  1. Hi, I have a 2004 986 2.7 tiptronic, with an odd issue from the rear wheels - any experienced thoughts on it appreciated. When cornering around fast roundabouts there is a noticeable grinding / rubbing noise (which rapidly pulses on and off) from the rear of the car - more noticeable on right had turns around roundabouts, but also happens on fast tight left hand turns. I'm not convinced that it's a bearing, as car done 35k, although I did have a front bearing whining and replaced at 25k miles. Anyone know of anything else - brakes etc that might cause that ?? It's difficult to figure out if its from the RHS or LHS - my hunch is the right. Thanks, Ian
  2. Absolutely fine under hard moderate or light acceleration when driving normally. It only happens when you coast without acceleration down to say 12-15mph, then accelerate quickly with the tiptronic in 3rd gear. The engine then revs without acceleration until it thumps back into drive. I was suspecting the electronics, beacuase it feels like it should drip into 2nd sooner, but instead seem to 'fall' out of gear, then be not sure how to deal with the acceleration. Thanks for looking, Ian
  3. Perhaps this an electronic CPU problem, or something mechanical with the valves ?? Any help appreciated - not sure what to try next ?
  4. Sounds the same as the rear bearing I had replaced on my 04 986. That confused the garage too, but it was indeed the bearing. Not a typical bearing noise - like you say, a mid to high pitch wine at around 15 mph, disappearing at higher and lower speeds. My garage was a little reluctant to change the bearing, but they did, and that sorted it. Ian
  5. Hi - I have a 2004 986 which is running well except for one problem with the tip box - and any help really appreciated. If you coast towards a fast roundabout (for example) with the foot off the gas, the gearbox will stay in 3rd gear as the speed stays around 12mph, but sometimes feels like it drops out of gear, then when you accelerate into the roundabout the revs increase with no drive. The drive will then make a thumping noise / feel 'thump' and pick up drive. I've had a tip service (oil and filter change), but after 400 miles the prob still remains. Apparently no error codes coming up on the computr either. Anyone know what might be causing this, or what the options are?? Thanks a lot, Ian
