    IIRC the Lexus one is something ridiculous like £40, I got one off Ebay for something like £3. It's not perfect as its a little narrow at the top but I put some foam on it to stop it moving, but hey it was £3 Vince

    New Range Rover Evoque. Would you?

    No, my brother got rid of his after it started costing him big time, think the worst was the steering rack, cost £1200. He now drives a Hyundai and he says its actually a much better car. I know someone else who had a Freelander and it randomly started lowering one of the rear windows about 5cm - he had to be very careful when leaving the car as it sometimes did it when the doors were locking.

    Tell them that if their forums are quiet, its because many ex Saab drivers are now driving Lexus and so they can be found over here Vince
  4. Had something like this on my Honda CRV, got progressively worse, was looked at several times, in the end it had to be sorted as it became a violent shaking, front drive shafts was the cause, the rear was discounted by temporarily removing the prop shaft. Vince
  5. Yeah, this all harks back to the 80s, plenty of cars were getting stolen , you didn't even need to smash a window, I think Ford Escorts were a big target, but I do remember Vauxhall Astra's were as a mate of mine had 2 Astra GTEs, the 2nd replace the 1st after it was stolen, after the 2nd one was stolen he switched to something else. We actually broke into his car whilst he was sat in it, you only needed a piece of that plastic parcel banding with a notch cut into it. You fed it down the side of the window from the outside, fished about and you could pull up the lock mechanism the same as if you were in the car and pulled up the lock at the top of the door as most of them were back then, nowadays its usually on the same position as the internal door handle. We tried this when it was reported that Astras were easy to get into, turns out they were. This is why may people had Crooklocks on their steering wheels etc. Nowadays, most cars have deadlocks, the 1st lock actually locks the door, the 2nd disconnects the mechanism form the actual lock which is shrouded in metal to prevent tampering. Many cars also have immobilisers so you can't 'hot-wire' them by simply shorting the starter motor wires. Vince

    Yeah, I saw that one, knew about the issue already, applying the fix is reasonable, its expensive if its already gone as that needs welding and its not an easy place to get into which is what pushes these into becoming write-offs, cos these cars are getting pretty cheap to buy like the one rich1068 got,.though it certainly doesn't look cheap.

  7. My experiences are along the same line as darrude, only occasionally have I felt anything other than a smooth ride. In a conventional car, the CC would vary the engine speed to maintain road speed, in a hybrid the system would probably leave the ICE at a constant speed whilst varying the electric side of things to "trim" the speed, in my experience this is done quite well. You can set the car so the rev counter is on in All modes, I did this for a while, interesting to watch the ICE switch off as you waft along the road. Vince

    Did over 1000 miles with the Engine Light on in my 9-5 Aero, occasionally message appeared on the info screen too, so I knew it was down to the battery, still expect some codes to show up is this is the case. I say this as you have had the light go out as well, which happened on mine too. There were several versions of the oil breather setup too, check those are okay and clear. I remember that if the oil level was getting towards the low end of ok, I could get the oil light to flash on going round the Raleigh Island in Nottingham, but you had to be driving briskly, the Aero used a little oil, needing a topup of about 1 pint between 12k services which for me was about every 18 - 20 weeks. Hope you get the little niggles sorted as that is a beauty of a car. Vince

    Regarding the heaters, if it doesn't blow warm air, but it does cool, then the suggestion of flushing the cooling system may work, on my 9-5 Aero, I had a situation where the heating was working, but in stop start traffic if stopped, all sorted itself out after I had the thermostat done when it failed. Tidy car, nice colour, it was this colour which brought me back to Saab when I got my 2nd one. Enjoy. Vince

    As someone who has owned 3 Saabs, I looked into buying a 9-3 convertible a few years ago, the only thing I remember is that models of certain years were prone to having the bulkhead cracking around the steering column, which on an old car could be a write off unless you're prepared to pay to sort it. I believe the last version produced has it all sorted and there is a colar that can be bought and fitted to prevent the issue from happening on the other versions but since it has to be fitted to the bulkhead, its not the cheapest of fixes either. As far as I know, this only affects the convertible model. Vince

