Oil Leak Post PCV Valve Replacement

oil leak

July 14, 20196 yr

Hi Guys Looking for some help regarding oil leak spray on my 2010 Audi A5 1.8TFSI Engine Type CABD post PCV Valve replacement.The car was originally giving error codes P227900 Intake air system leak and P017100 Fuel Trim System too lean which looking at other forums can be due to PCV valve issues. On replacement I noticed some oil in PCV but as soon as I replaced car was noticeably smoother not hunting at all. On first drive the car had spray of oil near air filter box and line leading to it. When I removed line I noticed some oil in this and suspect it may be coming from this location . The question I have is why replacing PCV valve would cause this and is there any other oil leak points this may have generated. Ive attached Pictures. Any help would be much appreciated.

Regards,

Jackie

C5 RS6 034 strut top mount

petec5 · 9 hours ago9 hr

Hello all After a year of owning my first RS6 c5. It seems I'm in need of new strut top mounts. Do any of you have experience of the 034 rubber mounts? I've seen they are solid vs original ones that have bearings. How much of a difference does this make. And on a side note has anyone used RB Racing brake disc. What's your thoughts? Any help will be much appreciated Pete

Help with some issues

Kian · May 27May 27

Hello everyone, Wondering if anyone can help me. A few weeks ago my EPC light came on and immediately went into limp mode and started jumping when driving at 5mph. After a few hours I came back to the car and it was fine so I drove it to my storage unit. I came back the next day and when starting it the EPC light and EML light were illuminated and the idle was quite rough. I came back to it about a week ago and all the doors were locked, the key isn't unlocking it and the barrel of the central

ZeroX · Saturday at 10:46 AM5 days

Hi, following on from my previous thread, I have seen another car that I was interested in: https://www.evanshalshaw.com/search/details/used/audi/a5/automatic-petrol-white-coupe/06ce9494-f94d-f111-8fdd-000d3a874790/ When I enquired with the dealer, they said there is only one stamp in the book from February of this year, and no history at all in the Audi database. So there is only evidence of 1 service in almost 10 years. I am starting to get a bit !Removed! off with this actually, and it's real

Wing mirrors don't fold out when unlocking the car.

Wing mirrors don't fold out when unlocking the car.

john260164 · 3 hours ago3 hr

Hi. My partner's recently bought Q2 has an odd and not very welcome feature. The wing mirrors fold on locking the car with the key pilp, but don't unfold when the car is unlocked with the plip. They only do so when the key goes in the ignition. In some circumstances this can lead to doubt about whether the doors are locked or not whereas before it was obvious as the plip alone folded and unfolded the wing mirrors (as is does with my similarly new A3). The garage says it can't be changed but does

Hi all I have had my A3 since September 2025 and I haven't yet been able to figure how to park it in my garage with the brakes off. It's an auto and I have read lots of stuff but I cannot figure it out. I may be stupid but there you go any helpful advice will be appreciated. JB

Bobs dad · 6 hours ago6 hr

I have a new A3 Black Edition auto. Within four weeks of delivery the engine cut out whilst driving, the drivetrain under positive power. The car rolled to a complete halt, the retardation entirely commensurate with the wheels driving a dead engine - it did not freewheel. The instrument panel remained powered and displayed no warning lights or fault messages. I shut the car down and after a pause restarted. Since then it has operated normally. The Distributor has found no data supporting t

Andy baggy · May 21May 21

Recently while driving my EPC light came on . Followed by my engine management light. Unfortunately I was on the motorway so put car into sports mode in the auto box to keep the revs high so I could get home the 49 miles. Been to the garage this morning no lights on my dash they diagnosed 2 coil packs going down. They are going to replace all 4 spark plugs and coil packs next week. They also said that I may now need a new catalytic converter. Has anyone had any issues with this sort of proble

A% front suspension groan

IainH · 2 hours ago2 hr

Last summer while in the heat of southern France, my A5 (Dec-2017, 40,000 mile) developed a front suspension creak. It was always at low speed and particularly when turning left. The car was completely checked on my return, 'shaked, rattled and rolled', but steadfastly refused to creak once, however, everything was checked, levered, put in a shaking plate, and no creaks or movement in joints found, and so while noisy, the car was declared 'good' (safe). The sound is very like the creak heard her

Lewbyleww · 9 hours ago9 hr

Hi all does anyone have any idea on what this distinct tapping noise could be? had the rocker arms, lifters, injectors and all cam followers replaced and is still present. Noise is at idle and speeds up with acceleration and can hear it inside doesn't affect performance. Been advised by three separate mechanics its not bottom end so at my wits end really, any thoughts appreciated. Thanks a7bcf128-5947-4002-afba-29c811dd5d88 (1).mp4

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

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

S-Line suspension change

lbr1978 · May 17May 17

Hi all Looking for some advice on changing out the rather firm and jittery S-line suspension on my 2024 A3 8Y (black edition) to something more comfortable and softer (possibly akin to standard SE suspension or equivalent). Any suggestions on what I should be considering and looking at for daily driving only please? I’ve heard Bilstein (B4s ?) and maybe the eibach pro springs would help make things more comfortable? thoughts and suggestions much appreciated. Any real world experience of changing
