Replying to: Mr_Shiftright (May 30, 2009 1:53 pm) I plan to blow air through the high side line toward the dryer (disconnected of course) into a cloth rag and inspect it for particles. What about the oil capacity? Any idea whether the 1.5 oz. pre-charge will be adequate? I can't find the specs online and I haven't purchased a manual yet (although I will probably do so real soon). Found a used Bentley brand at Amazon.com for $107. Thanks.

Replying to: mhutchinson (May 30, 2009 2:11 pm) * The oil should be replaced whenever a ruptured component is replaced, because the quick discharge causes some of the oil to be released along with the refrigerant * Use only PAG oil in an R-134a system (not mineral oil) * Use only mineral oil in an R-12 system (not PAG oil). * Add the right amount of oil into the system when replacing a major component such as the compressor; condenser, or evaporator. * When replacing the compressor; drain the oil from the old compressor and measure the amount. Turning the clutch plate by hand helps "pump" out any remaining oil. Inject an equal amount of fresh oil. Note: service compressors are shipped full of oil; this oil must be drained before the new compressor is installed. * When replacing the condenser or evaporator, add 2 oz. of oil to the system. * When replacing a receiver/dryer, add 1 oz. of oil to the system. * You do not need to add any oil when replacing a hose, since hoses do not collect much oil. * Oil can be added to a charged system using the Robinair 18065 oil injector and a manifold gauge set, or the injector bottle on the ACR4 unit. Now those figures are not "total fill capacity", which I guess is for a total overhaul of everything. Those specs are: Nippondenso 160 ML +/- 15 ML Seiko 180 ML +/- 20 ML So I guess what this is saying is that you still need to know the capacity of the compressor and then add extra if you replace the dryer or the evaporator, right? The total fill specs seem to indicate something like 5 or 6 oz. I think an ounce is about 30 ML Funny German names in there, huh?  PS: Watch out---from 9/98 build date, you have different refrigerant capacities than prior to 9/98. Minimum Charging Pressure is 10 BAR |

Replying to: dfrilot (Mar 17, 2009 9:32 pm) full synthetic does not have naturally occurring aromatic hydrocarbons and other compounds which cause sludge like dyno oil, so I would stick with that, although topping off with dyno between changes is fine. Amsoil is not snake oil, its a great oil if a) you can afford it, b) you change your filter every 5k but not the oil, and c) test the oil for breakdown around 10k to decide whether to change it. I'd rather buy Q from wally world and change both every 5k. |

I had the CEL switch on in The Blue Max, my '00 528iA. They checked the codes and it came back as a fault in the Evaporative Emissions System. They checked it out at the indie shop I go to and found that rodents had eaten away at the hoses connecting the gas tank to the charcoal canister, cost to repair (mostly labor  $90/hr)=$190. I don't know whether to laugh or cry. I had to replace rodent damage to a previous car when they chewed on the A/C wiring ($700!) in the fender and have taken several anti-rodent measures including D-Con packs and moth (camphor) cakes under the hood. I don't mind those chipmunks running a Club Med for rodents on my property but this *&# has got to stop.  Any ideas.

Replying to: andys120 (Jun 05, 2009 7:14 am) As for discouraging the little buggers, I think trapping them or that sticky paper stuff might decrease the surplus population. But an all out cure? Probably not possible unless you rodent-proof your garage, which isn't easy unless it's all concrete.

Replying to: galama (Jun 09, 2009 7:18 am) I've had similar problems w my E39 and other cars. They occurred because the motion detectors are VERY sensitive and can be triggered by falling leaves or even a gut of wind especially if the sunroof is left open. If you don't believe me try dropping a pencil thru the open sunroof after locking the doors. The cure is simple, the motion detector can be disabled by a second push of the lock button (after the first push to lock the doors) on the remote. |

after switching off my '00 528iA. I called my Indie Bimmer techs, without seeing it they guess it's probably the tumblers in the lock which can be replaced. Anybody ever have this problem on any car? |
