Mk5 General Area / Re: GTI low pressure fuel pump change

Autodoc is fine. Ordered a lot from them and it's def genuine stuff.

They were sold out of the VDO ones when I had looked the other day.

I was tempted by those brands but just decided to look for a newish genuine one with the latest PN. This one I got is 6 years old low miles compared to my 20 yr old one and 120k miles for £31......could not argue with that.

Waaw!👍🏻 Amazing!
Now that’s a proper track car that you’ve build!👍🏻
Forget the M3, Keep that as original as possible😎👍🏻
No rush with your track car, when funds come, you car finish it😉

Thanks dude!

I also cant find a VDO pump anywhere but I can get Pierburg or Bosch units. Any clue if these would be ok or does it have to be OEM?

Also do update on how it cold starts next time, since I'm having some issues and the pump is the next thing on my list.






Edit: Found this one on Autodoc. I've heard mixed reviews about Autodoc. Some say it's aight, other say they are knockoff parts. Price is 110 euros.

Got some time last night to start with the rear suspension…😎

Changed the anti roll bar and drop links with all new nuts and bolts along with
the Tyrolsport subframe rigid collar kit.
Tonight the B16’s are next….



Some before and after pic’s

















All went pretty smoothly until the old left drop link decided to break / round off🙄🤬
So… grinding time😅 and 15min later all was loose👍🏻
Got all the nuts and bolts torqued up and went for a drive to see / feel if my work was all good😁

Tonight I’ll get the shocks and springs ready to be mounted…

Car started straight away and it felt like it did it with less effort. Yet to do a proper cold start, but happy with what has been achieved

Mk5 General Area / GTI low pressure fuel pump change

Well what started as a general investigation, ended up as project.

Decided to have a look into the LPFP to improve the cold starts and suspected I had a tired back flow valve that was bleeding fuel pressure. I also discovered i had an old style pump due to having an early GTI that was prone to overheating and was never changed.

I had already changed the pump controller to a new one as they too were prone to overheating and going pop.....my wife's golf did this on a journey and the car almost set on fire.

The new genuine pump was £270 + VAT so more than i wanted to spend since doing the cam chain job, a new VDO like genuine was out of stock everywhere  and far less so went for the next best thing......a genuine secondhand one.

The new part number is 1K0919051DB and got one off a 1.4TSI Scirroco 2018, so a lot newer than mine and far less miles done on it too for £31 BARGIN!

Disconnect the pump fuse. 15 amp number 27 started the car until it died, then disconnected the negative battery lead.



Removed the back seat and was amazed how dirty the top of the pump was



Removed the ring, pump and seal of which I noticed was pinched from factory. Old pump ended in AE so definitely original






New elring pump seal and also the new to me pump back in








While I was there i also changed the fuel filter

Fuse back in and started the car

Mk5 General Area / Essex Mapper k04 Conversion Help

« Last post by K03MK5 on November 16, 2024, 09:35:26 am »

Hi there have a Gti mk5 k04 conversion running 345bhp.  Basically on cold starts and if the car has been left for a couple of hours it seems to misfire around 4k then it’s completely fine.  Also on cold starts etc idle is very lumpy and rough.   Codes from my basic scanner brings up p2293 p2294 and a cylinder 4 misfire.  Sparks, coils and pcv have been replaced.   It was running completely fine on a stage 1 before mapping.  The turbo has been recently rebuilt with an uprated thrust bearing.  If a mobile mapper in the Essex area could help that would be great.   Any ideas ?  Thanks.

Decided to allocate some funds to the car again this month and did a suspension refresh. New Lemförder sway bar end links, new Bilstein B4 sport front and rear shocks, Eibach Pro-Kit coils from my old Jetta (7k km on them tops) and new dust/mud guards for the shocks along with new Lemförder strut mounts front and rear.



Car feels a lot more stable and wheel hop went away for the most part. It's slightly stiffer than my factory sports suspension but overall seems more comfortable for some reason. It's stiffer when going over speedbumps for example but a lot more comfortable when driving on a slightly uneven road. Next up I'll probably get a 034 Motorsport solid rear sway bar for the suspension as the car still understeers. Drove a friend's Audi A4 B7 and oversteer feels better than understeer.

Also changed to winter tires since it snowed the other day.

Before


After







I can definitely see why Eibach isn't selling black coils for the GTI. This thing is actually slightly taller in the front than stock (could just be cause of the new shocks not having more than 300km on them so far) and the rear doesnt have that much height difference. The stiffness difference compared to stock wouldn't be worth it for a lot of people. Red coils would serve their purpose better.

Edit: Used photoshop to line up the wheel on the before-after photos. Front is the same height as before the suspension update, rear is lower.
