An update on the topic for you, it has been a whole week since the body was cleaned, and I've done a fair bit of driving in that week, in traffic with the stop/start performing absolutely brilliantly, not missing a beat, stops instantly with no rough shudder and starts the same way. Power delivery is also perfectly smooth when pulling away from stationary, and the idle is once again nice at 800rpm. So the video I found on YT was correct and also a big thank you to DEL80Y, it really was just the throttle body that needed cleaning.

If you run the cable down the A pillar and into the fuse box, you can pick up the feed and earth there, but be aware that the dashcam uses 5v, not 12v, so you will need a convertor,

Check the fuse, if they both stopped working at the same time, it has to be something they have in common and might be the fuse.

I have had my throttle body cleaned by a local garage (Trinity, in Springfield Road, Chelmsford) and I have to say that they have done a good job, originally estimated an hour's work but due to a stubborn bolt it took almost 2 hours. The car is actually smoother on take off now as before sometimes it would snatch a bit and also the engine is idling around 800rpm, before it would fluctuate between 800 to 1000rpm. I'm also noticing that it gets into 4th gear a lot more now during town driving at speeds of 25mph, before it was nearer to 30mph, so fuel economy should be better as well. Time will tell on that front. When I went to pick up my this afternoon, I was pleasantly surprised when I was informed that had a couple of photos for me to show what they found on removal and another showing how clean it was when they refitted it, I attach these below, and I'm amazed at the state it was in and can see why the OBD2 error report said that the body was giving an implausible reading, the gunk was preventing the flap from sitting correctly and thus giving the ECU an input that might suggest the engine might run at too high rpm if the start/stop system were to start the engine and the car shoot of at unexpected speed? Does that make sense?

This morning I had another request from Carista support to do yet another scan of the cars ECU's and send them the report direct from the app, this what the scan produced, the same as before, no errors on anything apart from the TV Tuner, which despite throwing out these error codes, is actually working. I look forward to getting their analysis of the codes back in due course.

Well my Superb is still on its 2nd set of pads from new, has almost 79000 miles on the clock and nearly 10 years old so if don't drive a boy racer with the pedal to the metal until the last minute, the cars natural compression braking works just fine with the DSG automatically down changing to assist the braking effort. You will also benefit from increased MPG figures and that in todays climate is a positive and also helps to lower emissions.

I'm just curious as to why anyone would want to change down from 2nd to 1st, even for engine braking. I find that there is enough braking effect in 2nd as the car slows down enough the DSG will automatically select 1st anyway, even in manual mode, the down shifts happen automatically to prevent the engine labouring.

Car is booked in on Friday to have the throttle body cleaned so I'll be able to report back if that was the problem or not after a couple of days driving. Some days the start/stop system perfectly, then the next it cuts in a couple of times and then it stops and produces the error code and I have to start manually. The error code 05286 is just a freeze frame of the engine data at the time the error P0121 occurred (Throttle body), this the information provided by Carista after sending them the report direct from the app. 05286 – Freeze frame Priority: 2 Malfunction frequency counter: 3 Unlearning counter: 255 Odometer reading: 126448 km Engine rpm: 0.00 RPM Normed load value: 0.0 % Vehicle speed: 0.0 km/h Coolant temperature: 59 °C Intake air temperature: 17 °C Ambient air pressure: 1020 mbar Voltage terminal 30: 13.000 V

Shouldn't be voltage problems, its a brand new battery and the glow plug was again flashing yesterday and plugging the OBD2 in, I extracted the for fault code 05286 and sent it to Carista for more info, the voltage recorded was 13.00V.

Oh, OK, so does anyone know if that is true for the Superb?

I realise that this is an old thread, but I think the warning light is nothing to do with the wheel speed. It is a battery powered sensor built into the actual tyre valve and these batteries typically last around 5 years on average. The battery is not replaceable and if a car has a tire pressure warning light on the dash, when having an annual MOT test, then it is an automatic fail. The cure is go to a tyre shop and have them fit a new valve in the wheel(s), I have no idea of the cost, however.

I just did a Google search for the P0121 error code and I discovered this video. https://www.youtube.com/watch?v=68pFKbhA47s

I spoke too soon, the problem came back again yesterday with the Glow Plug symbol flashing all the time in the instrument cluster. I plugged the OBD3 tool in and scanned the ECU's for codes and got this result. Basic OBD2: P0121 (Pending) - Throttle/Pedal Position Sensor/Switch "A" Circuit Range/Performance CAN network gateway: 00467 - TV-Tuner (R78) Engine: 05286 ABS: 02214 - Tire Pressure Warning Navigation: 00467 - TV-Tuner (R78) Radio: 00467 - TV-Tuner (R78) Obtained with Carista 7.1 for Android. Today it has performed flawlessly. Any thoughts?

