Mk5 General Area / VW MK5 2009 model with a BWA engine petrol and its automatic

« Last post by okechokech on Yesterday at 02:15:37 pm »

i have a vw 2009 model it has a BWA engine which is a 2 litre petrol and the vehicle its automatic.  its VIN is wvwzzz1kz9m307742.  the car has a problem of fan the fan isnt kicking in in time and also its very slow kicking even when it kicks in very slow power and then stops. kicks in again then stops. am suspecting the fuses are rearranged badly and i have tried to go everywhere i cant find the exact fuse diagram i cant find it i need your help if someone can have the diagram of the fuses how they should be. i think my mech rearranged them and there is trouble now because its over heating. one other problem, when you turn it on after a few minutes without stepping on the brakes you can see the green light for brakes blinking and you can hear a sound in the gear box as if something is happening . the abs light is on when i insert the machine to look at the codes it says abs isnt communicating . so i dont know whether the pump might be faulty . so the car speeddometer when the abs is on doesnt calibrate what speed am in but it comes and goes when its not there the car speedometer is fine. please assist me with the fuse box diagram i have attached a photo of my fuse box[/img]

How to Guides / Troubleshooting / Interesting p0299 issue

« Last post by MKVASMR on July 04, 2025, 09:42:35 pm »

Hi guys!
So I have noticed that the car felt slower the last couple of months. Today I read the codes and saw the P0299 under boost code that I have been fighting in the past. I thought it was probably a DV or a leaky intercooler hose since I've changed the turbo with an OEM one from VW. So installed a gfb diverter valve and whoops same code. Around 300mbar lower than the specified to be exact. So I decided to do a smoke test, connecting the smoke machine to the intake and saw 0 smoke. (Untill I opened the oil filler cap!) It smoked like a chimney! So maybe I have a faulty PCV? Did the usual check with the car on idle and opened the cap. I could feel some vacuum but the way the engine was running haven't changed much. Luckily I had a spare one and swapped it out quickly. Started the car, did a small test and the car was boosting around 100mbar more according to the logs. That still however didn't cure the fault code. (Which I've obviously cleared before.) Now I'm thinking if maybe I have the issue with the rear pcv since I have never changed it previously. I'm not sure but I don't think I should see any smoke coming from the oil cap when I do a smoke test.
Was wondering if someone has ever troubleshooted this kind of thing.

Open VCDS and look for misfires. See which cylinders are doing it and how often. Measuring Blocks 14-15-16

will take a look there, but shouldnt it give misfire code if it counting them?

Sounds like the oil pressure control rings on the cam actuator to me. Does it sound better when the revs are raised up from idle?

the 3 oil rings i change 1.5 years ago same time as the timing chain. the issue is on only idle just 1% gas will make it run perfect, the cam adjustment and phase position are always good when looking at live data. and if it was the vvt it would throw a code fast when i was going 160kmh cruise for 90km, but zero fault codes.

hi, i have got some problem with my golf 5 gti 2008, that started to have issues a week ago, first fault code that came up was P2187 (system too lean at idle,bank 1) and after a swapped spark plugs while i wait for my new pcv part it change to p2279 (intake air system leak) and now with the new pcv that a testing by blowing and sucking it doesnt leak like my old one did, but it still running rough only at idle as soon as i give gas it goes away and today i cruised at 160kmh for 90km without issues. and my injector only ran 5000km since service with good numbers before and after the service on them. anyone have had problem with coils that doesnt work right only at idle and doesnt throw any fault codes?

Oh yah, I forgot to mention. The scirocco clocks need specific ABS pumps. If you have an older one or one that's not compatible, you'll need to change that too.

Have a read through this post https://www.mk5golfgti.co.uk/forum/index.php/topic,112537.0.html

Mk5 ABS pumps that work with the scirocco cluster:

1K0 907 379 Q
1K0 907 379 AA
1K0 907 379 AC

I got them from here: https://www.aliexpress.com/item/1005006821485910.html?spm=a2g0o.order_list.order_list_main.5.32b31802RaDno8

Used this post as a guide for cleaning the paddle contact points: https://www.vwvortex.com/threads/dsg-paddle-shifters-working-intermittently-implausible-signal-in-vcds-fix-inside.6915231/.

You have to clean those 3 solder points. It will shift perfectly again after and the vcds error on the paddle will be gone.

Thanks friend, much appreciated!
