S2 Niggles... any suggestions?

[944 man]

The wheel is a hands-on diagnosis: Im sure you realise that it shouldnt be touching. Id suspect warped discs and Id suspect that theyre Zimmerman discs. If the discs are true then itll be difficult to get to the bottom of: it is a known issue though, caused, I think, by the hubs. The ABS is extremely primitive: I presume that the tell-tale light operates correctly? Id suspect that the connections onthe back of the instrument binnacle are to blame here, although it could be a poor earth: earhts on series one and series two cares are dire. Simon

Interesting, as I've had a good 100 mile run today to try the new S2 out. Brakes are all as new, bar an advisory that the calipers will need refurbing in about 3 years time. Discs and pads are all replaced recently, not Zimmermans [&:]. There is a very low-level judder there; not enough to make me want to do anything about it as I know there is a tendency for S2s to suffer from this. I'd not consider it a problem, just a mild irritation as I know it's there. Any serious judder I'd want to delve further.

I had an annoying noise from the steering wheel/cowling of my s2 when i first had it and on removing thr wheel found the wiper pad contact for the horn to be bent,a little re-bending and all was well,hope this helps, all the best John.

Thanks for the useful advice guys.

Absolutely loving my new toy (944 S2), it is without the most rewarding car to drive I've ever owned. My car is a very honest '89 S2 with 122K on the clock.

Having spent the last few days driving the wheels off it, I've enviably found a couple of niggles I'd appreciate any suggestions on.

[] The steering wheel makes a rubbing sound when you turn the wheel. I can feel it rubbing on the cowling and it's very annoying.

[:'(] The brakes work very well but have a horrible judder. Strangely it doesn't seem so bad if I'm turning at the same time?

[]Despite the car supposedly having ABS, I seem to be able to lock the brakes under very heavy braking?

[:'(]The rev counter needle flickers erratically before settling to give a reading.

All comments welcomed.

Cheers in advance.

My car likes a slurp of oil! I've managed to burn a litre in one tank of fuel. I have to admit the miles I've done have all been for pleasure, so once warmed up,I've been giving it plenty. Is heavy oil use normal?

 

[944 man]

One litre per one thousand kilometres / six hundred and twenty miles is within tolerance, according to Porsche. Thicker oil helps.

 

[evoboy69]

It's used a litre in less than half that! Is it a litre between the marks on the dipstick?

 

[944 man]

It is one litre yes. If the car isnt losing oil then Id try running it on Castrol GTX High Mileage and seeing how it fares. The following is what Porsche said in their North American user manual. In the European manuals they do set a limit, as I mentioned earlier. "Engine oil consumption It is normal for your engine to consume oil. The rate of oil consumption depends on the quality and viscosity of oil, the speed at which the engine is operated, the climate, road conditions as well as the amount of dilution and oxidation of the lubricant. Because of these variables, no standard rate of oil consumption can be established, but drivers should expect an increased oil consumption at high speeds and when the engine is new." Simon

The Porsche tolerance figure is stupidly high IMHO, but every car is different and depends on the use it gets. My S2 at 190k miles does not need any topping up between 6000 mile oil changes.

Thanks for that. The first thing I did was put a litre of oil in it when I picked it up last week. I’m still awaiting the service history so I don’t know what oil is currently in the sump. I topped up with 10-40w semi synthetic. Underload I can see exhaust haze but not blue burnt oil. I searched the forum earlier for the best oil grade to use but got confused by all the differing opinions. If it’s going to use a litre of oil to every tank of fuel, I won’t be using fully synthetic!

 

[Diver944]

10w40 is in the middle of the ranges recommend by Porsche in the manual but if your car is a bit older and using oil then you can also use 15w50 which is a bit thicker when both cool and hot.

 

[944 man]

It is high, I agree. My old 130,000 mile series one hardly used any oil when it was caned across Europe. On both Autobahn days it had only used a few MLs and I couldnt see any difference on the dipstick after a day at Brunters.

 

[evoboy69]

What oil do you use?

 

[944 man]

Oil type is always a contentious subject. Id suggest that 10w-40 isnt suitable. I was given several containers of excellent 10w-40 synthetic by an oil supplier and Im still using it in my car and it definitely costing me one atmosphere of pressure when it warms up. Itd be ideal for my Impreza; but 20w-40 or 20w-50 is far better suited to the engine: Im not sure that Id be using a synthetic in most cars either. Simon

I would say that my S2 uses no oil either (or very little - less than a litre between oil changes every 5000 miles.) However I have just driven it to the in-laws (London to Shropshire) and back this weekend, and it has used a chunk more than I would have expected. I probably put 150ml in it this morning, and that didn't take it back up to 'full'. That's around 380 miles of driving. I suspect that driving style is relevant. I did give it more beans than usual, which may explain the greater oil use. I'll monitor it over the coming few thousand miles and see what develops. Oli. ETA: That's 10w40 semi, at just under 150k miles.
