, any spurious codes will be gone, and we might have a chance to see if there's one that's preventing your engine from starting. Be aware however that there are many things which can prevent an engine from starting which the self-diagnostics in the ECU cannot pick up on.

ok dine that, it almost started then it din't, now it just ticks over, anyway thanks for your help and here is what the fault came up with.


VAG-COM Version: Release 409.1-US

Control Module Part Number: 1ML 906 032 A
Component and/or Version: 1.8l R4/5VT 0001
Software Coding: 10510
Work Shop Code: WSC 13113
Additional Info: VSSZZZ1MZ4R028252 SEZ7Z0C2183040
1 Fault Found:
16705 - Engine Speed Sensor (G28): Implausible Signal
P0321 - 35-00 - -

 

[Uwe@Ross-Tech]

The signal from the G28 sensor is the most important input to the ECU. Without it, the engine cannot start or run. I would look carefully at that sensor and the wiring between it an the ECU.
