Emissions Fault Warning

[Kingham]

I’m getting an ‘emissions control system’ warning light and a scrolling message to ‘check engine’, but I’m only picking it up occasionally and always when working the van harder.

I was commuting home in October and doing 70mph the first time it illuminated. I stopped in a lay-by and switched the engine off, which immediately turned the warning off. Keeping the van at 56-60mph, stopped the light coming back on and I put it to the back of my mind after a couple of months. It did it again just after Christmas, again whilst going faster and immediately reset on switching the engine off and back on.

Due to it immediately resetting, I thought there was no underlying issue and never got round to visiting Peugeot with it. There is no drop in performance at anytime, either while the light is on, or after resetting it.

Climbing up to Rest & Be Thankful on our way home yesterday, the speed was down, but the revs up in lower gears and it illuminated again. As before, it immediately reset and I’m now looking to take the van to Peugeot to get it sorted.

Before Peugeot take my eyes out with diagnostics, is this likely to be the EGR valve, EGR sensor or possibly something unrelated ?

My previous car used to do that until I stopped filling it with cheap supermarket fuel.

My car does that when it's rained overnight. Well known with Skodas apparently.

Ken, buy yourself an icarsoft reader which will be specific to your vehicle.
Its the next best thing to a professional reader & can interrogate your Kingham's memory & point you to
exactly whats going on, generic readers just generalise & can be helpful, but just don't have the finesse.

Try looking on Ebay at number 303351008986.
I haven't read the advert yet but, we have the Mercedes version for our R Class & it paid for itself first time out of the box.

It’s always run fine on a mixture of supermarket and main petrol station fuels, but could be worth experimenting with.

Now you tell me ? I recently bought an Octavia Scout.

Cheers Robert, I’ll have a look. My problem is knowing what to do with such info ?

Sounds complicated but tis easy Ken.
This icarscoft gadget allows you to clear or reset the memory & tells you exactly what is going wrong.
Then you can sound clever when you phone the garage to ask how much for a repair.

Get back to me if you need more help mate.

Kind regards...Robert.

I had this with last motorhome. Initial advice was to drive at least 10 miles 3rd/4th gear at high revs. This didn't work. The AA tried to do a regeneration but again no joy. Eventually went back to dealer who sent it to Fiat and diagnosis was a faulty sensor.
