Thanks everyone for the help with this. As promised these are some better photos of how it fits: You first have hook the two "prongs" or lugs on the front of the part behind the two "rails" cast into the bumper as can be seen above. The part then clips round the back of the fog light bracket as shown And this is how it looks when installed on the car. I've no idea what its function is really, all I can't think is it's just to help with directing air into the inter-cooler? Anyway thanks again for all the help!

I'll get some better ones in the morning when it's stopped raining Cheers

Is this how you mean?

Hi is that image any help? Looking at in person it doesn't look like anything has cracked off

That's what I thought from looking at some drawings online but they aren't very clear as to how it mounts

The part in the attached images had the code 6Y0 853 666 G and is off a 2006 Fabia. When I took the bumper off this part fell out and I can't for the life of me work out where it fits back to. If anyone has any information that would be much appreciated! Thanks

Cheers for all the feedback, very helpful as always! The valve was cleaned at about 100K and it was pretty horrific. The car's also been running +200 mbar more boost recently and the leak has got slightly worse which makes sense so I think I'll probably end up fitting catch can to stop oil getting into the intake in the first place.

I've attached an image of the EGR on my car (just realised how dirty the engine cover is) and as you can see there's a fresh oil leak coming from it. I know oil in the intake is normal but the fact there seems to be enough to find its way out the top the EGR is worrying me. I've checked the oil regularly and there's been no discernible loss. I've also tested the EGR valve with a vacuum pump and it holds a vacuum and I can hear it opening and closing so it's fine in that respect. The car also runs totally fine and there's been no power loss to speak of. Is this nothing to worry about and the seals being worn around the EGR valve or is it something more sinister (rings?) Cheers

Yeah the turbo is quite hard to access on the 1.4 so my measurement was just done with MIN/MAX feature and just waving the thermometer about in the general area.

KW1281 was designed by VW and it's true the car does support it. However the car does definitely support ISO9141 (Tested working with my own ELM327) for functionality with "Generic" test devices such as the ELM327. Possible you've got a bad dongle mate?

Is the ignition on/engine started? Simplest thing first EDIT: Do you have a aftermarket or replacement radio fitted? If you do that's probably the issue! You're right the car does use the ISO9141 protocol for Diagnostic over the K-line bus. That bus is shared with the radio to allow certain OEM features to work. Aftermarkets radios don't use this functionality and some connect the K-line either to Ground or to +12V which totally stops any diagnostics (Including ELM327) from working. Link to Ross-Techs article about the issue

VCDS logging on a Octavia VRS Diesel shows EGT's from about 400C to 600C depending on conditions, so very hot! And the heat gun idea on the Fabia turbo gives about 250C on the housing and 200C on the pipe just before the flexi-joint in the exhaust. (That's after a few medium to hard accelerations). EGR's are present and using standard mapping on both cars and it'll be staying that way thanks to all the input on here and the fact the valve shuts anyway as soon as you go near the throttle.

Good work, glad you manage to work it out! I'm still looking into adding "staging" by writing some custom code into the ECU. However, progress has been quite slow because a lot of threads relating to EDC15 reverse engineering are very old and a lot of the information needed it spread out across many forums so it's a bit tedious. But from what I've managed to work out so far it looks like it should be possible!

Thanks for all the replies everyone, very useful as always! There was a thread I was reading on a ECU tuning forum about EGR delete and dynamic EGR (EGR control with coolant temperature) and a few people were mentioning that as the EGR lowers combustions temperatures and that disabling it would result in higher EGT's and possible turbo damage. But after reading your replies and doing my own research it seems the difference it makes would be negligible. Cheers

Cheers for the info. And can someone confirm that this car does not have a EGT sensor from the factory (I know many new engines do but I'm pretty sure the MK1 doesn't?). So realistically there wouldn't be a way of measuring the approx. bearing temperature or exhaust housing temperature by making a bracket to mount a sensor to the turbo itself? Cheers

I have a Fabia 1.4 TDI (BNM engine) and I was wondering if there was any way of measuring the temperature of the Turbo charger? I know I could fit an EGT sensor but this would require modification to the exhaust so would it be possible to fit something like a K-Type thermocouple to the housing and get a temperature that way? And if so what would be a safe / expected temperature? I'd just like the point out I know its a totally pointless task on this engine but I'm just curious if it could be done.

Guessing you've used the stock harness between the cluster the BCM and connected the Kline of the BCM to your tool?

Yeah definitely. I'm more into EDC15's and recovering them and I've just started to get into reverse engineering them. Only thing I'd say about Nefmoto is some of the information is a bit all over the place but you can find it with a bit of searching.

@hutchysrs50 I can't find the launch control thread right now and it's only ECU connections so you'd need an account to view it anyway. But this is a thread by the same person on Nefmoto that shows how to disable checksum which you need to do to add launch control/staging anyway. You could probably work out how to correct the checksum for the IROM but it's much easier to just bypass the code that checks it I'll see if I can find the other thread tomorrow if I remember.

Will do. Yeah the thread's adding rolling launch control and getting the tacho to show boost but's got load of info about how ECU and dash talk and how to disable checksum verification etc. All very useful

I'll have a look into adding staging over the next few weeks then. It should be possible by writing a bit of assembly in the ECU start up procedure that just maxes the dials and then drops them again. One of the guys over at Nefmoto / ECU connections already found registers that control the Tacho so it shouldn't be that hard to find how to control the speedo too. I'll do a thread on here if I work it out but it wouldn't exactly be a DIY mod lol

No worries!! I'd offer my Fabia for testing but its my daily and I can't really risk bricking my dash Are you aiming to just get the illumination or the "staging" feature as well? Because I could probably get staging to work even if it wasn't supported but it'd involve flashing the ECU rather the dash. Keep up the Good Work!

Not sure if I can be of any help here but I have the EEPROM dump from my dash somewhere (2006 non VRS)
