Mk5 General Area / Re: Help with intake leak code

« Last post by mjmallia on Yesterday at 08:09:55 am »

Sounds like PCV to me as pulling the dip stick out would make the car almost stall and hate that it was even turned on.

Was it an original PCV as I once used an aftermarket one that failed within a year, put an original on and its been fine for much much longer since.

Mk5 General Area / Re: Help with intake leak code

Update:

Took it to the garage for a smoke test and they found that a screw was missing from the MAF sensor (should really have spotted this myself!) and a blanking cap was missing from the vacuum line. This was sorted and a second smoke test showed no leaks however 2 days later the code is back along with others.






Does anyone have any ideas of what I could do next to check what is causing this? I’m going to take it back to the garage to get their opinion but don’t want to start throwing money replacing DV, PCV, MAF sensor etc if there is a way of narrowing it down.

I have obdeleven if that helps with any diagnosis.

Cheers

Big test this morning as I had not driven the car for two days and it was -1C to add some icing on the cake for a proper cold start.

She started within a split second........has to be the fastest cold cold start in the seven years I have had the car, as usually get several cranks before life, or had to prime the car twice before turning the key.

Very happy, but have ordered the version J pump controller that came off the same car as the pump........I will update!

Nope. The only issue I’ve had is the camera wires snapped due to a design flaw the first time. The second one has been going strong for over ten years.

I had to replace my pressure sensor this year because it was leaking. To find the leak I had a mobile A/C specialist come round and use a detector to find the leak. He had a wand and it beeped where it picked up refrigerant gas.

If it is the pressure sensor it's not the worst job but access isn't amazing and a crows foot spanner is needed

Could be multiple points of leak, but the pressure sensor failing is common.  Number 18 on diagram below. Its usually the o-ring (number 47) that perishes. Easy replacement but tricky to access with a spanner.

Mk5 General Area / Ac losing refrigrant over a period of four days

I am experiencing ongoing issues with the ac system in my MK5 GTI. The system was regassed once, but the refrigerant lasted only four days. A second regas was performed, this time with the inclusion of dye to detect potential leaks, yet the refrigerant again lasted only four days. Despite these attempts, the technicians have been unable to locate any leaks. Could you please advise on potential causes or next steps to resolve this issue?

You dont need to tune for the intake in most cases, unless the diameter around the MAF is bigger/smaller than stock because then the MAF will read wrong and your engine will run like ass. An intake probably wont do much in your situation, other than make things louder and give suction noises but an intercooler might. You'd really be pushing the turbo if you want more than 260hp. Considering how weak the k03 is as far as reliability, I wouldn't push it any further since a properly tuned k03 will spin till the end of 2nd gear anyway. It's small and cant build boost past midrange like a k04 can, it's just not worth to overstress it. K03 accelerates hard, and I mean HARD from 2.2k onwards but lacks the top end oomph of the K04.

If you want more power, I'd swap to a k04. Been there, done that cause my k03 failed. Hot side cracked right around the wastegate and the turbo shaft had so much play, only the will of god was stopping it from coming out.

If you want to stay K03, you best bet is an aftermarket intercooler. It will keep temps lower and flow better than stock, maybe freeing up a bit of power.
