VW tyre pressure monitor

Legacy_user

Hi

VW 2015 Touran.

Where can I find a link / info on the tyre pressure monitor fitted within the valve?

The dealer assure me there is one, and I think this could impact on having a tyre replaced in the future.

Dont expect dealers to know anything about the cars they sell.

Standard fit is an ABS system which monitors wheel rotations and simply flags pressure loss, no indication of which tyre.

An optional extra on most VAG cars is a valve system which displays tyre pressures on the dash.

If your car has normal rubber valves it will have the ABS system.

What does the manual say?

Why, the valve will simply swapped onto the new tyre. It'll be fairly obvious that your tyre valve is a direct TPMS sensor or not.

FWIW, my Golf has the ABS type system. There's a warning lamp that notifies about a possible pressure loss, but no individual pressure readings.

The ABS system does work ... when it came on the first time 2 weeks after getting the car I did indeed have a front-offisde puncture. However the system can be prone to false detection if you get wheel slip/lock where the wheels on an axle don't have equal rotation.

OP's probably thinking about the situation where you often get a new valve when you get a tyre replaced - whether you need it or not.

The latest type of TPMS valve with an integral sensor should last for 10 years - so say Continental the biggest manufacturer of them.

They are bolt-in and should not be replaced as a matter of course as with the older rubber stemmed standard type valves.

They have zero impact on repairing or replacing a tyre.

It certainly will have TPMS fitted - it's been a legal requirement on all new models of cars type-approved since 2012, and all new cars registered from late 2014.

The question the op is asking is not whether it has TPMS but what type of TMPS his car has.

That's easy to determine ... if there are no pressure readings (values) then it's the ABS type; if there are then it's probably the valve type.

if it is a new system that displays the individual tyre pressures then it will probably be a radio sender bolted to your wheel and the valve is attached to the radio sender and they are expensive not sure for VW but would expect around £40-£50 a corner and as said above they should last up to 10 years

some manufacturers sell a service kit for them where you can chance the valve core the dust cap and the o ring seals which may be handy if the valve starts leaking

Hi

To cover a lot of the responses... THANKS.

I know it has a warning light, it came on some months ago, and adding pressure to all 4 tyres did not seem to be the solution. The AA man, a nice man ... Very Nice Man, Very Very Nice Man , could not find a fault.

The dealer insist there is a tyre pressure monitor, my lad says it is based on rotational speed, one going faster means it's soft or flat.

Bearing in mind the accepted truthfulness of anything car dealers/makers say I am very skeptical. It is going in for service Thursday and I will be listening very carefully to the answer/explanation.

I find the handbook pretty useless, giving warnings about not driving with the bonnet up or with a wheel missing or other crapulous warnings, and no actual details about anything useful.

The braking system has a recovery element apparently, so when you apply the brakes the amount of stopping force is not linear, nor predictable, so that Aviva drive app would make me a kangaroo client. But what circumstances or conditions the recovery element is implemented is a mystery, and recovering what from where to where.

It's my first VW and it is an absolutely dreadful standard of knobs, controls, switches, software and dials/displays etc. The headlights go thru a computer I guess, because the delay from switch being on to actually illuminating is almost 2 seconds.

The radio reception is better than my previous car, the fuel economy possibly better, the badge is more prestigious I suppose and that is all it's good points listed.
