Default Octavia vrs

I bought an octavia vrs last week it had full service history last service last month all done at the main dealers receipts to prove new tyres all round suspension all done in August no rust anywhere proper clean it is. The engine light was on and the oil light the oil light is a sensor and the part wasn't in stock I got told the engine light was on due to it been mapped? I wasn't sure and haggled £350 off the asking price so was happy enough and done a deal the car was boosting well etc and I am waiting to get it checked. I went to buy the car myself after work and ended up leaving my van on a near by street from where I bought the car later on I picked up a mate and went to get the van.

He wasn't insured to drive a van on his policy but could drive the car I know for a fact he never ragged it as he stayed behind me the whole way back when we got back he said he had stalled the car but he liked it everything felt good to him etc and he may consider looking for a clean one etc when I got back into the car the next day I noticed it had lost power it still boosts but not even half as much as it had previously as said I don't blame my mate as I know it was driven with care. I went to msd today but there well busy and can't look at it until end of November so was wondering if anyone had any idea what it could be?

If there is anyone in blackpool area that could look at it or let me know where I could take it that would be a bonus.

I have found no receipts for a re map how would I tell if it's had one possible explanation I was offered by msd for the light was the receptionist said having been recently serviced they could of updated the ecu which would wipe the map and could cause the light to come on! Makes sence to me so whilst I want to book it into msd I would like the issues I have sorted in the mean time any advice would be much appreciated

If the light is on you need to get the codes read and go from there.

Get yourself VCDS it's well worth getting, even the free version so you can check stuff yourself.

MAF sensors, coil packs, air leaks from PCV system are all common faults on them.

http://www.ross-tech.com/

http://www.ross-tech.com/vcds-lite/download/index.html - free download, for cheap cables (eBay) can do basic code reads and live data.

(limited measuring blocks)

Cable - http://www.ebay.co.uk/itm/VAG-GROUP-...item3f1b0d351a

If you have the free version and it works on your car you can pay a $99 dollar license fee to unlock more features etc.

If the oil light is because of the level sensor, check the fuses, these can sometimes blow causing the fault.

I've also ordered uprated boost pipes as the standard ones are restrictive apparently and prone to failing

Had similar problem on my Focus RS a couple of months ago, a mate put his diagnostics kit on it and the error code led us to 2 main possibilities, pre-cat lambda sensor or split hose. Because it was still driving fine we first changed the sensor but within a few miles the engine light came on again and the driving became more erratic with the idle becoming more and more lumpy, then i could hear a hissing noise when it was ticking over on my drive and i managed to trace the hose that had a large split in it causing the hose to collapse on itself. We changed the hose and it's been fine since so i would check your hoses to see if any have split.
TBH i know bugger all about Octavia VRS engines but i presume the basics are the same so you never know, it could be a similar problem as i had.

I hope it is as simple as the hoses as I was advised to change them as they where restrictive and prone to failing. I won an eBay auction for some new uprated ones glad you got yours sorted. There is no smoke so hoping it is an easy fix

Oil light often means a blocked oil pick up strainer. Can be an engine killer.

It's been in for a service says on the sheet it's a sensor the part wasn't in stock and the guy never went back for it resolved I've got one on order should be getting done tomorrow the car isn't really getting used at the min till I get these issues sorted as I have a van also and would rather not take the risk. Would this problem you suggested come up on a diagnostic?

i had a vrs and as already suggested blocked up oil pick up strainer is very common on these.
i would not be driving it or starting it until the oil light issue is resolved,hopefully it is the sensor but it could well be a blocked strainer.
its a cheap and easy fix as long as you have not run it with oil not getting round the engine.
if the sensor does fix the fault and you plan on keeping the car i would get the pick up pipe changed anyway.
also coolant temp sensor, water pump,thermostat and cam belt failures,all common faults.

I used to have a mk1 vRS lastyear and all of the above is correct.

As mentioned before. Oil pickups are prone for blocking on higher mileage engines, you saw the odd one on the forums suffering from this.

My MAF sensor went while on WOT and went with a massive bang! (Engine jolt)

Secondary air intake pumps split easily and cause a "jet engine" noise on startup

Oil breather pipes under the inlet manifold are prone to splitting

Boost pipe connections are also prone to leaking boost.

Coil packs are prone to break down also and will cause a fault with dodgy running. There is a recall on these at the moment where skoda will replace these for FREE if your car hasn't already had the recall. Phone your local dealer and give them the reg to book it in!

All in all tho apart from the above, cracking cars and i still miss mine. Very underestimated by many!!!!!

Coil packs where done last month along with a full service and it had a partial strip down to fix a rocker cover gasket leak it says on the receipt the oil light was on in the service due to a sensor and wasn't replaced at the time as it wasn't in stock and the owner wasn't willing to wait I have one ordered but will get it booked in for a full diagnostic just incase cheers for the info

I'm not sure why it had lost boost not totally gone but I'm guessing that will come up on the diagnostic also

as already stated, the oil strainer & pick up pipes block, even if this is not the cause you need to drop the sump and do this anyway. It will save your engine.

the sumps are so easy to drop on the mk1 vrs, just one sensor to unplug and you can drop the sump, no need to move anything or take anything out the way first.

Apparently from what I read online when you change the sensor that is getting the blame for the problem you loose the oil anyway so I'm going to get them done at the same time for piece of mind and to also not risking the engine or risk loosing the oil twice lol cheers for the advice mate much appreciated
