Hey @pab567 - did you get anywhere with 0480 for the MIB2.5 Amundsen units. I think another member was going to try and contact you with it...?

I'd try ticking BCM (09) > byte 3 > bit 5 (Comfort Operation via Remote Control active). If that doesn't work, maybe untick BCM (09) > byte 4 > bit 4 (Power Windows/Sunroof disabled after door Opening). There's also adaption channel 06 in the BCM which looks to be "comfort remote control" which might need turning on.

Get the workshop manual and wiring diagrams from the link I posted above...? That'll show both where the speaker wires are connected and how to remove any trim/parts to access them, simples.

A good starting point would be to get it scanned with VCDS or similar for fault codes

Then my only advice would be to: - buy 5l of G12evo coolant - top-up the coolant before each journey with G12evo (not water) - try and stick to short journey's - check the oil regularly for any signs of coolant mixing Not much more you can do I'm afraid... I've had to do it for the last two weeks on my car and will continue for the next few weeks to confirm the repair as good.

Pretty sure the EA211 is the 1.5l petrol

Both Looking at Seat SSP 161 for the EA211 and EA288 engines, there is the main coolant pump driven by the timing chain and a secondary electric one for the turbo/intercooler.

Given the amount you're topping up, if coolant is getting into the oil, I'd expect a white mayonnaise like substance to be visible on the dipstick and oil filler cap. If the oil still looks like oil, it's much more likely to be the common coolant pump or regulator housing issues and it's just a coolant leak. Have you got the car booked in for investigation and repair?

Where are you adding the water? If you're adding water into the coolant expansion bottle and the coolant level keeps dropping to the point that the low coolant light is coming on, this is not normal and highly suggestive of a coolant leak... Or am I missing something obvious here...?

It's a MIB2.5 Amundsen headunit and screen What does VCDS or similar say? Can it communicate with the headunit? Still, this isn't a MK4 Octavia issue so I'll ask an admin to move the thread

If it's reconditioned I'd defiantly contact the supplier. Depending on why it was sent for reconditioning it feels like: - this is the original fault with it and it's not been repaired properly - it had a different issue and it's just chance that it's got a second one Either way, it's seemingly faulty so hopefully can be exchanged for a working one. I imagine it's a good chunk of work to replace it again though

At a guess, it doesn't have a 4th temperature sensor hence the nonsense reading On my old MK2 Octavia, it had 4 exhaust temperature readings but number 2 was always 0'C... What's the fault code you've got?

A quick google suggests most people who get B200ff0 and B2000f1 then replace the rack... Given you've recently bought it and it had a new rack fitted just prior to that, I'd suggest contacting the garage who did that work as hopefully it'll still be in warranty. At least assuming those are the only two codes. I can't see how removing a door would cause a steering rack issue so I'd probably not mention that

Do you mean you've had to top up the coolant expansion tank for the 5th time? In which case yes, you likely have a coolant leak... - you should be using G12evo to top up rather than water - I'd suggest topping up before each drive, hopefully your drives are short enough so you don't need to top-up mid drive to avoid dealing with a hot/pressurised system - if it isn't already, get it booked in for investigation A coolant leak shouldn't cause an issue unless it gets low enough whilst driving to cause overheating. The steps above should minimise that risk but won't remove it completely. I've had a coolant leak fixed under warranty today, initially it was a pretty slow leak but this week the coolant would visibly drop after a 30-40 mile drive. There are a couple of common coolant leaks which have TPI 2049121/3 assigned to them: Customer statement: • Warning light on instrument panel is on: Coolant low level. • Coolant level is at the minimum mark or below. • Customer had to refill coolant already several times. • Traces of coolant are on cooling system parts or under the vehicle. Findings of the service centre: • The statement of the customer can be reproduced Production change • Optimizing filling process of coolant in CW 12/2015. • Measure to ensure tightness of coolant regulator housing, introduced in CW 27/2019. • Measure to ensure tightness of coolant pump, introduced in CW 23/2020. Checking coolant parameters and cooling system tightness: • Checking frost resistance of the coolant according to instructions in Elsa ⇒ Maintenance – Detailed instructions. • Checking cooling system for tightness according to instructions in Elsa ⇒ Workshop Manual. • Checking cooling system visually for possible leakages:

