VW Golf GTi 1.8 Turbo

Also more good points. Mine had an ignition amplifier before I had it, and I fitted a green top temp sender shortly after buying it. The AGU is a tough old unit, and with a lightened flywheel and cable throttle it responded to the right foot better than any of my BMWs could hope to.
It's had an ignition amplifier replaced on it previously, not sure if a genuine part or not though. I'm gonna scan the car on vagcom today and see if any codes relating to a misfire come up anyway. If yes I think I'm going to replace it again. I have a few little bits to order from TPS and a new coolant temp sensor is one of them not sure if mine is green or black though.
Car has alaso had a clutch chane at some point but once I start with some kind of power upgrades I will be looking at vr6/g60 clutch and solid flywheel for sure.

cracking lumps the 1.8Ts had a mapped Cupra R for a few years and loved it,
definitely worth getting a few tweaks on it though,
On the huge list of bits I want to do definitely worth getting a few tweaks on it though,

The thing that caused misfire problems on my AGU was the ignition amplifier - thing in the airbox. Had three in the course of it's life. Oh and the dual temp sensor can play havoc with the running of the engine. Mine would run fine from cold, leave it 45 mins and then would be a git to restart and would run like a dog for ages. New temp sensor and it was spot on again.
I sold my 1.8T with 237k miles on the clock, engine had never been open and it was original turbo, It is still on the road somewhere, last may MOT'd with 287k on the clock.

I was out Saturday evening and my brakes locked up on me. Luckily, no accident happened, brakes seemed to go back to normal and all was well. Luckily for me I have already purchased my brake booster pipe.
So once I had finished my work for the day today, I had a quick swap over of the pipe. This is the pipe that comes out of the inlet to the bulkhead and connects to another pipe.
First off was removing the VW horrible one time use clips.
Now for the offending pipe... (This pipe was actually no longer attached to the rest of the vacuum system, obviously came off when my brakes locked up on me and explained the horrible idle)
Where it was supposed to be attached too...
The replacement in all its glory, nice and shiny too.
The idle on startup improved dramatically, the drive now seems smoother when not accelerating but not completely cured. I'm half now thinking it may be the ignition amplifier as it was not replaced with a genuine part.
I noticed my reverse lights were not working, so I removed the bulb from each side (one was led and one was standard but neither worked).
For some reason they still didn't work upon replacement. Anyone with any ideas as to why please throw them my way.
Of course when sorting one issue another arises, literally in a matter of minutes.
I'm already aware that I need a door lock module for my O/S/R and this door stays locked unless I need to open it then I do that internally. But when I got home from work the car was locking and unlocking on the remote. So had to lock the door with the key and see how that goes. Joys of a MK4 ringing bells.
Anyway a couple of photos I took a few mornings ago while letting the car warm up. (I have since replaced my number plates with a correctly spaced plate too)
More updates soon.

Crazy door locks on mk4 golfs is quite a well known issue. There are some joints where the solder fractures making intermittent connection. Usually will throw an error code. I ended up removing mine and re-soldering the joints, seem to recall it was the 6 joints where the main plug joined the circuit board.
Eventually though the remote locking failed, I used to have to unlock the door and start within 30 seconds before the alarm went off. I used to call it character

Pretty darn obvious, but did you check the fuse for the reversing bulbs?
Quite like the two-tone interior.
I haven't. I wasn't sure if they would be on a separate fuse? I'm leaning towards reverse light switch on the gearbox...Quite like the two-tone interior.

Yeah I had the issue on my mk4 a good few years back but lived with it. This time I don't want to live with it I want to try and resolve it Eventually though the remote locking failed, I used to have to unlock the door and start within 30 seconds before the alarm went off.

My Dad's had an Octavia, the bulb was out, replacement bulb didn't work.
The circuit board had some corrosion on it. .
Replacement board from ebay for 10 quid sorted it.
I will bare that in mind. From what I have seen it looks pretty clean. Gonna get a reverse switch first and hope that cures it, bit weird the other lights are fine but both don't work.The circuit board had some corrosion on it. .

Nothing exciting here, just keeping the thread alive.
Pollen filter changed spare half hour at the end of work..
Also changed my interior alarm sensor switch on the drivers side, bit fiddly with my big hands but hey ho.
Have priced up a few parts from TPS that I shall order soon.
I think I am going to pull the starter motor down, give it a clean and a grease. I'm not feeling comfortable with the people that have told me buying a new one, the noise will just happen again 6 or so months down the line due to drying out.
Couple options are to use CV grease or red grease. If you have a preferred option feel free to give me a heads up?
Pics soon. Hate taking phone photos ha.

