biturbo.s4

Hi alan! Pulled out injectors and swapped them round to see if it was a faulty one. And nope, still showing cylinder one misfire detected. Cam lobes all look fine, normal wear and tear for 210k miles, and highly doubt that injector loom is the cause of a street full of white smoke for ten minutes!! Compression test will be the best bet, but dont have a diesel tester :)

Seatkid +1!! Loom looks ok, but should probably be first port of call. Although my thoughts are low compression not combusting the fuel properly. Engine does not use any water, but cant really rule out headgasket. Compression test would be ideal. Glow plug connector housing is snapped and upon whipping the plugs out, cylinder one looked very clean, where as the others looked heat worn (if that makes sense?) ;)

Sorted! Anyone fancya laugh? Wrong vagcom cable!! Itried my friends blue kkl cable and downloaded vcds lite and it scanned the ecu and all modules no problem! Although saying that at the same time it has a new battery on it, and i cleaned the earth points around the battery tray. I havent actually tried my old cable since getting this one to work! Anyway, quite happy now. And only two returning fault codes - 17569-manifold temp sensor (g72):open or short to plus p116135-00 16685-cylinder one misfire detected P0301 35-00 Also getting manifold pressure sensor but thats because its unplugged. Any ideas as to why the misfire, and i take it cylinder one is cambelt end?

Will try another cable... and then start checking the loom. Like i said pulling on loom behind abs controller made the aux water pump start coming on slowly... pulling on it more made it spin full speed, so maybe its around there?

Ok. Thanks for your help. Have tried connecting with engine running and get same problem. And battery voltage shows 13.9 i think.

Errr battery is a bit duff... surely its not that? It starts off the battery no probs.

Oh and neither does my elm237 bluetooth adaptor and android torque app connect.

Maybe, will try an older cable tomorrow and vcds lite. Although my cable works fine on my B5 S4 and my mates mk4 golf, neither of which are Can.

Ive no idea now! Loom checking time I think, although maybe an engine sensor is causing ecu to short? I noticed earlier that while playing with the loom behind abs pump the aux water pump started whirring a bit, and after tugging the loom a bit more it came to life. Think ill start there :46:

Righteo. Still naff all. Immobiliser box made no difference. And Full set of matched clocks, key, immo box and ecu didn't work either. I cant access ecu (no response from controller) and can only access other modules if ECU is unplugged. Still getting k1 open or short to ground on the test under options, every other time I test. Definitely stumped now! :46: And re the immobiliser box. It is a 6X box with a 7M sticker stuck over the top of it. Mine is obviously missing the sticker.

Not including programming - only cutting!

They are 160quid from vw for a new key!

Cant we all get along nicely? Lol :) Back on topicd(:P) do you reckon that could be the one?

Have just checked. With everything plugged in LED lights for two seconds after ignition is turned on. And flashes constantly when doors are locked. However if I unplug the IMMO box the light doesnt show when ignition is turned on, but flashes all the same with doors locked. And the Sharan does use Can wires to transfer messages, cut your loom open and check, or even easier check wiring diagrams. But you are right, it doesn't have CANBUS wires plugged into the diagnostic port like more modern vehicles. Anyway, more to the point, what do you reckon to this?? I think we may have solved it??

Will have a go with an earlier version of vagcom and report back. All wires in door gaitors are intact, I have checked these. From reading wiring diagrams it shows that the K-Line doesn't run direct to ECU, It runs through the immobiliser box, However it runs to clocks, and then from the clocks Can wires run to ecu. Although when i test vagcom it says CAN not ready?!? Where is the rubber grommet to the immobiliser lamp? Do these cars come with an immobiliser key led in the instrument cluster? Mine doesnt?
