Just back from garage, really impressed with them (E M Hughes. Oswestry) Basically they have cleared the code and it never reappeared. Fuel pressure lower than it should be but because it hasn’t lit an alarm on screen it’s within tolerance. Suggested driving it and if warning comes on or car cuts out or any other niggles then will have to check fuel flows to determine where the actual problem is. Could be fuel pump, pressure sensor or even a weeping injector. All that cost £24, unreal. He did suggest changing to E5 fuel or additives.

Steve, Yes battery was coded to car and all is well at present, no EPC or random messages. Will know tomorrow if “fuel” fault is still there.

Cliff, Thanks, got it booked in with independent that advertises “ dealer level diagnostic”. We’ll see what they find tomorrow. Fingers crossed !!

Cliffcoggin, Thanks for the reply, bit confused though, what is the difference between an Audi tech and a VAG tech ?

Finally had a new battery fitted, the car was throwing up all sorts of errors on the dash, ‘ put in P or N to start’ when it already was and clicking on the key several times before actually turning over. Seems to be sorted apart from a ‘fuel pressure fault’ which only appears in a diagnostic and keeps returning after being cleared. Had it booked in at an Audi dealer but in a nutshell they let me down with no apology so got back in car and drove home, 60 mile round trip wasted. Car drives fine ( start/stop works) . Local mechanic is unable to narrow down the fault and it was him who suggested Audi. Any ideas what to do now ? Thanks in advance

Gareth Thanks for your time and advice, very helpful. When it gets worse I will arrange a new battery. Mike

Hi Gareth thanks for the fast reply, appreciate it. Yes I put a multimeter on the battery and got 12.5 v while engine off and assumed all ok. I know these things happen but would you expect a 3 yr old battery on a 27k miles car to start to fail already ? When you say “coded” do you mean Audi have to do it ? Mike

Just got the car back after 1st mot, after doing a diagnostic I was told there was only 1 fault relating to fuel pressure which was cleared. Driving back the stop/start is still not working ? Started the car yesterday and the EPC light stayed on with a stop/start warning. Turned engine off, restart and all cleared again. Not too bothered about stop/start not working as I tend to turn it off in town but it’s the Epc that’s a concern. Had to drive it with the warning on recently because I couldn’t stop, it ran ok, not in limp mode or anything. Help !

Hi Steve, thanks for the reply. Will get it sorted and forward any findings.

I have a 20 plate 35tfsi Black Edition sline Q2. The stop/start never works, it always shows a line thru the symbol on the dash but now I’m getting occasional EPC warning symbol shortly after starting the engine and driving off. If I stop and restart the EPC clears but stop/start is still not working. I have checked the battery and getting 12.5v without engine running. Any ideas before I shower it in money please ?

New to this forum but need advice. Recently bought an A1 , 2015, 1.4 s line with a 7 speed s tronic box. The car is nearing 40k and was concerned about the gearbox service. I checked with a local Audi dealer and was told it needs NO servicing. This can't be correct surely ? The car was purchased from a different Audi dealer and when I asked about the gearbox service he told me it would have been done, if it needed doing, before the car was collected. Help please !!!
