Hi I haven’t managed to solve the problem. I am hoping someone else on the forum might have some ideas. Recently I personally checked the power to the fuel plug. When car is on it gets 14v on one pin and 1.7 on the other pin. This should mean the wiring is ok. The resistance of the fuel pump solanoid is 1.8ohms (measure across the pin) . Apparently this is within tolerance . My Research still suggests the replacement used fuel pump I bought is faulty. So it looks like I need to get a new replacement pump. I can only find cheap import fuel pumps for £70 to £90 (unbranded I think) Anyone suggest what else’s could be wrong or which fuel pump to buy?

Hi all problem solved. I did the rolling start and it still chattered. We got the starter out and tested on the bench. Our theory was correct sticking bendix not retracting fully. No real damage to the flywheel luckily as I didn’t drive it. Bendix was pushed in by hand then tested. I have to shorten the clip to get it under 10mb. I hope this helps other Skoda owners in future IMG_3617.mov

Bolts all tight and secure, as starter motor been fitted and running ok for 7 months. I read another test that I could try is a rolling start to get the car started without engaging the starter motor. Roll car with key inposition 2. It says this will 100% rule out starter motor if the chattering is still there. Only problem if I park in cramped road 😔 What do you think ? A decent test? Also I went to try and remove starter motor and my socket set doesn’t have 18mm, it seems to skip that 17mm to 19mm. Talk about bad luck

I got time to remove the thick black wire from the starter motor, then turned on the car. I heard the click then clack which suggests the bendix is moving. Yesterday I did the 12v ignition lead test and that seems to working correctly, only providing power when turning the key to get engine running. It could still be a dodgy starter motor ? Here is a video of the chattering sound. IMG_3602.mov

I am not sure if this can degrade the starter motor but when I heard the grinding noise for the first time, I popped the hood and was listening. I could then smell electrical burning and saw light puff of white smoke. So points towards overheating starter as it rotates too fast being stuck.

Original one died as this is what RAC diagnosed last year. Then I had a local mechanic check and they put a replacement starter motor in. They sourced it form Autoelectro which looks to be a company that reconditions starter motors. I have not looked at the relay which I think from research online is under the driver or passenger dashboard. The relay in the fuse box engine (no 100 written on top ) is not the starter relay

Thanks I just posted above to say I checked and there no continuous 12v being fed to the starter motor once the car is on. I am just a bit puzzled that a new starter motor (reconditioned Autoelectro ) which was installed 7 months ago has malfunctioned ☹️

Thanks I will give this a go. Early this morning I managed to find my circuit tester lamp and I checked the 12v plug to see if it goes to 0v once key back in position. Good news is, I think the electric 12v to the starter motor is working as it should. So we know the starter motor is not getting 12v continuously

Thanks for replying. Just to clarify So I disconnect the thick cable from the starter motor and then try to start the engine If the engine starts and I hear the grinding that means the bendix is stuck out . Have I understood right?

Hi all My Skoda 1.6 fsi 2006 petrol has an issue with the starter motor. It could be mechanical or electrical and I need any advice you can give m. Today I noticed a horrible grinding noise after start up. After researching the problem I discovered it is the bendix either staying jammed out against the flywheel or not retracting once the car has started. Does anyone know how to find all the relays? The only relays found was in the engine bay (no 100) The Skoda manual only has fuse locations. Anyone have advice on what else to test as the problem could be electrical. Many thanks in advance

Thanks for the information It is a difficult sound to explain, it is almost like a continous zip being pulled closed. I was thinking could be timing chain as it is an FSI engine? Or could it be the tappets like in the old days but that is more of a constant sound.

Hi All I assume the lambda sensor is at the front of the engine (pre cat). Is this correct, as some Octavia models have the lambda underneath the car. Also how do I unclip the sensor? Is it by unclipping the plug to the right of the sensor plug? Thanks

I noticed an intermittent rattle, that comes and goes whilst the car is idling or driving. I have searched the forums and YouTube and it could be the timing chain or a pulley on the S belt. Anyone know for sure or experienced this before? Short 60 second clip of engine rattle

Anyone got experience with this issue and fixed it? struggling to see how I can get access . kind regards

I think I have a problem with sun roof drain pipe. I discovered a lot of water in the driver footwell. I dried the carpet and pour water in the sunroof trap to test it, and the footwell was wet again. Water is not coming out of the water pipe outlet? (See picture) so i assume the drain pipe is not connected. Does anyone know how do I get to the inside of the drain pipe connector? Is access from the wheel arch? Or elsewhere ?

