[s-cars] Check Engine Light etc

[James Murray (LMC)]

Hi Aaron,

Sounds like your CPS is on it's way out, same thing happened to me. It will
gradually get worse. Some answers:

1)	Yes, mine did the same thing, might be heat related or a connection.
2)	Yes the codes are stored even if intermittent, you could have codes
from the previous owner too.
3)	Yes you can remove power to erase the code, ECU will re-learn. Or go
to a garage with a VAG and have them erase the codes.
4)	Symptoms are Hard start or no start at all, you'll find out the next
time you take the car out and the light come on and you turn the car
off...better hope your not in a rush to get home.
5)	We are all just plain nuts...a lot of newer cars have the same
technology, take a look here: http://www.obdii.com/obdii.html

	Hi all
	Last night my check engine light on our 1995.5 S6 Avant came on as
my
	wife was driving home.
	After dinner I went out for a drive and the light went out.
	Everything seemed fine - no unusual noise or behavoirs - smooth
idle.
	I went ahead and checked the fault codes per the instructions on the
	auto tech site.
	I got one fault code  - 2113 (cam position sensor or distributor
	alignment ?)
	I have a few questions -
	1) If the check engine light comes on but then goes out on its own,
does
	this mean the faulty device is intermittent?

	2) Are all fault codes stored regardless weather or not a device is
	currently faulty.  Would a intermittent device produce a fault code
	which would remain stored even if the device is not currently faulty
and
	check engine light is off. (As I have only owned this cas a few
weeks, I
	am not sure if there were any stored codes from the previous owner)

	3) Should I erase the codes buy removing fuse on ECU and wait and
see if
	any codes(s) come up again?  What about "learned ignition timing and
	adaptive fuel mixtures"  - will these reset themselves after a few
	miles?

	4) What are symptoms of code 2113?

	5) This self diagnosis is amazing! Do other modern cars have such a
	system where the owner can trace a fault without fancy equipment or
is
	this why we become Audi nuts?

	Thanks for all your wisdom
