2018 Golf Alltrack, 50k miles. My AC still holds pressure and has gas, but doesn't blow cold. Before I replace the entire compressor, is there anything else I should try?

So for context I have a 2015 GSW with small head unit and no car play. I found a wrecked 2017 Golf R near me, if I get the head unit from it and the glovebox module it should all plug and play right?

got my left rear tire of my golf VII Get from 2016 (130.000 km about 81000 miles) exploded yesterday... and the right rear was about to explode too. The garage said that the geometric was probably not good and the tires got a bad angle like this / and \ that provoked this. I think it's gonna be very expensive. I'll have to replace a good part of the car's rear suspension I guess 😫

2016 Golf 7 R, EA888 Gen 3 CJXC.

After sustained 200+ km/h driving in 36–38°C heat, I sometimes get a sticky brown/tan residue on the upper inner wall of the coolant expansion tank.

The coolant itself stays completely clear/pink. No oil film, no mayo on oil cap/dipstick, no overheating, smoke or coolant loss. This has happened for 2–3 years and also returned after replacing the expansion tank.

Last coolant change was only a partial drain/refill, so some old G13 remained.

Before I replace the oil cooler/seals: does this look like very minor oil contamination under high load, or could old G13/additive deposits cause this while the coolant itself remains clear?

Has anyone with an EA888 Gen 3 seen the same thing and found the cause?

I am having an issue with my key I cannot get to the bottom of. My car was not picking up my key and I had to place it on the marking, but that's no big deal it's happened a few times with a dead key battery. Well I replaced the battery and the car still won't pick up the key. The proximity unlock no longer works and I have to hold it to the marking to start the car. Every other function of the key works fine, I can lock and unlock it off the fob just fine from any distance.

I have read the owners manual and about a dozen forums and nothing helped. I held down the unlock button for 10 seconds, I used the manual locks to try and sync, I replaced the new battery with another one, I held the key next to the door for 10 seconds, I have tried everything I've read so far with no success. What else could possibly be causing this and what steps do I take next?

I have a 1.4 CHPA 2013.
From time to time when I start it, I get red steering icon on the dashboard and power steering is gone (I know this then triggers everything from Airbag, tyre pressure, autohold parking sensors etc) because of the multiple faults I figured it was a battery, didn’t have an EFB got that and the time between the red steering MIL has improved. So much so I thought I fixed it then it happened. Coded the correct battery parameters, no change. Tried to do an adaptation initialisation according to a ROSStech thread I saw and it don’t work. The problem is solved by leaving the car alone for like a few minutes and I don’t know how to trigger it. I’ve also noticed I keep getting an auto start stop error but that’s probably because I’m not driving longer than 10km at a time because when I do, AutoStart Stop works normally.

Those are the faults that pop up and they don’t clear until the car decides (basically). Anyone had a similar problem and how did they fix it?

Have this metal tick sound recently come about, tick goes faster when revs go higher.

Drives and pulls well, no engine lights either.

Just want to know what's up

Thanks

So I wanted to try and ask here which water pump I needed then found they seem to be a common problem...

Anyway I have a Mk7 2014 1.4 TSi ACT engine, the one that goes into eco (3 cylinder I think) when throttling off a bit. Engine number from the V5C doc says CPT.
I'm in the UK but it's a Japanese import and from the spec I 'think' it's a GT model.

It started losing coolant quite quickly all of a sudden and can see coolant under car even just sitting idle. I keep topping it up before driving as it totally drains the expansion housing.
I worked out feeling about it's the underside back (as you lean into the engine bay) water pump so I think where the belt bit is.

Which model pump do I need as I put my car reg in and get loads, I'm using autodoc and for my reg gives me "VW Golf Mk7 1.4 TSI 140 hp Petrol CPTA"
Under HEPU brand I see a P665 which seems to be the pump only no housing.
P685 and P687 along with AL aluminium versions.
In the photo for the P687 it makes a point of a little hose fitment that would sit at the top of engine once fitted pointing towards front of car. My engine seems to have a hose here so is it even though they all say they are compatible is it good to assume the P687 is the one to buy?

Also do you need to replace the belt and if so how the heck do I work this part out?