    Mesa Red

    Yeah I got a Mesa Red IS, I actually went to look at one on a dull day and decided against the colour. Then after more looking, I decided, no, I like the colour, and in the sunshine when its clean, it simply gleams due to the gold flecks in it. On a dull day, it can almost look burgundy, and yes it does show up the dirt, thought red wouldn't. Vince

    Hybrid Battery Meter

    Correct, though after I posted I realised that I made a small mistake, the MG2 doesn't spin slower, its speed is directly linked to the road wheels, its just that the rest of the system, its just that the MG1 takes the energy and spins the ICE as I said. Vince

    Hybrid Battery Meter

    In a normal car system, the alternator can be disconnected and then it just spins and provides little resistance, this is correct. However, in a hybrid system, the energy levels are much higher and crucially the system is connected to the road wheels, as it says in the first part you quoted "(MG2) is operating as a generator, it creates resistance to rotation at the wheels", this is normal regen occuring. In the second part this is describing braking at higher speeds, if they switch the ICE off, the MG1 would need to spin extremely fast backwards, has a good demo of this on the Prius, the maximum speed with the ICE off would be about 42mph so when they say "protect the planetary gear unit", they really mean MG1 as they don't want it spinning too fast, this is still normal regen occurring. So from higher speeds, at some point when you are going slow enough, the ICE goes off, if you set the tacho to always on you can see this all the time. In downhill braking, even at say 20 - 30 mph when the battery becomes full, this is not the same situation as described in part 2 as at those speeds the ICE would more than likely be already off. But at some point the ICE comes back on, I've witnessed this a few times, descending the Cairn O Mount its easy to watch it all happen as you don't want to come down there at any great speed. So descending at around 30mph in silence apart from the brake pads on the discs, the ICE suddenly come on a short while after the battery appears to be full, and the ICE runs at something like 2000rpm. So whats occurring here is a little different, the main braking is being done mechanically, but since the MG2 is connected to the road wheels at a fixed ratio so it will keep generating power, but if you could disconnect the circuit, this would be done using electronics so would have large energy across the electronics, not good. Also you would remove the load as the load is created by pushing the electricity into the battery and you don't want a sudden decrease in braking. So by spinning the MG1 you cause the ICE to spin and this allows the MG2 to spin slower, the energy of this slower spin is used to keep the MG1 spinning which is spinning the ICE, so the ICE is providing the load via MG1 to MG2 and hence the road wheels. The whole system is beautiful in its simplicity, it however requires some very sophisticated software to keep it all in check. Vince

    A petrol engine will create mainly CO2 and a little CO, usually the CO is created when the engine is not running at its most efficient, now since hybrid systems are all about efficiency, they are designed to run the engines in as an efficient manner as possible - hence the atkinson cycle, in fact the atkinson cycle is supposed to create lower emissions of both NOx and CO.

    The servo assistance must be electrical as most of the time when slowing down, the engine is usually not running when you get to the mechanical stage of braking, ie from about 5mph if you do it just right. Other items like the AC are also electrical rather than driven by the ICE. The way the engine / electric motors all connect through the gears, the electric motors can not be disconnected so they will be spinning and electricity will be generated, this has to go somewhere so the engine will spin as a load - it doesn't need to use any fuel, it just needs to be spun by the system to create a load to dissipate the excess energy, the continuing for a few more seconds would just use up a little more energy. The control of the engine is achieved by using a second electric motor which can spin forwards or backwards to mate the speed of the ICE, the electric motor and the road wheels, its all very clever and actually extremely simple which probably helps with reliability. There are several videos on YouTube explaining how it works, the Weber Auto one actually show the inner workings of an actual gearbox / motor setup from several versions of Prius, which are fundamentally the same system, in one of those videos he mentions the engine spinning as a load for the system when there is excess electricity. Had this very effect recently on a trip up Scotland on a road know as the Cairn O Mount, battery fairly depleted at the summit, filled up pretty quickly on descent and then the engine came on about 2/3rds of the way down.