You shouldn't be able to damage anything by doing an autoscan or adpmap. They are designed to show exactly how the car is currently configured rather than changing anything. I always do them before making any changes so I always know the starting point Once we can see how the car is configured, it might be possible to suggest changes to get the remote close working

Quick FYI thread as I didn't find much when I googled for this fault code I had pop up last week: Address 44: Steering Assist (J500) Labels:| 5Q0-909-144.clb Part No SW: 3Q0 909 144 L HW: 3Q0 909 144 L Component: EPS_MQB_ZFLS 507 5081 ASAM Dataset: EV_SteerAssisMQB 015157 ROD: EV_SteerAssisMQB_015.rod 1 Fault Found: 24320 - Steering C10AC 07 [009] - Mechanical Failure [Belastungszähler hat 99% überschritten Belastungszähler hat 100% erreicht] Despite the rather worrying statement that there is a 'mechanical failure', it turns out at least in some cases, it can be resolved via a simple software update. TPI: 2056240/2 Customer statement: - Power assisted steering efficiency decreased. - Red power steering warning light is on in the instrument panel.

Hopefully this helps someone else with a similar issue in the future, other brands may have a different TPI number

Erm, not quite... To autoscan: - start VCDS - click 'Auto-Scan' - click 'Start' - click 'Save' - click 'OK' To adpmap: - start VCDS - click 'Applications' - click 'Controller Channels Map' - enter 09 for address - select 'Adaptions' and 'CSV file' - click 'Go' You should now have two files in C:\Ross-Tech\VCDS\Logs: - Log-VIN-Xkm-Xmi.txt - adpmap-09-1K0-937-087-D_VIN-X.CSV Where the VIN is your vin and the X's are some number, please attach them to your next post

This is my take, feel free to correct any mistakes or misunderstandings I've made I couldn't find anything Europe EA888 Gen 3b specific but I did find "eSelf-Study Program 920243" for NAR EA888 Gen3 engines which is where the below pictures etc are from. In regards to the "oil circuit", ignoring the usual pressure valves, the only obvious change in oil distribution I can see is for piston cooling using 18 and 19: Which are activated as per this schema suggesting it's only for fuel economy rather than decreased warm-up time: The coolant circuit is a completely different beast and that definitely changes flow paths depending on temperature. There are too many modes to explain in detail but as @flybynite mentioned, it does use the "oil cooler in reverse" to warm up the oil: This doesn't mean reversing the oil or coolant flow as @J.R. understood it. Rather that the "oil cooler" heat exchange direction is reversed to normal so it's being used as an "oil heater". The fluid flow direction through the "oil cooler" haven't actually changed, just the function

I did a quick log of my vRS 245 temps this morning: - ambient was around 12-13'C - it only idled for a few seconds before setting off - first four minutes were through town at 20-30mph - after that is was 50-60mph with a few roundabouts/villages - super relaxed journey given traffic I do have a coolant leak (hopefully fixed today!) so the coolant temps might be slightly off but still, it warms up quite quickly

As @Wino posted, the MOT is a relatively basic set of safety checks. Passing the MOT doesn't mean a car is road worthy or meets all requirements to be on the road The headlight beam pattern/intensity will mostly depend on the projector design in a car with xenon's. The outer lens will have some effect depending on it's shape but it's probably quite small. If you can find out the manufacturer/model of the xenon projector you have, it might be possible to find a datasheet for it, at a guess it'll be a Hella unit? VAG use a variety of different xenon projectors so there will be a difference between car models

Can you post an autoscan from VCDS and an adpmap from 09 please? That should help clear things up

At a guess, it'll be a broken or damaged wiring loom. Take a look at this guide:

Maybe try some other apps too? If it's streaming then it might be using a low quality file until it's had time to download a better one.

It scares me the way the Chinese cameras seem to code themselves in and seemingly even mess with the diag comm's from 5F. Sure, the OEM cameras are more expensive but they avoid these issues I don't think I have much to add I'm afraid @Vahids - assuming you've got a scan and adpmaps from before you tested it, my only suggestion would be restoring everything then connecting it. Might be worth contacting the seller too. Not sure if you know anyone with a HEX-V2 or HEX-NET to find out more detail for some of those errors?

The car probably hit a soot threshold which cause the warning light to show, basically asking you for help to regen. During that mile, It may have gotten the DPF hot enough to start burning off the soot and once it dropped below the threshold, the light extinguished It's just a theory as unless the car now has a fault code stored, it's impossible to tell.
