1 hour ago1 hr

I just changed battery on my a4.

I have put in a bosch battery without BEM Code.

I programmed it with mucar tester, where I just changed the 3 last numbers.

When i try to change the clock in the dash, a lot of fault coming i the dash, when the computer have shown all the failures, they Are gone, and Will first Come back when i push the SET button Again....

It comes with a faulure l2 4/4 at the trip spot. See picture

I have tried to remove the minus for 10 minutter, and delete the failures with odb. But the failure keeps coming......

What to do?

2019 Audi A4 NMI Updates

shed13C · 24 minutes ago24 min

Hi Folks, I have a 2019 Audi A4 B9 with the following NMI software: MHS2_ER_AU_P2035 0235 Navigation database V03959802LD 0038 ECE 2019 Media driver DEV_MCM_AU_ER_G21_045P… Could someone tell me if there is a later update for my vehicle? Not too worried about the maps as I use Google Maps. If so, where is the best place to get the update from? Audi dealer? NMIUPDATES.COM? Would appreciate any advice in this area. Thank you for your help. Kind regards Paddy UK

2012 a3 2.0 tdi sportback starting issues

Robwebb1974 · 1 hour ago1 hr

Hi all, Hope everyone is well.. i have had a problem over the past week with my a3 2.0 tdi sportback. To cut a long story short, drove out to bath for an appointment, had the appointment and got back into the car to notice it wouldnt start first time. After several attempts and long cranks it started but seemed to be running lumpy on idle. Any suggestions please to what this could be?? Mileage is 94000. Many thanks.

EdwardT · May 19May 19

Hello, I am hoping if anyone would be able to help explain what may be my issue I have a 2014 Audi A3 1.6 TDI and recently iv been hearing a ticking noise coming from under the dash when I start my car which stops after about 30 seconds and only comes back on when the air recycler button is pressed iv removed the glove box and can see the ticking happens when what looks like the air condition flap opens iv attached a video of what’s happening. Any help would be greatly appreciated.IMG_1775.mov

Audi A4 B8.5 2.0 TDI quattro S tronic – gear hunting

jayformhu · 9 hours ago9 hr

Hi everyone, I have a 2013 Audi A4 B8.5 Avant 2.0 TDI 177PS quattro with the 7-speed S tronic gearbox. I would like to ask for some opinions from people who have experience with this drivetrain. The main thing I notice is that on A-road/main road driving, especially around 55–70 mph (90–110 km/h), the gearbox sometimes seems to hunt between 6th and 7th gear. It mostly happens with small throttle changes, slight inclines, or when I try to maintain a steady speed around 60–65 mph (roughly 100 km/h

Gearbox service

Pete A · Sunday at 11:23 AM3 days

Good day all, I have a 2.0 TFSI with the ZF 8 speed auto ‘box which I intend to get serviced within the next couple of months. Is this just an oil and sump/filter change or is there mechatronic seal (for the wiring) on these? I’m going to get the oil changed in both diffs and the transfer ‘box, is there anything else within the drive train that needs looking at while it’s on the ramp? Mileage is 65,000 miles.

Clutch and flywheel upgrade options

thecapriciousboss · yesterday at 12:25 PM1 day

Hey. First time posting here. Looking for manual B8 S4 owners clutch and flywheel upgrade recommendations. About to drop a painful amount on a LUK clutch and flywheel kit, running 430 lbft. has anyone had any good experiences with upgraded aftermarket clutches/flywheel upgrades in the U.K.? very little about what's available in the UK online as I know manual S4's are pretty rare. Thanks in advance.

So I stepped up got a new motor from Power Engines it came all crated up they were super helpful pleased with them. My mechanic moved all the bits and reattached them to the new engine from the old.

New here and want to acknowledge the new members advise of post and run...I'm here and very grateful for the advice, and certainly not looking to splash and dash.

Titanium · Saturday at 12:12 PM4 days

Although not required as yet, I'm thinking /looking ahead and wondering about servicing costs. Like all Audi dealers/dealerships it's best I guess to have your car serviced by Audi but I'm sure the price/s will not be as cheap as independents? (Yes they would have to use genuine parts). Does this forum show recommended companies i.e good garages that will be cheaper but carry out as good work as Audi. I look forward to guidance. Thank you.

A6 c5 allroad seats

matty_s6 · May 27May 27

Due to turning the car into a track car, the seats and door cards are no longer needed. They are green and grey with wooden look trim. They need cleaning up and the rear seat is damaged at the top plastic part but it still locks in place. £200 ono with the wooden look trim. Collection only though from north west, near Preston. I also have other trim pieces from the c5 saloon that are now out of the car.
