YES I totally agree. These dealer franchises are a law unto themselves, they are so PROFIT orientated with little real customer focus and are ruled by factory workshop shedules rather than actually fully investigating causes of faults.

In our household there's been a Seat Ibiza, VW Tiguan, Audi S3, Skoda Fabia, and I still have my Octavia (1Z3 1.6 TDi The Seats' ignition barrel siezed was replaced and the replacement fell to bits and so was butchered further to enable the key just turn the starter. The Tiguan 2 litre TDi Haldex had to be replaced MEGA Money and the ugly swirl flap motor problem reared its ugly head twice and the massive fuel consumption as result of the failures never got any better. The Audi S3 was just old but its' problems were persistent CV joint failures. The Fabia estate, well, the front brake discs and pads seemed to collect debris in an alarmlingly abnormal way resulting a complete siezure one day of the calipers on both front brakes. It had an air con condensor radiator perforate simply because it's so low to the front of the car stones could just fly straight at it past the plastic grilling. It's front passenger door wiring loom broke where it runs through the rubber boot in the hinge and the vinyl sticker trim just peeled away making the car look like a torn rag. My Octavia, ooh where do I start. 4 rear wiper motors, replacement air con condensor and compressor, two EGR valve replacements two complete sets of injectors, 3 ABS wheel sensors ( 2 on the same wheel in less than 6 months). A failed LED light in speedometer, a failed oil level sensor on the sump, a failed drivers door window actuator / motor whatever VW wish to call it. The latest saga was the DPF system not regenerating after three thorough strip downs and cleans which took a local independent workshop with specialists to find out what VW never bothered to tell me about and that was ECU updates being required because new injectors fitted after the emissions scandal and the VW ' tweeks' meant my car was SIX ECU updates out of date which they promptly sorted for me for less than £200. The worst one for me was the problem with my Octavias heater blower motor system which I posted about on here where the dealer refused to check when I asked but therefore missed the chaffed wire shorting out on bare metal behind the dash which would have eventually resulted in a fire. That again was resolved by an independent VW specialist. All of these cars were / are properly cared for and were dealer serviced regularly. One expects things to go wrong occasionally but this takes the pi**. Why we persisted with VW brand cars leads me to think we need therapy. My wife bought a Toyota Corolla Sport estate trading the Fabia in and getting a fantastic deal. Two and a half years on NOTHING has gone wrong whereas a lot of the problems with other cars occured within 18 months of ownership. The Octavia is currently driving with 'No faults registered' on the OBD. We're only one month on from the ECU update though and I'm not expecting to cover much mileage before the next problem. I've lost interest in really trying to look after this car now and I'll run it into the ground and then torch the bl88dy thing.

Thats interesting to see the calculated soot content is almost the same that mine was at. My system was ignoring the actual soot content (zero) and still showing the pre flushed content of 35g until the ECU got reprogrammed. I hope you can find a good independent VW group specialist or workshop with dealer level diagnostics I have no faith in my franchised dealerships locally. Don't bankrupt your self on replacing anything until the ECU is interogated.

Hello bazza1827, I have posted a separate "essay" about my DPF problem ( strange DPF problem). I spent weeks scanning, removing and flushing DPF, and changing egr valve (twice). DPF light would just not turn off despite having done all the correct things. Out of curiosity have you ever had any injectors changed because a injector failures? I had previously changed a couple of injectors then very recently replaed the whole set. The effect of this impacted the dpf regen function or rather didn't. A workshop with dealer level diagnostics found my car to SIX ECU software updates out of date. Skoda having had multiple issues with the Siemens injectors have been putting in software updates to change the injector fuel delivery map. My Injectors had triggered the DPF regen program to cancel because despite putting in the correct adaptation codes the old injector map remained in the ECU stopping the regen from commencing. These engines rely on extra fuel being delivered into the cycle to help burn off the deposits and regen the dpf. Kudos to the workshop that reprogrammed my ECU and got the dpf to regen and extinguish the light. The dpf after I'd flushed it out was in fact almost zero soot but the ECU wouldnt have it because of the new injectors not matching old ECU programme and cancelling the regen. For less than £200 I've avoided a bank raid to afford a new dpf.

