Head gasket?

Followers

3 hours ago3 hr

My coolant expansion bottle keeps emptying after about 6/7 miles, I suspected a leaky bottle cos I'd had that problem before but I changed it and it's still happening.

Now I'm looking at the oil and it's not good, can someone confirm head gasket failure? Or another explanation for what's happening?

Cheers

I should also explain the coolant remains clear, no evidence of oil. And the temp gauge never moves...

It might be a blown head gasket, it might be a cracked head, but the most likely cause is a defective EGR cooler.

Alternator failure related to mild hybrid system?

PocketsAintEmptyCuh · October 16, 20232 yr

I've been seeing more and more posts across FB and multiple forums about people having the alternator failure related to the 48v mild hybrid system and wanted to see if anyone has had this issue and how their experience has been. I know in USA they have announced a TSB with an extended warranty for 7 years but I am trying to get more info from Audi UK but not getting anywhere. Has anyone had this issue and if so has Audi fixed it (if out of warranty)? It seems to be tha

Battery replacement

LucyB · 5 hours ago5 hr

Hello All - My battery has died and I'm all set to replace it myself. We jumpstarted the car last week and despite it initially sending me a lot of mad messages about nothing working, once I got it going and drove a mile, it was all fine. 2 days later, battery flat again. Mu question is, if I disconnect the old battery and replace it, will all my computer settings be lost?

S3 Parking Sensors

Hi. I drive an S3 2021 Hatch Sportback. My car came from new with Rear parking sensors that Beep - But no Front Parking Sensors. I have been looking around for someone to fit Front parking sensors and a Rear Reversing Camera to my S3. One company called AIC (Advanced in car Technologies) which are based in Poole around Dorset looks good, however they are over 500 Miles from where I live. AIC say they use Genuine Audi Parts and can fit them to my car (8Y 2021) and can fit them and set my car up a

Does anyone know what this high pitched noise is?

redaudi20 · December 11, 2025Dec 11

IMG_2335.MOV Hi there, My A1 1.6 TDI Sport 2017 makes this high pitched noise which sounds like it’s coming from the right rear side. It more tends to happen when the weather is cold. It starts when the car has been going for a couple miles and stops as soon as you turn the engine off. I have attached a video of the noise. Does anyone know what this could be? Thanks IMG_2335.MOV

1994 Audi 100 Quattro 2.8E engine cuts out in high heat

TomMelluish · May 30May 30

Hi everyone, I have a 1994 2.8E Audi 100 Quattro saloon with ~130k miles on the clock. It's developed a problem with the engine cutting out if driven above ~65mph on days warmer than 27 Celsius. Neither the garage or main dealer have been able to find any fault. One mechanic speculated that the fuel pump might be at fault, but the problem has persisted after replacing it. Has anyone experienced this with a similar model? Thanks! Tom

Hi there - i checked through all the pages related to A5 but didn't see anything on this topic on issues with the one-touch open/close function. I have an Audi A5 Cab B9/F5 40 TFSI S line (pre-facelift) and on the cabriolets, you have 4 switches, one for each window, plus a 5th master which does all the windows at the same time. Each switch has the one-touch operation. The rear window switches and the 5th master switch work up/down with one touch no problems. Problem I have: The front window
