Mk5 General Area / Last Ditch Effort.....
« Last post by conradius593 on June 29, 2026, 07:50:28 pm »Hey guys, wondering if anyone can point me in a direction for a last ditch effort to get my car running again before i call the junk yard to come get it.
2008 (Prod Date- 10/07) MKV GTI BPY FSI 2.0T Manual ~225,000 Miles on dash
History-
Blew head gasket years ago- had entire top end rebuilt, turbo rebuilt, all timing belt components and cam chain components changed including phaser. Did the work myself along side my lead tech at my mom and pop shot that i was the service manager at. By no means a master tech but went to school for automotive tech and know for the most part what I am doing.
Car ran fine for about 6 months then started getting an intermittent P0016 code. Changed the Cam sensor, Crank Sensor, VVT soleniod. Took it to a local euro shop as I wanted to stop throwing parts at it and wasting time. Shop had car for a few weeks, tech was frustrated with it, set timing four times, verified timing was fine to begin with on both sides of engine. Ended up giving me a diagnosis of a bad engine wiring harness. Torn, chaffed somewhere. Suggested that I just replace the motor with a used one that had the harness with it.
I didnt want to go this route because I have already essentially rebuilt the entire top end and put a lot of money into it and only got a year out of it...So i took to the internet and found a harness on ebay. The part number was 06f972619AR- which i did not research greatly and i found out was for a DSG transmission. Stupidly i put the entire harness in the car before verifying. All connectors lined up just fine but when I went to start the car it would run for a few seconds then die. Was getting code p3089 (communication with LPFP). Well surely did not have that issue before so I knew it was the harness. Fast forward through research i am confident that I have the correct harness. Just got delivered the other day. Part number 06f972619AQ. Everything is telling me this is MKV BPY FSI manual harness.
Well i get it in today and sure enough the same exact issue. Car starts hard, runs for maybe 10-20 seconds and dies. Threw the same code- P3089. Maybe a sh*t coincidence happened? This issue came about as harness was having issue? I wasnt convinced but started testing. Have 12v power at the LPFP- can hear the pump priming- jumped 12v power to pump directly and it runs. So, its gotta be the control module right? NOPE. Swapped it out and its the same thing. Just got a nice quote for $390 to junk this pile of crap and i am about to hit accept and move on. Anyone have any last ditch efforts for me to attack? I had absolutely zero issues aside from the P0016 code prior to swapping the harness. So i am still leaning that the harness is wrong. But all connectors have a home. I verified i have the right connectors on right sensors with wiring diagrams. I am at a complete loss. I am putting way too much time and energy into an 18 year old car.

A lot of the bolts are available as aftermarket, not sure about the subframe bolts. Can't see why not though.
I Use Autodoc to find the parts and then use the part number to find them on Ebay.

Most of the arms and stuff came with bolts and I’ve got the rear subframe bolts already, will get it all together and see what’s missing from then on.
Got the arches cleaned down with bilt hamber wheel cleaner and some citrus prewash, they aren’t as bad as I first thought, but defo some areas to pay attention to:
All parts are at the powder coating place now, so plan going forward is to great all this stuff treated and repainted, there is also a small rust hole which I’ll patch up before the painting.
Hoping to have everything done by the end of next month - also was going to just get the OEM anti roll bars coated and put back on as there is nothing wrong with them, just not sure if I should go H&R or something if I am going this far haha

A good alternative to anti lift is the s3 wishbone rear bush as it's solid rubber and not voided like the gti version(It needs pressing into the gti aluminium console as the s3 one is different) That's what I had fitted on my last gti.
My edition 30 came with anti lift but I have no idea what brand it is.

To fit the aluminium hubs you will need the longer bolts that hold the brake carrier and shouldered nuts for the bottom joints and track rod ends.
I have the part numbers if needed .
Are you fitting anti lift bushes at the front?
Haha oh well, too late now but cheers anyways!
Ok no worries, cheers for the advice like, aye the part numbers would be good if you’ve got them, I might leave it for now since I’ve got all of the bits already and I’ve spent a fortune already haha, but defo useful for future, especially if I end up mapping it (it’s stock at the moment)
Same story for the anti lift bushings, probs will do but at a later date - do they give much advantage? I’ve read reviews of them like but was unsure if it made much difference on a stock car?
Plan at the moment is to just get everything as new as possible as a good base

« Last post by rex on June 24, 2026, 05:48:30 pm »With the oil consumption problem hopefully fixed, I continued with the maintenance items needed for my next track day (July 24th hopefully):
- new clutch
- new engine mounts
- new gearbox oil
All went smooth.
The OE clutch plate and pressure plate were worn but not excessively (this is after ~150k km). But the pressure release bearing was a bit shot...
The OE clutch is Sachs, very similar to the OEM I bought.
The engine mounts were in a good condition but I just don't want to have any issues shifting so I changed them with Lemforder ones:
The gearbox oil was very expensive, about 100 GBP/litre from the Dealership, without discount... With discount it got to ~60 GBP.
Now the clutch feels surreal. At first I thought the slave cylinder was leaking or not attached or something... It is so light and smooth is feels like a clutch used in a simulator.
After I took the car back home, I had to switch to the Porsche (as to pick one of my kids from kindergarten) and the clutch in the Porsche feels like a proper one, not a toy one :).
Hopefully all the problems are solved and I am going to enjoy the car for a long time :).