Since managed to get the battery details entered into my ECU, I have not a repeat of the problem, maybe it's just behaving itself, or maybe it's fixed, time will tell, I'll update this thread if I have any problems.

I did manage to get the battery coded to the car OK this afternoon, then I did a diagnostic scan of the car, scanning all 27 controllers with no fault codes found. Then I did a detailed report on all the controllers and I get this report: ECU info obtained with Carista 7.1 for Android: VIN: TMBBF73T9E9021678 CAN network gateway Part #: 7N0907530AL Component: J533 Gateway Software version: 1642 ASAM/ODX identifier: [none] Coding: 353303 (hex) [No fault codes] Engine Part #: 03L906018RQ Component: R4 2.0l TDI Software version: 9977 ASAM/ODX identifier: EV_ECM20TDI01103L906018RQ Coding: 001D0032042501080000 (hex) [No fault codes] Transmission Part #: 02E300062A Component: GSG DSG AG6 Software version: [none] ASAM/ODX identifier: [none] Coding: 20 (decimal) [No fault codes] ABS Part #: 1K0907379BL Component: ESP MK60EC1 Software version: 0152 ASAM/ODX identifier: [none] Coding: 863D6016092400FB611106EB90210092350150 (hex) [No fault codes] Power steering Part #: 1K0909144R Component: EPS_ZFLS Kl. 196 Software version: [none] ASAM/ODX identifier: [none] Coding: [none] [No fault codes] Steering angle [ECU not present] Steering wheel Part #: 1K5953521AK Component: LENKS.MODUL Software version: 0140 ASAM/ODX identifier: EV_SMLSNGVOLWSXS Coding: 0882140000 (hex) [No fault codes] Airbags Part #: 3T0959655D Component: J234__LDM VW10 H Software version: [none] ASAM/ODX identifier: [none] Coding: 17485 (decimal) [No fault codes] Instrument cluster Part #: 3T2920941M Component: KOMBI Software version: 0811 ASAM/ODX identifier: EV_Kombi_UDS_VDD_RM09 Coding: 410E01 (hex) [No fault codes] Navigation Part #: 3T0035686C Component: RNS-MID Software version: 5274 ASAM/ODX identifier: ------------------------- Coding: 04060002000000A11000 (hex) [No fault codes] Radio Part #: 3T0035686C Component: RNS-MID Software version: 5274 ASAM/ODX identifier: ------------------------- Coding: 04060002000000A11000 (hex) [No fault codes] Sound system Part #: 5C6035456A Component: KonzernAmp10K Software version: 6813 ASAM/ODX identifier: EV_AudioVerst10KanalBNO1 Coding: [none] [No fault codes] TV tuner Part #: 7L6919148A Component: R0078 TVhybridDV Software version: [none] ASAM/ODX identifier: [none] Coding: 3 (decimal) Fault codes: 00464 Controller with display unit for radio and navigation (J503) 01299 Diagnostic Interface for Data Bus (J533) 03210 Video Connection red 03211 Video Connection green 03212 Video Connection blue 03213 Video Connection sync Telephone Part #: 3C8035730D Component: Telefon Software version: 0946 ASAM/ODX identifier: EV_UHVPremi Coding: 020100000100010000000101 (hex) [No fault codes] Immobilizer Part #: 5K0953234 Component: IMMO Software version: 0811 ASAM/ODX identifier: EV_Immo_UDS_VDD_RM09 Coding: 000000 (hex) [No fault codes] Headlight aiming Part #: 5M0907357F Component: AFS-ECU Software version: 0111 ASAM/ODX identifier: EV_HeadlRegulVWAFSPt Coding: 01C600003F000000 (hex) [No fault codes] Heater & air conditioning Part #: 3T0907044CJ Component: Climatronic Software version: 0709 ASAM/ODX identifier: EV_Climatronic Coding: 0010080003 (hex) [No fault codes] Parking/steering assist Part #: 3T0919475D Component: PARKHILFE PLA Software version: 0005 ASAM/ODX identifier: EV_EPHVA2CAS46X0000 Coding: 149301 (hex) [No fault codes] Central electronics Part #: 1K0937087AN Component: BCM PQ35 H+ Software version: 0779 ASAM/ODX identifier: [none] Coding: 46990A26EC7BF1C0500800C171008DEC0F7000CD63208760E280C7040041 (hex) [No fault codes] Body/convenience system [ECU not present] Driver's door Part #: 8X0959793H Component: TSG FA Software version: 0415 ASAM/ODX identifier: [none] Coding: 011D0220DE01001000 (hex) [No fault codes] Front passenger's door Part #: 8X0959792H Component: TSG BF Software version: 0415 ASAM/ODX identifier: [none] Coding: 011D0220DE01001000 (hex) [No fault codes] Rear left door Part #: 8X0959795D Component: TSG HL Software version: 0415 ASAM/ODX identifier: [none] Coding: 010C00200001001000 (hex) [No fault codes] Rear right door Part #: 8X0959795D Component: TSG HR Software version: 0415 ASAM/ODX identifier: [none] Coding: 010C00200001001000 (hex) [No fault codes] Driver's seat Part #: 3C8959760E Component: Sitzmemory Software version: 3001 ASAM/ODX identifier: [none] Coding: 00003B (hex) [No fault codes] Battery regulator Part #: 7N0907534 Component: Batt.regelung Software version: 1642 ASAM/ODX identifier: [none] Coding: 030F185A (hex) [No fault codes] Any idea what the highlighted fault codes relate to?

