Orange engine light just come on. Apparently ma sensor of some sort. Well done Skoda. Great timing just before Christmas when we want to visit family. Also apparently performance now limited and no idea what that means. No doubt will be charged by service station for using diagnostic machine. I have up till now been a fan of Skoda's but not any more. Any suggestions from anyone aside from buying another make

What have you a TSI or TDI?

Thanks for response

It's a TDI. Turns out it was a clogged DPF. Sensor replaces and "regen" fortunately worked. Seems that short journeys are bad for DPF as there is no opportunity to burn off the accumulated particles which can only happen on A roads or motorways at certain revs for a set period. Most people I have spoken to sat they just take their car for a longer run if the light comes on, assuming it's the DPF. Not so good if it's not!

Sorry about that, but fortunately, it doesn’t sound that bad…

Concerning not being a Skoda fan anymore, I fear this problem would have happened to almost any other diesel engine, whatever the brand.

DPF diesel engines don’t like short trips. This contributes to clogging the DPF but also clogging the EGR valve.

Medium / long trips are necessary to avoid that, as well as frank acceleration on first gears (once engine is warmed).

It is vital to use the correct low SAPs oil in engines with a DPF, as the correct oil may result in ash (as well as soot), and the ash will not be removed by driving the car hard. It will be necessary to physically clean or replace the DPF. The correct oil will not prevent ash buld-up, but it should slow it down. It shouldn't be an issue with cars with less than 100,000 miles on the clock.

Also note that many petrol cars are fitted with a similar GPF, and will also need the correct oil. I haven't heard of issues with a GPF,but it doesn't mean that they can't block.

Driving hard (from Time to Time) is not a way of cleaning. But it makes EGR valve move regularly and it prevents the EGR from clogging and finally being blocked and leading to limp mode.

Thanks to all for advice. Will check what oil is being used. I suspect might have cleared the build up of soot with a good blast down a dual carriageway motorway but was worried about doing more damage. Not sure why they needed to change the sensor. Incidentally I think limp mode was already activated as revs seemed to be limited to 2,500.
