Mk5 General Area / Re: Back in a MK5 GTi, anything to urgently do?
« Last post by darren4 on August 29, 2025, 02:04:44 pm »
Might as well check the cam Phase position - VCDS, Engine > Block 93, should be near or close to 0KW

Whats this checking for, sorry if thats a silly question

If you think the rear is brutal, you should see the price of the front. Pretty sure I paid about £120 for mine.

It fairly cured the sagging though.

Mk5 General Area / Headliner Repair Trim Piece
« Last post by Jons1001 on August 29, 2025, 12:06:09 pm »
My headliner is sagging around the rear interior light. I found these online but nowhere seems to have stock anymore. Also messaged the manufacturer but no response.



Does anyone know where i might be able to get hold of one? The price of £70 is a joke though for a bit of plastic, would be great if we could get hold of the specs so we could 3d print them!

Thanks

Mk5 General Area / Re: Mk5 GTi stage 1 fuel pressure problems

Ty for the reply
I did the filter swap myself last year and did check the pressure requirements beforehand so the filter is the correct one.
Here are the logs:

I'm doing tests on the n80 today and checking if the charcoal canister is clogged because there is a hiss when opening the fuel cap.

How do I test the controller on the fuel tank lid?

Check the part number of your old pump and buy based off of that. IIRC you need a 6 bar pump and a 6.6 bar filter.

Log the low pressure side with vcds next time you go for a drive so you can check what the pump is doing. Could be the pump, could be the controller or could be a worn out HPFP lobe. Even just a slight bit ow wear on th elobe can mess with the regulator open/close times and in turn mess up your fuel pressure.

Mk5 General Area / Mk5 GTi stage 1 fuel pressure problems
« Last post by Lassebongo on August 28, 2025, 12:15:19 pm »
Hi!
Im new here so if the thread is posted in the wrong section let me know.

Ive got a 2008 Gti mk5 stage 1 with fuel pressure problems.
On hard pulls it jerks and in the VCDS logs the pressure drops from 110 bar to 7(with the new HPFP, the old one went up to 129 bar and dropped)
A local company loaned me a HPFP which is swapped but didnt solve the problem.
Fuel filter swapped last year.
The cam follower is also new, doublechecked and its in pristine condition.
There are no leaks from what i can see, atleast around the visible fuel rails and HPFP.

So whats left is the in tank pump and im pulling it out today but i dont know what to look for  :scared:

Could there be anything else causing this problem or can i just swap out the in tank pump and the problem should be solved ?
Can the in tank be repaired ?
Is a 4 bar pump enough?

Mk5 General Area / Re: Temp gauge dropping when heaters on
« Last post by Mk5gti on August 28, 2025, 08:12:16 am »
So my issue is the needle drops when I turn heaters on
Both thermostats have been done and temp sensors using genuine parts, while driving the needle doesn’t drop, the needle will only drop at idle with heaters on

I had the same issue years ago. Also car never reaching 90 degrees fully in winter or dropping from 90 when constant highway speeds. Issue was thermostat.

Performance Modifications / Re: Cracked air filter housing on engine cover
« Last post by Joeb3006 on August 28, 2025, 07:06:59 am »
I agree. I'd stick to the std intake and use a good quality std filter and just change it every year. The std intake gets nice cold air right from the leading edge of the bonnet, most "cold air" kits seem to get the air from inside the warm engine bay  :stupid:. The same intake was used on other VAG group cars so you don't have to stick to a VW one.

A stage1 tune really does make a difference, I had a Superchips Bluefin one on mine and it's been perfect and really gives a nice load of mid range wallop for overtaking, I found as std the car felt a bit flat. If the cars been as well maintained as you say then I wouldn't worry having a stage 1 tune added as long as it's by someone reputable.

R8 coils are mainly cosmetic, buy them if you want if yours fail but otherwise I'd leave them alone and save your money.

Worthwhile checking the HPFP cam follower but if it's done over 245k then someone's been changing it in the past, same with the oil pick-up, if it's had it's oil changed every 6k then sludge is unlikely to be a problem.

Good luck.
That’s perfect thanks. I have a good tuner by me who specialises in VAG so I’ll be taking it to them when I get it done!

Welcome,

That's a whole lot of views on your post and not a lot of answers !

I'd 100% be fitting an uncracked standard intake. There will be plenty on ebay. Fix what you know is broken right? If keeping the intake standard, fit a OEM Edition 30 filter. It's a little thinner than the standard GTI one. I've toyed with the idea of a CAI system, but I really do not want additional noise or to lose the engine cover. Standard airboxes are good for quite high BHP figures anyway.

I'd not bother with R8 coils, unless you want the aesthetic of the red when you open the bonnet. I went for standard OEM coils. What will benefit you in that area is a set of iridium spark plugs. I forget the make, NGK maybe? I could look that up if you need.

Stage One remaps really wake these things up. Just beware that a worn clutch will manifest itself fairly quickly post remap. I faced this problem and opted to fit the TTRS clutch unit with new flywheel. Expensive, but totally OEM feeling and good for a fair bit of power. I'd not worry about mileage covered on the engine already though. If it's been maintained it'll likely be fine.

In regard to maintenance, which I'm just throwing in here, has the engine had the sump dropped and oil pickup replaced? Has the cam follower been checked / replaced? Please consider these prior to anything else, as they're a potential killer of these engines.

Good luck !

Thanks for the reply! I appreciate the insight and you passing on your knowledge
I’ll stick to the standard one, as I too like the look with the engine cover.
As for the maintenance. I’ve actually replaced the cam follower, PCV valve and pipes, the charcoal canister and EVAP purge valve, and I have had the sump off and replaced the pick up and the oil pressure switch.

I know it’s overkill but reading all the “common” issues with the car I wanted to get them all done and out the way so I didn’t have to worry.

As for tuning. With you explaining the engines are strong, I think I’ll go for a stage 1. I don’t push it often but like you say, when I want to, that little bit extra power will be nice!

Thanks for getting back to me!

Happy motoring
