A cautionary tale;!..


Quite somewhile ago I posted here re my vintage Audi A6 and an a rough
idle problem.

From the start this would very rapidly start to "hunt" i.e. rev up to
say 1500 and down and then up and down and so on.

Several part's were changed and checked to no avail, so I just decided
to live with it as its an old motah and prolly not worth the cost of a
main dealer looking at it..

Now theres a new garage just started up locally specialising in German
cars and I thought I'd take it there just to see. One of the mech's said
"Idle valve", has it been changed yet?, yes said I months ago now.
Was it a gen Audi one asked he?, err dunno, sez I. Was it around 200
quid?, 'err No, more like 60 ish .. and off e-bay said the mech?, umm
yes Said I.


Have you got the original one still?. Yes, never throw anything away me.
OK says he, Heres what to do take the replacement one off and put the
old one back on but first dump a can of carb cleaner in it to flush out
all the crap that's prolly in there. If its still no go bring it back
and we'll look further.

OK sez I, then he said that they had a skip full of poor quality Chinese
and far eastern knock off parts over there, change them most days and
then fit Gen German ones. Just done that BMW over there with a Gen BM
alternator the replacement knock off unit was ****e..

So this afternoon did just what the man said and .. RESULT !!!

Its fine, ticks over right on the mark and runs that much better

A very Happy bunny.

Moral of the tale as above, be careful what you fit to your car;!!....

Pal has had problems with a pattern hot wire sensor for his old Rover.
Snag is new genuine ones are hard to come by. And of course much more
expensive.

The one part on my BMW which gives regular problems is the heater fan
speed controller. Not a simple resistor, but a SMPS. I'm on my 5th in 12
years. But it seems to make no difference if it's a genuine BMW part at 70
quid or a pattern one at less than half. They all last about 2-3 years.

Any idea what dies in it, or is it one solid lump of epxoy?
I wonder if it contains adequate protection from motor back-EMF?

Sadly, yes.

It seems to fail in a variety of ways. Usually you just lose speed control
so the fan runs at full speed - very noisy. Sometimes you can't even kill
it with the ignition switch, as the system allows the fan to be switched
on (along with an electric pump) to have heating without the engine
running. Until the coolant temp drops below a predetermined level. So the
only option is to pull the fuse.

The device is mounted in the heater intake air stream in an attempt to
keep it cool.
