Yeah I was trying to avoid having to sell a kidney...

Hi. My wife's 65 plate Fabia mk3 1.4 TDI has had a few problems which I've been fortunate to find help here, so thanks all for your help so far. Latest one is.... We believe there is an issue with one of the 12v power supplies in the ECU. Using VCDS there is a 12v supply that is showing around 3.5v and it is displaying an EML on the dash (I have scanned and it is indeed it is a terminal voltage code) I have sourced an ECU from a breaker (from a donor 1.4 TDI mk3), upon installing this new ECU, this specific power supply is happily at 12v on the new ECU. However, obvisouly the car won't start as the immobiliser (and anything else I can't think of) are not correctly programmed. I've reached out to a few "tuning" businesses and independent garages, but so far no one could clone the old ECU into the donor one. Would anyone know who could tackle this? I am in Oxfordshire. Thank you

Hi So I found some info online pointing at a service bulletin for example: Known Problem : TSB 2039142 - Update to Index L (SW 0023) However, I can't seem to find any info on how to access this TSB? Would anyone have any ideas? thanks

Thanks for the help so far. I scanned the car with VCDS and got the following: Address 03: ABS Brakes (J104) Labels:. 6R0-907-37x-ESP90.clb Part No SW: 6C0 907 379 G HW: 6R0 907 379 BA Component: ESP9.0i H03 0003 Serial number: 08506211150402 Coding: 43F5287D892933C10916106A0057C21491CC9008000BC8F98F00 Shop #: WSC 13765 031 00043 ASAM Dataset: EV_Brake1ESP90iBOSCHPQ26 100018 ROD: EV_Brake1ESP90iBOSCHPQ26_SK26.rod VCID: 33330D50BBB27C729A1-8066 1 Fault Found: 0608 - TPMS Display C1146 F0 [10001001] - Not Available MIL ON - Confirmed - Tested Since Memory Clear Freeze Frame: Fault Priority: 4 Fault Frequency: 2 Reset counter: 253 Mileage: 126909 km Date: 2024.11.24 Time: 10:09:20 I did reset the codes but it came back straightaway Any suggestions would be very welcome Thank you

Hi all I have a problem with my wife's 65 plate Fabia (1.4 TDI) Tyre pressure warning. The other day the warning came up on the motorway. We stopped at the services and checked all pressures low-ish but ok. (2.2 bar all around) We pumped them up to 2.6 all around, reset the system and drove home. Next day, wife drives to work and gets there all fine. She goes to drive home and the warning came on as soon as she started the engine. When she gets home I check the pressures and they are all bang on 2.6bar. Next (cold) morning we reset the system on the car and she drives to work. She goes to drive home and same thing happens (warning comes on as soon as the engine is started) Checked pressures when she got home and bang on 2.6 bar. Any advice would be appreciated. Thank you

So after a few long months the car runs fine. Tanks and all fuel lines cleaned, new hpfp, new injectors, new battery, cambelt, waterpump.... the works! ECU sent out for testing, all good (I've been told) BUT...... we have 2 new fault codes. First one from engine ECU complaining about Terminal 30 voltage - open circuit - this is turning the EML on. Second one from Battery Management Module complaning about no comms to ECU The second one (Battery Module) I have cleared once, it came back again. I cleared again, drove the car for a few miles and it hasn't come back (yet) I have checked all the fuses in cabin and in engine bay and none are blown. Any input would be appreciated. thank you PS: photos from today - clock was wrong but I set it after taking the photos

Hi Kieran Car is still with the garage and they have been working on it. It has all been delayed by parts delivery and a few parts arriving wrong and having to then wait for them to be swapped out. I *should* be getting the car back later this week and I will let you know.

No that I can see/smell. I've pumped the fuel out of the filter into a bottle and it smells like diesel and there is no separation. Bar sending the fuel for some chemical analsysis, I am not sure how to establish that? cheers

@Warrior193 the image below matches the engine in the car. cheeers

right.... the plot thickens.... After quite a bit of discussion about the 3 injectors failing at the same time, the garage went to do some work and taken quite a bit of the fuel system apart and they have told me it is covered in swarf between the fuel pump and the injectors, and then on the line that goes back to the tank, current thought is HPFP wear which has pumped swarf into the system. This would be quite a considerable repair bill as we would be looking at: - 3 injectors - HPFP + cambelt - cleaning the whole system. This kind of explains the whole saga and why when I pumped fuel into a bottle from the filter outlet it was clean, and why the 3 injectors failed at the same time. We've spent quite a bit of money with the garage to diagnose the problem (and would still have to pay them if we scrap the car) so it's looking at quite a big bill (which they will come back to me with a number in the next couple of days) so we have a few options: - get them to do the work - scrap and hope the scrap value somewhat offsets the fuel bill - buy a stop gap car, tow it home and work on it in my weekends to try to get it up and running

