hi all.

How good is the tire pressure indicator? My came on today after only 750 km of driving and wondering if it is correct.

Any comments?

It's possible you picked up a nail after 1km never mind 750, check each tyre, if thay are all spot on it may be a fault with the tpm which would be sorted under warranty.

It's an indirect monitoring system that uses the ABS/ESP sensors on each wheel to measure rotation speeds (an under-inflated wheel rotates at a higher speed due to it's smaller diameter). But it also has software to manage out false readings (bumps in the road, irratic driving, sudden changes in temperature, etc.), but it's not immune to false alarms. On a slow puncture it can take a long time to pick up the difference, where as a sudden loss of pressure will be near instant.

As Black vRS Oct suggests, check for obvious damage, check the pressures. It could just need a reset (hold down the button until you hear a bong), could be a faulty ABS sensor in one wheel.

I certainly wonder how sensitive the monitor is. On Sunday, after driving a few hundred metres, the light came on and found left rear partially deflated. When I took the tyre to be repaired it was irreparable and the tyre guy said it had been driven on for some time while punctured though we hadn't noticed any problem. He showed me the tyre and it was obvious the canvas was damaged, so I don't think he was just trying to sell me a new tyre!

Don't know how sensitive, but based on your example I would say that it was effective!

How much longer might you have driven for on a partially deflated tyre if the TPM had not alerted you to the problem?!

Worked for me last month - came on and rear tyre was down by 15psi. The rears were pumped up to max as I'd been carrying 3 kids and luggage.

I reckon the light came on when the pressure was almost 30% down.

Due to a couple of factors I just stuck a compressor on it and brought it up to pressure - the warning light came on again the following day and I again added air and had time to get the wheel off. I had a nail in the centre of the tyre which was repaired for 15 quid.

without the warning I'd have ruined the tyre.

I have found the system to be quite effective on the two Superbs that I have owned.

Detected a 5psi drop in one wheel with a very slow puncture which allowed the tyre to be repairable.

I still check pressures quite frequently though and re-set the TPM afterwards.

I agree. It did alert us to a problem otherwise unsuspected so did the job

Thanks for the tips.

I checked the air pressure and the front tire to the left was a bit low.

Pumped it up and did the re-set and the warning light disappeared and did not come on again today.

Will be worth taking the wheel off to see if a nail is stuck in it somewhere- should not loose that much air.

I have found the system to be effective.

collected 4 large people to take to airport with **** loads of luggage just after getting new car....warning came on....stopped to check pressures...all found to be ok.....put a bit more air in rear tyres because of load.....reset ....continued journey with no problem.

2 days later still no new warning.

I've had 3 warnings in the last 3 weeks. I check the pressures and they always seem ok, so I just reset and drive off again.

Sounds like I have a problem with a sensor somewhere then.

There is no sensor.

There is no sensor.

The ABS/EPS sensor on each wheel.

Read what I mean, not what I write. There is no SEPERATE sensor for tyre pressure...

Yep, got that thanks, post #3.

So in the last 3 weeks, I've had 3 TPM warnings and each time I have checked the tyres they are at the same pressure I started with. Not even lost 1 psi.

Must be the ABS sensor then.

Never had a problem with my Skoda, but on my old Leon it had the same system. The three times the warning light did come on I pulled the car to the side and found large nails in the tyres causing a rapid deflation. Once it was even on a motorway. It was a simple must have for me on my next car and was actually one of the reasons why I picked a Skoda over another mark this time round.

TPM saved me third time in a year today. Unfortunately tyre needed replacing as puncture was too close to the sidewall.

It is moments like that, that you need to remember how useful TPM actually is when buying a new car.

Mine's now booked in for first service + TPM problem + a few other niggles.

Most useful and accurate. It detected a slow puncture and after hitting a pothole indicated that I had blown a tyre wall. I've become a bit anal now about tyre pressures and the indicator I find to be most accurate. If it comes on I don't ignore it.

My TPM came on during the week. Checked all tyres with my Michelin pressure gauge. Left rear was down 3 psi so pumped it up. Next day the warning came on again. Same tyre down 3 psi. Left it alone and checked the next day, it was down another 3 psi. A quick once over with my hand and I felt a nail head in one of the deep grooves. Off with the tyre and on with the skinny spare. While cleaning the wheel to put into the wheel well I noticed a couple of interesting things. The wheel was made in 2007 (the car is a 2011). The balance weights are zinc. The Skoda centre emblem is made in Germany. The 18" Themisto fits into the tyre well (snug) but the "tool tray" will not fit inside the wheel. I am now thinking about buying a full size spare and trimming the tool tray. Also noted what I consider to be a lot of tyre wear for only 10,000 Km. It is fairly evenly worn with perhaps a bit more wear on the inner 1 1/2" of tread than the rest. I normally run 38 psi in the rear. It is a V6 wagon.

any body no the correct tyre pressures for a superb elegance estate 140bhp with orig conti tyres?i no that its wrote in the fuel cap,but i only understand pounds :
