Clean the throttle body.

If you have to turn it - then turn it in normal running direction (not backwards).

Narrow body cars need: Front 50-52 mm offset Rear 65 mm offset

There is no 996 TT manual there last time I looked. And, most of the manuals there are woefully out of date and missing important supplements.

Try 8362 or 8360

That is strange. You might want to try and call the Becker folks. 201-961-1399

Please don't take any offense to this- but did you even read my problem before just habitually posting the link? I have the radio code and I have read the FAQ- it does not cover this at all. I have also searched "not accepting radio code" and have not found this same problem mentioned anywhere. My radio does not say "wait" but I have tried leaving the key and radio on for 1 hour anyway with no luck. The code worked just fine last year when you gave it to me. It is not accepting it now. I can enter it and it goes right back to the first digit like it would if you had the incorrect code. I can also enter an incorrect code as many times as I want and it never says "wait" like it would with the wrong code before. Anyone ever seen this? Did you do as the FAQ suggests and verify the radio serial number? Does that part work?

Some of the older 993's do not have much information to look at. Very early days of OBD. What are the fault code(s)?

Try 1178 or 1176 I tried the two codes, more than once, after three tries it goes into the wait mode. any other code suggestions? Thanks Lost Radio Code - FAQ, PLEASE READ THIS FIRST

Does your switch look like the one in this post? (more shape than color) http://www.renntech.org/forums/index.php?s...st&p=101751

Why take it to the dealer - Autozone and some other parts stores will let you read the codes for free. Without the codes everything is a guess. You could wait and see if they come back (if they are off now then it is safe to drive). if and when they do come back - read the fault codes out and report them here.

What DME are you using? and did you re-program it?

Fault code(s)? You need to get the cars fault codes read.

Try 5505 0r 5503

Try 1178 or 1176

Could be that the clutch is about gone.

I have recently acquired a 2001 911 and bought the Durametric Diagnostic Kit. It reports a P0650 fault code. Does "open circuit" mean that the engine warning light has been disconnected ? Please advise Possibly. Check the bulb, then the wiring.

Yes, you will have to pry the clamp off.

Try 4964 or 4962

Try 2322 or 2320

Try 8777 or 8775

Disconnect the vent line for the oil separator at the intake distributor. Undo all hose clamps (4 ea.) at the intake distributor and push the rubber sleeves to the side. Pull out intake distributor to the rear. 5. Pullback protective cap on the starter cable and undo cable terminal 30 (M8)and terminal 50 (M6)at the starter. 6. Undo the upper fastening screw.
