2014 140ps Yeti Intermittently Loses Power

[twigd]

Hi all,

Both myself and Skoda appear to be stumped on this so I'm hoping someone might have an idea.

A few months ago, about 8000 miles in, my Yeti would very rarely stall when going away from traffic lights. So infrequently in fact, I thought i had done something wrong.

Gradually over the past few months the issue has grown in to it stalling frequently at lights and also loses power when travelling at a consistent speed. There's no error lights, no error messages on the computer and the car just won't go above 1500rpm and no power is delivered to the wheels. Usually restarting the car after a stall or just changing down a gear would seemingly fix it for the rest of the journey, however now it can take up to 7 restarts of the ignition or changing down several gears to get any drive what so ever.

Typically the garage is struggling to know what to fix as there's no errors and they say they haven't been able to replicate the issue. Anyone know what I can do next, as its genuinely not safe to drive. Any thoughts on what it might be would be much appreciated.

Thanks,

Tom

Unclean fuel?

What is the 140 Yeti, petrol or diesel?

Is the garage taking a live feed from the car, or just checking for codes after you have tried to restart it?

[AJ7788]

My immediate thought is EGR valve - had the same issue on my previous Octavia where it would lose power intermittently. Mostly on the motorway for me when doing a constant speed as well.

Tell us more about your car.

Manual transmission?

Was it bought new? Warranty left?

How many dealers have dealt with/serviced the vehicle?

If it's under warranty.......get a temporary replacement and have them experience and deal with the dangerous nature.

[twigd]

It's manual, diesel, purchased brand new in March so plenty of warranty left. Two dealers have had it now for a total of a months and neither have been able to replicate.

Where are you?

Where are you?

I'm in Nottingham.

Have you tried Rainworth's

Have you tried Rainworth's

It went to them first I'm afraid.

Get the dealer to escalate it so that Skoda Technical get involved.

Can I ask for that? Or is it best to contact Skoda UK directly?

[Llanigraham]

Best to do both!

Sticking EGR valve would be my guess.

I had a similar issue with a Peugeot 307 diesel.

It would cut power going round left hand bends every now and then and, like your Yeti, lose power at steady throttle.

It turned out to be the throttle position sensor.

Assuming the Yeti has fly by wire throttle, it may be the same cause ??

[gumdrop]

My Focus did that twice after a lot of head scratching the main dealer involved Ford Technical,

turned out to be the fuel cap, which was replaced and I had no further trouble.

So many things can cause similar symptoms. I'm a bit surprised there are no fault codes though.

 

Before all the electronic gadgetry I had a Suzuki van that did something similar and I doubt if the sensors fitted nowadays would have picked it up.

The garage replaced the carburettor (remember those? ), fuel pump and filler cap, cleaned through the entire fuel system, all to no effect. Leave the car for a few minutes and it would be OK.

It eventually turned out to be a large diameter rubber hose between the carb and the air cleaner. It only showed following a trailing throttle on the overrun when the induction pressure dropped "sucking" the hose closed. A new £4 hose cleared the problem but I never got the other costs back!

I suspect that there are codes, but only "live" ones, and every time the car gets turned off they clear, which is why I suggest they do a "live" test.

[Frenchtone]

^ but that would mean a long term live test, they wouldn't want to do that if its intermittent!!

[Llanigraham]

Quite, which is why I think the dealer is being "lacking" in his response and why it needs to be escalated.

[Frenchtone]

agree!!

Once a DTC has occurred it will be stored, so therefore should be able to be read.

 

Get someone to scan the car with VCDS and go from there.

I  have the same engine but in auto. Today mine cut out suddenly. Would re-start but cut out when put into D or R. RAC mechanic blankedff the EGR and the car ran a normal. Got us to the Main Dealers. They've since phoned to say "no fault recorded". I'll post update when I know more.