I have since spoken to the garage as I had loads of questions, as you can imagine. @nta16 Their diagnostics process involved removing the 3 injectors and testing them on the bench, they could see the trigger coming from the ECU but the injectors would not fire. I believe the CUS engines are new for the mk3 (and a Polo mk5) @Warrior193 I agree, unlikely all 3 failed at the same time, but the garage seems to be convinced that this is the case. @J.R. Thanks for your nice comments. I am somewhat familiar with similar bits of kit (on the electrical and electronics side - not mechanical), but not really with road cars and specially not diesels. I do agree that I should be able to diagnose and fix "simpler" problems. However, I really don't have the time, or the confidence to go much further, allied to the fact that the wife really does need the car back asap. I was very concerned about hydrolocking the engine and I had also read about easi-start damagine the liners as it would affect the lubrication? I do feel a bit had over and that they are using my money to buy kit needed to diagnose the car and taking the ****. When I got the VCDS, I was hoping to find VAG specific DTCs and look at live channels that would point me in the right direction, but after this wasnt really successul, I thought it was better to leave it to the garage as they would have experience with diesels (and the mechanical side of things). in summary, I feel that's quite a lot of money and I am being a bit had over but I really could do with a working car and hopefully this fixes it and it gets us going again. One of our other questions, if this proves to be injector related, is if it could be related to poor quality Fuel. Car usually sees Tesco's finest(cheapest) offering. Whilst with my car (not a Skoda) I tend to use "branded" fuel. cheers

Further update on the matter. Car has been with a garage for a couple of weeks (trustworthy from previous experience). They have condemned the 3 injectors and say they all need replacing at a £1600 bill (which includes the diagnostic labour). I'd be keen to hear your thoughts

I shall await for @ApertureS, comments then!

@Warrior193 thanks for your message. How would I check it? I am getting RPM reading on VCDS from the crankshaft sensor and it seems to be correct (around 400 rpm whilst cranking)?

Hi all First time poster after some help. Wife's car is a 2015 (65 plate) Fabia III 1.4 TDI (CUSB) on around 75k miles. Last weekend she was driving on the motorway and the engine just lost all power, as if someone has turned the iginition off. Dash all ok, no engine/glowplug lights. Everything else working fine. Car cranks healthily but does not start. I drove up there and with a cheap OBD reader there were no fault codes stored. We got it recovered to a garage (independent that we use for our cars) but they haven't got a slot to work on it anytime soon. I have *some* mechanical/electrical/electronics experience but not much, especially not with modern road cars. I have since got the whole VCDS/Delphi kit, and this is where I've got to, after spending a few hours on it this weekend (which included trying to learn VCDS + Delphi!) - Transfer pump works (if you disconnect the fuel pipe from the HPFP and crank over, it pumps fuel well) - I've pumped fuel into a bottle (using VCDS to override the pump) and fuel looks ok, not cloudy, and no separation (ie water) after leaving it sitting for a few hours - This happened at half tank, so over 20 litres (of the same fuel) had gone through the engine (so not a misfuel and unlikely dodgy fuel) - No engine fault stored, so I've unplugged some stuff to see it would flag codes(ie fuel pressure, fuel temp, fuel solenoid) and it does immediately flag a code. There is one sticky code which is related to the Radio Antenna, but I would have thought it is unrelated - Fuel Rail pressure (whilst cranking) is good (300-400 bar), which would rule out transfer pump, HPFP, fuel solenoid - Crankshaft and Camshaft sensors read RPM (oddly enough the same RPM, i would have thought the camshalt would read crank/2) - Cambelt all looks in good condition and changed about 30k miles ago - Checked all the fuses, nothing blown - MAF reads about 3-4g/s whilst cranking - I've tried both keys (thinking transponder...) - Battery takes charge and holds ok (not really new new battery but not in bad shape) - Glow plugs read the correct states on VCDS, plus I don't think I'd be needing glow plugs in this weather (25+ deg C in the UK at the moment) - Tried a bit of EZ start on the intake and it does try to start, but I dont want to overdo it and cause any damage I might have forgotten to list some stuff I've tried... definetly out of my depth by now! next steps would be to check all the relays (but I can't find a relay box diagram, plus it looks proper well stashed behind the dash so I would have thought some major disassembly would be required?) Any advice or pointers in the right direction would be much appreciated. Thanks in advance Patrick

Hi all Sorry to necropost, but @Olimk1 did you find a solution for your issue? @Breezy_Pete I'm struggling to find info about the relays online. Do you know where I can find he diagram with the relay functions? And what's the best way to get to them? I can feel them with my hand, but I guess if have to take some of dash apart to get to them? Thanks