Hi all I have an Octavia 1.6fsi 2006. It has been a great car with minimal issues until this year. The exhaust warning and EPC both came on a few months ago. With a cheap ODB reader, it pointed towards fuel pressure regulator 08853 error. The car was running, but would run lumpy at times and fuel efficiency was down. I could smell excess fuel sometimes from the exhaust. I bought a used HPFP and cam follower. The original cam follower was not worn through but I replaced it and put in the used HPFP. The car ran better and fuel efficiency had improved. However the exhaust and EPC lights were still on with N276 error still occurring. Car was fine for a few months but on the motorway last week, the car lost all power, accelerator did nothing, so I carefully pulled over. Car was spluttering. I turned it off, waited a few minutes then turned it back on and everything seemed ok and I continued on slowly to get home. I have now had the car scanned with VCDS. 6 faults were found, pictures below. The main one being 000853 - Fuel Pressure regulator valve (n276), p2295 - 002- short to ground - MIL ON All faults were cleared then the Car restarted, the n276 short to ground fault came back. The engineer checked the wiring and found f23 15A fuse blown. This was replaced. Cleared faults, restarted car. N276 fuel pressure regulator reappeared but now says Short to Plus. (Picture below) Engineer thinks the used HPFP also has a faulty fuel pressure regulator, as it has to be the most likely reason for the fault to still appear. We checked my original HPFP by plugging it in and the same error appeared. I suppose it is bad luck that the used HFPF has the same problem. I may have to just buy a new fuel pump which is around £300 but if it doesn’t solve the problem, then the new fuel pump was not needed. Has anyone got any other advice or anything else to check? Is there a way to test the Fuel pressure regulator with a multimeter somehow?

Anyone got an update on this? my 1.6 fsi lost power today on the motorway cruising at about 65mph. Accelerator pedal didn’t work, I managed to pull over safely. With the car idle, it sounded rough. I turned it off and waited a few minutes. Turned car back on and it seemed ok. I continued on and it didn’t happen again. I will look to get it plugged in, to see if there are any codes

An update for anyone who has the same issue in future I replaced the fuel pump this weekend. A straightforward job if you have the correct tools like size 14 fixed head spanner, jubilee/retainer clip clamp to remove clip safely and socket set. Took me 1hr15min, with a few stop starts and videoing some of it. In terms of results, car feels better and not lumpy however not driven it for long enough. Also mpg seems higher but again I need more days to check this properly the EPC error code 8854, fuel regular circuit high is still on. my next step will be cleaning the throttle body with throttle cleaner.

This week I tested all grounding points I could find as the latest error was fuel regulator short to ground. all grounding points tested ok and gave the same reading as the battery (12.10v) any suggestions on what check or change? I have read a lot of posts where owners have changed fuel pumps and a lot of sensors but it still didn’t cure the problem. Car still runs, except it is using a lot more fuel (15% to 20% approx) and occasionally is lumpy on hard acceleration.

Did you solve the problem? I have had this error come on occasionally but the main error for my Skoda is fuel regulator valve low circuit or short to ground. I have checked the grounding points I could see and all test fine (12.10v like the battery )

Hi all stick not fully sorted. plugs, air filter and fuel filter changed. car more responsive but I have still epc and emission error, with the main error being fuel regulator anyone know if the fuel regulator is part of the fuel pump on the 1.6 FSI? any help much appreciated

I have had a look at the fuel pump and I can’t find the fuel sensor. there is a sensor on the pump but the other rail sensor isn’t located in the same place as other fsi engines, usually to the left of the pump. my engine is the BLF and I think might be under the manifold I am going to have to get the garage to have a look and recommend what options to try and fix the error code and excess fuel consumption. picture of the BLF engine 1.6fsi

I don’t know about what mods that car has. To me car looks good from the photos and with my Octavia I like cruise control, rear sensor and auto wipers/lights are so handy. my only question would be is the engine belt driven or chain? If it is belt, when were they last changed as you might need to do then sooner than later. I am not sure how much it would cost to do but I expect all belts and tensioners to be expensive so budget £500. Other On here might know more and have better advice

Did you fix this and what was it? was it the fuel sensor?

My 1.6fsi had the EPC and emissions warning come on. I bought a basic VAG reader (ancel vd500), the error codes were 08854 fuel pressure regulator control B control circuit high 08851 Fuel pressure regulator B performance The car idles a bit rough and occasionally when accelerating hard, the car can fill chocked and not smooth. also there is occasionally an external smell of excess fuel Any ideas on what to change/fix first? Is it the fuel regulator or fuel sensor? I saw a video where a mechanic said the mini container bucket under the fuel pump can corrode (solid bottom disintegrates), this affects the fuel pump performance.
