The DPF has reared it's ugly head again! I had the DPF removed and professionally cleaned and car was running reasonably for sometime with occasional 'bursts' of smoke out the back. However the engine runs ok, does not go into limp mode and according to scans has been carrying out regenerations when necessary. However, recently it has started to play up again and the dreaded DPF light cam on yet when checking with VCDS soot content was in range. Decided to carry out a Service Regeneration which initially was reluctant to kick in but then got it to do so. As you can see the regen was going according to plan with both soot content volumes reducing but the DPF Differential Pressure Sensor was sitting at 38hPa for sometime as the soot content was reducing, then that began going down very quickly down to 3 - 4hPA then suddenly, "BAM" it jumped back up and very rapidly shot up to 152 hPa and the soot content started to rise as you can see from the scans. But as the readings rely on the pressure sensor readings obviously the ECU thinks the DPF is blocked! I don't think it's the sensor at fault as I have fitted 2 or 3 over the time but now wonder if there is a wiring or ECU fault?

Further to this, have now carried out a VCDS Scan. Took it for a run out, thrashed it around a bit to get it hot and see what showed up.

Exhaust gas temperature sensor 3 is 130.0c: 1) cannot get this to reach 150.0c in anyway, would this effect the regeneration in anyway, as most information states exhaust temp to be +150.0c? 2) does anybody know exactly which sensor this is. Pre turbo, Pre DPF or Post DPF? Is the Oxygen sensor value about right?

Hi, posted sometime ago about DPF issues. Searched the forum but cannot find the posts as it’s a couple of years ago. Having had the DPF cleaned, off the car which showed the pre and post back pressure values, still having issues with the car pushing out white smoke after sitting ticking over or when undertaking sudden acceleration from a lower speed. Plus it still has the problem of (appearing) to try and continually regenerate once it has got up to temperature. Until then there is no sign of any smoke, nor when driving along. It has also had, throttle body replaced, oxygen sensor replaced and EGR valve replaced. Think it is pretty obvious that the white smoke is due to the additional fuel being injected when trying to regenerate and then being blasted out when pulling away? Have got VCDS and there are no faults recorded, although before the DPF clean the DPF light would come on, otherwise none. Would like some advice from anybody well up on VCDS what live data I should be looking at to try and find out what’s going on or anybody in Kent, UK that might be prepared to give up a bit of time to assist? I would point out that it had the software ‘fix’ before I bought the car and have considered getting it remapped to regress to the original or as close to as could be to see if that made addition. Chopping out the DPF and mapping it out is not an option for me I would add. Skoda Octavia Estate 2.0 TDI CR CFHC engine.

UPDATE*****UPDATE*****UPDATE I have now located some other units, from Audi A3's and VW Golf's which have the same prefix, 0CQ and the same part number 525010 with the only difference being the suffix? There is an H and L. My own view is that as long as the prefix and numbers are the same the unit will fit as the suffix and a lot of parts change over the years.

Had my rear diff diagnosed today, whine and metal filings in the oil! have located one on EBay from a 2017 Kodiaq which has the same 'numbers' as mine 525 010 but the letter codes are different, mine is 0CQ ...........F while the one for sale is 0BR.........M Anybody know if this would fit my Octavia 3 2015 CRMB 2.0 Tdi SE 4x4?

Hi, thanks for the input but definitely not the head gasket. It's been doing it for sometime and have been working through the components with a replacement EGR valve last week. No other signs such as oil / water mix, no increase in oil level or overheating.

My 2012 Octavia II 2.0Tdi CR 150 is producing white smoke from the exhaust and running at a fast idle, around 1000rpm, as if trying to continually attempt a passive regeneration of the DPF and think this may be causing it to over fuel pumping excess diesel into the DPF and hence the white smoke. Anybody who has seen my previous posts know I have had a long term issue with the DPF etc. However, after having the EGR replaced, the DPF cleaned recently and the turbo replaced a while ago this is still happening. I found an earlier post (which I can now not find!) regarding undertaking a run gathering live data through VCDS? I know when the turbo was replaced the garage had a problem with the oxygen sensor which they replaced at the time. I also had a replacement throttle body fitted bit it is not a genuine part. I have an official VCDS set up and was wondering what data I would be looking to get to check out the relevant sensors etc? When I have run checks on it before I have had doubts about both the coolant temperature, gauge indicates 90 degrees while VCDS logs 75 degrees. Similarly I think the Exhaust temperature readings are lower than expected but this is just a snap shot reading not live data. I have taken the car on long fast road runs to ensure it gets as hot as possible. Everything else, oil, water and power check out ok.