Managed to get a couple more bits done today. One of my mates at work suggested doing the gearbox oil, at first I wasn't sure as I wanted to check the oil it took etc. But what the hell, it's a 16/17 year old 5 speed manual, anything in there is better than what was put in 90k ago I'm sure. Probably not been changed before. Regardless it can make do for a temp flush through oil.
Anyway I'm glad I did. It looked like hot chocolate.
This was the replacement for now..
75W-80
Last item on my service list to change was my fuel filter. The one on there was changed recently and for a genuine one. But for peace of mind and so I know when next due I changed it anyway and used the correct jubilee clamp.
Even had time to chuck in an air con bomb.
Now today I finally stuck my car on VAGCOM and too many fault codes for my liking. Some I'm already aware of, some I'm hoping are old faults that were not ever cleared before or relate to my current juddering issue.
- 18010 / P1602 - Power Supply Terminal 30 (Hopefully just a new battery required, it's had a new alternator)
- 00544 - Maximum Boost Pressure Exceeded (Could be the ignition amplifier that was changed previously, a friend has told me that it could be the N75 valve)
- 16500 / P0116 - Engine Coolant Temp Sensor On my list already
- 16514 / P0130 - Oxygen (Lambda) Sensor B1 S1 Could relate to my over fueling?
- 00953 - Interior Light Time Limit No idea, have noticed tonight the interior lights are not working, now can't think if there were before or not, my guess is they didn't
- 01334 - Door Control Module Rear Right This is the door that stays locked and is on my list
- 01335 - Interior Monitoring Sensors Hoping this is just related to the switch I changed over
- 00943 - Heated Exterior Mirror Drivers Side No surprise - it's an old car - didn't work on the passat either
- 01358 - Internal Central Locking Switch Drivers Side Implausible Signal Probably explains my remote being a c**t sometimes
- 00944 - Heated Exterior Mirror Passengers Side Again no surprise and that is the least of my worries for now
- 00930 - Locking Module For Central Locking Rear Left Linked to my remote locking not working I assume
Going to be working through the codes anyway, none are that serious in all honesty just annoying and I was aware of the majority so to speak, looks a lot more than it really is.
Any help regarding central locking and over boosting would be great.
Updates again real soon.

Don't you struggle to justify the expense?
What expense?I'm probably no more than £150 / £175 in so far, most expensive item being the spark plugs...
The expensive part is going to be upgrading parts, mainly silicone hoses but its a one off job more or less and I like the fact of that.
I've had newer cars and I've came back down to one of these, I prefer this era of car.

Not really updated this too much. Been picking up a few second hand parts to freshen up the car. This including brakes, bodywork, mounts and interior bits. This included a 360 mile round trip for me as I went with a friend in his van kindly enough. I luckily also got bargains on my parts.
I have picked up a bonnet / front bumper / rear bumper in my colour, just waiting on getting 2 wings now. Never got any photos of these just as yet.
Some black carpet / parcel shelf / glovebox and other various plastics.
I mentioned previously that my dogbone mount that is currently on the car is a euro car parts special and has started to fail, even though it was replaced recently. On that note I collected an original dog bone mount, took it apart and cleaned it up. This one is now being polybushed. I have put a Super Pro circular poly bush in one end and now just need to order the 2 poly bushes for the opposite end and can fit to my car.
I managed to get my hand on a set of MK1 Audi TT front and rear brakes for a steal, also round the corner to my work which was even better.
This takes my front brakes from 288mm up to 312mm and takes my rear brakes from 232mm solid discs to 256mm vented discs.
Upon collection..
Spent some free time at work taking the caliper apart, removing the sliding pins, piston & seals etc. The piston was in pretty condition apart from the rusted section on the outside. But no scoring internally. Could do with maybe sticking the calipers in a parts washer to degrease them but unfortunately we dont have one at my place.
Some before photos for comparison.
After...
Mate at work took a photo of me getting my hands dirty (even with gloves on) to prove I get stuck in ha.
One last update. Starter motor.
I chose to avoid paying out a large chunk of money for a new starter motor. Took some advice online to grease up the old unit. To cut a long story short I used CV grease. The noise has gone on most start up but still appears on some. So I am going to buy a 2nd hand unit, take apart etc but clean it out and use red grease instead as advised. No harm in trying something else ha.
The dry motor that causes the squeal...
Greased...
Wasn't a fun job to do but has certainly helped.
I will be cleaning up the other 3 calipers & carriers now. Cleaning up all of the interior plastics and carpet ready for fitting. Finish polybushing the dogbone and get that fitted. Hopefully I get my 2 wings that I have lined up and can swap the front end over.
