Probably so. VW Audi have been using indirect tpms for some years now apparently... which is good in that tyres don't have to be removed to replace batteries, my old Passat had the same system & it worked fine (as did the Audi before the new tyres were fitted). I'll keep you informed. Regards, Nick.

No I haven't asked Audi yet but from what I have read the indirect systems have conventional rubber valve stems & direct systems have metal ones, strong enough to hold the internal wheel sensors! Mine are rubberised! Audi want the standard charge of £70 just to investigate plus whatever it costs for any parts & labour on top. Hence I am researching the problem & will most probably sort it myself, if I can't I'll manage without them or take it to an independent! Audi really do take the Micky! Regards, Nick.

Hi Gareth. I have been in touch with the tyre fitters/suppliers & they have told me that this vehicle has indirect tpms which means that each wheel is monitored by the abs system NOT like the direct system which has sensors in the valves! So each wheel diameter is monitored & if there is a drop in pressure it is noted & sends a signal to the vehicles computer which then sends a warning to the dash telling you which tyre/wheel is affected! All very technical. Thanks for your reply. Nick.

Many thanks Steve, I've located it. N

Hi folks. Since having 4 new tyres on my Audi A4 Allroad 18 months ago, the TPMS does not seem to function, when I switch on the ignition the low tyre pressure light works but it does not show when there is an actual pressure loss in any of the tyres. I have reset the dash computer to the correct tyre pressures but doesn't make any difference. Also, does anyone know where the diagnostics socket is on this model? Thanks, Nick.

Thanks Gareth for your thoughts. I pretty much have only used the car for long runs eg. holidays. We tend to walk a lot locally rather than use the car whenever possible. I'm retired so don't need to use it for work runs! I have read on the Audi website that genuine Audi waterpumps are good for 100,00 miles whereas aftermarket ones only 30,000 so don't think I will change it! Cambelt & tensioner I think I will probably have done, for my own peace of mind, (reluctantly).Thanks again. Regards, Nick.

Hi, I'm new to the forum. I'd like to know what thoughts are. My A4 Allroad 2.0 tdi 2018 has only done 26000 miles in 5 years so is now required to have a timing belt change. Audi have quoted £600+ for this, when I asked if that included water pump and tensioner they said that would be another £300+. Is it really necessary to have a new pump at this mileage?