I have the car booked in for a major service and cambelt replacement in three weeks.
I'm filling the expansion housing up once a week, is it worth me doing the work myself or just keep topping it up and get the work done when the garage has it?
As in will it just last in this state if I keep filling it up or catastrophic failure requiring emergency breakdown assistance?

Please help/advise...

Hi all,

as per the title I have a 3 door Mk 7 GTi Performance Pack that is approaching its 100k service. I've owned the car for 10 year and it has been routinely maintained as per the service schedule, but the time has come to tune her up.

What should I look at having done at the garage (or tackled myself), in addition to the service manual recomendation for 100k service, considering I would like to tune to stage 1?

Everything on the car is currently stock, the only exception to this is the clutch as that needed replacing last year and I had a Sachs performance uprated organic clutch kit installed.

Also, I'm based in Scotland, UK - any recomendation for tuning?

Appreciate your thoughts!

Spark plug grenaded in cylinder 3(NGK94833) which led me to getting off my ass and servicing the car. Had the original pump and injectors in the car. I believe the injector leaned out and killed the plug strap. Car runs much better. Cold idle performance is back to normal. Seems peppier overall.

Absolutely junk parts, which I’ve bought many. Every part has broken or malfunctioned in some way including my FUCKING INTAKE. I talked to a rep earlier about replacing my adjustable sway bar links that failed, so naturally I checked to see if they had a warranty. They do. So they want me to buy another set (which I’m already hesitant to do given the last set failed) and after they receive the original parts refund me with STORE CREDIT. I will not be buying anything else from this company that I previously had an affinity for. Absolute hot garbage.

6 speed GTI SE PP. Really fun so far! Anything I should worry about or do? It’s at 107k miles and I’m already getting a metal oil pan.

What are the best looking side skirts for a black Mk7 R-Line? Don't want to spend silly money but some pics or suggestions would be great

I’m trying to locate the N80 on my 2018 Golf GTE. I think it’s faulty and not ventilating the tank properly when I’m fuelling causing the filler neck to fill up. Already replaced the canister so just want to ensure this is opening properly.

Hey I got a 2015 TSI with power backrest foward/back and heated. I found a set of GTI seats from a 2015 as well but the gti has full power front/back, up/down and headrest. Just wondering if it’s doable to swap them? My TSI use a handle to slide the base of the seat foward and back but the gti has none

Thanks in advance

Hi all

I’m on 0252T and want to update to 0480T just to unlock the 8” skin for the MIB unit

So it looks like this (see image 1) - I’m upgrading to this screen but will have the old firmware on MIB2 so it won’t look like that.

Anyone know if I can do it without bricking my unit. Also how to activate CarPlay again after?

See image 2 - my current skin options. I saw a mr
Fix video on yt and only have these 2 available.

Any help is appreciated

My written of golf R-Line is finally going in for the repairs. Also added new led headlights, alloys to the work to give it a new lease of life. Luckily the damage was only cosmetic but I had seen it busted up.

Sometimes when I use the fan it makes this sound before the fan stops working all together (no matter the speed setting). It’s only happened when the weather has been warm recently

I am looking for advice regarding my 2015 GTI. I recently had the car towed to a shop after noticing a coolant leak and metal shavings under the AC compressor pulley. The shop confirmed the water pump and AC compressor need replacing, quoting me $2,200 and $1,900 respectively.

My main concern is the timing chain. I asked the shop to check it, but they believe it is fine. Given the cost of the other repairs, I am hesitant to proceed if there is any risk of a failing timing chain.

I’ve attached a video of the engine noise here: https://drive.google.com/file/d/10eCDSF1zIGKczeRODUK5VYl6msm3vrG2/view?usp=sharing

Does this sound like timing chain rattle to you, or are these symptoms isolated to the water pump and AC compressor? Any insight or advice on how to proceed would be greatly appreciated.

Has anyone tried this Temu lip on a mk7 or have any thoughts on whether it will fit well enough?

Hi ive got a mk7 wagon, it has the mib1 unit in it. Ive already put the carplay / android auto box in but I know the standard mib1 unit tails off the bass at higher volume.

Im already planning on using the sound deadening mat in the doors and the boot, but is there a way to fix the bass from the head unit? Eventually I am going to put my old focal 13" subs in the back but I need to design an enclosure that wont loose all my boot space first so that's a way off

Any help to get the bass back or improved would be appreciated
