So I did give in and buy a Ross Tech Micro-CAN for £155. I am getting my head around it, and reading around to make sure I maximise its features. For starters, a bit of help on these detailed fault codes would be fantastic. (Edited to remove ones which were okay, my questions in bulleted italics, instructions from Ross Tech wiki in bold italics)

• Wiki has subsections for 'Short to Plus' and 'Electrical Fault in Circuit'; not for 'Intermittent'. Anything I can do about this or ignore since it's intermittent?

• Intermittent codes are often stored during low outside temperature when the battery capacity goes down and may be ignored: it's not terrible cold here in Cambridge. Blame the weather or get a new battery?

• It seems these four appear like a syndrome. RossTech says: the most common cause for this is the Ignition Switch (Electrical Portion). Do I need to replace the ignition switch?

As ever, thank you so very much!

 

I get the last one periodically, especially when it's cold. The sensor is in the roof near the rear view mirror, behind the two grills. My alarm still works correctly so I wouldn't worry too much.

Thank you so very much, thats one I can rule out now. Which sensor is that...the rain/light for the wipers? Or the IR connected to the security alarm?

It's the alarm sensors, I think they're ultrasonic.

This might help with the ultrasonics: http://www.briskoda.net/forums/topic/128706-anti-theft-alarm-systeminterior-monitor-error/#entry1633042

At least removing, cleaning with compressed air and refitting helped a friends pre-fl :-)

oooh, i will do that!

I know what I'll be doing this weekend!

turbo - sticky vanes. vacuum hose leaks. damaged turbo. it is like needle in hay stack. unless, I see I can't tell. It looks like standard +-400mbar range was triggered. usually sticky vanes in turbo or leak

 

air flap - looks like dead servo in clima

air flap - looks like dead servo in clima

 

I totally understand, it's hard to diagnose remotely! Would I be able to use any more of VCDS magic to narrow down the list of causes? Any particular parameters to log then put on a graph to help?

 

ill search here to see how people sorted sticky vanes

 

where are the vacuum hoses for me to check for leaks? I read somewhere about disconnecting one end and sticking a bicycle pump in one end to see if it holds pressure.....would that sound right?

 

damaged turbo....please dont tempt fate!

 

dead servo in climate control? Okay, Ill search on here and find a fix!

VCDS has got a function of controlling all active controllers. You don't need to blow out manually.

 

You can test N75.

 

Sticky vanes are simply to test. Warm up your car. then drive on flat road on third gear...let revs drop to 1500 and then flat out. Turbo starts to kick at around 1800 or 2000 if 1.4TDi. Or you can push it very hard with hard turbo use and vanes stick in no time

 

ETKA + VCDS and GOD is DJ

Thanks, Mike. I will run through what you have kindly advised and get back to you. I agree, clearing codes singularly will give me the learning experience I need.

MIke, I don't believe this!

 

I cleared the codes individually and only a new one showed up! (02390: i think i somehow activated footwell lights on VCDS coding....I'll retrace my steps and undo).

 

Given that you said the intermittent issues are down to low voltage and likely cold mornings, I'm sure part of the solution has been the new Bosch S5 I fitted last week after having to call the recovery in the morning for a jumpstart when my booster pack wasn't enough to get it going. (The battery was old anyway and end of life anyway).

 

I could have sworn I cleared codes and reran them before posting my original post in this thread. Although then, I used the 'clear all DTCs' option under the autoscan module and not individually through the control modules, as per your advice. I'm guessing they didn't clear properly for some reason and doing them individually is the way to go.

 

Resetting the HVAC flap also solved that. You mentioned they tend to become periodically sticky...is it easy to disassemble and give a thorough clean?

 

In terms of working out if sticky vanes is the turbo issue (it feels like there's a turbo lag), could you advise which blocks to measure continuously and plot on a graph? When I have time, I intend to follow the steps here: https://sites.google.com/site/1810martin/vcds-and-pd-tdi-engine-health-check

 

As ever, thank you very much!