Hi Thocar, I have just come back onto the forum to share my knowledge and recent experience. My DPF issue:- May 2024 dpf light illuminates. Take car on recommended 1500 -2000 rpm 30 minute drive. Dpf light goes out. 1 month later dpf light come on again. Continue driving to regen the DPF but instead coil symbol light appears as well signifying a possible EGR fault too. Car goes into limp mode. Got car home. Jack up and support car. Drop subframe and remove dpf and flush it out with Wynns. Replaced EGR valve. This is a pig to remove only because of where the bolts are that mount it onto the back of the engine. Reassembled everything. EGR light goes out for 5 mins then returns. DPF remained on. Removed EGR again ( it was an aftermarket brand ) Put a genuine VW one on. EGR light gone and remains off. DPF light still on. Two long drives still not reset and regened. Took dpf off again when diagnostics said soot level still high. ( 35g soot ) Second flush out. Reassembled. Had a quick Garage workshop check of the system who noted erratic injector values. I had replaced a couple of injectors previously 24 months earlier. Seems they were all on the way to failing so replace the full set with a German company reconditioned set. Made an amazing difference to the running of the engine but DPF light still on despite scans showing NO faults. After scratching head raw thinking why not regenerating had a local diagnostics technician with dealer level equipment. the answer was ;- my car was SIX software updates out of date. I had done all the right things which under normal circumstances would have reset the DPF regen cycle. Since VW have had lots of problems with the Siemens injectors there had been several ECU software updates to deal with the problems. My newer injectors had triggered the ECU software to stop the `DPF regeneration cycle on the revised injector values despite them being programmed in with the correct adaptation codes as the ECU software was out of date for the injectors. After weeks of half crippling myself under the car on the drive the problem was electronic.MY dpf had in fact been cleaned out to almost zero soot but would not allow the dpf regen cycle. So question, WHY DOES SKODA NOT INFORM OWNERS OF REQUIRED SOFTWARE UPDATES AS A MATTER OF COURSE? I saved a couple of thousand pounds on not getting a new DPF which is what Skoda quite likely would have told me to get. and then update the software. How many owners out have a dpf light that will not go out despite all attempts to clean it and get a regeneration. Consider the software issue. My fix was eventually less than £200 to sort out.

To Michebelle, my iphone just pinged with your message from this forum. Firstly. this section is for the Octavia Mark 2. My car is a TDi MkII facelift so I think straight away your posting on the wrong section. Your photos are of no use to me if you have a Roomster Scout. I don't know where the blower motor or its ancillary electrical items are on your car and the fuse panel bears no resemblance to an Octavia one. Have you read my full postings and viewed my photos of the cause of my blower fan problems ? Suffice to say that on my Octavia nearly everything except the wiring behind the dash panel is easily accessible and I was lucky in that I could afford the time and effort to have my car off the road for a couple of weeks while the fault was discovered. Either be prepared to perform an extensive strip down of the dash to get to the wiring to do a comprehensive check of the blower fan circuits or take it to a local reputable independent VW group repair and service workshop that has factory trained technicians and the up to date VCDS. Don't rely on Franchised dealers to investigate your fault, I have lost faith in the VW workshop schedules which the mechanics are tied to and they do not do what you ask from my experience. Sorry I cannot be of more help with a Roomster.

Just tagged onto this topic. Sounds like my ordeal a couple of years ago when my blower fan resistors kept blowing. Look at my posts. Because my local dealership faffed about they missed the one thing I asked them to do, ie check the wiring loom as I had covered all other possible causes of the blower fan failure. A local independent VW group specialist workshop found the chafed wire behind the dash which was drawing a huge current through the resistor to earth. I posted a photo of it. Good luck in finding your fault and fixing it.

Thank you 3T51704X4. Strange coincidences the way things work out. Although I had practically answered my own questions about my fuel sender problem following a drain down and refill after misfuelling. Also shows how those who think they are quite knowledgeable can fall foul of their own confidence. After refilling with the correct fuel (diesel) and replacing the fuel pump/ sensor can this last week I have had fault code B103E12 intermittent and finding that switching off the ignition and then restarting the fault would clear. I was convinced that I had somehow disturbed the connections on the fuel sensor resistance track by leaving the tank with petrol in it overnight before draining it and have ordered a new pump/ sensor unit. Tonight I was musing through ebay and noticed the the used pump sender units that had just had the fuel lines cut through instead of disconnected when I realised I have put my fuel lines back on the wrong spigots. Sure the car ran fine until doing a hard right turn up a local hill ! I have rushed out to the car and repositioned the fuel lines. Have driven 25 miles without issue. The car even drives and feels far smoother. There are no stored fault codes. It would appear that mis placing the fuel lines on the pump unit allows the container the sensor sits in to get pumped dry or so low that the sensor track does not sit immersed in fuel which must affect the electrical resistance of the track hence B103E12 'Fuel sensor resistance too high' Someone may correct me if I'm wrong on that one but I don't mind being subject to howls of laughter even if I do have a B/TEC 1st in Motor Vehicle Engineering !.
