What sad lives some people lead!

Ah well, I'd not done that much mileage anyway. It's going in for a
service in the next few days anyway, so I'll ask them about sorting
it for me.

not sure what an ecu check costs out there but it might be worth a check.
Here in the UK its £30 ($50) by a third party test house. Had my sons
checked recently because of poor running, the check showed up a problem and
the repair cost £120 which included the £30 so it was better than the
dealership who quoted me £200 for a new ecu.

somehow I doubt yours has a problem, just from a battery change, it just
needs time to settle or even a nice long run out.

I'm in the UK also.

Going to take it into "All Audi" in Bristol (anyone had previous
experience of them?) I'm not paying the £80+ per hour rate at
the dealerships! Besides, in my experience, once a car is more
than about 10 years old, the dealerships know less about them than
the independents.

I've used All Audi for parts a few years ago, and was very
impressed, hopefully their service dept is as good.

Regardless, I'll give it a good run out tomorrow and see if
it settles.

cheers,

Matt.

I might have missed it, but did you say the Engine Check light (aka MIL) is
lit?

There's all kinds of folklore and outright voodoo about how to clear a MIL
indicator after a battery or ECU replacement, but normally, a 15 to 20 minute
driving loop including highway speeds, city speeds, full stops, idling time,
and one full engine run-stop-run cycle, will clear the MIL functions.

What may have happened is some part (eg: the MAF) is so far out of adaptation
range that the ECU cannot clear all of the bits to get the MIL to turn off.
There's a certain amount of variation that the adaptation process will allow,
and any part that's aged outside that range will fault the system until
replaced. You can step on the ECU and the MIL bits all you want with a
VAG-COM, for instance, but within a couple of days for sure that MIL will come
right back on.

On the up side, this is covered so thoroughly in the diagnostic bits that it
should be trivial for an Audi main line shop to diagnosis and fix, promptly...

Try this, start car, then turn off, then turn to possition 2 ( ignition on )
leave ignition on for 10 mins without starting car, sit in it of course
incase someone jumps in & steals car, I think the ecu will go through a
throttle body reset after a few miniutes if the engine is not started,
pitty audi did not warn owners of the pitfall of changing a batery in the
hand book,

There is no warning light or otherwise.

I haven't really been out for a good run since, just pottered around
town. I'll give it a good blast down some country roads tomorrow and
hopefully get it cleared. If not, I'll get the garage to take a look.

cheers for the advice.

Sorted at bl**dy last!

It has reset itself twice in the past few days (after > 100 miles!)
but once I've driven off, it returned to the problem above.

Today it reset itself twice on startup, but did as above again, however
I was in traffic and messing about I switched the engine off and just
let her roll downhill until I needed to drive off, then started the
engine whilst rolling and it has been fine ever since! Not sure if
that is a complete coincidence or what, but seems to have done
the trick.

Now all I need to get sorted is the blowing exhaust - I'm praying
that is isn't the cats, but it sounds like it's coming for that
area :-(

Matt.