Appreciate all the replies and suggestions about the USB fittings unfortunately when it comes to these things I am a bit of a nerd. Also although it's a relatively easy job to convert the 12v supply to twin USB outputs it requires the storage to be open. Running the vehicle, as I do with all of mine, as a Private Hire (Taxi) service bet your bottom dollar that's going to get broken by one of the customers feet at some point. Believe me those rear bits are just ripe for people to mess with and break, had cup holders, arm rests and 'ski flaps' done in so the less that moves the better. The twin ones are a project for my VW Sharan & Seat Alhambra. Bought the Stop / Start panel that fits in the centre section of the lower dash panel, they fit in where the 12v & stop / start buttons fit, take a feed from the fuse board to them and there you go, all neat and tidy ready for all the gadgets that need to feed off them.

So, been having another root around to see what I can find about the USB set up. It seems that there is a "hub" connected to the infotainment system, Part Number: 5G0035953 (may come with various letters at the end, C, D, or X.) It appears to have a single input to the unit but with 3 inputs or 3 lines in through 1 input? If that is so then there are 2 additional inputs available. The part that fits in the centre console would appear to be: 5Q0035726 (again may come with various letters at the end, C, N, M and E, although the one ending in L appears to be a double one?) If you Google some of the part numbers they come up as Seat and visually look different. Not sure how you could wire them in for the minute as I cannot find a harness listed for them so may have to find a breakers where you could strip out the part of the loom you may require or get in touch with the local dealer and see what they can come up with? My thought is the plug on the unit end going to the USB sockets. As for the rear of the centre console there are 2 rear carriers listed and 4 inserts on zap7 so perhaps one of them along with one of the usb plugs is what I am looking for?

Had another look in the handbook and my original picture is not for the 240v installation? Had another look and this picture is for that so the USB fittment must be available somewhere?

There is always discussions on Cambelts / Waterpumps is it X miles or Y years, stop start driving v motorway miles? I run my cars for business and they are done every 100k all of them. Never had a failure (knock on wood) done by very good independent with genuine parts. Rather over service and avoid problems than skimp and end up paying a fortune.

Hi, I live in Kent around an hour away (TN17) would certainly come down to get it done for the £20. I have just added a 2018 SEL Executive to my small fleet so was going to ask about doing it with VCDS as I do have that but if as you say you cannot then sure just for the convenience and if it can be done on the key as well, like my Alhambra all the better.

Interesting topic for me as I have just purchased a 2018 SEL Executive for my Private Hire business and looking to put USB's in the rear both for their use and run an iPad with extra services on for them. In the handbook it does show 2 usb's fitted in the rear of the centre console. Obviously not sure when or in what model or even if they were an optional extra but have done a number of Google searches to try and find the parts involved with no success so far. Not having really got into it I was wondering if the loom was still in the bottom of the centre console for when the usb / phono was in there? Alternatively there is a 12v socket in the storage and I thought about converting that to a twin usb?

Waiting for the car to go into the garage to have a replacement EGR valve fitted and a check on the DPF as it very quickly 'blocks' and requires a very regular service regeneration and always appears to be attempting a passive regeneration, rise in tick over speed to approx 1000 rpm and fans continue to run after switching off. Last couple of times taken it for a good blast down the motorway then be able to carry out a service regeneration no problem, but if I just take it for a run around to get it up to temperature it's not so easy. Took a snap shot as it was regenerating earlier today and have a query about the Exhaust Sensors. It's a 2.0 Tdi CR CFCH engine. 4 sensors are listed, 3 seem to be well up to temperature while No 2 reads 0? Anybody know if this is normal and if it actually has 4 sensors? There are no fault codes listed on any scan done.
