Hi - a quick summary of my recent adventures. With a very special thanks to briskoda forum members Urrell, langers2k, Sad555, ernieb and kenfowler3966. My 9-year old Skoda Yeti 2.0 TDI had a slightly rough idle, slightly underwhelming performance and - most importantly - a warning light for glow plugs (flashing). The code was EGR Valve - Open Circuit (P040300). I had an independent garage check it out, and I bought my own scanner to confirm. As the car had the fix just under two years ago, following advice from this forum, I contacted Skoda UK customer services. Skoda UK immediately agreed to a free diagnostic and to replace the EGR valve free of charge. This took two days and is now just back from the Skoda garage. The rough idle has gone, performance is normal again and no light. I asked the garage whether the EGR had failed electronically or because of sticking (caused by 'coke'). They confirmed it was the latter, it was 'coked up'. I do a lot of short city runs, and will be trying to get the car out for longer motorway runs to try to reduce the potential for this happening again. I'm also going to use my scanner to monitor the PDF filter, which also has a sensor. Again, my thanks to the forum and in particular Urrell and kenfowler3966. You saved me near enough a thousand pounds! Best wishes, Duddy.

Thanks Ken. We'll start doing some longer trips once the youngest (currently 4mo) is a little more robust. Up the road a few hours to see the grandparents every now and then. That's good about transient faults, I hadn't realised that. Thanks. I'll certainly try and get as much as possible sorted within the extended guarantee period. Remapping - this wouldn't create any unexpected problems at MOTs etc would it? Thanks again.

One thing I was wondering though, if the light for some reason doesn't come on that morning what would you do? Phone and rearrange the appt? The light seems intermittent. Although I know it's the EGR because I've know got a reader and I get the same fault code as the independent garage got.

Update. Skoda UK has given me a case number and case worker. They requested the car gets taken to a specialist Skoda garage. Spoke to her earlier and she has agreed to waive the costs of diagnostics. If it relates to EGR valve they will meet the cost of replacement as a gesture of goodwill. The local specialist garage could only look at it in two weeks time, but the one across town will look at it in a weeks time. The latter, though, tried to tell me if the diagnostic didn't suggest anything linked to the emissions fix they'd charge me 99 quid to run the test! I said Skoda UK had agreed to pay regardless of the outcome of the diagnostic. So, fingers crossed. Duddy

If it goes within the next 6-months I'd be able to pop along with my competition certificate, beyond that it's out of the 'two-year agreement' period. Do you guys use a particular code reader for the Skoda Yeti that you'd recommend? I might need to manually clear in the future... Will

Thanks - I'll give it a shot. Do you think it's highly likely the warning light will reappear, or can the valve really just have a fluke one-off problem? And if Skoda Service Centre doesn't play ball: is fitting blanking plates and remapping a better solution than £1,000 to replace it?

It had the 23R6 fix in January 2017, before I bought it. The paperwork just says W-Engine Control Unit, among other stuff, and a Certificate of Completion from Skoda which says 'NOx engine control unit'. The garage I've used since buying the car six months ago is a local independent, small and well regarded. When I popped in to collect the car the guy said he gets lots of these problems and it's often a sticky valve. He might have been simplifying it a bit! Advised I take it out for a good motorway run once a week and to come back if the problem happens again. Thoughts?

Hi - I bought a 9 year old diesel Skoda Yeti 2.0 TDI 6-months ago as a first-time family car. It has less than 50k on the clock. I do lots of short city journeys. I bought the diesel because of the all the negative press, which meant it was cheaper in the second hand market. I'd have otherwise gone for a petrol. Anyway, the other day: the DPF light comes on. I follow the manual and blast down the road for 20 minutes at 70 mph. Back home, turn off and on - light has gone. Next day, turn on - drive 15 minutes, the glowplug light comes on (not flashing) and the engine management system kicks in. Limping back to the house, notice the control system for the exhaust light is now also on. Let it sit in the driveway for a couple of hours, try again and this time the glowplug light is flashing, along with limp mode and the exhaust warning light on too. Next step, on the way to the garage, the glowplug has cleared but the exhaust remains. No limp mode. The garage ran it through diagnostics and say it returned a "EGR Valve - Open Circuit" error. They were very honest, it'd cost a lot to deal with in terms of labour (as I'm sure you all know, it's behind lots of other stuff). So they've cleared the warning and driven it around with no problems. He says take it home and see what happens. He'd not want to look at the EGR Valve until we're certain there's something wrong with it. My question: Do you think there's a link between the DPF light going the day before, and then this problem with the EGR Valve the next day? I do lots of short-journeys, so I'm trying to work out what I might do differently with the car (e.g. not interrupt the regen cycles!) which might prolong the life of the EGR Valve. Thanks.
