Hi all,

First post, please be gentle :-). Need some help and have a couple of questions.

I picked up my 57reg Octavia last week, and I had the engine warning light on twice. Once on the second day of ownership, the second on the 7th (today). Yellow coil thingy on the dash. :-(

Both times, engine went in limp mode, but no other signs that there is anything wrong. I pulled over, switched the engine off, restarted, then everything was fine again and I continued on my journey.

Just rang Skoda assistance, and apparently, unless a fault is showing, they cannot do anything whatsoever. Is this the case? Does the ECU hold a log of error codes, even if they are not showing at that moment? Can an RAC mechanic read these?

I need to do a 170 mile trip early tomorrow and I don't want to risk it.

Many thanks in advance.

:-)

The ECU does hold a list of all the faults recorded, skoda assist should be able to read them.

Hi sv2evo , i had a similar problem with my vRS diesel with the engine management light , i called the RAC out and he plugged in his laptop which showed 2 x faults up straight away so i presume it does store them in the ECU , when the RAC guy explained what had happened basically he said that when u first turn the ignition on the ECU receives data from loads of sensors around the car , if it does,nt get the data from a particular sensor quick enough it will throw up the fault (i.e engine man light)

By the way the RAC guy reset my 2 x faults , went to the dealers few days after no more faults but they replaced the pressure sensor due to a recall

My 2 x faults were "Exhaust Pressure Switch" & "Central Convienience Unit"

Hope this puts you at ease abit

Many thanks for this. Did your faults occur while driving or before you set off? Were the faults active on the dah when you called the RAC assistance?

Call your dealer and find out if the recall has been done for the Exhaust pressure sensor and EC U remap. Even if your car was bought private or from non-skoda they should know.

Yep the faults were on the dash when the RAC turned up , think they happened as i set off to drive (with a minute of starting the car up)

The VRS TDI PD had a couple of updates, the first was the 28E1 and the last one the 26E6.

They both had to do with the DPF problems. The first one was a motorupdate only, the second one a motorupdate and change of the exhaustpressure sensor (the one that controls the pressure before and after the filter (differenzdrucksensor in German)).

Another sensor was changed before modellyear 08 (all cars before summer 2007). It was the relais that controlled the glowtime (vorgluehzeitsteuergeraet, dont know what it is called in english).

If all these updates are done (not a recall, as these things are done if you are at the dealer for service or intermediate troubles), there shouldnt be anymore faults.

When I bought the car, I asked specifically about recalls, and they said they will do the one outstanding. The sticker informing you of the recall being done in the boot floor next to the spare wheel is there so I assume they have done it. I assume that's the exhaust pressure sensor. I will book it in with a dealer just to make sure...

Many thanks to all that responded. Much appreciated.

Been to Skoda this morning. Apparently is the turbo pressure something or other? Booked it in for Monday.

Is it a common fault? The service guy said he does not think it is?

Sounds common, had it also a couple of times. Untill they sorted it out with the pressure sensors.

That is about one and a half year ago (probs until my first service at 30tkm, having driven almost 100tkm now).

If they are saying it is turbo related (too much pressure as the revs build up over 2,000; causing limp mode) it could be sticky vanes in the VNT turbo. This is another common fault. If you do a search you'll find lots of info about it. If you are covered by warranty they often just whack a new turbo in, but if you have to pay for it then freeing up the vanes is a MUCH cheaper solution.

Covered by warranty, the car has 1900 miles on the clock... I can understand a faulty sensor but a new turbo at that mileage would be a disgrace.