This is the first time I have had this message appear in 9 and a half years of owning the car. Every time it has appeared, I have only just stopped the car and a couple of seconds later the engine cuts out, and then within a few seconds the traffic flows again, and releasing the footbrake, the message appears and I have to start the car manually. When I plugged my Carista OBD2 device in and read all the fault codes, it ran through I think 27 or 28 controllers and found 4 fault codes, all the same and all to do with the TV Tuner (which is actually working). There were no other codes detected, so I did a reset of the 4 codes and have driven the car a few times now and the "start car manually" message has not appeared and the start / stop has worked flawlessly. Checking for error codes again and none found?

Yes, I did mean to say that it did not accept the code, I will try again tomorrow.

I did try to do the coding today, but I got a message back saying that my vehicle was accepting the code, so maybe I need to get my local Skoda service approved garage to do it for me? Maybe if the system will accept the coding that my time issue of the solar-powered cooling fan might work again. For those that don't know, an option on my model of Superb was a solar panel built into the sunroof to power the cooling fan when the car is parked in the sun to provide a modicum of cooling inside the car on hot days. It stopped working 3 years ago when the alternator belt shredded itself and the RAC had to give me a loan battery to get home again.

Thanks, I'll try that tomorrow if it happens again. It shouldn't be battery issues because it has a brand-new battery on it, installed just 4 months ago and the diagnostic tool shows the battery voltage with engine off as being 12.2V. Tomorrow I will register the battery to the ECU which the diagnostic tool seems to think it has not been done.

A couple of times this week, after coming to a halt in traffic, the engine stops but fails to start again when taking my foot off the brake and a message appears in dot matrix display that says (can't remember exact words), something like Start engine manually. As my car is DSG, this means that I have to move the lever to "P" in order to start again and then move back to "D". This all very off-putting as it is the first time the car done this since I have had the car, purchased in 2013 new, so I have got used to the Start / Stop system being utterly reliable. Any ideas as what is the cause of this?

I'm in agreement, it has to a problem with the clutch, for the engine to increase in revs without an increase in road speed it must be clutch, there is nothing else in the drive train that would allow higher engine speed without the road speed also increasing.

I'm actually noticing that the car has a feeling of enhanced power being delivered to the wheels now, just shows how much energy the alternator was robbing from the engine just to be able to recharge a failing battery. The decline in performance is so slow that you don't notice it, but once that burden is taken, you suddenly become aware of the increased performance as a result of the battery quickly replenishing the power taken out by the starting process.

I've already noticed that my MPG figure is improving due to the stop / start system working more than it has a for a long time when in heavy traffic 👍

Update time on this saga, yesterday morning the car would not start when I was trying to take my wife to work, I have RAC assistance, I decided to call them out and after a couple of hours they arrived and checked the battery and confirmed that it was finally toast after testing it with their high-tech test rig. They jumped the car so that I could get across the city, armed with my 4 year warranty on the battery, to my local GSF auto parts who supplied that battery just 3 years ago. I gave them the RAC test report, but they said that they needed to do their own test to either accept the warranty claim or reject it. The put their tester on the battery and concurred with the RAC, and within a few minutes produced an identical brand-new battery for me, which I fitted and alls well that ends well.

Seat belt was finally fitted this morning, all appears to be good but boy it sure took a time, almost 3 months from the problem first arising to being resolved, one of the downfalls of having a rare model I suppose, no doubt had the car been an SE or even a basic trim level, it would have been far quicker to fix 😞
