Hi - My car hunts sometimes at idle - it idles at 600rpm (on the tacho), but every 10 seconds or so the idle speed increases (to about 800rpm) and then drops back to 600rpm. It doesn't do it all the time.... This is a C4 fitted with the electronic throttle. Any ideas?

Thanks,

Derek

Join Renntech and then do a search of the TSBs. There's a TSB for extending the keyless remote range but it requires a little work inside the car (you can do it....it ain't hard).

Thanks - How do I search for a TSB? Sorry - I am new to all this....

There are round black plastic dials on each end of the changer with an arrow. Make sure the arrows are pointing up.

The changer is made by Becker.

Thanks - one was and one wasn't - I can't imagine how it got this way - I haven't test driven the car to see whether it makes a difference - do the arrows align the shock absorbing direction?

Check vigorously around the expansion tank and see if there is any crusting. Feel underneath it with your hands. If there's any crusting, you either have a leak or need the updated coolant cap.

Smell and coolant topics have been making the rounds heavy this past week, eh?

Thanks - there is definitely no leak from the expansion tank - apparently this car is on its third tank, the latest being the upgraded version - does that make sense?

Yes it seems that the very small amounts of rubber from the rear tyres hit the hot silencers & give of a smell of burning rubber. Smell under the raer wheel arches is quite strong & apparently quite normal

Thanks - this does make sense - Makes me wonder how quickly the P Zero's are wearing away...

Does anyone know where I can buy a service manual for this car? Either genuine or aftermarket?

Thanks,

Derek

Hi - Does anyone have any exploded diagrams showing how to remove the front and rear bumpers on a 996?

It is a 1999 C4 model.

Thanks,

Derek

Hi - I have just bought a 1999 996 C4 - Even when driven lightly, it has a very mild 'hot engine' smell when I stop. It doesn't really smell like burnt oil (maybe burnt Mobil 1 smells a bit different) - to me it might smell a bit like burnt coolant, but the car does appear to be losing / using any fluids... Any ideas?

Thanks,

Derek

Hi - I have a problem where the CD stacker skips when the road gets only slightly bumpy. The CD player in the console work perfectly on the roughest of roads. Does anyone:

1. Have any suggestions on how to fix this.

2. Know who the manufacturer of the stacker is so that I can get it looked at?

Thanks,

Derek

Hi - I recently bought the above car and it came with two remote entry keys. Both work, but only at very short range - ie within one meter (3 feet) of the car. I have replaced the battery in one of them, but it does not appear to make any difference.

Does anyone have any suggestions?

Thanks,

Derek

I have just bought a '99 C4 - It has 18" wheels fronts are 225/40 rears are 285/30 where sticker under the hood suggests that they should be 265/35. What impact would this have on the rolling diameter / 4WD system? Or are they actually the same rolling diameter?

Hope that someone can help me.

I drive back roads In New Zealand very hard. I drive a 996 C4 2002 The roads here are very rough.

I found I get 7,000km from a pirelli pzero rear tyre and 15,000km from a front tyre. alternatively I use michelin pilot sports. I get 18,000 km from a rear tyre and 25k km from a front.

I find if I run the pilot sports front and rear the PSM cuts in a odd times on the front wheels as the tyres dont have the same grip as that of the pirelli's. This happens at high speeds on uneven roads and can be very unnerving. it only happens with the pilot sports and not the pzeros(on the front)

So what I did and would like feed back on is I am running the PZero's (pirelli) up front and the Pilot sports on the rear(michelin). This means they wear at the same rate. I also get the front end grip I need and can also accerate hard without nearly hearing the rubber wear off the rear tyres (as when I run pirelli on the rear after every drive I measure the tread and for a good run I lose nearly 2 mm)as the michelin at the back are harder.

Now all the manuals I read and car mags when they do tyre reveiws say to always run the same manufactures tyres front and rear. Is this true ???? and if so why ? No one here can give me a good reason that makes tecnical sense to me.

The clear question is can I run different tyres on the front and rear and if not why?
