So I'm just waiting for the Skoda Assist 'chap' to arrive as my Yeti's engine management light came on this morning.  Car runs and drives fine, no tickover issues, etc. Last time this happened it was a glow-plug issue, but maybe not this time.

 

I thought I'd remind myself where the ODB port is.  Down under the dash near the drivers right leg - yes? Except when I've just looked there I found a strange white plastic oblong thing with a red light in it shining where the port should be.  I've not pulled at it or anything.  The light on the 'thing' stays on even when the car door is shut (with the ignition off).  Maybe its been there all the while that I've owned the yeti (4 years) and I've never noticed it before (how unobservant is that?) while cleaning the interior and washing the mats and pedal etc.  But really?  The car was serviced (60,000 mile) a few weeks ago, and has done only a 400 miles max since then so I'm also thinking it's something the mechanic left in the port?  Anyway, Skoda Assist is due anytime now so I'll let you know, unless you can tell me before hand, that I'm a numpty  and it's always there :) !

There was no light in mine

Thanks for the reply Graham.  I can't believe I would have missed this white plastic light emitting object, as it's in such contrast to the rest of the dash and car's interior.  The 'light' is emanating from within the body of the 'object', on one side, resembling some illicit tracking device!  There are no serial numbers, leads or sockets, on it. 

 

S/Assist just phoned to say they'll be 30 mins or so - the suspense!

Mystery solved.  I'm not going barmy, (well the jury is still out, but not conclusively - yet) and there was 'a thing', a foreign object, plugged into the port.  The RAC chap pulled this out of it   https://caristaapp.com/

 

I assume it was placed there during the last service. 

 

Re the engine management light - as happened before, it was a 'glow-plug' issue.  RAC bloke thought that with the rapid drop in temp over the last 2 days (this morning it was -1 degree C up here), it triggered the light.  He's reset it, via OBD, and restarted the engine.  All seems fine, and the light hasn't come on again.  Fingers crossed.

 

 

Bonus. So if you download the Carista app, you will be able to scan for faults yourself

It should also work with VAGDPF* so you can monitor the state of your DPF

That's not something a Skoda garage would use.

Agree.  I use an independent Skoda Specialist, rather than a franchise Skoda stealership .

I had a reader/transmitter left in the OBD port when I took my Yeti in for MOT. The owner of the MOT station was very grateful when I returned his Snap- On piece of kit a few days after the MOT.

Yes.  I've been using the garage for many years now, having bought my first used Octi 4x4 1.8T from them, and they've serviced my two yetis and my partner's last two Fabia's.  I rate them very highly and they've been more than helpful and fair with us.   It'll definitely be sent back to them.

My garage left their Tapley Meter in the footwell of my last Yeti when I took it in for it's MOT.
They were VERY grateful when I took it back.

If it was an old school 1960's one then they would have been kissing the ground that you stood on, they are allowed to retain & use the old units as long as they are calibrated but if they have to be replaced they can only use a new and approved bluetooth communicating one which costs a fortune to buy and have calibrated.

 

As a consequence the old ones are worth a fortune.
