I most do town driving so mileage isn't great 25-30mpg on short journeys.

I went to London and back and on a round trip and I managed 50mpg + 😲. I was quite shocked when i checked my short journeys on the trip computer when I got home. It was a mixture of motorway and town driving but didn't expect 50+ mpg from a 190bhp 2.0 engine sitting at 65-70mph on the motorway with AC on auto. 

Thought I'd share some good news for fellow petrol heads of similar engine. 🙂

Anyone else managed to eek out more then 52.3mpg to b exact from their 2.0T TFSI engine 190bhp?

Considering taking one of the current raft of A4 Avant deals for this particular model, at around £270 per month for 5,000 miles pa plus 9 months downpayment. Cannot quite get my head around why these are going so cheap compared to others, both non Audi but also eg 35 TFSI. Is it purely due to the discontinuation of the A4 Avant line making way for the A5 Avant? What's the catch?

Got a link to the deal please?

Thought I'd update here, the mechanic has fixed the issue, replaced the quick acting coupling properly, greased the ends, new coolant and bleed too. Didn't have to replace radiator. All sorted no more leak and temp staying at 90c on dash 😊.

the screwdriver is pointing directly towards where the pipe plugs into the radiator outlet.

Just to confirm, i took some more picture of the clip from the radiator side and this clip can't be undone and replace right, it still has to be the whole radiator?

If you look at the end that's broke off you can see the connector with the little silver circlip the same clip that's on the other end where it plugs into the expansion tank. Plugged into that clip on the radiator end is the radiator outlet that's broken off the radiator. 

It's part of the radiator and cannot be replaced, the pipe is fine but the radiator is buggered! 

I've just looked at mine and the radiator can be removed easily enough.

It could have been knocked at some point and weakened it, or excessive pressure in the cooling system could have caused the radiator to split or it could even be a case of someone breaking it in the past and glued it back on.

Anyway any good garage will be able to replace the radiator and check the cooling system is working properly.

Did you not get a coolant level warning appear on the dash? 

Ahhh right okay this makes sense. Thanks for taking a picture as well, I see what you mean. Both sides have clips but one is from the radiator which is the one that's broken and can only be replaced by replacing the radiator itself. 👍🏽

At least I can speak to my garage with some knowledge now. Thank you once again buddy. Let's see what they say next week. 👍🏽

You can see the outlet still clipped into the pipe. It's broken off the radiator. You could try and glue it but it's not gonna hold for long. The system will be pressurised when hot! 

You may be able to remove the radiator without taking the bumper off but I can't be sure. I'll look at mine later and see.

What do you mean outlet clip?

Thanks, I'll have to get it towed to the garage as it's not fit for driving with no coolant going to radiator! Really don't understand how it could snap like that ugh. 

Just to confirm it will be the radiator / clip itself not just the clip that has to be replaced? I'm just asking more for me to understand the issue but will be getting it towed to a garage for them to diagnose the issue. 

You don't think i could just get the part itself replaced? Managed to find this online

Hi all,

Audi A4 2.0T TFSI B9 2017 facelift - 

Lost coolant few days ago, topped it up and last night heard my fans going crazy and temps showing 130c. 
 

Filled up again and checked engine bay and noticed the leak here. Any thoughts on the parts that may be involved and how to fix it? Is it a wider issue or just the hose needs replacing? 

Is it safe for me to drive this to a garage 20 min drive/15miles ? 

I've attached some photos and a video. 

Thank goodness I have this thread! I felt the brakes doing the clicky bit when pressed firmly and the brake servo error appeared. I turned car off and back on again and it disappeared. The next few days I was out driving and the error came back on. I parked car up and haven't driven it since. Ordered the part off eBay and just fitted the new sensor now. Error has disappeared. Thank you guys, this was a life saver. Hopefully caught it before ABS went to !Removed!!

Audi A4 B9 2.0 TFSI 

I ordered the sensor off eBay £14.99 Brake Booster Pressure Sensor 5Q0906207 5Q0906207A👍🏽

Update: I replaced the battery last week, and while I was doing it I unplugged and cleaned all the seat connectors but the backrest does not heat up.

Not sure if I can be bothered to claim on the warranty / get it fixed because it's not something I need from the car.

You may need to clear fault codes after cleaning the seat connectors and then try again once vehicle is off and then back on?

My A5 has the same fault.

I may get round to resolving this.

Let us know how you get on.

See my last comment bud, try that out and see how you get on, let me know!

HI its probably a dirty/loose connection under the seat, couldn't tell you which one without a diagram, but the easy way around it is leave the car overnight and then unlock it from a distance, get an assistant to open the door and keep the key out of range, this will give the airbag module time to drain down and it won't cause problems as they only work on 4ohms, then take off one plug at at a time and clean with electrical cleaner the connectors often become loose due to the seat moving back and forth when hoovering the car.

 I took my car down to my mechanic this morning as he was replacing my heated wing mirrors as they had failed and I asked him if he could take a look at my driver side heated seat backrest not heating up and he basically cleaned the connections under the drivers seat and plugged them back in, reset the fault code and now I finally have heated backrest again whoop!!!! So happy haha. 

 drivers side back rest wasn't heating up this morning but yet bottom part of seat was heated up nicely?! I tested passenger side and the whole seat works fine only the drivers side back rest that isn't working? 

Any ideas?

Mine is a 2017 A4

From Carista App fault code- 

Central electronics:
65685 - Heated seat backrest; front right - open or short to plus

i expected from diesel to have better mpg in compare with petrol,im  a little disappointing about this engine mpg

I think 50mpg for Diesel doing 70mph isn't too bad tbh. I had a 1.4TFSI Seat Leon and that managed 55mpg+ at 60mph on the motorways but sooooooo slow and smaller haha. 

I saw this option on Carista app to enable lane assist but i'm a bit hesitant myself as i also don't have the correct stalk with lane assist button. Not sure if it's worth the risk when i actually would want it off. Not worth the risk imo. 

I recently purchased a 2.0TFSI 190bhp Auto A4 and i did a 50 mile trip mixture of town and motorway and managed 47mpg at 60-62mph for comparison. Yet to really do some decent mileage as only owned it for a week but i thought it wasn't too bad for a 2.0 petrol.
