| Post subject: | Warning Lights |
Afternoon, I've had two warning lights come on today: one for low coolant level and one for brake pads. 1/ the coolant level is only slightly below the line. Is there a specific type of coolant that needs to be used on 928s? 2/ I've checked the front pads (as the rears are nearly new) and they seem to have about 16mm left on them. Is there a fault with a sensor or has Porsche set them to give very conservative warnings? One other thing. I need to buy a tyre compressor for the spare wheel in case i ever get a flat. Do any of you have the genunine Porsche item and if so, does it fit inside the spare wheel. I'm not sure if a compressor and the jack will fit in. Maybe a large can of tyre sealant is a better idea. Thanks in advance. RB |

The compressors come up a lot on Ebay .. older ones for £50ish, but I picked up a new one off a 2008 Boxster for £25. (not the same but at least living the Brand!) |

I have the Porsche item and it does sit in the wheel ok, but the jack lives under rubber strap at rear of hatch. Mine doesn't come in car though. I keep it for completeness but it's a fairly poor compressor or maybe it's because it's almost 20 years old. Takes ages to inflate to pressure using it to top up tyres so heaven knows how long it would take to inflate space saver. I bought a Michelin compressor at Halfords - they still sell them 1/3 off - and it's very good. Nice screw connector to valve and it turns off once set pressure is reached on digital read-out (seems to read about 2psi high). Sounds more convincing in operation than Porsche job and is relatively rapid. I also carry a can of the Porsche inflator gunk so belt and braces really. I wouldn't want tl have to use space-saver as I think it only fits on front axle so possible extra work there, you have to carry the old tyre in hatch and it's very hard to deflate the space-saver without ratchet straps! |

I also bought the Michelin compressor from Halfords and very impressed! Had a slow puncture for ages on my Jeep and it made short work of pumping it back up. Good product. Also has a set of led lights in it so you can see at night. |

Yup that's the one I have Watchcam. Has now earned its place in my 928. Have to keep on top of my pressures as I have RDK system and have kept it enabled. It's very accurate but will throw up a warning if you are more than a few psi below the recommended pressures so prior to getting Michelin I seemed to be using foot operated pump every couple of weeks to turn off warning consistently coming up on two tyres. One of slow leaks was around the RDK sensor which I've had sealed and is now OK - I haven't had the other tyre checked to see if it's seal at rim or again v. slow leak around RDK sensor but I suspect the latter more probable. I like the RDK sensors though as they consistently cause amazement at tyre places as no-one has ever seen the like and they can't believe tyre can be balanced with them in place. I think modern pressure sensors are built into the valve where cars are equipped with the system. Good old 928 ahead of its time (I think they borrowed the RDK from 959 but it was a first for Porsche road car). |

I believe most cars use the ABS sensors to detect different rotational speed from the other 3 & then flags a flat. |

That's interesting Jim and makes sense as low pressure tyre will have smaller diameter. Either way you should have seen the faces on the fitters in 3 places in my town recently when I had to have a puncture repaired in hurry (had to go to three because they either didn't have working machine big enough to take wheel or took fright at the sensor!). They were all calling their mates over to look at the Porsche sensors as if the tyre had come from outer space or something. I think someone like BMTR in Birmingham would have been a little more sanguine about Porsche RDK wheels of that vintage... Secretly I rather liked having something unusual but that's 928-syndrome for you. |

If the coolant in your 928 is blue or green, then you can use the Halfords stuff. Go to the local Halfords and tell them your coolant is blue (or green) and they will point you in the right direction. At least they did for me here in Bracknell. Cheers Chris |

I have the pink Halford Advanced in at the moment which I changed a month ago. Honestly if it's just below the seam top up with distilled water. If there's a leak then this requires more timely attention than choosing coolant. In any case I don't think there's ever been an agreed standard for coolant colour, and furthermore most heads are aluminium so I suspect most decent coolants are fine. If I can find it I like Prestone though. Your opc will aslo sell you the guaranteed Porsche stuff so no possible concern. |

The eBay one. Very good price - even with p&p £5 less than I paid in Halfrauds. |
