Warning lights

[Hugh Mally]

We’re on our way back from 4 weeks in France, Germany and the Netherlands, and overall the T6 has performed well. However, there has been a flurry of warning lightage (ABS, tyre pressure indicator, anti skid, ACC etc) which seems to come and go at will. In addition, (and it could be me being paranoid) but I sense a slight loss of power noticeable on inclines and occasional hesitancy when accelerating. I’m a fairly steady driver - rarely exceed 70mph and don’t go in for hard acceleration or braking unless required.
My suspicion is a faulty tyre pressure sensor (not uncommon apparently) but this wouldn’t explain a slight loss of performance……. or could the system be partly responsible?
It will be going in to VW as it’s still under warranty but if anyone has any thoughts or pearls of wisdom, it would be good to hear you! Cheers

ABS sensor. I'd put money on it.

Almost certainly a wheel speed sensor failure, the performance issue you mention will probably be your caution. There certainly isn’t a link.
If you have a code reader it will indicate which sensor is at fault, cheap to purchase, put your reg’ into Autodoc or similar and check compatability.
Both nearside are the same, both offside are the same.
Quick to renew, a do at home job if you have the tools.
It’s worth getting a code reader, see Carista on Amazon, you’ll also need the app. Other brands available but Carista is a good simple tool, some free functions, some need subscription.

I don't know about VW, but on my Volvo when a sensor went it did feel sometimes like performance was being held back just slightly on occasion. Turns out the same sensor has its signal used for the traction control, and as the sensor was misbehaving the car would sometimes think the wheel was spinning and rein in the power for just a fraction of a second.

No, I didn’t think there would be a link but just wanted to put it out there just in case - I’ll get my right foot tuned up!!!
I’m going to get the dealership to sort the sensor out seeing as how I paid top dollar for the van - get my money’s worth

They don’t seem to last long, try and make sure the dealer fits OEM, Bosch, Pagid or similar. There’s a big variation in the unit costs and that almost certainly corresponds with quality.
