logray,

Is there a diagram/picture somewhere that points out where these engine elements are?

I'm new to my 996 and wouldn't want to remove the wrong bit (I'm not saying I don't know what engine parts are, it's just that I'm not familiar with the Porsche names).

My throttle is rather flat until half way - I may give the cleaning a try.

Danny

For a few seconds after I start to move off, I get an annoying beep.

Previous owner says there is/was a tracker fitted, indeed there is a smartcard (credit card) thing in the glove box.

Since the tracker isn't used, does anyone know how I can prevent it from beeping?

Don't wish to doubt your abilities but you're sure it's a cap?

You absolutely should question my response, it probably is a resistor. I didn't look very hard (bad light, old eyes and crappy magnifier) and I'm not at all familiar with smt parts. :)

Some of the other caps are buff coloured and have no marking. If it's black and says 104, I would have guessed it's a 100K resistor.

My son the photographer has finally relented to pull out a pile of expensive equipment to take a photo. I can now actually see the color!

Wonderful. That's definately a resistor. Thanks for the efforts.

I find it just amazing that one can ask such an esoteric question and fiind the answer within days - I'm now hooked on this site.

My 996 has 18 inch wheels. I have a 'spare' set of 17 inch wheels with worn out rubber.

Is it allowable/sensible/legal to migrate back to 17 inch wheels one axle at a time?

Tyres for the 17s are about half the price of the 18s and I presume the ride is a little softer too.

Danny

A new battery and it works - thanks again for all your help.

btw I fitted a CR2032 rather than a CR2025 which is the same diameter and voltage but more life. Fits even though a bit thicker.

CR2032 is the correct battery for mine.

Is that with or without the resistor?

I had trouble with one of my remotes once, and it was a battery problem.

New DL2032 didn't work. CR2032 did.

Bill

That's with the added resistor.

I believe CR and DL batteries are the same. DL is duracells name for their cell.

I wonder if your problem was one of the remote 'locking up' as described in posts and that replacing the batt fixed it.

Danny

The smells can drive you crazy on a 996. I came from a deadly quiet non-smell 740i, the 996 was like "what the %$^*!! smells. Had the car inspected and it was all perfect. Watch your coolant leve for sure, but eventually I got used to it.

I''m very new to my 996, it smells like burning rubber - previous owner says it has always smelled like that. Is that what you describe?

Danny

I thought a US 1999 996 has a one button remote, unless it is a ROW car.

Anyway, a mechanic gave me a dead remote to play around with it, so I do not know for sure if it is from a 986 or 986 or what year. It is a 2 button remote. It has a colored crest so I'm going to guess it is from a 2002-2004 996.

Does not look like yours.

Mine (2002) looks like that one.

Bill

The car is European, so may use a different frequency to your 'foreign' US ones and therefore a different pcb.

I tried fitting a 100K resistor last night, but sadly it made no difference.

The problem is this:

I can unlock the car if I press the button on the pcb without the pcb fitted to the key fob - it doesn't work every press, but within three it usually works.

When I fit the pcb into the fob it never works, The led still flashes, but no unlocking. Strange isn't it.

According to the last owner, the push button dropped off, so he resoldered it and it worked for a while, then became progressively worse.

It's not that I'm touching the components when I press the button out of the fob, as It still works with insulation tape covering all but the button.

It's as if the transmission power is very weak, so weak it can't transmit through the plastic of the fob, sounds unlikely to me.

Maybe holding the pcb alters the characteristics in some way.

The battery is a good 3V by the way.

I wonder if Eric is still out there and could send me a picture of his pcb.

Thanks for your time, everyone.

Danny

Having said all that, it does sound like classic battery failure. The battery reads 3.01 volts, when I press the button it drops to around 2.8.

I'll get a new battery and try that.

What year car is that remote from? The ckt board in mine has almost

nothing on the pushbutton side. 99% of the circuitry is under the battery

holder.

This is a 1999 996 cab, so one button is for the hard top.

Danny

Danny, mine's got a 104 cap there.

Eric

Eric, that's great. I'll give it a try.

Don't wish to doubt your abilities but you're sure it's a cap?

Some of the other caps are buff coloured and have no marking. If it's black and says 104, I would have guessed it's a 100K resistor.

The 4Gt marking on the transsistor indicates that its a BC860 (PNP general purpose) so the missing component is across the emmitor and base. It's just that I can't think why one would place a cap there - also 104 for a cap would be 100nF and in a 0402 package that is a high value.

Any confirmation would be appreciated. Rather shocked by the response actually.

Danny

I have a rather odd request. My two-button remote key fob isn't working well. In the past it has been repaired since one of the buttons fell off! - probably due to the battery getting low and someone pressing harder and harder.

Looking at the printed circuit board under an eyeglass, I can see that one of the little surface mount components is missing. I can see that it was once there but has dropped off, maybe when it was repaired.

Now, I'm an electronics engineer so I can fix it of I know what the component was.

I wonder if anyone is prepared to take a close-up photo of the pcb inside their fob - the side with the push button switches - from that I should be able to determine if the component was a resistor or capacitor, and from the tiny number printed on the top of the component, what the component value was.

The attached file shows a close up of my pcb with the missing part.

Your help would be greatly appreciated.
